# الوكلاء والأدوات
[[open-in-colab]]
### ما هو الوكيل؟
يمكن للنظم اللغوية الكبيرة (LLMs) التي تم تدريبها على أداء [نمذجة اللغة السببية](./tasks/language_modeling.) التعامل مع مجموعة واسعة من المهام، ولكنها غالبًا ما تواجه صعوبات في المهام الأساسية مثل المنطق والحساب والبحث. وعندما يتم استدعاؤها في مجالات لا تؤدي فيها أداءً جيدًا، فإنها غالبًا ما تفشل في توليد الإجابة التي نتوقعها منها.
يتمثل أحد النهج للتغلب على هذا القصور في إنشاء "وكيل".
الوكيل هو نظام يستخدم LLM كمحرك له، ولديه حق الوصول إلى وظائف تسمى "أدوات".
هذه "الأدوات" هي وظائف لأداء مهمة، وتحتوي على جميع الأوصاف اللازمة للوكيل لاستخدامها بشكل صحيح.
يمكن برمجة الوكيل للقيام بما يلي:
- وضع سلسلة من الإجراءات/الأدوات وتشغيلها جميعًا في نفس الوقت مثل [`CodeAgent`] على سبيل المثال
- التخطيط للاجراءات/الأدوات وتنفيذها واحدة تلو الأخرى والانتظار حتى انتهاء كل إجراء قبل إطلاق التالي مثل [`ReactJsonAgent`] على سبيل المثال
### أنواع الوكلاء
#### الوكيل البرمجي (Code agent)
يتمتع هذا الوكيل يتبع خطوات محددة: أولًا، يخطط لسلسلة من الإجراءات التي يريد تنفيذها، ثم شفرة Python لتنفيذ جميع الإجراءات في نفس الوقت. وهو يتعامل بشكل أصلي مع أنواع مختلفة من المدخلات والمخرجات للأدوات التي يستخدمها، وبالتالي فهو الخيار الموصى به للمهام متعددة الوسائط.
#### وكلاء التفاعل
هذا هو الوكيل الذي يتم اللجوء إليه لحل مهام الاستدلال، حيث يجعل إطار ReAct ([Yao et al.، 2022](https://huggingface.co/papers/2210.03629)) من الكفاءة حقًا التفكير على أساس ملاحظاته السابقة.
نقوم بتنفيذ إصدارين من ReactJsonAgent:
- [`ReactJsonAgent`] يقوم بتوليد استدعاءات الأدوات كـ JSON في إخراجها.
- [`ReactCodeAgent`] هو نوع جديد من ReactJsonAgent يقوم بتوليد استدعاءات أدواته كمقاطع من التعليمات البرمجية، والتي تعمل بشكل جيد حقًا مع LLMs التي تتمتع بأداء قوي في البرمجة.
> [!TIP]
> اقرأ منشور المدونة [Open-source LLMs as LangChain Agents](https://huggingface.co/blog/open-source-llms-as-agents) لمعرفة المزيد عن وكيل ReAct.
![إطار عمل وكيل ReAct](https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/blog/open-source-llms-as-agents/ReAct.png)
على سبيل المثال، إليك كيف يعمل وكيل ReAct Code طريقه من خلال السؤال التالي.
```py3
>>> agent.run(
... "How many more blocks (also denoted as layers) in BERT base encoder than the encoder from the architecture proposed in Attention is All You Need?",
... )
=====New task=====
How many more blocks (also denoted as layers) in BERT base encoder than the encoder from the architecture proposed in Attention is All You Need?
====Agent is executing the code below:
bert_blocks = search(query="number of blocks in BERT base encoder")
print("BERT blocks:", bert_blocks)
====
Print outputs:
BERT blocks: twelve encoder blocks
====Agent is executing the code below:
attention_layer = search(query="number of layers in Attention is All You Need")
print("Attention layers:", attention_layer)
====
Print outputs:
Attention layers: Encoder: The encoder is composed of a stack of N = 6 identical layers. Each layer has two sub-layers. The first is a multi-head self-attention mechanism, and the second is a simple, position- 2 Page 3 Figure 1: The Transformer - model architecture.
====Agent is executing the code below:
bert_blocks = 12
attention_layers = 6
diff = bert_blocks - attention_layers
print("Difference in blocks:", diff)
final_answer(diff)
====
Print outputs:
Difference in blocks: 6
Final answer: 6
```
### كيف يمكنني بناء وكيل؟
لتهيئة وكيل، تحتاج إلى هذه الوسائط:
- نموذج لغوي كبير (LLM) يشكل المحرك الأساسي للوكيل. الوكيل نفسه ليس النموذج اللغوي، بل هو برنامج يستخدم النموذج اللغوي كمحرك له.
- موجه النظام (system prompt): هذه هي التعليمات التي يتم إعطاؤها للنموذج اللغوي لإنشاء مخرجاته.
- صندوق أدوات (toolbox) يختار الوكيل منه الأدوات لتنفيذها
- محلل (parser) لاستخراج الأدوات التي يجب استدعاؤها من مخرجات النموذج اللغوي LLM والأدوات التي يجب استخدامها
عند تهيئة نظام الوكيل، يتم استخدام سمات الأداة لإنشاء وصف للأداة، ثم يتم دمجها في موجه النظام الخاص `system_prompt` للوكيل لإعلامه بالأدوات التي يمكنه استخدامها ولماذا.
للبدء، يرجى تثبيت `agents` الإضافية لتثبيت جميع التبعيات الافتراضية.
```bash
pip install transformers[agents]
```
قم ببناء محرك LLM الخاص بك من خلال تعريف طريقة `llm_engine` التي تقبل قائمة من [الرسائل](./chat_templating.) وتعيد النص. يجب أن تقبل هذه الدالة القابلة للاستدعاء أيضًا معامل `stop` يشير إلى متى يجب التوقف عن التوليد.
```python
from huggingface_hub import login, InferenceClient
login("<YOUR_HUGGINGFACEHUB_API_TOKEN>")
client = InferenceClient(model="meta-llama/Meta-Llama-3-70B-Instruct")
def llm_engine(messages, stop_sequences=["Task"]) -> str:
response = client.chat_completion(messages, stop=stop_sequences, max_tokens=1000)
answer = response.choices[0].message.content
return answer
```
يمكنك استخدام أي طريقة `llm_engine` طالما أنها:
1. يتبع تنسيق [رسائل](./chat_templating.md) لإدخاله (`List [Dict [str، str]]`) ويعيد `str`
2. يتوقف عن توليد المخراجات من التسلسلات التي تم تمريرها في معامل `stop`
أنت بحاجة أيضًا إلى معامل "الأدوات" الذي يقبل قائمة من "الأدوات". يمكنك توفير قائمة فارغة لـ "الأدوات"، ولكن استخدم صندوق الأدوات الافتراضي مع معامل اختياري `add_base_tools=True`.
الآن يمكنك إنشاء وكيل، مثل [`CodeAgent`], وتشغيله. ولتسهيل الأمر، نقدم أيضًا فئة [`HfEngine`] التي تستخدم `huggingface_hub.InferenceClient` بشكل مخفى.
```python
from transformers import CodeAgent, HfEngine
llm_engine = HfEngine(model="meta-llama/Meta-Llama-3-70B-Instruct")
agent = CodeAgent(tools=[], llm_engine=llm_engine, add_base_tools=True)
agent.run(
"Could you translate this sentence from French, say it out loud and return the audio.",
sentence="Où est la boulangerie la plus proche?",
)
```
هذه الميزة ستكون مفيدة في حالة الحاجة الملحة! يمكنك حتى ترك معامل `llm_engine` غير محدد، وسيتم إنشاء [`HfEngine`] بشكل تلقائي.
```python
from transformers import CodeAgent
agent = CodeAgent(tools=[], add_base_tools=True)
agent.run(
"Could you translate this sentence from French, say it out loud and give me the audio.",
sentence="Où est la boulangerie la plus proche?",
)
```
لاحظ أننا استخدمنا معامل "sentence" إضافي: يمكنك تمرير النص كمعامل إضافي إلى النموذج.
يمكنك أيضًا استخدام هذا للإشارة إلى مسار الملفات المحلية أو البعيدة للنموذج لاستخدامها:
```py
from transformers import ReactCodeAgent
agent = ReactCodeAgent(tools=[], llm_engine=llm_engine, add_base_tools=True)
agent.run("Why does Mike not know many people in New York?", audio="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/recording.mp3")
```
تم تحديد موجه النظام ومحلل المخرجات تلقائيًا، ولكن يمكنك فحصهما بسهولة عن طريق استدعاء `system_prompt_template` على وكيلك.
```python
print(agent.system_prompt_template)
```
من المهم أن تشرح بأكبر قدر ممكن من الوضوح المهمة التي تريد تنفيذها.
كل عملية [`~Agent.run`] مستقلة، وبما أن الوكيل مدعوم من LLM، فقد تؤدي الاختلافات الطفيفة في موجهك إلى نتائج مختلفة تمامًا.
يمكنك أيضًا تشغيل وكيل بشكل متتالي لمهام مختلفة: في كل مرة يتم فيها إعادة تهيئة سمتي `agent.task` و`agent.logs`.
#### تنفيذ التعليمات البرمجية
يقوم مفسر Python بتنفيذ التعليمات البرمجية على مجموعة من المدخلات التي يتم تمريرها جنبًا إلى جنب مع أدواتك.
يجب أن يكون هذا الأمر آمنًا لأن الوظائف الوحيدة التي يمكن استدعاؤها هي الأدوات التي قدمتها (خاصة إذا كانت أدوات من Hugging Face فقط) ووظيفة الطباعة، لذا فأنت مقيد بالفعل بما يمكن تنفيذه.
مفسر Python لا يسمح أيضًا باستدعاء دوال بشكل افتراضي خارج قائمة آمنة، لذا فإن جميع الهجمات الأكثر وضوحًا لا ينبغي أن تكون مشكلة.
يمكنك أيضًا الإذن باستيرادات إضافية عن طريق تمرير الوحدات النمطية المصرح بها كقائمة من السلاسل في معامل `additional_authorized_imports` عند تهيئة [`ReactCodeAgent`] أو [`CodeAgent`]:
```py
>>> from transformers import ReactCodeAgent
>>> agent = ReactCodeAgent(tools=[], additional_authorized_imports=['requests', 'bs4'])
>>> agent.run("Could you get me the title of the page at url 'https://huggingface.co/blog'?")
(...)
'Hugging Face Blog'
```
سيتم إيقاف التنفيذ عند أي رمز يحاول تنفيذ عملية غير قانونية أو إذا كان هناك خطأ Python عادي في التعليمات البرمجية التي تم إنشاؤها بواسطة الوكيل.
> [!WARNING]
> يمكن لـ LLM توليد شفرة برمجية عشوائية سيتم تنفيذها بعد ذلك: لا تقمب استدعاء أى دوال غير آمنة!
### موجه النظام
ينشئ الوكيل، أو بالأحرى LLM الذي يقود الوكيل، يولد مخرجات بناءً على موجه النظام. يمكن تخصيص موجه النظام وتصميمه للمهام المقصودة. على سبيل المثال، تحقق من موجه النظام لـ [`ReactCodeAgent`] (الإصدار أدناه مبسط قليلاً).
```text
You will be given a task to solve as best you can.
You have access to the following tools:
<<tool_descriptions>>
To solve the task, you must plan forward to proceed in a series of steps, in a cycle of 'Thought:', 'Code:', and 'Observation:' sequences.
At each step, in the 'Thought:' sequence, you should first explain your reasoning towards solving the task, then the tools that you want to use.
Then in the 'Code:' sequence, you should write the code in simple Python. The code sequence must end with '/End code' sequence.
During each intermediate step, you can use 'print()' to save whatever important information you will then need.
These print outputs will then be available in the 'Observation:' field, for using this information as input for the next step.
In the end you have to return a final answer using the `final_answer` tool.
Here are a few examples using notional tools:
---
{examples}
Above example were using notional tools that might not exist for you. You only have access to those tools:
<<tool_names>>
You also can perform computations in the python code you generate.
Always provide a 'Thought:' and a 'Code:\n```py' sequence ending with '```<end_code>' sequence. You MUST provide at least the 'Code:' sequence to move forward.
Remember to not perform too many operations in a single code block! You should split the task into intermediate code blocks.
Print results at the end of each step to save the intermediate results. Then use final_answer() to return the final result.
Remember to make sure that variables you use are all defined.
Now Begin!
```
يتضمن موجه النظام:
- *مقدمة* تشرح كيف يجب أن يتصرف الوكيل والأدوات التي يجب عليه استخدامها.
- وصف لجميع الأدوات التي يتم تحديدها بواسطة رمز `<<tool_descriptions>>` الذي يتم استبداله ديناميكيًا في وقت التشغيل بالأدوات التي يحددها المستخدم أو يختارها.
- يأتي وصف الأداة من سمات الأداة، `name`، و`description`، و`inputs` و`output_type`، وقالب `jinja2` بسيط يمكنك تحسينه.
- شكل المخرج المتوقع.
يمكنك تحسين موجه النظام، على سبيل المثال، عن طريق إضافة شرح لتنسيق المخرجات.
للحصول على أقصى قدر من المرونة، يمكنك الكتابة فوق قالب موجه النظام بالكامل عن طريق تمرير موجه مخصص كمعامل إلى معلمة `system_prompt`.
```python
from transformers import ReactJsonAgent
from transformers.agents import PythonInterpreterTool
agent = ReactJsonAgent(tools=[PythonInterpreterTool()], system_prompt="{your_custom_prompt}")
```
> [!WARNING]
> يرجى التأكد من تحديد سلسلة `<<tool_descriptions>>` في مكان ما في `template` حتى يكون الوكيل على علم
بالأدوات المتاحة.
### فحص تشغيل الوكيل
فيما يلي بعض السمات المفيدة لفحص ما حدث بعد التشغيل:
- تخزن `agent.logs` سجلات مفصلة للوكيل. في كل خطوة من تشغيل الوكيل، يتم تخزين كل شيء في قاموس إلحاقه بـ `agent.logs`.
- تشغيل `agent.write_inner_memory_from_logs()` يخلق ذاكرة داخلية لسجلات الوكيل للنظام LLM لعرضها، كقائمة من رسائل الدردشة. تنتقل هذه الطريقة عبر كل خطوة من سجل الوكيل ولا تخزن سوى ما يهمها كرسالة: على سبيل المثال، سيحفظ موجه النظام والمهمة في رسائل منفصلة، ثم لكل خطوة سيخزن مخرج LLM كرسالة، ومخرج استدعاء الأداة كرسالة أخرى. استخدم هذا إذا كنت تريد عرضًا عامًا لما حدث - ولكن لن يتم نسخ كل سجل بواسطة هذه الطريقة.
## الأدوات
الأداة هي عبارة عن وظيفة أساسية يستخدمها الوكيل لتنفيذ مهمة محددة.
يمكنك على سبيل المثال التحقق من [`PythonInterpreterTool`]: لديه اسم ووصف ووصف للمدخلات ونوع للمخرج، وطريقة `__call__` التي تقوم بتنفيذ المهمة المطلوبة.
عند تهيئة الوكيل، يتم استخدام سمات الأداة لتوليد وصف للأداة يتم تضمينه في موجه النظام الخاص بالوكيل. يتيح هذا للوكيل معرفة الأدوات التي يمكنه استخدامها ولماذا.
### صندوق الأدوات الافتراضي
يأتي Transformers مع صندوق أدوات افتراضي لتمكين الوكلاء، والذي يمكنك إضافته إلى وكيلك عند التهيئة باستخدام معامل `add_base_tools = True`:
- **الإجابة على أسئلة المستند**: الإجابة على سؤال حول المستند (مثل ملف PDF) بتنسيق صورة ([Donut](./model_doc/donut))
- **الإجابة على أسئلة الصور**: الإجابة على سؤال حول صورة ([VILT](./model_doc/vilt))
- **التحدث إلى النص**: قم بتفريغ الكلام إلى نص ([Whisper](./model_doc/whisper))
- **النص إلى كلام**: تحويل النص إلى كلام ([SpeechT5](./model_doc/speecht5))
- **الترجمة**: ترجمة جملة معينة من لغة المصدر إلى لغة الهدف.
- **مفسر كود Python**: تشغيل كود Python الذي تم إنشاؤه بواسطة LLM في بيئة آمنة. لن يتم إضافة هذه الأداة إلى [`ReactJsonAgent`] إلا إذا استخدمت `add_base_tools=True`، نظرًا لأن الأدوات المستندة إلى التعليمات البرمجية يمكنها بالفعل تنفيذ كود Python
لا تترجم النصوص الخاصة ولا الأكواد البرمجية ولا الروابط ولا رموز HTML وCSS:
يمكنك استخدام أداة يدويًا عن طريق استدعاء دالة [`load_tool`] وتحديد مهمة لتنفيذها.
```python
from transformers import load_tool
tool = load_tool("text-to-speech")
audio = tool("This is a text to speech tool")
```
### إنشاء أداة جديدة
يمكنك إنشاء أداتك الخاصة لتغطية حالات الاستخدام التي لا تغطيها الأدوات الافتراضية من Hugging Face.
على سبيل المثال، دعنا نقوم بإنشاء أداة تعرض النموذج الأكثر تنزيلًا لمهمة معينة من Hub.
سوف نبدأ بالكود التالي.
```python
from huggingface_hub import list_models
task = "text-classification"
model = next(iter(list_models(filter=task, sort="downloads", direction=-1)))
print(model.id)
```
يمكن تحويل هذه الشيفرة إلى فئة ترث من الفئة العليا [`Tool`].
تحتاج الأداة المخصصة إلى:
- اسم `name`، والتي تمثل اسم الأداة نفسها. عادةً ما يصف الاسم وظيفتها. بما أن الكود يعيد النموذج الأكثر تنزيلًا لمهمة ما، فلنسمها `model_download_counter`.
- تستخدم خاصية `description` لملء موجه نظام الوكيل.
- خاصية `inputs`، والتي هي عبارة عن قاموس بمفاتيح "type" و"description". يحتوي على معلومات تساعد المفسر Python على اتخاذ خيارات مستنيرة بشأن المدخلات.
- خاصية `output_type`، والتي تحدد نوع المخرج.
- طريقة `forward` والتي تحتوي على الكود الذي سيتم تنفيذه للحصول على النتيجة النهائية.
```python
from transformers import Tool
from huggingface_hub import list_models
class HFModelDownloadsTool(Tool):
name = "model_download_counter"
description = (
"This is a tool that returns the most downloaded model of a given task on the Hugging Face Hub. "
"It returns the name of the checkpoint."
)
inputs = {
"task": {
"type": "text",
"description": "the task category (such as text-classification, depth-estimation, etc)",
}
}
output_type = "text"
def forward(self, task: str):
model = next(iter(list_models(filter=task, sort="downloads", direction=-1)))
return model.id
```
الآن بعد أن أصبحت فئة `HfModelDownloadsTool` المخصصة جاهزة، يمكنك حفظها في ملف باسم `model_downloads.py` واستيرادها للاستخدام.
```python
from model_downloads import HFModelDownloadsTool
tool = HFModelDownloadsTool()
```
يمكنك أيضًا مشاركة أداتك المخصصة في Hub عن طريق استدعاء [`~Tool.push_to_hub`] على الأداة. تأكد من أنك قمت بإنشاء مستودع لها على Hub وأنك تستخدم رمز وصول للقراءة.
```python
tool.push_to_hub("{your_username}/hf-model-downloads")
```
قم بتحميل الأداة باستخدام دالة [`~Tool.load_tool`] ومررها إلى معلمة `tools` في الوكيل الخاص بك.
```python
from transformers import load_tool, CodeAgent
model_download_tool = load_tool("m-ric/hf-model-downloads")
agent = CodeAgent(tools=[model_download_tool], llm_engine=llm_engine)
agent.run(
"Can you give me the name of the model that has the most downloads in the 'text-to-video' task on the Hugging Face Hub?"
)
```
ستحصل على ما يلي:
```text
======== New task ========
Can you give me the name of the model that has the most downloads in the 'text-to-video' task on the Hugging Face Hub?
==== Agent is executing the code below:
most_downloaded_model = model_download_counter(task="text-to-video")
print(f"The most downloaded model for the 'text-to-video' task is {most_downloaded_model}.")
====
```
والناتج:
`"النموذج الأكثر تنزيلًا لمهمة `text-to-video` هو ByteDance/AnimateDiff-Lightning."`
### إدارة صندوق أدوات الوكيل الخاص بك
إذا كنت قد قمت بتهيئة وكيل، فمن غير الملائم إعادة تهيئته من البداية لإضافة أداة جديدة ترغب في استخدامها. باستخدام مكتبة Transformers، يمكنك إدارة صندوق أدوات الوكيل بإضافة أو استبدال أداة موجودة.
دعنا نضيف الأداة `model_download_tool` إلى وكيل تم تهيئته مسبقًا باستخدام صندوق الأدوات الافتراضي.
```python
from transformers import CodeAgent
agent = CodeAgent(tools=[], llm_engine=llm_engine, add_base_tools=True)
agent.toolbox.add_tool(model_download_tool)
```
الآن يمكننا الاستفادة من الأداة الجديدة وأداة تحويل النص إلى كلام السابقة:
```python
agent.run(
"Can you read out loud the name of the model that has the most downloads in the 'text-to-video' task on the Hugging Face Hub and return the audio?"
)
```
| **Audio** |
|------------------------------------------------------------------------------------------------------------------------------------------------------|
| <audio controls><source src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/damo.wav" type="audio/wav"/> |
> [!WARNING]
> احترس عند إضافة أدوات إلى وكيل يعمل بالفعل لأنه يمكن أن يؤثر على اختيار الأداة لصالح أداتك أو اختيار أداة أخرى غير المحددة بالفعل.
استخدم طريقة `agent.toolbox.update_tool()` لاستبدال أداة موجودة في صندوق أدوات الوكيل.
هذا مفيد إذا كانت أداتك الجديدة بديلاً مباشرًا للأداة الموجودة لأن الوكيل يعرف بالفعل كيفية تنفيذ تلك المهمة المحددة.
تأكد فقط من اتباع الأداة الجديدة لنفس واجهة برمجة التطبيقات (API) للأداة المستبدلة أو قم بتكييف قالب موجه النظام لضمان تحديث جميع الأمثلة التي تستخدم الأداة المستبدلة.
### استخدام مجموعة من الأدوات
يمكنك الاستفادة من مجموعات الأدوات باستخدام كائن ToolCollection، مع تحديد مجموعة الأدوات التي تريد استخدامها.
ثم قم بتمريرها كقائمة لتهيئة الوكيل الخاص بك، وبدء استخدامها!
```py
from transformers import ToolCollection, ReactCodeAgent
image_tool_collection = ToolCollection(collection_slug="huggingface-tools/diffusion-tools-6630bb19a942c2306a2cdb6f")
agent = ReactCodeAgent(tools=[*image_tool_collection.tools], add_base_tools=True)
agent.run("Please draw me a picture of rivers and lakes.")
```
لتسريع البداية، يتم تحميل الأدوات فقط إذا استدعاها الوكيل.
ستحصل على هذه الصورة:
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/rivers_and_lakes.png" />
### استخدام gradio-tools
[gradio-tools](https://github.com/freddyaboulton/gradio-tools) هي مكتبة قوية تتيح استخدام Hugging
Face Spaces كأدوات. تدعم العديد من المساحات الموجودة بالإضافة إلى مساحات مخصصة.
تدعم مكتبة Transformers `gradio_tools` باستخدام طريقة [`Tool.from_gradio`] في الفئة. على سبيل المثال، دعنا نستخدم [`StableDiffusionPromptGeneratorTool`](https://github.com/freddyaboulton/gradio-tools/blob/main/gradio_tools/tools/prompt_generator.py) من مجموعة أدوات `gradio-tools` لتحسين المطالبات لإنشاء صور أفضل.
استورد وقم بتهيئة الأداة، ثم مررها إلى طريقة `Tool.from_gradio`:
```python
from gradio_tools import StableDiffusionPromptGeneratorTool
from transformers import Tool, load_tool, CodeAgent
gradio_prompt_generator_tool = StableDiffusionPromptGeneratorTool()
prompt_generator_tool = Tool.from_gradio(gradio_prompt_generator_tool)
```
الآن يمكنك استخدامه مثل أي أداة أخرى. على سبيل المثال، دعنا نحسن الموجه `a rabbit wearing a space suit`.
```python
image_generation_tool = load_tool('huggingface-tools/text-to-image')
agent = CodeAgent(tools=[prompt_generator_tool, image_generation_tool], llm_engine=llm_engine)
agent.run(
"Improve this prompt, then generate an image of it.", prompt='A rabbit wearing a space suit'
)
```
يستفيد النموذج بشكل كافٍ من الأداة:
```text
======== New task ========
Improve this prompt, then generate an image of it.
You have been provided with these initial arguments: {'prompt': 'A rabbit wearing a space suit'}.
==== Agent is executing the code below:
improved_prompt = StableDiffusionPromptGenerator(query=prompt)
while improved_prompt == "QUEUE_FULL":
improved_prompt = StableDiffusionPromptGenerator(query=prompt)
print(f"The improved prompt is {improved_prompt}.")
image = image_generator(prompt=improved_prompt)
====
```
قبل إنشاء الصورة أخيرًا:
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/rabbit_spacesuit_flux.webp" />
> [!WARNING]
> تتطلب gradio-tools إدخالات وإخراجات *نصية* حتى عند العمل مع طرائق مختلفة مثل كائنات الصور والصوت. الإدخالات والإخراجات الصورية والصوتية غير متوافقة حاليًا.
### استخدام أدوات LangChain
نحن نحب Langchain ونعتقد أنها تحتوي على مجموعة أدوات قوية للغاية.
لاستيراد أداة من LangChain، استخدم الطريقة `from_langchain()`.
فيما يلي كيفية استخدامها لإعادة إنشاء نتيجة البحث في المقدمة باستخدام أداة بحث الويب LangChain.
```python
from langchain.agents import load_tools
from transformers import Tool, ReactCodeAgent
search_tool = Tool.from_langchain(load_tools(["serpapi"])[0])
agent = ReactCodeAgent(tools=[search_tool])
agent.run("How many more blocks (also denoted as layers) in BERT base encoder than the encoder from the architecture proposed in Attention is All You Need?")
```
## واجهة Gradio
يمكنك الاستفادة من `gradio.Chatbot` لعرض أفكار الوكيل الخاص بك باستخدام `stream_to_gradio`، إليك مثال:
```py
import gradio as gr
from transformers import (
load_tool,
ReactCodeAgent,
HfEngine,
stream_to_gradio,
)
# Import tool from Hub
image_generation_tool = load_tool("m-ric/text-to-image")
llm_engine = HfEngine("meta-llama/Meta-Llama-3-70B-Instruct")
# Initialize the agent with the image generation tool
agent = ReactCodeAgent(tools=[image_generation_tool], llm_engine=llm_engine)
def interact_with_agent(task):
messages = []
messages.append(gr.ChatMessage(role="user", content=task))
yield messages
for msg in stream_to_gradio(agent, task):
messages.append(msg)
yield messages + [
gr.ChatMessage(role="assistant", content="⏳ Task not finished yet!")
]
yield messages
with gr.Blocks() as demo:
text_input = gr.Textbox(lines=1, label="Chat Message", value="Make me a picture of the Statue of Liberty.")
submit = gr.Button("Run illustrator agent!")
chatbot = gr.Chatbot(
label="Agent",
type="messages",
avatar_images=(
None,
"https://em-content.zobj.net/source/twitter/53/robot-face_1f916.png",
),
)
submit.click(interact_with_agent, [text_input], [chatbot])
if __name__ == "__main__":
demo.launch()
```

# Transformers Agents
<Tip warning={true}>
Transformers Agents ist eine experimentelle API, die jederzeit geändert werden kann. Die von den Agenten zurückgegebenen Ergebnisse
zurückgegeben werden, können variieren, da sich die APIs oder die zugrunde liegenden Modelle ändern können.
</Tip>
Transformers Version v4.29.0, die auf dem Konzept von *Tools* und *Agenten* aufbaut. Sie können damit spielen in
[dieses Colab](https://colab.research.google.com/drive/1c7MHD-T1forUPGcC_jlwsIptOzpG3hSj).
Kurz gesagt, es bietet eine API für natürliche Sprache auf der Grundlage von Transformers: Wir definieren eine Reihe von kuratierten Tools und entwerfen einen
Agenten, um natürliche Sprache zu interpretieren und diese Werkzeuge zu verwenden. Es ist von vornherein erweiterbar; wir haben einige relevante Tools kuratiert,
aber wir werden Ihnen zeigen, wie das System einfach erweitert werden kann, um jedes von der Community entwickelte Tool zu verwenden.
Beginnen wir mit einigen Beispielen dafür, was mit dieser neuen API erreicht werden kann. Sie ist besonders leistungsfähig, wenn es um

## Schnellstart
Bevor Sie `agent.run` verwenden können, müssen Sie einen Agenten instanziieren, der ein großes Sprachmodell (LLM) ist.
Wir bieten Unterstützung für openAI-Modelle sowie für OpenSource-Alternativen von BigCode und OpenAssistant. Die openAI
Modelle sind leistungsfähiger (erfordern aber einen openAI-API-Schlüssel, können also nicht kostenlos verwendet werden); Hugging Face
bietet kostenlosen Zugang zu Endpunkten für BigCode- und OpenAssistant-Modelle.
To start with, please install the `agents` extras in order to install all default dependencies.
```bash
pip install transformers[agents]
```
Um openAI-Modelle zu verwenden, instanziieren Sie einen [`OpenAiAgent`], nachdem Sie die `openai`-Abhängigkeit installiert haben:
```bash
pip install openai
```
```py
from transformers import OpenAiAgent
agent = OpenAiAgent(model="text-davinci-003", api_key="<your_api_key>")
```
Um BigCode oder OpenAssistant zu verwenden, melden Sie sich zunächst an, um Zugriff auf die Inference API zu erhalten:
```py
from huggingface_hub import login
login("<YOUR_TOKEN>")
```
Dann instanziieren Sie den Agenten
```py
from transformers import HfAgent
# Starcoder
agent = HfAgent("https://api-inference.huggingface.co/models/bigcode/starcoder")
# StarcoderBase
# agent = HfAgent("https://api-inference.huggingface.co/models/bigcode/starcoderbase")
# OpenAssistant
# agent = HfAgent(url_endpoint="https://api-inference.huggingface.co/models/OpenAssistant/oasst-sft-4-pythia-12b-epoch-3.5")
```
Dies geschieht mit der Inferenz-API, die Hugging Face derzeit kostenlos zur Verfügung stellt. Wenn Sie Ihren eigenen Inferenz
Endpunkt für dieses Modell (oder einen anderen) haben, können Sie die obige URL durch Ihren URL-Endpunkt ersetzen.
<Tip>
StarCoder und OpenAssistant sind kostenlos und leisten bei einfachen Aufgaben bewundernswert gute Arbeit. Allerdings halten die Kontrollpunkte
nicht, wenn es um komplexere Aufforderungen geht. Wenn Sie mit einem solchen Problem konfrontiert sind, empfehlen wir Ihnen, das OpenAI
Modell auszuprobieren, das zwar leider nicht quelloffen ist, aber zur Zeit eine bessere Leistung erbringt.
</Tip>
Sie sind jetzt startklar! Lassen Sie uns in die beiden APIs eintauchen, die Ihnen jetzt zur Verfügung stehen.
### Einzelne Ausführung (run)
Die Methode der einmaligen Ausführung ist die Verwendung der [`~Agent.run`] Methode des Agenten:
```py
agent.run("Draw me a picture of rivers and lakes.")
```
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/rivers_and_lakes.png" width=200>
Es wählt automatisch das (oder die) Werkzeug(e) aus, das (die) für die von Ihnen gewünschte Aufgabe geeignet ist (sind) und führt es (sie) entsprechend aus. Es
kann eine oder mehrere Aufgaben in der gleichen Anweisung ausführen (je komplexer Ihre Anweisung ist, desto wahrscheinlicher ist ein
der Agent scheitern).
```py
agent.run("Draw me a picture of the sea then transform the picture to add an island")
```
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/sea_and_island.png" width=200>
<br/>
Jede [`~Agent.run`] Operation ist unabhängig, so dass Sie sie mehrmals hintereinander mit unterschiedlichen Aufgaben ausführen können.
Beachten Sie, dass Ihr `Agent` nur ein großsprachiges Modell ist, so dass kleine Variationen in Ihrer Eingabeaufforderung völlig unterschiedliche Ergebnisse liefern können.
unterschiedliche Ergebnisse liefern. Es ist wichtig, dass Sie die Aufgabe, die Sie ausführen möchten, so genau wie möglich erklären. Wir gehen noch weiter ins Detail
wie man gute Prompts schreibt [hier](custom_tools#writing-good-user-inputs).
Wenn Sie einen Status über Ausführungszeiten hinweg beibehalten oder dem Agenten Nicht-Text-Objekte übergeben möchten, können Sie dies tun, indem Sie
Variablen, die der Agent verwenden soll. Sie könnten zum Beispiel das erste Bild von Flüssen und Seen erzeugen,
und das Modell bitten, dieses Bild zu aktualisieren und eine Insel hinzuzufügen, indem Sie Folgendes tun:
```python
picture = agent.run("Generate a picture of rivers and lakes.")
updated_picture = agent.run("Transform the image in `picture` to add an island to it.", picture=picture)
```
<Tip>
Dies kann hilfreich sein, wenn das Modell Ihre Anfrage nicht verstehen kann und die Werkzeuge verwechselt. Ein Beispiel wäre:
```py
agent.run("Draw me the picture of a capybara swimming in the sea")
```
Hier könnte das Modell auf zwei Arten interpretieren:
- Die Funktion `Text-zu-Bild` erzeugt ein Wasserschwein, das im Meer schwimmt.
- Oder Sie lassen das `Text-zu-Bild` ein Wasserschwein erzeugen und verwenden dann das Werkzeug `Bildtransformation`, um es im Meer schwimmen zu lassen.
Falls Sie das erste Szenario erzwingen möchten, können Sie dies tun, indem Sie die Eingabeaufforderung als Argument übergeben:
```py
agent.run("Draw me a picture of the `prompt`", prompt="a capybara swimming in the sea")
```
</Tip>
### Chat-basierte Ausführung (Chat)
Der Agent verfügt auch über einen Chat-basierten Ansatz, der die Methode [`~Agent.chat`] verwendet:
```py
agent.chat("Generate a picture of rivers and lakes")
```
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/rivers_and_lakes.png" width=200>
```py
agent.chat("Transform the picture so that there is a rock in there")
```
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/rivers_and_lakes_and_beaver.png" width=200>
<br/>
Dies ist ein interessanter Ansatz, wenn Sie den Zustand über Anweisungen hinweg beibehalten möchten. Er ist besser für Experimente geeignet,
eignet sich aber eher für einzelne Anweisungen als für komplexe Anweisungen (die die [`~Agent.run`]
Methode besser verarbeiten kann).
Diese Methode kann auch Argumente entgegennehmen, wenn Sie Nicht-Text-Typen oder bestimmte Aufforderungen übergeben möchten.
### ⚠️ Fernausführung
Zu Demonstrationszwecken und damit es mit allen Setups verwendet werden kann, haben wir Remote-Executors für mehrere
der Standard-Tools erstellt, auf die der Agent in dieser Version Zugriff hat. Diese werden erstellt mit
[inference endpoints](https://huggingface.co/inference-endpoints).
Wir haben diese vorerst deaktiviert, aber um zu sehen, wie Sie selbst Remote Executors Tools einrichten können,
empfehlen wir die Lektüre des [custom tool guide](./custom_tools).
### Was passiert hier? Was sind Tools und was sind Agenten?
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/diagram.png">
#### Agenten
Der "Agent" ist hier ein großes Sprachmodell, das wir auffordern, Zugang zu einem bestimmten Satz von Tools zu erhalten.
LLMs sind ziemlich gut darin, kleine Codeproben zu erzeugen. Diese API macht sich das zunutze, indem sie das
LLM ein kleines Codebeispiel gibt, das eine Aufgabe mit einer Reihe von Werkzeugen ausführt. Diese Aufforderung wird dann ergänzt durch die
Aufgabe, die Sie Ihrem Agenten geben, und die Beschreibung der Werkzeuge, die Sie ihm geben. Auf diese Weise erhält er Zugriff auf die Dokumentation der
Tools, insbesondere die erwarteten Eingaben und Ausgaben, und kann den entsprechenden Code generieren.
#### Tools
Tools sind sehr einfach: Sie bestehen aus einer einzigen Funktion mit einem Namen und einer Beschreibung. Wir verwenden dann die Beschreibungen dieser Tools
um den Agenten aufzufordern. Anhand der Eingabeaufforderung zeigen wir dem Agenten, wie er die Tools nutzen kann, um das zu tun, was in der
in der Abfrage angefordert wurde.
Dies geschieht mit brandneuen Tools und nicht mit Pipelines, denn der Agent schreibt besseren Code mit sehr atomaren Tools.
Pipelines sind stärker refaktorisiert und fassen oft mehrere Aufgaben in einer einzigen zusammen. Tools sind dafür gedacht, sich auf
eine einzige, sehr einfache Aufgabe konzentrieren.
#### Code-Ausführung?!
Dieser Code wird dann mit unserem kleinen Python-Interpreter auf den mit Ihren Tools übergebenen Eingaben ausgeführt.
Wir hören Sie schon schreien "Willkürliche Codeausführung!", aber lassen Sie uns erklären, warum das nicht der Fall ist.
Die einzigen Funktionen, die aufgerufen werden können, sind die von Ihnen zur Verfügung gestellten Tools und die Druckfunktion, so dass Sie bereits eingeschränkt sind
eingeschränkt, was ausgeführt werden kann. Sie sollten sicher sein, wenn es sich auf die Werkzeuge für das Umarmungsgesicht beschränkt.
Dann lassen wir keine Attributsuche oder Importe zu (die ohnehin nicht benötigt werden, um die
Inputs/Outputs an eine kleine Gruppe von Funktionen), so dass alle offensichtlichen Angriffe (und Sie müssten den LLM
dazu auffordern, sie auszugeben) kein Problem darstellen sollten. Wenn Sie auf Nummer sicher gehen wollen, können Sie die
run()-Methode mit dem zusätzlichen Argument return_code=True ausführen. In diesem Fall gibt der Agent nur den auszuführenden Code
zur Ausführung zurück und Sie können entscheiden, ob Sie ihn ausführen möchten oder nicht.
Die Ausführung bricht bei jeder Zeile ab, in der versucht wird, eine illegale Operation auszuführen, oder wenn ein regulärer Python-Fehler
mit dem vom Agenten generierten Code.
### Ein kuratierter Satz von Tools
Wir haben eine Reihe von Tools identifiziert, die solche Agenten unterstützen können. Hier ist eine aktualisierte Liste der Tools, die wir integriert haben
in `transformers` integriert haben:
- **Beantwortung von Fragen zu Dokumenten**: Beantworten Sie anhand eines Dokuments (z.B. PDF) im Bildformat eine Frage zu diesem Dokument ([Donut](./model_doc/donut))
- Beantworten von Textfragen**: Geben Sie einen langen Text und eine Frage an, beantworten Sie die Frage im Text ([Flan-T5](./model_doc/flan-t5))
- **Unbedingte Bildunterschriften**: Beschriften Sie das Bild! ([BLIP](./model_doc/blip))
- **Bildfragebeantwortung**: Beantworten Sie bei einem Bild eine Frage zu diesem Bild ([VILT](./model_doc/vilt))
- **Bildsegmentierung**: Geben Sie ein Bild und einen Prompt an und geben Sie die Segmentierungsmaske dieses Prompts aus ([CLIPSeg](./model_doc/clipseg))
- **Sprache in Text**: Geben Sie eine Audioaufnahme einer sprechenden Person an und transkribieren Sie die Sprache in Text ([Whisper](./model_doc/whisper))
- **Text in Sprache**: wandelt Text in Sprache um ([SpeechT5](./model_doc/speecht5))
- **Zero-Shot-Textklassifizierung**: Ermitteln Sie anhand eines Textes und einer Liste von Bezeichnungen, welcher Bezeichnung der Text am ehesten entspricht ([BART](./model_doc/bart))
- **Textzusammenfassung**: fassen Sie einen langen Text in einem oder wenigen Sätzen zusammen ([BART](./model_doc/bart))
- **Übersetzung**: Übersetzen des Textes in eine bestimmte Sprache ([NLLB](./model_doc/nllb))
Diese Tools sind in Transformatoren integriert und können auch manuell verwendet werden, zum Beispiel:
```py
from transformers import load_tool
tool = load_tool("text-to-speech")
audio = tool("This is a text to speech tool")
```
### Benutzerdefinierte Tools
Wir haben zwar eine Reihe von Tools identifiziert, sind aber der festen Überzeugung, dass der Hauptwert dieser Implementierung darin besteht
die Möglichkeit, benutzerdefinierte Tools schnell zu erstellen und weiterzugeben.
Indem Sie den Code eines Tools in einen Hugging Face Space oder ein Modell-Repository stellen, können Sie das Tool
direkt mit dem Agenten nutzen. Wir haben ein paar neue Funktionen hinzugefügt
**transformers-agnostic** Tools zur [`huggingface-tools` Organisation](https://huggingface.co/huggingface-tools) hinzugefügt:
- **Text-Downloader**: zum Herunterladen eines Textes von einer Web-URL
- **Text zu Bild**: erzeugt ein Bild nach einer Eingabeaufforderung und nutzt dabei stabile Diffusion
- **Bildtransformation**: verändert ein Bild anhand eines Ausgangsbildes und einer Eingabeaufforderung, unter Ausnutzung der stabilen pix2pix-Diffusion
- **Text zu Video**: Erzeugen eines kleinen Videos nach einer Eingabeaufforderung, unter Verwendung von damo-vilab
Das Text-zu-Bild-Tool, das wir von Anfang an verwendet haben, ist ein Remote-Tool, das sich in
[*huggingface-tools/text-to-image*](https://huggingface.co/spaces/huggingface-tools/text-to-image)! Wir werden
weiterhin solche Tools für diese und andere Organisationen veröffentlichen, um diese Implementierung weiter zu verbessern.
Die Agenten haben standardmäßig Zugriff auf die Tools, die sich auf [*huggingface-tools*](https://huggingface.co/huggingface-tools) befinden.
Wie Sie Ihre eigenen Tools schreiben und freigeben können und wie Sie jedes benutzerdefinierte Tool, das sich auf dem Hub befindet, nutzen können, erklären wir in [folgender Anleitung](custom_tools).
### Code-Erzeugung
Bisher haben wir gezeigt, wie Sie die Agenten nutzen können, um Aktionen für Sie durchzuführen. Der Agent generiert jedoch nur Code
den wir dann mit einem sehr eingeschränkten Python-Interpreter ausführen. Falls Sie den generierten Code in einer anderen Umgebung verwenden möchten
einer anderen Umgebung verwenden möchten, können Sie den Agenten auffordern, den Code zusammen mit einer Tooldefinition und genauen Importen zurückzugeben.
Zum Beispiel die folgende Anweisung
```python
agent.run("Draw me a picture of rivers and lakes", return_code=True)
```
gibt den folgenden Code zurück
```python
from transformers import load_tool
image_generator = load_tool("huggingface-tools/text-to-image")
image = image_generator(prompt="rivers and lakes")
```
die Sie dann selbst ändern und ausführen können.

# Accelerator selection
During distributed training, you can specify the number and order of accelerators (CUDA, XPU, MPS, HPU, etc.) to use. This can be useful when you have accelerators with different computing power and you want to use the faster accelerator first. Or you could only use a subset of the available accelerators. The selection process works for both [DistributedDataParallel](https://pytorch.org/docs/stable/generated/torch.nn.parallel.DistributedDataParallel.html) and [DataParallel](https://pytorch.org/docs/stable/generated/torch.nn.DataParallel.html). You don't need Accelerate or [DeepSpeed integration](./main_classes/deepspeed).
This guide will show you how to select the number of accelerators to use and the order to use them in.
## Number of accelerators
For example, if there are 4 accelerators and you only want to use the first 2, run the command below.
<hfoptions id="select-accelerator">
<hfoption id="torchrun">
Use the `--nproc_per_node` to select how many accelerators to use.
```bash
torchrun --nproc_per_node=2 trainer-program.py ...
```
</hfoption>
<hfoption id="Accelerate">
Use `--num_processes` to select how many accelerators to use.
```bash
accelerate launch --num_processes 2 trainer-program.py ...
```
</hfoption>
<hfoption id="DeepSpeed">
Use `--num_gpus` to select how many GPUs to use.
```bash
deepspeed --num_gpus 2 trainer-program.py ...
```
</hfoption>
</hfoptions>
## Order of accelerators
To select specific accelerators to use and their order, use the environment variable appropriate for your hardware. This is often set on the command line for each run, but can also be added to your `~/.bashrc` or other startup config file.
For example, if there are 4 accelerators (0, 1, 2, 3) and you only want to run accelerators 0 and 2:
<hfoptions id="accelerator-type">
<hfoption id="CUDA">
```bash
CUDA_VISIBLE_DEVICES=0,2 torchrun trainer-program.py ...
```
Only GPUs 0 and 2 are "visible" to PyTorch and are mapped to `cuda:0` and `cuda:1` respectively.
To reverse the order (use GPU 2 as `cuda:0` and GPU 0 as `cuda:1`):
```bash
CUDA_VISIBLE_DEVICES=2,0 torchrun trainer-program.py ...
```
To run without any GPUs:
```bash
CUDA_VISIBLE_DEVICES= python trainer-program.py ...
```
You can also control the order of CUDA devices using `CUDA_DEVICE_ORDER`:
- Order by PCIe bus ID (matches `nvidia-smi`):
```bash
export CUDA_DEVICE_ORDER=PCI_BUS_ID
```
- Order by compute capability (fastest first):
```bash
export CUDA_DEVICE_ORDER=FASTEST_FIRST
```
</hfoption>
<hfoption id="Intel XPU">
```bash
ZE_AFFINITY_MASK=0,2 torchrun trainer-program.py ...
```
Only XPUs 0 and 2 are "visible" to PyTorch and are mapped to `xpu:0` and `xpu:1` respectively.
To reverse the order (use XPU 2 as `xpu:0` and XPU 0 as `xpu:1`):
```bash
ZE_AFFINITY_MASK=2,0 torchrun trainer-program.py ...
```
You can also control the order of Intel XPUs with:
```bash
export ZE_ENABLE_PCI_ID_DEVICE_ORDER=1
```
For more information about device enumeration and sorting on Intel XPU, please refer to the [Level Zero](https://github.com/oneapi-src/level-zero/blob/master/README.md?plain=1#L87) documentation.
</hfoption>
</hfoptions>
> [!WARNING]
> Environment variables can be exported instead of being added to the command line. This is not recommended because it can be confusing if you forget how the environment variable was set up and you end up using the wrong accelerators. Instead, it is common practice to set the environment variable for a specific training run on the same command line.

# Agents
[[open-in-colab]]
An agent is a system where a large language model (LLM) can execute more complex tasks through *planning* and using *tools*.
- Planning helps a LLM reason its way through a task by breaking it down into smaller subtasks. For example, [`CodeAgent`] plans a series of actions to take and then generates Python code to execute all the actions at once.
Another planning method is by self-reflection and refinement of its previous actions to improve its performance. The [`ReactJsonAgent`] is an example of this type of planning, and it's based on the [ReAct](https://hf.co/papers/2210.03629) framework. This agent plans and executes actions one at a time based on the feedback it receives from each action.
- Tools give a LLM access to external functions or APIs that it can use to help it complete a task. For example, [gradio-tools](https://github.com/freddyaboulton/gradio-tools) gives a LLM access to any of the [Gradio](https://www.gradio.app/) apps available on Hugging Face [Spaces](https://hf.co/spaces). These apps can be used for a wide range of tasks such as image generation, video generation, audio transcription, and more.
To use agents in Transformers, make sure you have the extra `agents` dependencies installed.
```bash
!pip install transformers[agents]
```
Create an agent instance (refer to the [Agents](./main_classes/agent#agents) API for supported agents in Transformers) and a list of tools available for it to use, then [`~ReactAgent.run`] the agent on your task. The example below demonstrates how a ReAct agent reasons through a task.
```py
from transformers import ReactCodeAgent
agent = ReactCodeAgent(tools=[])
agent.run(
"How many more blocks (also denoted as layers) in BERT base encoder than the encoder from the architecture proposed in Attention is All You Need?",
)
```
```bash
======== New task ========
How many more blocks (also denoted as layers) in BERT base encoder than the encoder from the architecture proposed in Attention is All You Need?
==== Agent is executing the code below:
bert_layers = 12 # BERT base encoder has 12 layers
attention_layers = 6 # Encoder in Attention is All You Need has 6 layers
layer_diff = bert_layers - attention_layers
print("The difference in layers between BERT base encoder and Attention is All You Need is", layer_diff)
====
Print outputs:
The difference in layers between BERT base encoder and Attention is All You Need is 6
==== Agent is executing the code below:
final_answer("BERT base encoder has {} more layers than the encoder from Attention is All You Need.".format(layer_diff))
====
Print outputs:
>>> Final answer:
BERT base encoder has 6 more layers than the encoder from Attention is All You Need.
```
This guide will walk you through in more detail how to initialize an agent.
## LLM
An agent uses a LLM to plan and execute a task; it is the engine that powers the agent. To choose and build your own LLM engine, you need a method that:
1. the input uses the [chat template](./chat_templating) format, `List[Dict[str, str]]`, and it returns a string
2. the LLM stops generating outputs when it encounters the sequences in `stop_sequences`
```py
def llm_engine(messages, stop_sequences=["Task"]) -> str:
response = client.chat_completion(messages, stop=stop_sequences, max_tokens=1000)
answer = response.choices[0].message.content
return answer
```
Next, initialize an engine to load a model. To run an agent locally, create a [`TransformersEngine`] to load a preinitialized [`Pipeline`].
However, you could also leverage Hugging Face's powerful inference infrastructure, [Inference API](https://hf.co/docs/api-inference/index) or [Inference Endpoints](https://hf.co/docs/inference-endpoints/index), to run your model. This is useful for loading larger models that are typically required for agentic behavior. In this case, load the [`HfApiEngine`] to run the agent.
The agent requires a list of tools it can use to complete a task. If you aren't using any additional tools, pass an empty list. The default tools provided by Transformers are loaded automatically, but you can optionally set `add_base_tools=True` to explicitly enable them.
<hfoptions id="engine">
<hfoption id="TransformersEngine">
```py
from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline, TransformersEngine, CodeAgent
tokenizer = AutoTokenizer.from_pretrained("meta-llama/Llama-3.1-8B-Instruct")
model = AutoModelForCausalLM.from_pretrained("meta-llama/Llama-3.1-8B-Instruct").to("cuda")
pipeline = pipeline("text-generation", model=model, tokenizer=tokenizer)
llm_engine = TransformersEngine(pipeline)
agent = CodeAgent(tools=[], llm_engine=llm_engine)
agent.run(
"What causes bread to rise?",
)
```
</hfoption>
<hfoption id="HfApiEngine">
```py
from transformers import CodeAgent, HfApiEngine
llm_engine = HfApiEngine(model="meta-llama/Meta-Llama-3-70B-Instruct")
agent = CodeAgent(tools=[], llm_engine=llm_engine)
agent.run(
"Could you translate this sentence from French, say it out loud and return the audio.",
sentence="Où est la boulangerie la plus proche?",
)
```
</hfoption>
</hfoptions>
The agent supports [constrained generation](https://hf.co/docs/text-generation-inference/conceptual/guidance) for generating outputs according to a specific structure with the `grammar` parameter. The `grammar` parameter should be specified in the `llm_engine` method or you can set it when initializing an agent.
Lastly, an agent accepts additional inputs such as text and audio. In the [`HfApiEngine`] example above, the agent accepted a sentence to translate. But you could also pass a path to a local or remote file for the agent to access. The example below demonstrates how to pass a path to an audio file.
```py
from transformers import ReactCodeAgent
agent = ReactCodeAgent(tools=[], llm_engine=llm_engine)
agent.run("Why doesn't he know many people in New York?", audio="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/recording.mp3")
```
## System prompt
A system prompt describes how an agent should behave, a description of the available tools, and the expected output format.
Tools are defined by the `<<tool_descriptions>>` token which is dynamically replaced during runtime with the actual tool. The tool description is derived from the tool name, description, inputs, output type, and a Jinja2 template. Refer to the [Tools](./tools) guide for more information about how to describe tools.
The example below is the system prompt for [`ReactCodeAgent`].
```py
You will be given a task to solve as best you can.
You have access to the following tools:
<<tool_descriptions>>
To solve the task, you must plan forward to proceed in a series of steps, in a cycle of 'Thought:', 'Code:', and 'Observation:' sequences.
At each step, in the 'Thought:' sequence, you should first explain your reasoning towards solving the task, then the tools that you want to use.
Then in the 'Code:' sequence, you should write the code in simple Python. The code sequence must end with '/End code' sequence.
During each intermediate step, you can use 'print()' to save whatever important information you will then need.
These print outputs will then be available in the 'Observation:' field, for using this information as input for the next step.
In the end you have to return a final answer using the `final_answer` tool.
Here are a few examples using notional tools:
---
{examples}
Above example were using notional tools that might not exist for you. You only have access to those tools:
<<tool_names>>
You also can perform computations in the python code you generate.
Always provide a 'Thought:' and a 'Code:\n```py' sequence ending with '```<end_code>' sequence. You MUST provide at least the 'Code:' sequence to move forward.
Remember to not perform too many operations in a single code block! You should split the task into intermediate code blocks.
Print results at the end of each step to save the intermediate results. Then use final_answer() to return the final result.
Remember to make sure that variables you use are all defined.
Now Begin!
```
The system prompt can be tailored to the intended task. For example, you can add a better explanation of the output format or you can overwrite the system prompt template entirely with your own custom system prompt as shown below.
> [!WARNING]
> If you're writing a custom system prompt, make sure to include `<<tool_descriptions>>` in the template so the agent is aware of the available tools.
```py
from transformers import ReactJsonAgent
from transformers.agents import PythonInterpreterTool
agent = ReactJsonAgent(tools=[PythonInterpreterTool()], system_prompt="{your_custom_prompt}")
```
## Code execution
For safety, only the tools you provide (and the default Transformers tools) and the `print` function are executed. The interpreter doesn't allow importing modules that aren't on a safe list.
To import modules that aren't on the list, add them as a list to the `additional_authorized_imports` parameter when initializing an agent.
```py
from transformers import ReactCodeAgent
agent = ReactCodeAgent(tools=[], additional_authorized_imports=['requests', 'bs4'])
agent.run("Could you get me the title of the page at url 'https://huggingface.co/blog'?")
```
Code execution stops if a tool isn't on the safe list, it isn't authorized, or if the code generated by the agent returns a Python error.
> [!WARNING]
> A LLM can generate any arbitrary code that can be executed, so don't add any unsafe imports!
## Multi-agent
[Multi-agent](https://hf.co/papers/2308.08155) refers to multiple agents working together to solve a task. Performance is typically better because each agent is specialized for a particular subtask.
Multi-agents are created through a [`ManagedAgent`] class, where a *manager agent* oversees how other agents work together. The manager agent requires an agent and their name and description. These are added to the manager agents system prompt which lets it know how to call and use them.
The multi-agent example below creates a web search agent that is managed by another [`ReactCodeAgent`].
```py
from transformers.agents import ReactCodeAgent, HfApiEngine, DuckDuckGoSearchTool, ManagedAgent
llm_engine = HfApiEngine()
web_agent = ReactCodeAgent(tools=[DuckDuckGoSearchTool()], llm_engine=llm_engine)
managed_web_agent = ManagedAgent(
agent=web_agent,
name="web_search",
description="Runs web searches for you. Give it your query as an argument."
)
manager_agent = ReactCodeAgent(
tools=[], llm_engine=llm_engine, managed_agents=[managed_web_agent]
)
manager_agent.run("Who is the CEO of Hugging Face?")
```
## Gradio integration
[Gradio](https://www.gradio.app/) is a library for quickly creating and sharing machine learning apps. The [gradio.Chatbot](https://www.gradio.app/docs/gradio/chatbot) supports chatting with a Transformers agent with the [`stream_to_gradio`] function.
Load a tool and LLM with an agent, and then create a Gradio app. The key is to use [`stream_to_gradio`] to stream the agents messages and display how it's reasoning through a task.
```py
import gradio as gr
from transformers import (
load_tool,
ReactCodeAgent,
HfApiEngine,
stream_to_gradio,
)
# Import tool from Hub
image_generation_tool = load_tool("m-ric/text-to-image")
llm_engine = HfApiEngine("meta-llama/Meta-Llama-3-70B-Instruct")
# Initialize the agent with the image generation tool
agent = ReactCodeAgent(tools=[image_generation_tool], llm_engine=llm_engine)
def interact_with_agent(task):
messages = []
messages.append(gr.ChatMessage(role="user", content=task))
yield messages
for msg in stream_to_gradio(agent, task):
messages.append(msg)
yield messages + [
gr.ChatMessage(role="assistant", content="⏳ Task not finished yet!")
]
yield messages
with gr.Blocks() as demo:
text_input = gr.Textbox(lines=1, label="Chat Message", value="Make me a picture of the Statue of Liberty.")
submit = gr.Button("Run illustrator agent!")
chatbot = gr.Chatbot(
label="Agent",
type="messages",
avatar_images=(
None,
"https://em-content.zobj.net/source/twitter/53/robot-face_1f916.png",
),
)
submit.click(interact_with_agent, [text_input], [chatbot])
if __name__ == "__main__":
demo.launch()
```
## Troubleshoot
For a better idea of what is happening when you call an agent, it is always a good idea to check the system prompt template first.
```py
print(agent.system_prompt_template)
```
If the agent is behaving unexpectedly, remember to explain the task you want to perform as clearly as possible. Every [`~Agent.run`] is different and minor variations in your system prompt may yield completely different results.
To find out what happened after a run, check the following agent attributes.
- `agent.logs` stores the finegrained agent logs. At every step of the agents run, everything is stored in a dictionary and appended to `agent.logs`.
- `agent.write_inner_memory_from_logs` only stores a high-level overview of the agents run. For example, at each step, it stores the LLM output as a message and the tool call output as a separate message. Not every detail from a step is transcripted by `write_inner_memory_from_logs`.

## Attention Mask Interface
Having a new attention function may mean that you need a new format of attention mask to decide what key and value tokens
the query tokens should attend to. This is now possible with the `AttentionMaskInterface`! It works in the same way as
the `AttentionInterface`:
```python
from transformers import AttentionMaskInterface
from transformers.masking_utils import sdpa_mask
import torch
def my_new_sdpa_mask(*args, **kwargs):
print("I just entered the attention mask computation")
return sdpa_mask(*args, **kwargs)
AttentionMaskInterface.register("my_new_sdpa_mask", my_new_sdpa_mask)
```
The reason you have to register it is because we need to automatically correct your mask format based on the attention implementation (for example, flex attention uses a BlockMask format, while sdpa uses a 4D tensor).
By default, if you do not register an attention mask function along with your attention function, mask creation will be skipped
and `attention_mask=None` will be passed along to the Attention layers.
The default signature of the attention mask functions is the following:
```python
def custom_attention_mask(
batch_size: int, # required arg
cache_position: torch.Tensor, # required arg
kv_length: int, # required arg
kv_offset: int = 0, # required arg
mask_function: Callable = causal_mask_function, # required arg
attention_mask: Optional[torch.Tensor] = None, # required arg
**kwargs, # a few additional args may be passed as kwargs, especially the model's config is always passed
) -> Optional[torch.Tensor]:
```
It mostly works thanks to the `mask_function`, which is a `Callable` in the form of [torch's mask_mod functions](https://pytorch.org/blog/flexattention/), taking 4 indices as input and returning a boolean to indicate if this position should take part in the attention computation.
If you cannot use the `mask_function` to create your mask for some reason, you can try to work around it by doing something similar to our [torch export workaround](https://github.com/huggingface/transformers/blob/main/src/transformers/integrations/executorch.py).
```

# Utilizing the @auto_docstring Decorator
The `@auto_docstring` decorator in the Hugging Face Transformers library helps generate docstrings for model classes and their methods, which will be used to build the documentation for the library. It aims to improve consistency and reduce boilerplate by automatically including standard argument descriptions and allowing for targeted overrides and additions.
---
## 📜 How it Works
The `@auto_docstring` decorator constructs docstrings by:
1. **Signature Inspection:** It inspects the signature (arguments, types, defaults) of the decorated class's `__init__` method or the decorated function.
2. **Centralized Docstring Fetching:** It retrieves predefined docstrings for common arguments (e.g., `input_ids`, `attention_mask`) from internal library sources (like `ModelArgs` or `ImageProcessorArgs` in `utils/args_doc.py`).
3. **Overriding or Adding Arguments Descriptions:**
* **Direct Docstring Block:** It incorporates custom docstring content from an `r""" """` (or `""" """`) block below the method signature or within the `__init__` docstring. This is for documenting new arguments or overriding standard descriptions.
* **Decorator Arguments (`custom_args`):** A `custom_args` docstring block can be passed to the decorator to provide docstrings for specific arguments directly in the decorator call. This can be used to define the docstring block for new arguments once if they are repeated in multiple places in the modeling file.
4. **Adding Classes and Functions Introduction:**
* **`custom_intro` argument:** Allows prepending a custom introductory paragraph to a class or function docstring.
* **Automatic Introduction Generation:** For model classes with standard naming patterns (like `ModelForCausalLM`) or belonging to a pipeline, the decorator automatically generates an appropriate introductory paragraph using `ClassDocstring` in `utils/args_doc.py` as the source.
5. **Templating:** The decorator uses a templating system, allowing predefined docstrings to include dynamic information deduced from the `auto_modules` of the library, such as `{{processor_class}}` or `{{config_class}}`.
6. **Deducing Relevant Examples:** The decorator attempts to find appropriate usage examples based on the model's task or pipeline compatibility. It extracts checkpoint information from the model's configuration class to provide concrete examples with real model identifiers.
7. **Adding Return Value Documentation:** For methods like `forward`, the decorator can automatically generate the "Returns" section based on the method's return type annotation. For example, for a method returning a `ModelOutput` subclass, it will extracts field descriptions from that class's docstring to create a comprehensive return value description. A custom `Returns` section can also be manually specified in the function docstring block.
8. **Unrolling Kwargs Typed With Unpack Operator:** For specific methods (defined in `UNROLL_KWARGS_METHODS`) or classes (defined in `UNROLL_KWARGS_CLASSES`), the decorator processes `**kwargs` parameters that are typed with `Unpack[KwargsTypedDict]`. It extracts the documentation from the TypedDict and adds each parameter to the function's docstring. Currently, this functionality is only supported for `FastImageProcessorKwargs`.
---
## 🚀 How to Use @auto_docstring
### 1. Importing the Decorator
Import the decorator into your modeling file:
```python
from ...utils import auto_docstring
```
### 2. Applying to Classes
Place `@auto_docstring` directly above the class definition. It uses the `__init__` method's signature and its docstring for parameter descriptions.
```python
from transformers.modeling_utils import PreTrainedModel
from ...utils import auto_docstring
@auto_docstring
class MyAwesomeModel(PreTrainedModel):
def __init__(self, config, custom_parameter: int = 10, another_custom_arg: str = "default"):
r"""
custom_parameter (`int`, *optional*, defaults to 10):
Description of the custom_parameter for MyAwesomeModel.
another_custom_arg (`str`, *optional*, defaults to "default"):
Documentation for another unique argument.
"""
super().__init__(config)
self.custom_parameter = custom_parameter
self.another_custom_arg = another_custom_arg
# ... rest of your init
# ... other methods
```
#### Advanced Class Decoration:
Arguments can be passed directly to `@auto_docstring` for more control:
```python
@auto_docstring(
custom_intro="""This model performs specific synergistic operations.
It builds upon the standard Transformer architecture with unique modifications.""",
custom_args="""
custom_parameter (`type`, *optional*, defaults to `default_value`):
A concise description for custom_parameter if not defined or overriding the description in `args_doc.py`.
internal_helper_arg (`type`, *optional*, defaults to `default_value`):
A concise description for internal_helper_arg if not defined or overriding the description in `args_doc.py`.
"""
)
class MySpecialModel(PreTrainedModel):
def __init__(self, config: ConfigType, custom_parameter: "type" = "default_value", internal_helper_arg=None):
# ...
```
Or:
```python
@auto_docstring(
custom_intro="""This model performs specific synergistic operations.
It builds upon the standard Transformer architecture with unique modifications.""",
)
class MySpecialModel(PreTrainedModel):
def __init__(self, config: ConfigType, custom_parameter: "type" = "default_value", internal_helper_arg=None):
r"""
custom_parameter (`type`, *optional*, defaults to `default_value`):
A concise description for custom_parameter if not defined or overriding the description in `args_doc.py`.
internal_helper_arg (`type`, *optional*, defaults to `default_value`):
A concise description for internal_helper_arg if not defined or overriding the description in `args_doc.py`.
"""
# ...
```
### 3. Applying to Functions (e.g., `forward` method)
Apply the decorator above method definitions, such as the `forward` method.
```python
@auto_docstring
def forward(
self,
input_ids: Optional[torch.Tensor] = None,
attention_mask: Optional[torch.Tensor] = None,
new_custom_argument: Optional[torch.Tensor] = None,
arg_documented_in_args_doc: Optional[torch.Tensor] = None,
# ... other arguments
) -> Union[Tuple, ModelOutput]: # The description of the return value will automatically be generated from the ModelOutput class docstring.
r"""
new_custom_argument (`torch.Tensor`, *optional*):
Description of this new custom argument and its expected shape or type.
"""
# ...
```
#### Advanced Function Decoration:
Arguments can be passed directly to `@auto_docstring` for more control. `Returns` and `Examples` sections can also be manually specified:
```python
MODEL_COMMON_CUSTOM_ARGS = r"""
common_arg_1 (`torch.Tensor`, *optional*, defaults to `default_value`):
Description of common_arg_1
common_arg_2 (`torch.Tensor`, *optional*, defaults to `default_value`):
Description of common_arg_2
...
"""
class MyModel(PreTrainedModel):
# ...
@auto_docstring(
custom_intro="""
This is a custom introduction for the function.
"""
custom_args=MODEL_COMMON_CUSTOM_ARGS
)
def forward(
self,
input_ids: Optional[torch.Tensor] = None,
attention_mask: Optional[torch.Tensor] = None,
common_arg_1: Optional[torch.Tensor] = None,
common_arg_2: Optional[torch.Tensor] = None,
#...
function_specific_argument: Optional[torch.Tensor] = None,
# ... other arguments
) -> torch.Tensor:
r"""
function_specific_argument (`torch.Tensor`, *optional*):
Description of an argument specific to this function
Returns:
`torch.Tensor`: For a function returning a generic type, a custom "Returns" section can be specified.
Example:
(To override the default example with a custom one or to add an example for a model class that does not have a pipeline)
```python
...
```
"""
# ...
```
---
### ✍️ Documenting Arguments: Approach & Priority
1. **Standard Arguments (e.g., `input_ids`, `attention_mask`, `pixel_values`, `encoder_hidden_states` etc.):**
* `@auto_docstring` retrieves descriptions from a central source. Do not redefine these locally if their description and shape are the same as in `args_doc.py`.
2. **New or Custom Arguments:**
* **Primary Method:** Document these within an `r""" """` docstring block following the signature (for functions) or in the `__init__` method's docstring (for class parameters).
* **Format:**
```
argument_name (`type`, *optional*, defaults to `X`):
Description of the argument.
Explain its purpose, expected shape/type if complex, and default behavior.
This can span multiple lines.
```
* Include `type` in backticks.
* Add "*optional*" if the argument is not required (has a default value).
* Add "defaults to `X`" if it has a default value (no need to specify "defaults to `None`" if the default value is `None`).
3. **Overriding Standard Arguments:**
* If a standard argument behaves differently (e.g., different expected shape, model-specific behavior), provide its complete description in the local `r""" """` docstring. This local definition takes precedence.
* The `labels` argument is often customized per model and typically requires a specific docstring.
4. **Using Decorator Arguments for Overrides or New Arguments (`custom_args`):**
* New or custom arguments docstrings can also be passed to `@auto_docstring` as a `custom_args` argument. This can be used to define the docstring block for new arguments once if they are repeated in multiple places in the modeling file.

### Usage with [modular files](./modular_transformers)
When working with modular files, follow these guidelines for applying the `@auto_docstring` decorator:
- **For standalone models in modular files:**
Apply the `@auto_docstring` decorator just as you would in regular modeling files.
- **For models inheriting from other library models:**
- When inheriting from a parent model, decorators (including `@auto_docstring`) are automatically carried over to the generated modeling file without needing to add them in your modular file.
- If you need to modify the `@auto_docstring` behavior, apply the customized decorator in your modular file, making sure to *include all other decorators* that were present on the original function/class.
> **Warning**: When overriding any decorator in a modular file, you must include ALL decorators that were applied to that function/class in the parent model. If you only override some decorators, the others won't be included in the generated modeling file.
**Note**: The `check_auto_docstrings` tool doesn't check modular files directly, but it will check (and modify when using `--fix_and_overwrite`) the generated modeling files. If issues are found in the generated files, you'll need to update your modular files accordingly.
---
## ✅ Checking Your Docstrings with `check_auto_docstrings`
The library includes a utility script to validate docstrings. This check is typically run during Continuous Integration (CI).
#### What it Checks:
* **Decorator Presence:** Ensures `@auto_docstring` is applied to relevant model classes and public methods. (TODO)
* **Argument Completeness & Consistency:**
* Flags arguments in the signature that are not known standard arguments and lack a local description.
* Ensures documented arguments exist in the signature. (TODO)
* Verifies that types and default values in the docstring match the signature. (TODO)
* **Placeholder Detection:** Reminds you to complete placeholders like `<fill_type>` or `<fill_docstring>`.
* **Formatting:** Adherence to the expected docstring style.
#### Running the Check Locally:
Run this check locally before committing. The common command is:
```bash
make fix-copies
```
Alternatively, to only perform docstrings and auto-docstring checks, you can use:
```bash
python utils/check_docstrings.py # to only check files included in the diff without fixing them
# Or: python utils/check_docstrings.py --fix_and_overwrite # to fix and overwrite the files in the diff
# Or: python utils/check_docstrings.py --fix_and_overwrite --check_all # to fix and overwrite all files
```
#### Workflow with the Checker:
1. Add `@auto_docstring(...)` to the class or method.
2. For new, custom, or overridden arguments, add descriptions in an `r""" """` block.
3. Run `make fix-copies` (or the `check_docstrings.py` utility).
* For unrecognized arguments lacking documentation, the utility will create placeholder entries.
4. Manually edit these placeholders with accurate types and descriptions.
5. Re-run the check to ensure all issues are resolved.
---
## 🔑 Key Takeaways & Best Practices
* Use `@auto_docstring` for new PyTorch model classes (`PreTrainedModel` subclasses) and their primary for methods (e.g., `forward`, `get_text_features` etc.).
* For classes, the `__init__` method's docstring is the main source for parameter descriptions when using `@auto_docstring` on the class.
* Rely on standard docstrings; do not redefine common arguments unless their behavior is different in your specific model.
* Document new or custom arguments clearly.
* Run `check_docstrings` locally and iteratively.
By following these guidelines, you help maintain consistent and informative documentation for the Hugging Face Transformers library 🤗.

# Caching
Imagine you're having a conversation with someone, and instead of remembering what they previously said, they have to start from scratch every time you respond. This would be slow and inefficient, right?
Imagine youre having a conversation with someone, and instead of remembering what they previously said, they have to start from scratch every time you respond. This would be slow and inefficient, right?
You can extend this analogy to transformer models. Autoregressive model generation can be slow because it makes a prediction one token at a time. Each new prediction is dependent on all the previous context.

> [!WARNING]
> Caching should only be used for **inference**. It may cause unexpected errors if it's enabled during training.
To better understand how and why caching works, let's take a closer look at the structure of the attention matrices.
## Attention matrices
The **scaled dot-product attention** is calculated as shown below for a batch of size `b`, number of attention heads `h`, sequence length so far `T`, and dimension per attention head `d_head`.
$$
\text{Attention}(Q, K, V) = \text{softmax}\left( \frac{Q K^\top}{\sqrt{d_{\text{head}}}} \times \text{mask} \right) V
$$
The query (`Q`), key (`K`), and value (`V`) matrices are projections from the input embeddings of shape `(b, h, T, d_head)`.
For causal attention, the mask prevents the model from attending to future tokens. Once a token is processed, its representation never changes with respect to future tokens, which means \\( K_{\text{past}} \\) and \\( V_{\text{past}} \\) can be cached and reused to compute the last token's representation.
$$
\text{Attention}(q_t, [\underbrace{k_1, k_2, \dots, k_{t-1}}_{\text{cached}}, k_{t}], [\underbrace{v_1, v_2, \dots, v_{t-1}}_{\text{cached}}, v_{t}])
$$
At inference time, you only need the last token's query to compute the representation \\( x_t \\) that predicts the next token \\( t+1 \\). At each step, the new key and value vectors are **stored** in the cache and **appended** to the past keys and values.
$$
K_{\text{cache}} \leftarrow \text{concat}(K_{\text{past}}, k_t), \quad V_{\text{cache}} \leftarrow \text{concat}(V_{\text{past}}, v_t)
$$
Attention is calculated independently in each layer of the model, and caching is done on a per-layer basis.
Refer to the table below to compare how caching improves efficiency.
| without caching | with caching |
|---|---|
| for each step, recompute all previous `K` and `V` | for each step, only compute current `K` and `V`
| attention cost per step is **quadratic** with sequence length | attention cost per step is **linear** with sequence length (memory grows linearly, but compute/token remains low) |
## Cache class
A basic KV cache interface takes a key and value tensor for the current token and returns the updated `K` and `V` tensors. This is internally managed by a model's `forward` method.
```py
new_K, new_V = cache.update(k_t, v_t, layer_idx)
attn_output = attn_layer_idx_fn(q_t, new_K, new_V)
```
When you use Transformers' [`Cache`] class, the self-attention module performs several critical steps to integrate past and present information.
1. The attention module concatenates current kv pairs with past kv pairs stored in the cache. This creates attentions weights with the shape `(new_tokens_length, past_kv_length + new_tokens_length)`. The current and past kv pairs are essentially combined to compute the attention scores, ensuring a model is aware of previous context and the current input.
@ -80,27 +39,6 @@ When you use Transformers' [`Cache`] class, the self-attention module performs s
3. It is also important to be aware of the `cache_position`. This is important if you want to reuse a prefilled [`Cache`] with the `forward` method because you have to pass a valid `cache_position` value. This indicates the input positions in a sequence. `cache_position` is unaffected by padding, and it always adds one more position for each token. For example, if a kv cache contains 10 tokens - regardless of pad tokens - the cache position for the next token should be `torch.tensor([10])`.
## Cache storage implementation
The actual storage of key-value pairs varies between cache implementations. As an example, consider the [`DynamicCache`].
In [`DynamicCache`], the key-value pairs are stored as two lists of tensors. Each tensor in the lists have the shape `[batch_size, num_heads, seq_len, head_dim]`.
- `key_cache`: A list of tensors, one for each layer.
- `value_cache`: A list of tensors, one for each layer.
When new tokens are processed:
1. For each layer, the new key and value states are concatenated with the existing cache.
```py
self.key_cache[layer_idx] = torch.cat([self.key_cache[layer_idx], key_states], dim=-2)
self.value_cache[layer_idx] = torch.cat([self.value_cache[layer_idx], value_states], dim=-2)
```
2. The cache grows dynamically as more tokens are processed. The sequence length dimension (`seq_len`) increases with each new token.
3. The cache maintains a count of seen tokens through `self._seen_tokens`. This is updated when the first layer processes a new token.
The example below demonstrates how to create a generation loop with [`DynamicCache`]. As discussed, the attention mask is a concatenation of past and current token values and `1` is added to the cache position for the next token.
```py

print(tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0])
"[INST] Hello, what's your name. [/INST] Hello! My name is LLaMA,"
```
## Legacy cache format
Before the [`Cache`] class, the cache used to be stored as a tuple of tuples of tensors. This format is dynamic because it grows as text is generated, similar to [`DynamicCache`].
The legacy format is essentially the same data structure but organized differently.
- It's a tuple of tuples, where each inner tuple contains the key and value tensors for a layer.
- The tensors have the same shape `[batch_size, num_heads, seq_len, head_dim]`.
- The format is less flexible and doesn't support features like quantization or offloading.
Before the [`Cache`] class, the cache used to be stored as a tuple of tuples of tensors. This format has is dynamic because it grows as text is generated, similar to [`DynamicCache`].
If your project depends on this legacy format, you can convert between [`DynamicCache`] and a tuple of tuples as shown below with the [`~DynamicCache.from_legacy_cache`] and [`DynamicCache.to_legacy_cache`] functions. This is helpful if you have custom logic for manipulating a cache in a specific format.

Some models don't sample frames *uniformly* and require more complex logic to determine which frames to use. For example, the model may have an *adaptive frame selection* or if the model prioritizes *key moments* in a video rather than evenly spaced frames.
If a model has a different sampling strategy, you can write a function that customizes frame selection. The function should include the following requirements.
- Use the `sample_indices_fn` parameter to pass a callable function for sampling.
- If provided, this function *overrides* the standard `num_frames` and `fps` parameters.
- The function receives all the parameters passed to `load_video` and must return valid frame indices to sample from.

This guide will help you understand the different decoding strategies available in Transformers and how and when to use them.
## Basic decoding methods
## Greedy search
These are well established decoding methods, and should be your starting point for text generation tasks.
Greedy search is the default decoding strategy. It selects the next most likely token at each step. Unless specified in [`GenerationConfig`], this strategy generates a maximum of 20 tokens.

Greedy search works well for tasks with relatively short outputs where creativity is not a priority. However, it breaks down when generating longer sequences because it begins to repeat itself.

### Sampling
## Contrastive search
Sampling, or multinomial sampling, randomly selects a token based on the probability distribution over the entire model's vocabulary (as opposed to the most likely token, as in greedy search). This means every token with a non-zero probability has a chance to be selected. Sampling strategies reduce repetition and can generate more creative and diverse outputs.
[Contrastive search](https://huggingface.co/papers/2202.06417) is a decoding strategy that aims to reduce repetition even while generating longer sequences. This strategy compares how similar a generated token is against previous tokens, and if they're more similar, a penalty is applied.
Enable multinomial sampling with `do_sample=True` and `num_beams=1`.
Enable contrastive search with the `penalty_alpha` and `top_k` parameters. The `penalty_alpha` manages the penalty applied and `top_k` is the number of most likely tokens to return.

### Beam search
## Beam search
Beam search keeps track of several generated sequences (beams) at each time step. After a certain number of steps, it selects the sequence with the highest *overall* probability. Unlike greedy search, this strategy can "look ahead" and pick a sequence with a higher probability overall even if the initial tokens have a lower probability. It is best suited for input-grounded tasks, like describing an image or speech recognition. You can also use `do_sample=True` with beam search to sample at each step, but beam search will still greedily prune out low probability sequences between steps.

## Advanced decoding methods
## Diverse beam search
Advanced decoding methods aim at either tackling specific generation quality issues (e.g. repetition) or at improving the generation throughput in certain situations. These techniques are more complex, and may not work correctly with all models.
[Diverse beam search](https://hf.co/papers/1610.02424) is a variant of beam search that produces more diverse output candidates to choose from. This strategy measures the dissimilarity of sequences and a penalty is applied if sequences are too similar. To avoid high computation costs, the number of beams is divided into groups.
### Speculative decoding
Enable diverse beam search with the `num_beams`, `num_beam_groups` and `diversity_penalty` parameters (the `num_beams` parameter should be divisible by `num_beam_groups`).
```py
import torch

The main model verifies the candidate tokens in a single `forward` pass, which speeds up the decoding process overall. This method is especially useful for LLMs where it can be more costly and slower to generate tokens. Refer to the [speculative decoding](./llm_optims#speculative-decoding) guide to learn more.

## Custom decoding methods
Custom decoding methods enable specialized generation behavior such as the following:
- have the model continue thinking if it is uncertain;
- roll back generation if the model gets stuck;
- handle special tokens with custom logic;
- enhanced input preparation for advanced models;
We enable custom decoding methods through model repositories, assuming a specific model tag and file structure (see subsection below). This feature is an extension of [custom modeling code](./models.md#custom-models) and, like such, requires setting `trust_remote_code=True`.
If a model repository holds a custom decoding method, the easiest way to try it out is to load the model and generate with it:
```py
from transformers import AutoModelForCausalLM, AutoTokenizer
# `transformers-community/custom_generate_example` holds a copy of `Qwen/Qwen2.5-0.5B-Instruct`, but
# with custom generation code -> calling `generate` uses the custom decoding method!
tokenizer = AutoTokenizer.from_pretrained("transformers-community/custom_generate_example")
model = AutoModelForCausalLM.from_pretrained(
"transformers-community/custom_generate_example", device_map="auto", trust_remote_code=True
)
inputs = tokenizer(["The quick brown"], return_tensors="pt").to(model.device)
# The custom decoding method is a minimal greedy decoding implementation. It also prints a custom message at run time.
gen_out = model.generate(**inputs)
# you should now see its custom message, "✨ using a custom generation method ✨"
print(tokenizer.batch_decode(gen_out, skip_special_tokens=True))
'The quick brown fox jumps over a lazy dog, and the dog is a type of animal. Is'
```
Model repositories with custom decoding methods have a special property: their decoding method can be loaded from **any** model through [`~GenerationMixin.generate`]'s `custom_generate` argument. This means anyone can create and share their custom generation method to potentially work with any Transformers model, without requiring users to install additional Python packages.
```py
from transformers import AutoModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("Qwen/Qwen2.5-0.5B-Instruct")
model = AutoModelForCausalLM.from_pretrained("Qwen/Qwen2.5-0.5B-Instruct", device_map="auto")
inputs = tokenizer(["The quick brown"], return_tensors="pt").to(model.device)
# `custom_generate` replaces the original `generate` by the custom decoding method defined in
# `transformers-community/custom_generate_example`
gen_out = model.generate(**inputs, custom_generate="transformers-community/custom_generate_example", trust_remote_code=True)
print(tokenizer.batch_decode(gen_out, skip_special_tokens=True)[0])
'The quick brown fox jumps over a lazy dog, and the dog is a type of animal. Is'
```
You should read the `README.md` file of the repository containing the custom generation strategy to see what the new arguments and output type differences are, if they exist. Otherwise, you can assume it works like the base [`~GenerationMixin.generate`] method.
> [!TIP]
> You can find all custom decoding methods by [searching for their custom tag.](https://huggingface.co/models?other=custom_generate), `custom_generate`
Consider the Hub repository [transformers-community/custom_generate_example](https://huggingface.co/transformers-community/custom_generate_example) as an example. The `README.md` states that it has an additional input argument, `left_padding`, which adds a number of padding tokens before the prompt.
```py
gen_out = model.generate(
**inputs, custom_generate="transformers-community/custom_generate_example", trust_remote_code=True, left_padding=5
)
print(tokenizer.batch_decode(gen_out)[0])
'<|endoftext|><|endoftext|><|endoftext|><|endoftext|><|endoftext|>The quick brown fox jumps over the lazy dog.\n\nThe sentence "The quick'
```
If the custom method has pinned Python requirements that your environment doesn't meet, you'll get an exception about missing requirements. For instance, [transformers-community/custom_generate_bad_requirements](https://huggingface.co/transformers-community/custom_generate_bad_requirements) has an impossible set of requirements defined in its `custom_generate/requirements.txt` file, and you'll see the error message below if you try to run it.
```
ImportError: Missing requirements in your local environment for `transformers-community/custom_generate_bad_requirements`:
foo (installed: None)
bar==0.0.0 (installed: None)
torch>=99.0 (installed: 2.6.0)
```
Updating your Python requirements accordingly will remove this error message.
### Creating a custom decoding method
To create a new decoding method, you need to create a new [**Model**](https://huggingface.co/new) repository and push a few files into it.
1. The model you've designed your decoding method with.
2. `custom_generate/generate.py`, which contains all the logic for your custom decoding method.
3. `custom_generate/requirements.txt`, used to optionally add new Python requirements and/or lock specific versions to correctly use your method.
4. `README.md`, where you should add the `custom_generate` tag and document any new arguments or output type differences of your custom method here.
After you've added all required files, your repository should look like this
```
your_repo/
├── README.md # include the 'custom_generate' tag
├── config.json
├── ...
└── custom_generate/
├── generate.py
└── requirements.txt
```
#### Adding the base model
The starting point for your custom decoding method is a model repository just like any other. The model to add to this repository should be the model you've designed your method with, and it is meant to be part of a working self-contained model-generate pair. When the model in this repository is loaded, your custom decoding method will override `generate`. Don't worry -- your decoding method can still be loaded with any other Transformers model, as explained in the section above.
If you simply want to copy an existing model, you can do
```py
from transformers import AutoModelForCausalLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained("source/model_repo")
model = AutoModelForCausalLM.from_pretrained("source/model_repo")
tokenizer.save_pretrained("your/decoding_method", push_to_hub=True)
model.save_pretrained("your/decoding_method", push_to_hub=True)
```
#### generate.py
This is the core of your decoding method. It *must* contain a method named `generate`, and this method *must* contain a `model` argument as its first argument. `model` is the model instance, which means you have access to all attributes and methods in the model, including the ones defined in [`GenerationMixin`] (like the base `generate` method).
> [!WARNING]
> `generate.py` must be placed in a folder named `custom_generate`, and not at the root level of the repository. The file paths for this feature are hardcoded.
Under the hood, when the base [`~GenerationMixin.generate`] method is called with a `custom_generate` argument, it first checks its Python requirements (if any), then locates the custom `generate` method in `generate.py`, and finally calls the custom `generate`. All received arguments and `model` are forwarded to your custom `generate` method, with the exception of the arguments used to trigger the custom generation (`trust_remote_code` and `custom_generate`).
This means your `generate` can have a mix of original and custom arguments (as well as a different output type) as shown below.
```py
import torch
def generate(model, input_ids, generation_config=None, left_padding=None, **kwargs):
generation_config = generation_config or model.generation_config # default to the model generation config
cur_length = input_ids.shape[1]
max_length = generation_config.max_length or cur_length + generation_config.max_new_tokens
# Example of custom argument: add `left_padding` (integer) pad tokens before the prompt
if left_padding is not None:
if not isinstance(left_padding, int) or left_padding < 0:
raise ValueError(f"left_padding must be an integer larger than 0, but is {left_padding}")
pad_token = kwargs.pop("pad_token", None) or generation_config.pad_token_id or model.config.pad_token_id
if pad_token is None:
raise ValueError("pad_token is not defined")
batch_size = input_ids.shape[0]
pad_tensor = torch.full(size=(batch_size, left_padding), fill_value=pad_token).to(input_ids.device)
input_ids = torch.cat((pad_tensor, input_ids), dim=1)
cur_length = input_ids.shape[1]
# Simple greedy decoding loop
while cur_length < max_length:
logits = model(input_ids).logits
next_token_logits = logits[:, -1, :]
next_tokens = torch.argmax(next_token_logits, dim=-1)
input_ids = torch.cat((input_ids, next_tokens[:, None]), dim=-1)
cur_length += 1
return input_ids
```
Follow the recommended practices below to ensure your custom decoding method works as expected.
- Feel free to reuse the logic for validation and input preparation in the original [`~GenerationMixin.generate`].
- Pin the `transformers` version in the requirements if you use any private method/attribute in `model`.
- You can add other files in the `custom_generate` folder, and use relative imports.
- Consider adding model validation, input validation, or even a separate test file to help users sanity-check your code in their environment.
#### requirements.txt
You can optionally specify additional Python requirements in a `requirements.txt` file inside the `custom_generate` folder. These are checked at runtime and an exception will be thrown if they're missing, nudging users to update their environment accordingly.
#### README.md
The root level `README.md` in the model repository usually describes the model therein. However, since the focus of the repository is the custom decoding method, we highly recommend to shift its focus towards describing the custom decoding method. In addition to a description of the method, we recommend documenting any input and/or output differences to the original [`~GenerationMixin.generate`]. This way, users can focus on what's new, and rely on Transformers docs for generic implementation details.
For discoverability, we highly recommend you to add the `custom_generate` tag to your repository. To do so, the top of your `README.md` file should look like the example below. After you push the file, you should see the tag in your repository!
```
---
library_name: transformers
tags:
- custom_generate
---
(your markdown content here)
```
Recommended practices:
- Document input and output differences in [`~GenerationMixin.generate`].
- Add self-contained examples to enable quick experimentation.
- Describe soft-requirements such as if the method only works well with a certain family of models.

# GPU selection
During distributed training, you can specify the number of GPUs to use and in what order. This can be useful when you have GPUs with different computing power and you want to use the faster GPU first. Or you could only use a subset of the available GPUs. The selection process works for both [DistributedDataParallel](https://pytorch.org/docs/stable/generated/torch.nn.parallel.DistributedDataParallel.html) and [DataParallel](https://pytorch.org/docs/stable/generated/torch.nn.DataParallel.html). You don't need Accelerate or [DeepSpeed integration](./main_classes/deepspeed).
This guide will show you how to select the number of GPUs to use and the order to use them in.
## Number of GPUs
For example, if there are 4 GPUs and you only want to use the first 2, run the command below.
<hfoptions id="select-gpu">
<hfoption id="torchrun">
Use the `--nproc_per_node` to select how many GPUs to use.
```bash
torchrun --nproc_per_node=2 trainer-program.py ...
```
</hfoption>
<hfoption id="Accelerate">
Use `--num_processes` to select how many GPUs to use.
```bash
accelerate launch --num_processes 2 trainer-program.py ...
```
</hfoption>
<hfoption id="DeepSpeed">
Use `--num_gpus` to select how many GPUs to use.
```bash
deepspeed --num_gpus 2 trainer-program.py ...
```
</hfoption>
</hfoptions>
### Order of GPUs
To select specific GPUs to use and their order, configure the `CUDA_VISIBLE_DEVICES` environment variable. It is easiest to set the environment variable in `~/bashrc` or another startup config file. `CUDA_VISIBLE_DEVICES` is used to map which GPUs are used. For example, if there are 4 GPUs (0, 1, 2, 3) and you only want to run GPUs 0 and 2:
```bash
CUDA_VISIBLE_DEVICES=0,2 torchrun trainer-program.py ...
```
Only the 2 physical GPUs (0 and 2) are "visible" to PyTorch and these are mapped to `cuda:0` and `cuda:1` respectively. You can also reverse the order of the GPUs to use 2 first. The mapping becomes `cuda:1` for GPU 0 and `cuda:0` for GPU 2.
```bash
CUDA_VISIBLE_DEVICES=2,0 torchrun trainer-program.py ...
```
You can also set the `CUDA_VISIBLE_DEVICES` environment variable to an empty value to create an environment without GPUs.
```bash
CUDA_VISIBLE_DEVICES= python trainer-program.py ...
```
> [!WARNING]
> As with any environment variable, they can be exported instead of being added to the command line. However, this is not recommended because it can be confusing if you forget how the environment variable was set up and you end up using the wrong GPUs. Instead, it is common practice to set the environment variable for a specific training run on the same command line.
`CUDA_DEVICE_ORDER` is an alternative environment variable you can use to control how the GPUs are ordered. You can order according to the following.
1. PCIe bus IDs that matches the order of [`nvidia-smi`](https://developer.nvidia.com/nvidia-system-management-interface) and [`rocm-smi`](https://rocm.docs.amd.com/projects/rocm_smi_lib/en/latest/.doxygen/docBin/html/index.html) for NVIDIA and AMD GPUs respectively.
```bash
export CUDA_DEVICE_ORDER=PCI_BUS_ID
```
2. GPU compute ability.
```bash
export CUDA_DEVICE_ORDER=FASTEST_FIRST
```
The `CUDA_DEVICE_ORDER` is especially useful if your training setup consists of an older and newer GPU, where the older GPU appears first, but you cannot physically swap the cards to make the newer GPU appear first. In this case, set `CUDA_DEVICE_ORDER=FASTEST_FIRST` to always use the newer and faster GPU first (`nvidia-smi` or `rocm-smi` still reports the GPUs in their PCIe order). Or you could also set `export CUDA_VISIBLE_DEVICES=1,0`.

# Import Utilities
This page goes through the transformers utilities to enable lazy and fast object import.
While we strive for minimal dependencies, some models have specific dependencies requirements that cannot be
worked around. We don't want for all users of `transformers` to have to install those dependencies to use other models,
we therefore mark those as soft dependencies rather than hard dependencies.
The transformers toolkit is not made to error-out on import of a model that has a specific dependency; instead, an
object for which you are lacking a dependency will error-out when calling any method on it. As an example, if
`torchvision` isn't installed, the fast image processors will not be available.
This object is still importable:
```python
>>> from transformers import DetrImageProcessorFast
>>> print(DetrImageProcessorFast)
<class 'DetrImageProcessorFast'>
```
However, no method can be called on that object:
```python
>>> DetrImageProcessorFast.from_pretrained()
ImportError:
DetrImageProcessorFast requires the Torchvision library but it was not found in your environment. Checkout the instructions on the
installation page: https://pytorch.org/get-started/locally/ and follow the ones that match your environment.
Please note that you may need to restart your runtime after installation.
```
Let's see how to specify specific object dependencies.
## Specifying Object Dependencies
### Filename-based
All objects under a given filename have an automatic dependency to the tool linked to the filename
**TensorFlow**: All files starting with `modeling_tf_` have an automatic TensorFlow dependency.
**Flax**: All files starting with `modeling_flax_` have an automatic Flax dependency
**PyTorch**: All files starting with `modeling_` and not valid with the above (TensorFlow and Flax) have an automatic
PyTorch dependency
**Tokenizers**: All files starting with `tokenization_` and ending with `_fast` have an automatic `tokenizers` dependency
**Vision**: All files starting with `image_processing_` have an automatic dependency to the `vision` dependency group;
at the time of writing, this only contains the `pillow` dependency.
**Vision + Torch + Torchvision**: All files starting with `image_processing_` and ending with `_fast` have an automatic
dependency to `vision`, `torch`, and `torchvision`.
All of these automatic dependencies are added on top of the explicit dependencies that are detailed below.
### Explicit Object Dependencies
We add a method called `requires` that is used to explicitly specify the dependencies of a given object. As an
example, the `Trainer` class has two hard dependencies: `torch` and `accelerate`. Here is how we specify these
required dependencies:
```python
from .utils.import_utils import requires
@requires(backends=("torch", "accelerate"))
class Trainer:
...
```
Backends that can be added here are all the backends that are available in the `import_utils.py` module.
Additionally, specific versions can be specified in each backend. For example, this is how you would specify
a requirement on torch>=2.6 on the `Trainer` class:
```python
from .utils.import_utils import requires
@requires(backends=("torch>=2.6", "accelerate"))
class Trainer:
...
```
You can specify the following operators: `==`, `>`, `>=`, `<`, `<=`, `!=`.

#### Saving tensors to disk
Some model adders may benefit from logging full tensor values to disk to support, for example, numerical analysis
across implementations.
Set `use_repr=False` to write tensors to disk using [SafeTensors](https://huggingface.co/docs/safetensors/en/index).
```python
with model_addition_debugger_context(
model,
debug_path="optional_path_to_your_directory",
do_prune_layers=False,
use_repr=False, # Defaults to True
):
output = model.forward(**inputs)
```
When using `use_repr=False`, tensors are written to the same disk location as the `_SUMMARY.json` and
`_FULL_TENSORS.json` files. The `value` property of entries in the `_FULL_TENSORS.json` file will contain a relative
path reference to the associated `.safetensors` file. Each tensor is written to its own file as the `data` property of
the state dictionary. File names are constructed using the `module_path` as a prefix with a few possible postfixes that
are built recursively.
* Module inputs are denoted with the `_inputs` and outputs by `_outputs`.
* `list` and `tuple` instances, such as `args` or function return values, will be postfixed with `_{index}`.
* `dict` instances will be postfixed with `_{key}`.
### Comparing between implementations
Once the forward passes of two models have been traced by the debugger, one can compare the `json` output files. See
below: we can see slight differences between these two implementations' key projection layer. Inputs are mostly
identical, but not quite. Looking through the file differences makes it easier to pinpoint which layer is wrong.
![download-icon](https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/transformers/files_difference_debugging.png)
### Limitations and scope
This feature will only work for torch-based models, and would require more work and case-by-case approach for say
`jax`-based models that are usually compiled. Models relying heavily on external kernel calls may work, but trace will
probably miss some things. Regardless, any python implementation that aims at mimicking another implementation can be
traced once instead of reran N times with breakpoints.
If you pass `do_prune_layers=False` to your model debugger, ALL the layers will be outputted to `json`. Else, only the
first and last layer will be shown. This is useful when some layers (typically cross-attention) appear only after N
layers.

The key-value (KV) vectors are used to calculate attention scores. For autoregressive models, KV scores are calculated *every* time because the model predicts one token at a time. Each prediction depends on the previous tokens, which means the model performs the same computations each time.
A KV *cache* stores these calculations so they can be reused without recomputing them. Efficient caching is crucial for optimizing model performance because it reduces computation time and improves response rates. Refer to the [Caching](./cache_explanation) doc for a more detailed explanation about how a cache works.

### Sink cache
[`SinkCache`] is capable of generating very long sequences ("infinite length" according to the paper) by only retaining a few initial tokens from the sequence. These are called the *sink tokens* because they account for a significant portion of the attention scores during generation. Subsequent tokens are discarded on a sliding windowed basis, and only the latest `window_size` tokens are kept. This means most of the previous knowledge is discarded.
The sink tokens allow a model to maintain stable performance even when it's dealing with very long text sequences.
Enable [`SinkCache`] by initializing it first with the [window_length](https://hf.co/docs/transformers/main/en/internal/generation_utils#transformers.SinkCache.window_length) and [num_sink_tokens](https://hf.co/docs/transformers/main/en/internal/generation_utils#transformers.SinkCache.num_sink_tokens) parameters before passing it to [past_key_values](https://hf.co/docs/transformers/internal/generation_utils#transformers.generation.GenerateDecoderOnlyOutput.past_key_values) in [`~GenerationMixin.generate`].
```py
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, SinkCache
tokenizer = AutoTokenizer.from_pretrained("meta-llama/Llama-2-7b-chat-hf")
model = AutoModelForCausalLM.from_pretrained("meta-llama/Llama-2-7b-chat-hf", torch_dtype=torch.float16).to("cuda:0")
inputs = tokenizer("This is a long story about unicorns, fairies and magic.", return_tensors="pt").to(model.device)
past_key_values = SinkCache(window_length=256, num_sink_tokens=4)
out = model.generate(**inputs, do_sample=False, max_new_tokens=30, past_key_values=past_key_values)
tokenizer.batch_decode(out, skip_special_tokens=True)[0]

```
## Speed optimized caches
The default [`DynamicCache`] prevents you from taking advantage of just-in-time (JIT) optimizations because the cache size isn't fixed. JIT optimizations enable you to maximize latency at the expense of memory usage. All of the following cache types are compatible with JIT optimizations like [torch.compile](./llm_optims#static-kv-cache-and-torchcompile) to accelerate generation.

Text generation is the most popular application for large language models (LLMs). A LLM is trained to generate the next word (token) given some initial text (prompt) along with its own generated outputs up to a predefined length or when it reaches an end-of-sequence (`EOS`) token.
In Transformers, the [`~GenerationMixin.generate`] API handles text generation, and it is available for all models with generative capabilities. This guide will show you the basics of text generation with [`~GenerationMixin.generate`] and some common pitfalls to avoid.

[`~GenerationMixin.generate`] is a powerful tool that can be heavily customized. This can be daunting for a new users.

| Option name | Type | Simplified description |
|---|---|---|
| `max_new_tokens` | `int` | Controls the maximum generation length. Be sure to define it, as it usually defaults to a small value. |
| `do_sample` | `bool` | Defines whether generation will sample the next token (`True`), or is greedy instead (`False`). Most use cases should set this flag to `True`. Check [this guide](./generation_strategies.md) for more information. |
| `temperature` | `float` | How unpredictable the next selected token will be. High values (`>0.8`) are good for creative tasks, low values (e.g. `<0.4`) for tasks that require "thinking". Requires `do_sample=True`. |
| `num_beams` | `int` | When set to `>1`, activates the beam search algorithm. Beam search is good on input-grounded tasks. Check [this guide](./generation_strategies.md) for more information. |
| `repetition_penalty` | `float` | Set it to `>1.0` if you're seeing the model repeat itself often. Larger values apply a larger penalty. |
| `eos_token_id` | `List[int]` | The token(s) that will cause generation to stop. The default value is usually good, but you can specify a different token. |

# Agents & Tools
<Tip warning={true}>
Transformers Agents is an experimental API which is subject to change at any time. Results returned by the agents
can vary as the APIs or underlying models are prone to change.
</Tip>
To learn more about agents and tools make sure to read the [introductory guide](../transformers_agents). This page
contains the API docs for the underlying classes.
## Agents
We provide two types of agents, based on the main [`Agent`] class:
- [`CodeAgent`] acts in one shot, generating code to solve the task, then executes it at once.
- [`ReactAgent`] acts step by step, each step consisting of one thought, then one tool call and execution. It has two classes:
- [`ReactJsonAgent`] writes its tool calls in JSON.
- [`ReactCodeAgent`] writes its tool calls in Python code.

## Engines
You're free to create and use your own engines to be usable by the Agents framework.
These engines have the following specification:
1. Follow the [messages format](../chat_templating.md) for its input (`List[Dict[str, str]]`) and return a string.
2. Stop generating outputs *before* the sequences passed in the argument `stop_sequences`
### TransformersEngine
For convenience, we have added a `TransformersEngine` that implements the points above, taking a pre-initialized `Pipeline` as input.
```python
>>> from transformers import AutoModelForCausalLM, AutoTokenizer, pipeline, TransformersEngine
>>> model_name = "HuggingFaceTB/SmolLM-135M-Instruct"
>>> tokenizer = AutoTokenizer.from_pretrained(model_name)
>>> model = AutoModelForCausalLM.from_pretrained(model_name)
>>> pipe = pipeline("text-generation", model=model, tokenizer=tokenizer)
>>> engine = TransformersEngine(pipe)
>>> engine([{"role": "user", "content": "Ok!"}], stop_sequences=["great"])
"What a "
```
[[autodoc]] TransformersEngine
### HfApiEngine
The `HfApiEngine` is an engine that wraps an [HF Inference API](https://huggingface.co/docs/api-inference/index) client for the execution of the LLM.
```python
>>> from transformers import HfApiEngine
>>> messages = [
... {"role": "user", "content": "Hello, how are you?"},
... {"role": "assistant", "content": "I'm doing great. How can I help you today?"},
... {"role": "user", "content": "No need to help, take it easy."},
... ]
>>> HfApiEngine()(messages, stop_sequences=["conversation"])
"That's very kind of you to say! It's always nice to have a relaxed "
```
[[autodoc]] HfApiEngine
## Agent Types
Agents can handle any type of object in-between tools; tools, being completely multimodal, can accept and return
text, image, audio, video, among other types. In order to increase compatibility between tools, as well as to
correctly render these returns in ipython (jupyter, colab, ipython notebooks, ...), we implement wrapper classes
around these types.
The wrapped objects should continue behaving as initially; a text object should still behave as a string, an image
object should still behave as a `PIL.Image`.
These types have three specific purposes:
- Calling `to_raw` on the type should return the underlying object
- Calling `to_string` on the type should return the object as a string: that can be the string in case of an `AgentText`
but will be the path of the serialized version of the object in other instances
- Displaying it in an ipython kernel should display the object correctly

# Video Processor
A **Video Processor** is a utility responsible for preparing input features for video models, as well as handling the post-processing of their outputs. It provides transformations such as resizing, normalization, and conversion into PyTorch.
The video processor extends the functionality of image processors by allowing Vision Large Language Models (VLMs) to handle videos with a distinct set of arguments compared to images. It serves as the bridge between raw video data and the model, ensuring that input features are optimized for the VLM.
When adding a new VLM or updating an existing one to enable distinct video preprocessing, saving and reloading the processor configuration will store the video related arguments in a dedicated file named `video_preprocessing_config.json`. Don't worry if you haven't updated your VLM, the processor will try to load video related configurations from a file named `preprocessing_config.json`.
### Usage Example
Here's an example of how to load a video processor with [`llava-hf/llava-onevision-qwen2-0.5b-ov-hf`](https://huggingface.co/llava-hf/llava-onevision-qwen2-0.5b-ov-hf) model:
```python
from transformers import AutoVideoProcessor
processor = AutoVideoProcessor.from_pretrained("llava-hf/llava-onevision-qwen2-0.5b-ov-hf")
```
Currently, if using base image processor for videos, it processes video data by treating each frame as an individual image and applying transformations frame-by-frame. While functional, this approach is not highly efficient. Using `AutoVideoProcessor` allows us to take advantage of **fast video processors**, leveraging the [torchvision](https://pytorch.org/vision/stable/index.html) library. Fast processors handle the whole batch of videos at once, without iterating over each video or frame. These updates introduce GPU acceleration and significantly enhance processing speed, especially for tasks requiring high throughput.
Fast video processors are available for all models and are loaded by default when an `AutoVideoProcessor` is initialized. When using a fast video processor, you can also set the `device` argument to specify the device on which the processing should be done. By default, the processing is done on the same device as the inputs if the inputs are tensors, or on the CPU otherwise. For even more speed improvement, we can compile the processor when using 'cuda' as device.
```python
import torch
from transformers.video_utils import load_video
from transformers import AutoVideoProcessor
video = load_video("video.mp4")
processor = AutoVideoProcessor.from_pretrained("llava-hf/llava-onevision-qwen2-0.5b-ov-hf", device="cuda")
processor = torch.compile(processor)
processed_video = processor(video, return_tensors="pt")
```

- Embedding size E is different from hidden size H justified because the embeddings are context independent (one embedding vector represents one token), whereas hidden states are context dependent (one hidden state represents a sequence of tokens) so it's more logical to have H >> E. Also, the embedding matrix is large since it's V x E (V being the vocab size). If E < H, it has less parameters.
- Layers are split in groups that share parameters (to save memory).
Next sentence prediction is replaced by a sentence ordering prediction: in the inputs, we have two sentences A and B (that are consecutive) and we either feed A followed by B or B followed by A. The model must predict if they have been swapped or not.

# ALIGN
[ALIGN](https://huggingface.co/papers/2102.05918) is pretrained on a noisy 1.8 billion alttext and image pair dataset to show that scale can make up for the noise. It uses a dualencoder architecture, [EfficientNet](./efficientnet) for images and [BERT](./bert) for text, and a contrastive loss to align similar imagetext embeddings together while pushing different embeddings apart. Once trained, ALIGN can encode any image and candidate captions into a shared vector space for zeroshot retrieval or classification without requiring extra labels. This scalefirst approach reduces dataset curation costs and powers stateoftheart imagetext retrieval and zeroshot ImageNet classification.

## Overview
> [!TIP]
> Click on the ALIGN models in the right sidebar for more examples of how to apply ALIGN to different vision and text related tasks.
The ALIGN model was proposed in [Scaling Up Visual and Vision-Language Representation Learning With Noisy Text Supervision](https://arxiv.org/abs/2102.05918) by Chao Jia, Yinfei Yang, Ye Xia, Yi-Ting Chen, Zarana Parekh, Hieu Pham, Quoc V. Le, Yunhsuan Sung, Zhen Li, Tom Duerig. ALIGN is a multi-modal vision and language model. It can be used for image-text similarity and for zero-shot image classification. ALIGN features a dual-encoder architecture with [EfficientNet](efficientnet) as its vision encoder and [BERT](bert) as its text encoder, and learns to align visual and text representations with contrastive learning. Unlike previous work, ALIGN leverages a massive noisy dataset and shows that the scale of the corpus can be used to achieve SOTA representations with a simple recipe.
The example below demonstrates zero-shot image classification with [`Pipeline`] or the [`AutoModel`] class.
The abstract from the paper is the following:
<hfoptions id="usage">
*Pre-trained representations are becoming crucial for many NLP and perception tasks. While representation learning in NLP has transitioned to training on raw text without human annotations, visual and vision-language representations still rely heavily on curated training datasets that are expensive or require expert knowledge. For vision applications, representations are mostly learned using datasets with explicit class labels such as ImageNet or OpenImages. For vision-language, popular datasets like Conceptual Captions, MSCOCO, or CLIP all involve a non-trivial data collection (and cleaning) process. This costly curation process limits the size of datasets and hence hinders the scaling of trained models. In this paper, we leverage a noisy dataset of over one billion image alt-text pairs, obtained without expensive filtering or post-processing steps in the Conceptual Captions dataset. A simple dual-encoder architecture learns to align visual and language representations of the image and text pairs using a contrastive loss. We show that the scale of our corpus can make up for its noise and leads to state-of-the-art representations even with such a simple learning scheme. Our visual representation achieves strong performance when transferred to classification tasks such as ImageNet and VTAB. The aligned visual and language representations enables zero-shot image classification and also set new state-of-the-art results on Flickr30K and MSCOCO image-text retrieval benchmarks, even when compared with more sophisticated cross-attention models. The representations also enable cross-modality search with complex text and text + image queries.*
<hfoption id="Pipeline">
This model was contributed by [Alara Dirik](https://huggingface.co/adirik).
The original code is not released, this implementation is based on the Kakao Brain implementation based on the original paper.
```py
import torch
from transformers import pipeline
## Usage example
pipeline = pipeline(
task="zero-shot-image-classification",
model="kakaobrain/align-base",
device=0,
torch_dtype=torch.bfloat16
)
ALIGN uses EfficientNet to get visual features and BERT to get the text features. Both the text and visual features are then projected to a latent space with identical dimension. The dot product between the projected image and text features is then used as a similarity score.
candidate_labels = [
"a photo of a dog",
"a photo of a cat",
"a photo of a person"
]
[`AlignProcessor`] wraps [`EfficientNetImageProcessor`] and [`BertTokenizer`] into a single instance to both encode the text and preprocess the images. The following example shows how to get the image-text similarity scores using [`AlignProcessor`] and [`AlignModel`].
pipeline("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg", candidate_labels=candidate_labels)

text_embeds = text_embeds / text_embeds.norm(p=2, dim=-1, keepdim=True)
logits = (image_embeds @ text_embeds.T) * 100.0
probs = logits.softmax(dim=-1).cpu().squeeze()
for label, score in zip(candidate_labels, probs):

# we can take the softmax to get the label probabilities
probs = logits_per_image.softmax(dim=1)

```

## Notes
- ALIGN projects the text and visual features into latent space and the dot product between the projected image and text features is used as the similarity score. The example below demonstrates how to calculate the image-text similarity score with [`AlignProcessor`] and [`AlignModel`].
```py
# Example of using ALIGN for image-text similarity
from transformers import AlignProcessor, AlignModel
import torch
from PIL import Image
import requests
from io import BytesIO
# Load processor and model
processor = AlignProcessor.from_pretrained("kakaobrain/align-base")

response = requests.get(url)
image = Image.open(BytesIO(response.content)) # Convert the downloaded bytes to a PIL Image
texts = ["a photo of a cat", "a photo of a dog"]
# Process image and text inputs
inputs = processor(images=image, text=texts, return_tensors="pt")
# Get the embeddings
with torch.no_grad():
outputs = model(**inputs)
image_embeds = outputs.image_embeds
text_embeds = outputs.text_embeds
# Normalize embeddings for cosine similarity
image_embeds = image_embeds / image_embeds.norm(dim=1, keepdim=True)
text_embeds = text_embeds / text_embeds.norm(dim=1, keepdim=True)
# Calculate similarity scores
similarity_scores = torch.matmul(text_embeds, image_embeds.T)
# Print raw scores
print("Similarity scores:", similarity_scores)
# Convert to probabilities
probs = torch.nn.functional.softmax(similarity_scores, dim=0)
print("Probabilities:", probs)
# Get the most similar text
most_similar_idx = similarity_scores.argmax().item()
print(f"Most similar text: '{texts[most_similar_idx]}'")
```

# Aria
[Aria](https://huggingface.co/papers/2410.05993) is a multimodal mixture-of-experts (MoE) model. The goal of this model is to open-source a training recipe for creating a multimodal native model from scratch. Aria has 3.9B and 3.5B activated parameters per visual and text token respectively. Text is handled by a MoE decoder and visual inputs are handled by a lightweight visual encoder. It is trained in 4 stages, language pretraining, multimodal pretraining, multimodal long-context pretraining, and multimodal post-training.

## Overview

The Aria model was proposed in [Aria: An Open Multimodal Native Mixture-of-Experts Model](https://huggingface.co/papers/2410.05993) by Li et al. from the Rhymes.AI team.
The example below demonstrates how to generate text based on an image with [`Pipeline`] or the [`AutoModel`] class.
Aria is an open multimodal-native model with best-in-class performance across a wide range of multimodal, language, and coding tasks. It has a Mixture-of-Experts architecture, with respectively 3.9B and 3.5B activated parameters per visual token and text token.
<hfoptions id="usage">
<hfoption id="Pipeline">
The abstract from the paper is the following:
*Information comes in diverse modalities. Multimodal native AI models are essential to integrate real-world information and deliver comprehensive understanding. While proprietary multimodal native models exist, their lack of openness imposes obstacles for adoptions, let alone adaptations. To fill this gap, we introduce Aria, an open multimodal native model with best-in-class performance across a wide range of multimodal, language, and coding tasks. Aria is a mixture-of-expert model with 3.9B and 3.5B activated parameters per visual token and text token, respectively. It outperforms Pixtral-12B and Llama3.2-11B, and is competitive against the best proprietary models on various multimodal tasks. We pre-train Aria from scratch following a 4-stage pipeline, which progressively equips the model with strong capabilities in language understanding, multimodal understanding, long context window, and instruction following. We open-source the model weights along with a codebase that facilitates easy adoptions and adaptations of Aria in real-world applications.*

Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
The example below uses [torchao](../quantization/torchao) to only quantize the weights to int4 and the [rhymes-ai/Aria-sequential_mlp](https://huggingface.co/rhymes-ai/Aria-sequential_mlp) checkpoint. This checkpoint replaces grouped GEMM with `torch.nn.Linear` layers for easier quantization.

## Padding-Free Training
Bamba supports padding-free training in which distinct training examples can be concatenated
together while nevertheless processing the inputs as though they belonged to separate batches. When
the examples are of varying lengths, padding-free training can provide significant speed ups and
memory savings compared to batching the examples together and using padding, as the unnecessary
compute and memory due to padding is avoided entirely. The performance gains depend on factors such
as the model and the data distribution, but throughput gains up to [~2x are commonly
seen](https://github.com/huggingface/transformers/pull/35861#issue-2807873129).
Using padding-free training with Bamba requires the `flash-attn`, `mamba-ssm`, and `causal-conv1d`
packages, and the following arguments must be passed to the model in addition to `input_ids` and
`labels`:
* `position_ids: torch.LongTensor`: the position index of each token in each sequence.
* `seq_idx: torch.IntTensor`: the index of each sequence in the batch.
* Each of the [`FlashAttentionKwargs`]
* `cu_seq_lens_q: torch.LongTensor`: The cumulative sequence lengths of all queries.
* `cu_seq_lens_k: torch.LongTensor`: The cumulative sequence lengths of all keys.
* `max_length_q: int`: the longest query length in the batch.
* `max_length_k: int`: the longest key length in the batch.
The `attention_mask` inputs should not be provided. The [`DataCollatorWithFlattening`] can be used
to programmatically generate the above set of additional arguments using `return_seq_idx=True` and
`return_flash_attn_kwargs=True`. See [this blog post](https://huggingface.co/blog/packing-with-FA2)
for additional information.

# BART
[BART](https://huggingface.co/papers/1910.13461) is a sequence-to-sequence model that combines the pretraining objectives from BERT and GPT. Its pretrained by corrupting text in different ways like deleting words, shuffling sentences, or masking tokens and learning how to fix it. The encoder encodes the corrupted document and the corrupted text is fixed by the decoder. As it learns to recover the original text, BART gets really good at both understanding and generating language.
## Overview
You can find all the original BART checkpoints under the [AI at Meta](https://huggingface.co/facebook?search_models=bart) organization.
The Bart model was proposed in [BART: Denoising Sequence-to-Sequence Pre-training for Natural Language Generation,
Translation, and Comprehension](https://arxiv.org/abs/1910.13461) by Mike Lewis, Yinhan Liu, Naman Goyal, Marjan
Ghazvininejad, Abdelrahman Mohamed, Omer Levy, Ves Stoyanov and Luke Zettlemoyer on 29 Oct, 2019.
The example below demonstrates how to predict the `[MASK]` token with [`Pipeline`], [`AutoModel`], and from the command line.
According to the abstract,
<hfoptions id="usage">
<hfoption id="Pipeline">
- Bart uses a standard seq2seq/machine translation architecture with a bidirectional encoder (like BERT) and a
left-to-right decoder (like GPT).
- The pretraining task involves randomly shuffling the order of the original sentences and a novel in-filling scheme,
where spans of text are replaced with a single mask token.
- BART is particularly effective when fine tuned for text generation but also works well for comprehension tasks. It
matches the performance of RoBERTa with comparable training resources on GLUE and SQuAD, achieves new
state-of-the-art results on a range of abstractive dialogue, question answering, and summarization tasks, with gains
of up to 6 ROUGE.
```py
import torch
from transformers import pipeline
This model was contributed by [sshleifer](https://huggingface.co/sshleifer). The authors' code can be found [here](https://github.com/pytorch/fairseq/tree/master/examples/bart).
pipeline = pipeline(
task="fill-mask",
model="facebook/bart-large",
torch_dtype=torch.float16,
device=0
)
pipeline("Plants create <mask> through a process known as photosynthesis.")
## Usage tips:
```
</hfoption>
<hfoption id="AutoModel">
- BART is a model with absolute position embeddings so it's usually advised to pad the inputs on the right rather than
the left.
- Sequence-to-sequence model with an encoder and a decoder. Encoder is fed a corrupted version of the tokens, decoder is fed the original tokens (but has a mask to hide the future words like a regular transformers decoder). A composition of the following transformations are applied on the pretraining tasks for the encoder:
```py
import torch
from transformers import AutoModelForMaskedLM, AutoTokenizer
* mask random tokens (like in BERT)
* delete random tokens
* mask a span of k tokens with a single mask token (a span of 0 tokens is an insertion of a mask token)
* permute sentences
* rotate the document to make it start at a specific token
tokenizer = AutoTokenizer.from_pretrained(
"facebook/bart-large",
)
model = AutoModelForMaskedLM.from_pretrained(
"facebook/bart-large",
torch_dtype=torch.float16,
device_map="auto",
attn_implementation="sdpa"
)
inputs = tokenizer("Plants create <mask> through a process known as photosynthesis.", return_tensors="pt").to("cuda")
## Implementation Notes
with torch.no_grad():
outputs = model(**inputs)
predictions = outputs.logits
- Bart doesn't use `token_type_ids` for sequence classification. Use [`BartTokenizer`] or
[`~BartTokenizer.encode`] to get the proper splitting.
- The forward pass of [`BartModel`] will create the `decoder_input_ids` if they are not passed.
This is different than some other modeling APIs. A typical use case of this feature is mask filling.
- Model predictions are intended to be identical to the original implementation when
`forced_bos_token_id=0`. This only works, however, if the string you pass to
[`fairseq.encode`] starts with a space.
- [`~generation.GenerationMixin.generate`] should be used for conditional generation tasks like
summarization, see the example in that docstrings.
- Models that load the *facebook/bart-large-cnn* weights will not have a `mask_token_id`, or be able to perform
mask-filling tasks.
masked_index = torch.where(inputs['input_ids'] == tokenizer.mask_token_id)[1]
predicted_token_id = predictions[0, masked_index].argmax(dim=-1)
predicted_token = tokenizer.decode(predicted_token_id)
## Mask Filling
print(f"The predicted token is: {predicted_token}")
The `facebook/bart-base` and `facebook/bart-large` checkpoints can be used to fill multi-token masks.
```python
from transformers import BartForConditionalGeneration, BartTokenizer
model = BartForConditionalGeneration.from_pretrained("facebook/bart-large", forced_bos_token_id=0)
tok = BartTokenizer.from_pretrained("facebook/bart-large")
example_english_phrase = "UN Chief Says There Is No <mask> in Syria"
batch = tok(example_english_phrase, return_tensors="pt")
generated_ids = model.generate(batch["input_ids"])
assert tok.batch_decode(generated_ids, skip_special_tokens=True) == [
"UN Chief Says There Is No Plan to Stop Chemical Weapons in Syria"
]
```

## BERTweet
## Overview
[BERTweet](https://huggingface.co/papers/2005.10200) shares the same architecture as [BERT-base](./bert), but its pretrained like [RoBERTa](./roberta) on English Tweets. It performs really well on Tweet-related tasks like part-of-speech tagging, named entity recognition, and text classification.
The BERTweet model was proposed in [BERTweet: A pre-trained language model for English Tweets](https://www.aclweb.org/anthology/2020.emnlp-demos.2.pdf) by Dat Quoc Nguyen, Thanh Vu, Anh Tuan Nguyen.
The abstract from the paper is the following:
You can find all the original BERTweet checkpoints under the [VinAI Research](https://huggingface.co/vinai?search_models=BERTweet) organization.
*We present BERTweet, the first public large-scale pre-trained language model for English Tweets. Our BERTweet, having
the same architecture as BERT-base (Devlin et al., 2019), is trained using the RoBERTa pre-training procedure (Liu et
al., 2019). Experiments show that BERTweet outperforms strong baselines RoBERTa-base and XLM-R-base (Conneau et al.,
2020), producing better performance results than the previous state-of-the-art models on three Tweet NLP tasks:
Part-of-speech tagging, Named-entity recognition and text classification.*
> [!TIP]
> Refer to the [BERT](./bert) docs for more examples of how to apply BERTweet to different language tasks.
This model was contributed by [dqnguyen](https://huggingface.co/dqnguyen). The original code can be found [here](https://github.com/VinAIResearch/BERTweet).
The example below demonstrates how to predict the `<mask>` token with [`Pipeline`], [`AutoModel`], and from the command line.
## Usage example
<hfoptions id="usage">
<hfoption id="Pipeline">
```python
>>> import torch
>>> from transformers import AutoModel, AutoTokenizer
```py
import torch
from transformers import pipeline
>>> bertweet = AutoModel.from_pretrained("vinai/bertweet-base")
pipeline = pipeline(
task="fill-mask",
model="vinai/bertweet-base",
torch_dtype=torch.float16,
device=0
)
pipeline("Plants create <mask> through a process known as photosynthesis.")
```
</hfoption>
<hfoption id="AutoModel">
>>> # For transformers v4.x+:
>>> tokenizer = AutoTokenizer.from_pretrained("vinai/bertweet-base", use_fast=False)
```py
import torch
from transformers import AutoModelForMaskedLM, AutoTokenizer
>>> # For transformers v3.x:
>>> # tokenizer = AutoTokenizer.from_pretrained("vinai/bertweet-base")
tokenizer = AutoTokenizer.from_pretrained(
"vinai/bertweet-base",
)
model = AutoModelForMaskedLM.from_pretrained(
"vinai/bertweet-base",
torch_dtype=torch.float16,
device_map="auto"
)
inputs = tokenizer("Plants create <mask> through a process known as photosynthesis.", return_tensors="pt").to("cuda")
>>> # INPUT TWEET IS ALREADY NORMALIZED!
>>> line = "SC has first two presumptive cases of coronavirus , DHEC confirms HTTPURL via @USER :cry:"
with torch.no_grad():
outputs = model(**inputs)
predictions = outputs.logits
>>> input_ids = torch.tensor([tokenizer.encode(line)])
masked_index = torch.where(inputs['input_ids'] == tokenizer.mask_token_id)[1]
predicted_token_id = predictions[0, masked_index].argmax(dim=-1)
predicted_token = tokenizer.decode(predicted_token_id)
>>> with torch.no_grad():
... features = bertweet(input_ids) # Models outputs are now tuples
print(f"The predicted token is: {predicted_token}")
>>> # With TensorFlow 2.0+:
>>> # from transformers import TFAutoModel
>>> # bertweet = TFAutoModel.from_pretrained("vinai/bertweet-base")
```
</hfoption>
<hfoption id="transformers CLI">
<Tip>
```bash
echo -e "Plants create <mask> through a process known as photosynthesis." | transformers-cli run --task fill-mask --model vinai/bertweet-base --device 0
```
This implementation is the same as BERT, except for tokenization method. Refer to [BERT documentation](bert) for
API reference information.
</hfoption>
</hfoptions>
## Notes
- Use the [`AutoTokenizer`] or [`BertweetTokenizer`] because its preloaded with a custom vocabulary adapted to tweet-specific tokens like hashtags (#), mentions (@), emojis, and common abbreviations. Make sure to also install the [emoji](https://pypi.org/project/emoji/) library.
- Inputs should be padded on the right (`padding="max_length"`) because BERT uses absolute position embeddings.

# BigBird
[BigBird](https://huggingface.co/papers/2007.14062) is a transformer model built to handle sequence lengths up to 4096 compared to 512 for [BERT](./bert). Traditional transformers struggle with long inputs because attention gets really expensive as the sequence length grows. BigBird fixes this by using a sparse attention mechanism, which means it doesnt try to look at everything at once. Instead, it mixes in local attention, random attention, and a few global tokens to process the whole input. This combination gives it the best of both worlds. It keeps the computation efficient while still capturing enough of the sequence to understand it well. Because of this, BigBird is great at tasks involving long documents, like question answering, summarization, and genomic applications.

## Overview
You can find all the original BigBird checkpoints under the [Google](https://huggingface.co/google?search_models=bigbird) organization.
The BigBird model was proposed in [Big Bird: Transformers for Longer Sequences](https://arxiv.org/abs/2007.14062) by
Zaheer, Manzil and Guruganesh, Guru and Dubey, Kumar Avinava and Ainslie, Joshua and Alberti, Chris and Ontanon,
Santiago and Pham, Philip and Ravula, Anirudh and Wang, Qifan and Yang, Li and others. BigBird, is a sparse-attention
based transformer which extends Transformer based models, such as BERT to much longer sequences. In addition to sparse
attention, BigBird also applies global attention as well as random attention to the input sequence. Theoretically, it
has been shown that applying sparse, global, and random attention approximates full attention, while being
computationally much more efficient for longer sequences. As a consequence of the capability to handle longer context,
BigBird has shown improved performance on various long document NLP tasks, such as question answering and
summarization, compared to BERT or RoBERTa.

The abstract from the paper is the following:
The example below demonstrates how to predict the `[MASK]` token with [`Pipeline`], [`AutoModel`], and from the command line.
*Transformers-based models, such as BERT, have been one of the most successful deep learning models for NLP.
Unfortunately, one of their core limitations is the quadratic dependency (mainly in terms of memory) on the sequence
length due to their full attention mechanism. To remedy this, we propose, BigBird, a sparse attention mechanism that
reduces this quadratic dependency to linear. We show that BigBird is a universal approximator of sequence functions and
is Turing complete, thereby preserving these properties of the quadratic, full attention model. Along the way, our
theoretical analysis reveals some of the benefits of having O(1) global tokens (such as CLS), that attend to the entire
sequence as part of the sparse attention mechanism. The proposed sparse attention can handle sequences of length up to
8x of what was previously possible using similar hardware. As a consequence of the capability to handle longer context,
BigBird drastically improves performance on various NLP tasks such as question answering and summarization. We also
propose novel applications to genomics data.*

This model was contributed by [vasudevgupta](https://huggingface.co/vasudevgupta). The original code can be found
[here](https://github.com/google-research/bigbird).
```py
import torch
from transformers import pipeline
## Usage tips
pipeline = pipeline(
task="fill-mask",
model="google/bigbird-roberta-base",
torch_dtype=torch.float16,
device=0
)
pipeline("Plants create [MASK] through a process known as photosynthesis.")
```
</hfoption>
<hfoption id="AutoModel">
- For an in-detail explanation on how BigBird's attention works, see [this blog post](https://huggingface.co/blog/big-bird).
- BigBird comes with 2 implementations: **original_full** & **block_sparse**. For the sequence length < 1024, using
**original_full** is advised as there is no benefit in using **block_sparse** attention.
- The code currently uses window size of 3 blocks and 2 global blocks.
- Sequence length must be divisible by block size.
- Current implementation supports only **ITC**.
- Current implementation doesn't support **num_random_blocks = 0**
- BigBird is a model with absolute position embeddings so it's usually advised to pad the inputs on the right rather than
the left.
```py
import torch
from transformers import AutoModelForMaskedLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained(
"google/bigbird-roberta-base",
)
model = AutoModelForMaskedLM.from_pretrained(
"google/bigbird-roberta-base",
torch_dtype=torch.float16,
device_map="auto",
)
inputs = tokenizer("Plants create [MASK] through a process known as photosynthesis.", return_tensors="pt").to("cuda")
with torch.no_grad():
outputs = model(**inputs)
predictions = outputs.logits
masked_index = torch.where(inputs['input_ids'] == tokenizer.mask_token_id)[1]
predicted_token_id = predictions[0, masked_index].argmax(dim=-1)
predicted_token = tokenizer.decode(predicted_token_id)
print(f"The predicted token is: {predicted_token}")
```
</hfoption>
<hfoption id="transformers CLI">
```bash
!echo -e "Plants create [MASK] through a process known as photosynthesis." | transformers-cli run --task fill-mask --model google/bigbird-roberta-base --device 0
```
</hfoption>
</hfoptions>
## Notes
- Inputs should be padded on the right because BigBird uses absolute position embeddings.
- BigBird supports `original_full` and `block_sparse` attention. If the input sequence length is less than 1024, it is recommended to use `original_full` since sparse patterns don't offer much benefit for smaller inputs.
- The current implementation uses window size of 3 blocks and 2 global blocks, only supports the ITC-implementation, and doesn't support `num_random_blocks=0`.
- The sequence length must be divisible by the block size.

## Overview
> [!TIP]
> Click on the BioGPT models in the right sidebar for more examples of how to apply BioGPT to different language tasks.
The BioGPT model was proposed in [BioGPT: generative pre-trained transformer for biomedical text generation and mining](https://academic.oup.com/bib/advance-article/doi/10.1093/bib/bbac409/6713511?guestAccessKey=a66d9b5d-4f83-4017-bb52-405815c907b9) by Renqian Luo, Liai Sun, Yingce Xia, Tao Qin, Sheng Zhang, Hoifung Poon and Tie-Yan Liu. BioGPT is a domain-specific generative pre-trained Transformer language model for biomedical text generation and mining. BioGPT follows the Transformer language model backbone, and is pre-trained on 15M PubMed abstracts from scratch.
The example below demonstrates how to generate biomedical text with [`Pipeline`], [`AutoModel`], and also from the command line.
The abstract from the paper is the following:
<hfoptions id="usage">
<hfoption id="Pipeline">
*Pre-trained language models have attracted increasing attention in the biomedical domain, inspired by their great success in the general natural language domain. Among the two main branches of pre-trained language models in the general language domain, i.e. BERT (and its variants) and GPT (and its variants), the first one has been extensively studied in the biomedical domain, such as BioBERT and PubMedBERT. While they have achieved great success on a variety of discriminative downstream biomedical tasks, the lack of generation ability constrains their application scope. In this paper, we propose BioGPT, a domain-specific generative Transformer language model pre-trained on large-scale biomedical literature. We evaluate BioGPT on six biomedical natural language processing tasks and demonstrate that our model outperforms previous models on most tasks. Especially, we get 44.98%, 38.42% and 40.76% F1 score on BC5CDR, KD-DTI and DDI end-to-end relation extraction tasks, respectively, and 78.2% accuracy on PubMedQA, creating a new record. Our case study on text generation further demonstrates the advantage of BioGPT on biomedical literature to generate fluent descriptions for biomedical terms.*
```py
import torch
from transformers import pipeline
This model was contributed by [kamalkraj](https://huggingface.co/kamalkraj). The original code can be found [here](https://github.com/microsoft/BioGPT).
generator = pipeline(
task="text-generation",
model="microsoft/biogpt",
torch_dtype=torch.float16,
device=0,
)
result = generator("Ibuprofen is best used for", truncation=True, max_length=50, do_sample=True)[0]["generated_text"]
print(result)
## Usage tips
- BioGPT is a model with absolute position embeddings so it's usually advised to pad the inputs on the right rather than the left.
- BioGPT was trained with a causal language modeling (CLM) objective and is therefore powerful at predicting the next token in a sequence. Leveraging this feature allows BioGPT to generate syntactically coherent text as it can be observed in the run_generation.py example script.
- The model can take the `past_key_values` (for PyTorch) as input, which is the previously computed key/value attention pairs. Using this (past_key_values or past) value prevents the model from re-computing pre-computed values in the context of text generation. For PyTorch, see past_key_values argument of the BioGptForCausalLM.forward() method for more information on its usage.
### Using Scaled Dot Product Attention (SDPA)
PyTorch includes a native scaled dot-product attention (SDPA) operator as part of `torch.nn.functional`. This function
encompasses several implementations that can be applied depending on the inputs and the hardware in use. See the
[official documentation](https://pytorch.org/docs/stable/generated/torch.nn.functional.scaled_dot_product_attention.html)
or the [GPU Inference](https://huggingface.co/docs/transformers/main/en/perf_infer_gpu_one#pytorch-scaled-dot-product-attention)
page for more information.
SDPA is used by default for `torch>=2.1.1` when an implementation is available, but you may also set
`attn_implementation="sdpa"` in `from_pretrained()` to explicitly request SDPA to be used.
```
from transformers import BioGptForCausalLM
model = BioGptForCausalLM.from_pretrained("microsoft/biogpt", attn_implementation="sdpa", torch_dtype=torch.float16)

Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
The example below uses [bitsandbytes](../quantization/bitsandbytes) to only quantize the weights to 4-bit precision.
```py
import torch
from transformers import AutoTokenizer, AutoModelForCausalLM, BitsAndBytesConfig
bnb_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_quant_type="nf4",
bnb_4bit_compute_dtype=torch.bfloat16,
bnb_4bit_use_double_quant=True
)
tokenizer = AutoTokenizer.from_pretrained("microsoft/BioGPT-Large")
model = AutoModelForCausalLM.from_pretrained(
"microsoft/BioGPT-Large",
quantization_config=bnb_config,
torch_dtype=torch.bfloat16,
device_map="auto"
)
input_text = "Ibuprofen is best used for"
inputs = tokenizer(input_text, return_tensors="pt").to(model.device)
with torch.no_grad():
generated_ids = model.generate(**inputs, max_length=50)
output = tokenizer.decode(generated_ids[0], skip_special_tokens=True)
print(output)
```
## Notes
- Pad inputs on the right because BioGPT uses absolute position embeddings.
- BioGPT can reuse previously computed key-value attention pairs. Access this feature with the [past_key_values](https://huggingface.co/docs/transformers/main/en/model_doc/biogpt#transformers.BioGptModel.forward.past_key_values) parameter in [`BioGPTModel.forward`].
- The `head_mask` argument is ignored when using an attention implementation other than "eager". If you want to use `head_mask`, make sure `attn_implementation="eager"`).

* **Quantization:** Native 1.58-bit weights and 8-bit activations (W1.58A8).
* Weights are quantized to ternary values {-1, 0, +1} using absmean quantization during the forward pass.
* Activations are quantized to 8-bit integers using absmax quantization (per-token).
* **Crucially, the model was *trained from scratch* with this quantization scheme, not post-training quantized.**
* **Parameters:** ~2 Billion
* **Training Tokens:** 4 Trillion
* **Context Length:** Maximum sequence length of **4096 tokens**.
* *Recommendation:* For optimal performance on tasks requiring very long contexts (beyond the pre-training length or for specialized long-reasoning tasks), we recommend performing intermediate long-sequence adaptation/training before the final fine-tuning stage.
* **Training Stages:**
1. **Pre-training:** Large-scale training on public text/code and synthetic math data using a two-stage learning rate and weight decay schedule.
2. **Supervised Fine-tuning (SFT):** Fine-tuned on instruction-following and conversational datasets using sum loss aggregation and specific hyperparameter tuning.
3. **Direct Preference Optimization (DPO):** Aligned with human preferences using preference pairs.
* **Tokenizer:** LLaMA 3 Tokenizer (vocab size: 128,256).
## Usage tips
**VERY IMPORTANT NOTE ON EFFICIENCY**
> Please do NOT expect performance efficiency gains (in terms of speed, latency, or energy consumption) when using this model with the standard transformers library.
>
> The current execution paths within transformers do not contain the specialized, highly optimized computational kernels required to leverage the advantages of the BitNet architecture. Running the model via transformers will likely result in inference speeds and energy usage comparable to, or potentially worse than, standard full-precision models within this framework on both CPU and GPU.
>
> While you might observe reduced memory usage due to the quantized weights, the primary computational efficiency benefits are not accessible through this standard transformers usage path.
>
> For achieving the efficiency benefits demonstrated in the technical paper, you MUST use the dedicated C++ implementation: [bitnet.cpp](https://github.com/microsoft/BitNet).
### Requirements
```bash
pip install transformers
```
### Example
```python
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer
model_id = "microsoft/bitnet-b1.58-2B-4T"
# Load tokenizer and model
tokenizer = AutoTokenizer.from_pretrained(model_id)
model = AutoModelForCausalLM.from_pretrained(
model_id,
torch_dtype=torch.bfloat16
)
# Apply the chat template
messages = [
{"role": "system", "content": "You are a helpful AI assistant."},
{"role": "user", "content": "How are you?"},
]
chat_input = tokenizer.apply_chat_template(messages, tokenize=True, add_generation_prompt=True, return_tensors="pt").to(model.device)
# Generate response
chat_outputs = model.generate(chat_input, max_new_tokens=50)
response = tokenizer.decode(chat_outputs[0][chat_input.shape[-1]:], skip_special_tokens=True) # Decode only the response part
print("\nAssistant Response:", response)

# ColPali
[ColPali](https://huggingface.co/papers/2407.01449) is a model designed to retrieve documents by analyzing their visual features. Unlike traditional systems that rely heavily on text extraction and OCR, ColPali treats each page as an image. It uses [Paligemma-3B](./paligemma) to capture not only text, but also the layout, tables, charts, and other visual elements to create detailed multi-vector embeddings that can be used for retrieval by computing pairwise late interaction similarity scores. This offers a more comprehensive understanding of documents and enables more efficient and accurate retrieval.

This model was contributed by [@tonywu71](https://huggingface.co/tonywu71) (ILLUIN Technology) and [@yonigozlan](https://huggingface.co/yonigozlan) (HuggingFace).
## Overview
You can find all the original ColPali checkpoints under Vidore's [Hf-native ColVision Models](https://huggingface.co/collections/vidore/hf-native-colvision-models-6755d68fc60a8553acaa96f7) collection.
The *ColPali* model was proposed in [ColPali: Efficient Document Retrieval with Vision Language Models](https://doi.org/10.48550/arXiv.2407.01449) by **Manuel Faysse***, **Hugues Sibille***, **Tony Wu***, Bilel Omrani, Gautier Viaud, Céline Hudelot, Pierre Colombo (* denotes equal contribution). Work lead by ILLUIN Technology.
> [!TIP]
> Click on the ColPali models in the right sidebar for more examples of how to use ColPali for image retrieval.
In our proposed *ColPali* approach, we leverage VLMs to construct efficient multi-vector embeddings directly from document images (“screenshots”) for document retrieval. We train the model to maximize the similarity between these document embeddings and the corresponding query embeddings, using the late interaction method introduced in ColBERT.
<hfoptions id="usage">
<hfoption id="image retrieval">
Using *ColPali* removes the need for potentially complex and brittle layout recognition and OCR pipelines with a single model that can take into account both the textual and visual content (layout, charts, etc.) of a document.

## Usage
This example demonstrates how to use *ColPali* to embed both queries and images, calculate their similarity scores, and identify the most relevant matches. For a specific query, you can retrieve the top-k most similar images by selecting the ones with the highest similarity scores.
```python
import requests
import torch
from PIL import Image
from transformers import ColPaliForRetrieval, ColPaliProcessor
# Load the model and the processor
model_name = "vidore/colpali-v1.3-hf"
model_name = "vidore/colpali-v1.2-hf"
model = ColPaliForRetrieval.from_pretrained(
model_name,
torch_dtype=torch.bfloat16,
device_map="auto", # "cpu", "cuda", or "mps" for Apple Silicon
)
processor = ColPaliProcessor.from_pretrained(model_name)
# The document page screenshots from your corpus
url1 = "https://upload.wikimedia.org/wikipedia/commons/8/89/US-original-Declaration-1776.jpg"
url2 = "https://upload.wikimedia.org/wikipedia/commons/thumb/4/4c/Romeoandjuliet1597.jpg/500px-Romeoandjuliet1597.jpg"
images = [
Image.open(requests.get(url1, stream=True).raw),
Image.open(requests.get(url2, stream=True).raw),
]
# The queries you want to retrieve documents for
queries = [
"When was the United States Declaration of Independence proclaimed?",
"Who printed the edition of Romeo and Juliet?",
]
# Process the inputs
inputs_images = processor(images=images).to(model.device)
inputs_text = processor(text=queries).to(model.device)
# Forward pass
with torch.no_grad():
image_embeddings = model(**inputs_images).embeddings
query_embeddings = model(**inputs_text).embeddings
# Score the queries against the images
scores = processor.score_retrieval(query_embeddings, image_embeddings)
print("Retrieval scores (query x image):")
print(scores)
```
If you have issue with loading the images with PIL, you can use the following code to create dummy images:
```python
images = [
Image.new("RGB", (128, 128), color="white"),
Image.new("RGB", (64, 32), color="black"),
]
```

Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
The example below uses [bitsandbytes](../quantization/bitsandbytes.md) to quantize the weights to int4.
```python
import requests
import torch
from PIL import Image
from transformers import BitsAndBytesConfig, ColPaliForRetrieval, ColPaliProcessor
model_name = "vidore/colpali-v1.3-hf"
# 4-bit quantization configuration
bnb_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_use_double_quant=True,
bnb_4bit_quant_type="nf4",
bnb_4bit_compute_dtype=torch.float16,
)
model = ColPaliForRetrieval.from_pretrained(
model_name,
quantization_config=bnb_config,
device_map="cuda",
)
device_map="cuda:0", # or "mps" if on Apple Silicon
).eval()
processor = ColPaliProcessor.from_pretrained(model_name)
url1 = "https://upload.wikimedia.org/wikipedia/commons/8/89/US-original-Declaration-1776.jpg"
url2 = "https://upload.wikimedia.org/wikipedia/commons/thumb/4/4c/Romeoandjuliet1597.jpg/500px-Romeoandjuliet1597.jpg"
# Your inputs (replace dummy images with screenshots of your documents)
images = [
Image.open(requests.get(url1, stream=True).raw),
Image.open(requests.get(url2, stream=True).raw),
Image.new("RGB", (32, 32), color="white"),
Image.new("RGB", (16, 16), color="black"),
]
queries = [
"When was the United States Declaration of Independence proclaimed?",
"Who printed the edition of Romeo and Juliet?",
"What is the organizational structure for our R&D department?",
"Can you provide a breakdown of last years financial performance?",
]
# Process the inputs
inputs_images = processor(images=images, return_tensors="pt").to(model.device)
inputs_text = processor(text=queries, return_tensors="pt").to(model.device)
batch_images = processor(images=images).to(model.device)
batch_queries = processor(text=queries).to(model.device)
# Forward pass
with torch.no_grad():
image_embeddings = model(**inputs_images).embeddings
query_embeddings = model(**inputs_text).embeddings
image_embeddings = model(**batch_images).embeddings
query_embeddings = model(**batch_queries).embeddings
# Score the queries against the images
scores = processor.score_retrieval(query_embeddings, image_embeddings)
print("Retrieval scores (query x image):")
print(scores)
```
## Notes
- [`~ColPaliProcessor.score_retrieval`] returns a 2D tensor where the first dimension is the number of queries and the second dimension is the number of images. A higher score indicates more similarity between the query and image.

# ColQwen2
[ColQwen2](https://doi.org/10.48550/arXiv.2407.01449) is a variant of the [ColPali](./colpali) model designed to retrieve documents by analyzing their visual features. Unlike traditional systems that rely heavily on text extraction and OCR, ColQwen2 treats each page as an image. It uses the [Qwen2-VL](./qwen2_vl) backbone to capture not only text, but also the layout, tables, charts, and other visual elements to create detailed multi-vector embeddings that can be used for retrieval by computing pairwise late interaction similarity scores. This offers a more comprehensive understanding of documents and enables more efficient and accurate retrieval.
This model was contributed by [@tonywu71](https://huggingface.co/tonywu71) (ILLUIN Technology) and [@yonigozlan](https://huggingface.co/yonigozlan) (HuggingFace).

## Notes
- [`~ColQwen2Processor.score_retrieval`] returns a 2D tensor where the first dimension is the number of queries and the second dimension is the number of images. A higher score indicates more similarity between the query and image.
- Unlike ColPali, ColQwen2 supports arbitrary image resolutions and aspect ratios, which means images are not resized into fixed-size squares. This preserves more of the original input signal.
- Larger input images generate longer multi-vector embeddings, allowing users to adjust image resolution to balance performance and memory usage.
