* Fix typo in LLaVa documentation
In exactly one section, LlavaImageProcessor was spelt wrongly as LLavaImageProcessor, which throws off copy-pasting the section.
* Fix LlavaImageProcessor url to make it valid (and copypaste-able)
Earlier, the URL contained the entire HF prefix. This commit removes that to ensure that the code block can be copied and run as is.

* Update Loss Functions to Accept Tensor num_items_in_batch
* Fix device mismatch by moving num_items_in_batch to loss device in fixed_cross_entropy
* fix the ruff check
* delete the unused if stat
* fix the type problem
transformers.enable_full_determinism enables deterministic
flash attention using `FLASH_ATTENTION_DETERMINISTIC`
800510c67b/src/transformers/trainer_utils.py (L79)
However, current checks use a global variable `deterministic_g`,
which will do the environment variable check as soon as importing,
this will cause issues as users can call
`transformers.enable_full_determinism` after
`transformers.modeling_flash_attention_utils` is imported. This
behavior is introduced in
https://github.com/huggingface/transformers/pull/33932/files#r1806668579
to fix the graph break.
As a result, this PR implement fixes by delaying the environment variable
check to the first time when `_flash_attention_forward` is executed, so
that we can fix this issue and we won't introduce a graph break.

Support tensor-valued _extra_state values
TransformerEngine uses the pytorch get/set_extra_state API to store FP8
layer config information as bytes Tensor in the _extra_state entry in
the state dict. With recent changes to from_pretrained, this
functionality has broken and loading a model that uses this API doesn't
appear to work. This PR fixes the save/load pretrained functions for
extra state entries that use a pytorch tensor, and adds a (currently
x-failing) test for a dictionary extra state.

* docs(swin): Clarify padding description and link to backbone docs
Apply suggestion from @stevhliu in PR #37628.
This change introduces two improvements to the Swin model card:
1. Refines the wording describing how Swin handles input padding for better clarity.
2. Adds an internal documentation link to the general "backbones" page when discussing Swin's capability as a backbone model.
These updates enhance readability and improve navigation within the Transformers documentation.

When preparing the causal attention mask at this point the mask comes
in as a float tensor with min value as a masked value.
It is not correct to convert it to bool and treat it as a bool mask as
this inverts the mask.
`torch.nn.functional.scaled_dot_product_attention` expects that a masked value is `False`.
I suspect that the `sdpa` implementation variant may not have been
thoroughly tested and that is why this error was not caught earlier.

Add Llama4TextModel to AutoModel mapping
using Llama4TextConfig on AutoModel.from_config raises a ValueError when it is expected to instantiate a Llama4TextModel
bnb quant tests: remove obsolete trust_remote_code test
The MPT model is now natively integrated in Transformers and no longer requires trust_remote_code=True. This removes the failing test_get_keys_to_not_convert_trust_remote_code and related usage, which depended on remote code and caused CI issues due to missing dependencies (e.g., triton_pre_mlir).

Summary:
Currently when we try to quantize input_embedding for some models, the output embedding
(lm_head) will also be quantized the same way, since they are tied, and this may not be what
we want. To break the tie, we added the option to allow people to
1. load unquantized weight
2. tie weights
3. quantize
so that the tie will be broken
Test Plan:
```
from transformers import (
AutoModelForCausalLM,
AutoProcessor,
AutoTokenizer,
TorchAoConfig,
)
from torchao.quantization.quant_api import (
IntxWeightOnlyConfig,
Int8DynamicActivationIntxWeightConfig,
AOPerModuleConfig
)
from torchao.quantization.granularity import PerGroup, PerAxis
import torch
model_id = "microsoft/Phi-4-mini-instruct"
embedding_config = IntxWeightOnlyConfig(
weight_dtype=torch.int8,
granularity=PerAxis(0),
)
linear_config = Int8DynamicActivationIntxWeightConfig(
weight_dtype=torch.int4,
weight_granularity=PerGroup(32),
weight_scale_dtype=torch.bfloat16,
)
quant_config = AOPerModuleConfig({"_default": linear_config, "model.embed_tokens": embedding_config})
quantization_config = TorchAoConfig(quant_type=quant_config, include_embedding=True, untie_embedding_weights=True)
quantized_model = AutoModelForCausalLM.from_pretrained(model_id, torch_dtype=torch.float32, device_map="auto", quantization_config=quantization_config)
tokenizer = AutoTokenizer.from_pretrained(model_id)
print(quantized_model)
print("embed_tokens.weight:", quantized_model.model.embed_tokens.weight)
print("lm head weight:", quantized_model.lm_head.weight)
from transformers.modeling_utils import find_tied_parameters
print(find_tied_parameters(quantized_model))

Two PEFT tests are actually failing:
tests/peft_integration/test_peft_integration.py::PeftIntegrationTester::test_delete_adapter
tests/peft_integration/test_peft_integration.py::PeftIntegrationTester::test_peft_pipeline_no_warning
This must have been going on for some time but was apparently never
noticed. The cause is that the tests themselves are faulty, the PEFT
integration is correct in these cases.
test_delete_adapter
The first faulty test was introduced by #34650. AFAICT, it should never
have passed in the first place, the PEFT integration logic was not
changed in the meantime. At this point, the logs for the PR CI are gone,
so I'm not sure if the test passed back then or not.
test_peft_pipeline_no_warning
This test was introduced in #36783 and should also never have passed, as
the self.assertNoLogs context manager only returns None, thus the assert
should never have worked (mea culpa for suggesting this code snippet).
Here too, the CI logs are deleted by now, so I can't check if the test
already failed back then.
* Fix wrong position_ids shape in doc
Supported by ClvpDecoder.forward, line 1212--1215:
src/transformers/models/clvp/modeling_clvp.py:
1212 if inputs_embeds is None:
1213 inputs_embeds = self.input_embeds_layer(input_ids)
1214 position_embeds = self.position_embeds_layer(position_ids)
1215 inputs_embeds = inputs_embeds + position_embeds
* Fix possibly wrong input_ids shape in doc
Since 'input_ids_length' was mentioned immediately after the shape `(batch_size, sequence_length)`, it doesn't make sense to me for `input_ids` to have such shape---IMO it ought to have shape `(batch_size, input_ids_length)` instead.

* fix: Restore explicit error surfacing for unexpected hub exceptions
Prior to PR #36033, unexpected exceptions (e.g., ModuleNotFoundError) during hub model loading were not swallowed silently. They either matched specific except blocks or were raised.
After #36033, a catch-all except Exception block was introduced without a fallback else, causing unknown errors to be silently ignored and leading to misleading downstream behavior.
This commit adds an `else: raise e` to ensure only explicitly handled exceptions are suppressed. All others are surfaced, restoring pre-4.50 behavior and aiding in debugging and dependency visibility.

Corrects the file path used to locate the CUDA kernels
for the Deformable Attention module. This ensures that
the kernels are loaded correctly, resolving potential
errors during module initialization and usage.
Previously, the identity function was used for dropped tokens
with a weight from the expert that was not applied to the hidden states.
This was misleading, because dropping means, the expert weight is zero.
Instead of trying to fix the weight, we take an easier approach by initializing with zeros.

tests: fix asyncio.wait() usage for python>=3.7
Passing coroutings directly to `asyncio.wait()` is deprecated since
python 3.8 and removed starting from python 3.11. Instead, it's required
to explicitly wrap coroutine in the task with `asyncio.create_task()` which
first appeared in python 3.7.
We step into this issue running the following Transformers tests on a
system with python 3.11 or later (for example, Ubuntu 24.04 has python 3.12):
* `tests/trainer/test_trainer_distributed.py`
* `tests/extended/test_trainer_ext.py`
The error will be:
```
src/transformers/testing_utils.py:2380: in execute_subprocess_async
result = loop.run_until_complete(
/usr/lib/python3.12/asyncio/base_events.py:687: in run_until_complete
return future.result()
src/transformers/testing_utils.py:2368: in _stream_subprocess
await asyncio.wait(
...
E TypeError: Passing coroutines is forbidden, use tasks explicitly.

The _fsdp_qlora_plugin_updates checks for LoraConfig but other PEFT
methods can also support quantized models, e.g. VeRA. Therefore, the
isinstance check is now looking for PeftConfig in general.
Moreover, the fsdp_plugin variable may be undefined in the 2nd if
condition, leading to an `UnboundLocalError` error. This is fixed by not
assigning the variable at all.
I checked for tests that may need updating but only found
test_fsdp_config_transformers_auto_wrap associated with this change.
AFAICT, this test does not cover the changed code, since the test does
not start the training loop. Therefore, I haven't updated any tests. LMK
if/how this fix should be tested.

Corrects the type annotation to match actual usage. The variable was typed as
Dict[str, Dict[str, Callable]] but is actually used as Dict[str, Callable]
where keys are attention mechanism names and values are the corresponding
attention functions directly. This change makes the type annotation consistent
with how the dictionary is used in the codebase.

Fixed 2 issues regarding `tests/trainer/test_data_collator.py::TFDataCollatorIntegrationTest::test_all_mask_replacement`:
1. I got the error `RuntimeError: "bernoulli_tensor_cpu_p_" not implemented for 'Long'`. This is because the `mask_replacement_prob=1` and `torch.bernoulli` doesn't accept this type (which would be a `torch.long` dtype instead. I fixed this by manually casting the probability arguments in the `__post_init__` function of `DataCollatorForLanguageModeling`.
2. I also got the error `tensorflow.python.framework.errors_impl.InvalidArgumentError: cannot compute Equal as input #1(zero-based) was expected to be a int64 tensor but is a int32 tensor [Op:Equal]` due to the line `tf.reduce_all((batch["input_ids"] == inputs) | (batch["input_ids"] == tokenizer.mask_token_id))` in `test_data_collator.py`. This occurs because the type of the `inputs` variable is `tf.int32`. Solved this by manually casting it to `tf.int64` in the test, as the expected return type of `batch["input_ids"]` is `tf.int64`.

* fix: prevent model access error during Optuna hyperparameter tuning
The `transformers.integrations.integration_utils.run_hp_search_optuna` function releases model memory and sets trainer.model to None after each trial. This causes an AttributeError when subsequent Trainer.train calls attempt to access the model before reinitialization. This is only an issue when `fp16_full_eval` or `bf16_full_eval` flags are enabled.

* tests: revert change of torch_require_multi_gpu to be device agnostic
The 11c27dd33 modified `torch_require_multi_gpu()` to be device agnostic
instead of being CUDA specific. This broke some tests which are rightfully
CUDA specific, such as:
* `tests/trainer/test_trainer_distributed.py::TestTrainerDistributed`
In the current Transformers tests architecture `require_torch_multi_accelerator()`
should be used to mark multi-GPU tests agnostic to device.
This change addresses the issue introduced by 11c27dd33 and reverts
modification of `torch_require_multi_gpu()`.
Fixes: 11c27dd33 ("Enable BNB multi-backend support (#31098)")

The original regex pattern in tokenization_nougat_fast.py was vulnerable to

2. Handles whitespace more precisely

* Add dithering to the `Speech2TextFeatureExtractor` API.
- in kaldi : 4a8b7f6732/src/feat/feature-window.cc (L145)
- with dithering without a seed, the features become non-deterministic due
to small Gaussian noise added to the audio (i.e. 2 runs lead to little
different outputs)
* update the PR
- add dithering also for WhisperFeatureExtractor
- not adding to Wav2Vec2FeatureExtractor (no FBANK computation)

* Fix XGLM loss computation (PyTorch and TensorFlow)
* Update expected output string in XGLM sample test
This updates the expected output string of test_xglm_sample for torch
2.0 to the correct one and removes the one for torch 1.13.1 + cu116
(transformers moved to torch 2.0 with PR #35358).
* Update expected output IDs in XGLM generation test
**Summary:** TorchAoConfig optionally contains a
`torchao.dtypes.Layout` object which is a dataclass and not
JSON serializable, and so the following fails:
```
import json
from torchao.dtypes import TensorCoreTiledLayout
from transformers import TorchAoConfig
config = TorchAoConfig("int4_weight_only", layout=TensorCoreTiledLayout())
config.to_json_string()
json.dumps(config.to_dict())
```
This also causes `quantized_model.save_pretrained(...)` to
fail because the first step of this call is to JSON serialize
the config. Fixes https://github.com/pytorch/ao/issues/1704.
**Test Plan:**
python tests/quantization/torchao_integration/test_torchao.py -k test_json_serializable

🤗 Transformers provides thousands of pretrained models to perform tasks on different modalities such as text, vision, and audio.
Transformers is a library of pretrained text, computer vision, audio, video, and multimodal models for inference and training. Use Transformers to fine-tune models on your data, build inference applications, and for generative AI use cases across multiple modalities.
These models can be applied on:
There are over 500K+ Transformers [model checkpoints](https://huggingface.co/models?library=transformers&sort=trending) on the [Hugging Face Hub](https://huggingface.com/models) you can use.
* 📝 Text, for tasks like text classification, information extraction, question answering, summarization, translation, and text generation, in over 100 languages.
* 🖼️ Images, for tasks like image classification, object detection, and segmentation.
* 🗣️ Audio, for tasks like speech recognition and audio classification.
Explore the [Hub](https://huggingface.com/) today to find a model and use Transformers to help you get started right away.
Transformer models can also perform tasks on **several modalities combined**, such as table question answering, optical character recognition, information extraction from scanned documents, video classification, and visual question answering.
## Installation
🤗 Transformers provides APIs to quickly download and use those pretrained models on a given text, fine-tune them on your own datasets and then share them with the community on our [model hub](https://huggingface.co/models). At the same time, each python module defining an architecture is fully standalone and can be modified to enable quick research experiments.
Transformers works with Python 3.9+ [PyTorch](https://pytorch.org/get-started/locally/) 2.1+, [TensorFlow](https://www.tensorflow.org/install/pip) 2.6+, and [Flax](https://flax.readthedocs.io/en/latest/) 0.4.1+.
🤗 Transformers is backed by the three most popular deep learning libraries — [Jax](https://jax.readthedocs.io/en/latest/), [PyTorch](https://pytorch.org/) and [TensorFlow](https://www.tensorflow.org/) — with a seamless integration between them. It's straightforward to train your models withone before loading them for inference with the other.
Create and activate a virtual environment with [venv](https://docs.python.org/3/library/venv.html) or [uv](https://docs.astral.sh/uv/), a fast Rust-based Python package and project manager.
## Online demos
You can test most of our models directly on their pages from the [model hub](https://huggingface.co/models). We also offer [private model hosting, versioning, & an inference API](https://huggingface.co/pricing) for public and private models.

## 100 projects using Transformers
Transformers is more than a toolkit to use pretrained models: it's a community of projects built around it and the
Hugging Face Hub. We want Transformers to enable developers, researchers, students, professors, engineers, and anyone
else to build their dream projects.
In order to celebrate the 100,000 stars of transformers, we have decided to put the spotlight on the
community, and we have created the [awesome-transformers](./awesome-transformers.md) page which lists 100
incredible projects built in the vicinity of transformers.
If you own or use a project that you believe should be part of the list, please open a PR to add it!

## Quick tour
To immediately use a model on a given input (text, image, audio, ...), we provide the `pipeline` API. Pipelines group together a pretrained model with the preprocessing that was used during that model's training. Here is how to quickly use a pipeline to classify positive versus negative texts:
```python
>>>fromtransformersimportpipeline
# Allocate a pipeline for sentiment-analysis
>>>classifier=pipeline('sentiment-analysis')
>>>classifier('We are very happy to introduce pipeline to the transformers repository.')
[{'label':'POSITIVE','score':0.9996980428695679}]
```py
# venv
python-mvenv.my-env
source.my-env/bin/activate
# uv
uvvenv.my-env
source.my-env/bin/activate
```
The second line of code downloads and caches the pretrained model used by the pipeline, while the third evaluates it on the given text. Here, the answer is "positive" with a confidence of 99.97%.
Install Transformers in your virtual environment.
Many tasks have a pre-trained `pipeline` ready to go, in NLP but also in computer vision and speech. For example, we can easily extract detected objects in an image:
Here, we get a list of objects detected in the image, with a box surrounding the object and a confidence score. Here is the original image on the left, with the predictions displayed on the right:
Install Transformers from source if you want the latest changes in the library or are interested in contributing. However, the *latest* version may not be stable. Feel free to open an [issue](https://github.com/huggingface/transformers/issues) if you encounter an error.
Get started with Transformers right away with the [Pipeline](https://huggingface.co/docs/transformers/pipeline_tutorial) API. The `Pipeline` is a high-level inference class that supports text, audio, vision, and multimodal tasks. It handles preprocessing the input and returns the appropriate output.
Instantiate a pipeline and specify model to use for text generation. The model is downloaded and cached so you can easily reuse it again. Finally, pass some text to prompt the model.
pipeline("the secret to baking a really good cake is ")
[{'generated_text':'the secret to baking a really good cake is 1) to use the right ingredients and 2) to follow the recipe exactly. the recipe for the cake is as follows: 1 cup of sugar, 1 cup of flour, 1 cup of milk, 1 cup of butter, 1 cup of eggs, 1 cup of chocolate chips. if you want to make 2 cakes, how much sugar do you need? To make 2 cakes, you will need 2 cups of sugar.'}]
```
To chat with a model, the usage pattern is the same. The only difference is you need to construct a chat history (the input to `Pipeline`) between you and the system.
> [!TIP]
> You can also chat with a model directly from the command line.
> ```shell
> transformers chat Qwen/Qwen2.5-0.5B-Instruct
> ```
```py
importtorch
fromtransformersimportpipeline
chat=[
{"role":"system","content":"You are a sassy, wise-cracking robot as imagined by Hollywood circa 1986."},
{"role":"user","content":"Hey, can you tell me any fun things to do in New York?"}
You can learn more about the tasks supported by the `pipeline` API in [this tutorial](https://huggingface.co/docs/transformers/task_summary).
```py
fromtransformersimportpipeline
In addition to `pipeline`, to download and use any of the pretrained models on your given task, all it takes is three lines of code. Here is the PyTorch version:
```python
>>> from transformers import AutoTokenizer, AutoModel
The tokenizer is responsible for all the preprocessing the pretrained model expects and can be called directly on a single string (as in the above examples) or a list. It will output a dictionary that you can use in downstream code or simply directly pass to your model using the ** argument unpacking operator.
</details>
The model itself is a regular [Pytorch `nn.Module`](https://pytorch.org/docs/stable/nn.html#torch.nn.Module) or a [TensorFlow `tf.keras.Model`](https://www.tensorflow.org/api_docs/python/tf/keras/Model) (depending on your backend) which you can use as usual. [This tutorial](https://huggingface.co/docs/transformers/training) explains how to integrate such a model into a classic PyTorch or TensorFlow training loop, or how to use our `Trainer` API to quickly fine-tune on a new dataset.
## Why should I use transformers?

</a><br>
## Why shouldn't I use Transformers?
- This library is not a modular toolbox of building blocks for neural nets. The code in the model files is not refactored with additional abstractions on purpose, so that researchers can quickly iterate on each of the models without diving into additional abstractions/files.
- The training API is not intended to work on any model but is optimized to work with the models provided by the library. For generic machine learning loops, you should use another library (possibly, [Accelerate](https://huggingface.co/docs/accelerate)).
- While we strive to present as many use cases as possible, the scripts in our [examples folder](https://github.com/huggingface/transformers/tree/main/examples) are just that: examples. It is expected that they won't work out-of-the-box on your specific problem and that you will be required to change a few lines of code to adapt them to your needs.

In this folder you will find various docker files, and some subfolders.
- dockerfiles (ex: `consistency.dockerfile`) present under `~/docker` are used for our "fast" CIs. You should be able to use them for tasks that only need CPU. For example `torch-light` is a very light weights container (703MiB).
- subfloder contain dockerfiles used for our `slow` CIs, which *can* be used for GPU tasks, but they are **BIG** as they were not specifically designed for a single model / single task. Thus the `~/docker/transformers-pytorch-gpu` includes additional dependencies to allow us to run ALL model tests (say `librosa` or `tesseract`, which you do not need to run LLMs)

Note that in both case, you need to run `uv pip install -e .`, which should take around 5 seconds. We do it outside the dockerfile for the need of our CI: we checkout a new branch each time, and the `transformers` code is thus updated.

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.

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?",
- 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.
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.
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`]:
>>>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 shold 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 acces 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`.
> 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
fromtransformersimportload_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.
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
fromtransformersimportTool
fromhuggingface_hubimportlist_models
classHFModelDownloadsTool(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)",
الآن بعد أن أصبحت فئة `HfModelDownloadsTool` المخصصة جاهزة، يمكنك حفظها في ملف باسم `model_downloads.py` واستيرادها للاستخدام.
```python
frommodel_downloadsimportHFModelDownloadsTool
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.
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.
> 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!
[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`:
> 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.
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:
- الوصول إلى جميع أوزان الانتباه لكل رأس في BERT/GPT/GPT-2،
- استرجاع قيم ومشتقات مخرجات الرأس لحساب درجة أهمية الرأس وحذفه كما هو موضح في https://arxiv.org/abs/1905.10650.

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")
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
fromtransformersimportload_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)

# Distributed training with 🤗 Accelerate
# Accelerate
As models get bigger, parallelism has emerged as a strategy for training larger models on limited hardware and accelerating training speed by several orders of magnitude. At Hugging Face, we created the [🤗 Accelerate](https://huggingface.co/docs/accelerate) library to help users easily train a 🤗 Transformers model on any type of distributed setup, whether it is multiple GPU's on one machine or multiple GPU's across several machines. In this tutorial, learn how to customize your native PyTorch training loop to enable training in a distributed environment.
[Accelerate](https://hf.co/docs/accelerate/index) is a library designed to simplify distributed training on any type of setup with PyTorch by uniting the most common frameworks ([Fully Sharded Data Parallel (FSDP)](https://pytorch.org/blog/introducing-pytorch-fully-sharded-data-parallel-api/) and [DeepSpeed](https://www.deepspeed.ai/)) for it into a single interface. [`Trainer`] is powered by Accelerate under the hood, enabling loading big models and distributed training.
## Setup
Get started by installing 🤗 Accelerate:
This guide will show you two ways to use Accelerate with Transformers, using FSDP as the backend. The first method demonstrates distributed training with [`Trainer`], and the second method demonstrates adapting a PyTorch training loop. For more detailed information about Accelerate, please refer to the [documentation](https://hf.co/docs/accelerate/index).
```bash
pip install accelerate
```
Then import and create an [`~accelerate.Accelerator`] object. The [`~accelerate.Accelerator`] will automatically detect your type of distributed setup and initialize all the necessary components for training. You don't need to explicitly place your model on a device.
```py
>>>fromaccelerateimportAccelerator
>>>accelerator=Accelerator()
```
## Prepare to accelerate
The next step is to pass all the relevant training objects to the [`~accelerate.Accelerator.prepare`] method. This includes your training and evaluation DataLoaders, a model and an optimizer:
- batch = {k: v.to(device) for k, v in batch.items()}
outputs = model(**batch)
loss = outputs.loss
- loss.backward()
+ accelerator.backward(loss)
optimizer.step()
lr_scheduler.step()
optimizer.zero_grad()
progress_bar.update(1)
```
## Train
Once you've added the relevant lines of code, launch your training in a script or a notebook like Colaboratory.
### Train with a script
If you are running your training from a script, run the following command to create and save a configuration file:
Start by running [accelerate config](https://hf.co/docs/accelerate/main/en/package_reference/cli#accelerate-config) in the command line to answer a series of prompts about your training system. This creates and saves a configuration file to help Accelerate correctly set up training based on your setup.
```bash
accelerate config
```
Then launch your training with:
Depending on your setup and the answers you provide, an example configuration file for distributing training with FSDP on one machine with two GPUs may look like the following.
```bash
accelerate launch train.py
```yaml
compute_environment:LOCAL_MACHINE
debug:false
distributed_type:FSDP
downcast_bf16:'no'
fsdp_config:
fsdp_auto_wrap_policy:TRANSFORMER_BASED_WRAP
fsdp_backward_prefetch_policy:BACKWARD_PRE
fsdp_forward_prefetch:false
fsdp_cpu_ram_efficient_loading:true
fsdp_offload_params:false
fsdp_sharding_strategy:FULL_SHARD
fsdp_state_dict_type:SHARDED_STATE_DICT
fsdp_sync_module_states:true
fsdp_transformer_layer_cls_to_wrap:BertLayer
fsdp_use_orig_params:true
machine_rank:0
main_training_function:main
mixed_precision:bf16
num_machines:1
num_processes:2
rdzv_backend:static
same_network:true
tpu_env:[]
tpu_use_cluster:false
tpu_use_sudo:false
use_cpu:false
```
### Train with a notebook
## Trainer
🤗 Accelerate can also run in a notebook if you're planning on using Colaboratory's TPUs. Wrap all the code responsible for training in a function, and pass it to [`~accelerate.notebook_launcher`]:
Pass the path to the saved configuration file to [`TrainingArguments`], and from there, pass your [`TrainingArguments`] to [`Trainer`].
```py
>>>fromaccelerateimportnotebook_launcher
fromtransformersimportTrainingArguments,Trainer
>>>notebook_launcher(training_function)
training_args=TrainingArguments(
output_dir="your-model",
learning_rate=2e-5,
per_device_train_batch_size=16,
per_device_eval_batch_size=16,
num_train_epochs=2,
fsdp_config="path/to/fsdp_config",
fsdp_strategy="full_shard",
weight_decay=0.01,
eval_strategy="epoch",
save_strategy="epoch",
load_best_model_at_end=True,
push_to_hub=True,
)
trainer=Trainer(
model=model,
args=training_args,
train_dataset=dataset["train"],
eval_dataset=dataset["test"],
processing_class=tokenizer,
data_collator=data_collator,
compute_metrics=compute_metrics,
)
trainer.train()
```
For more information about 🤗 Accelerate and its rich features, refer to the [documentation](https://huggingface.co/docs/accelerate).
## Native PyTorch
Accelerate can also be added to any PyTorch training loop to enable distributed training. The [`~accelerate.Accelerator`] is the main entry point for adapting your PyTorch code to work with Accelerate. It automatically detects your distributed training setup and initializes all the necessary components for training. You don't need to explicitly place your model on a device because [`~accelerate.Accelerator`] knows which device to move your model to.
```py
fromaccelerateimportAccelerator
accelerator=Accelerator()
device=accelerator.device
```
All PyTorch objects (model, optimizer, scheduler, dataloaders) should be passed to the [`~accelerate.Accelerator.prepare`] method now. This method moves your model to the appropriate device or devices, adapts the optimizer and scheduler to use [`~accelerate.optimizer.AcceleratedOptimizer`] and [`~accelerate.scheduler.AcceleratedScheduler`], and creates a new shardable dataloader.
Replace `loss.backward` in your training loop with Accelerates [`~accelerate.Accelerator.backward`] method to scale the gradients and determine the appropriate `backward` method to use depending on your framework (for example, DeepSpeed or Megatron).
```py
forepochinrange(num_epochs):
forbatchintrain_dataloader:
outputs=model(**batch)
loss=outputs.loss
accelerator.backward(loss)
optimizer.step()
lr_scheduler.step()
optimizer.zero_grad()
progress_bar.update(1)
```
Combine everything into a function and make it callable as a script.
From the command line, call [accelerate launch](https://hf.co/docs/accelerate/main/en/package_reference/cli#accelerate-launch) to run your training script. Any additional arguments or parameters can be passed here as well.
To launch your training script on two GPUs, add the `--num_processes` argument.

# 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.
<hfoptionsid="select-accelerator">
<hfoptionid="torchrun">
Use the `--nproc_per_node` to select how many accelerators to use.
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:
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.

# How to create a custom pipeline?
# Adding a new pipeline
In this guide, we will see how to create a custom pipeline and share it on the [Hub](https://hf.co/models) or add it to the
🤗 Transformers library.
Make [`Pipeline`] your own by subclassing it and implementing a few methods. Share the code with the community on the [Hub](https://hf.co) and register the pipeline with Transformers so that everyone can quickly and easily use it.
First and foremost, you need to decide the raw entries the pipeline will be able to take. It can be strings, raw bytes,
dictionaries or whatever seems to be the most likely desired input. Try to keep these inputs as pure Python as possible
as it makes compatibility easier (even through other languages via JSON). Those will be the `inputs` of the
pipeline (`preprocess`).
This guide will walk you through the process of adding a new pipeline to Transformers.
Then define the `outputs`. Same policy as the `inputs`. The simpler, the better. Those will be the outputs of
`postprocess` method.
## Design choices
Start by inheriting the base class `Pipeline` with the 4 methods needed to implement `preprocess`,
`_forward`, `postprocess`, and `_sanitize_parameters`.
At a minimum, you only need to provide [`Pipeline`] with an appropriate input for a task. This is also where you should begin when designing your pipeline.
Decide what input types [`Pipeline`] can accept. It can be strings, raw bytes, dictionaries, and so on. Try to keep the inputs in pure Python where possible because it's more compatible. Next, decide on the output [`Pipeline`] should return. Again, keeping the output in Python is the simplest and best option because it's easier to work with.
```python
Keeping the inputs and outputs simple, and ideally JSON-serializable, makes it easier for users to run your [`Pipeline`] without needing to learn new object types. It's also common to support many different input types for even greater ease of use. For example, making an audio file acceptable from a filename, URL, or raw bytes gives the user more flexibility in how they provide the audio data.
## Create a pipeline
With an input and output decided, you can start implementing [`Pipeline`]. Your pipeline should inherit from the base [`Pipeline`] class and include 4 methods.
In order to achieve that, we'll update our `postprocess` method with a default parameter to `5`. and edit
`_sanitize_parameters` to allow this new parameter.
2.`_forward` shouldn't be called directly. `forward` is the preferred method because it includes safeguards to make sure everything works correctly on the expected device. Anything linked to the model belongs in `_forward` and everything else belongs in either `preprocess` or `postprocess`.
```py
def_forward(self,model_inputs):
outputs=self.model(**model_inputs)
returnoutputs
```
```python
3.`postprocess` generates the final output from the models output in `_forward`.
```py
defpostprocess(self,model_outputs,top_k=5):
best_class=model_outputs["logits"].softmax(-1)
# Add logic to handle top_k
returnbest_class
```
4.`_sanitize_parameters` lets users pass additional parameters to [`Pipeline`]. This could be during initialization or when [`Pipeline`] is called. `_sanitize_parameters` returns 3 dicts of additional keyword arguments that are passed directly to `preprocess`, `_forward`, and `postprocess`. Don't add anything if a user didn't call the pipeline with extra parameters. This keeps the default arguments in the function definition which is always more natural.
For example, add a `top_k` parameter in `postprocess` to return the top 5 most likely classes. Then in `_sanitize_parameters`, check if the user passed in `top_k` and add it to `postprocess_kwargs`.
You can specify a default model if you want, in which case it should come with a specific revision (which can be the name of a branch or a commit hash, here we took `"abcdef"`) as well as the type:
## Share your pipeline
```python
PIPELINE_REGISTRY.register_pipeline(
"new-task",
pipeline_class=MyPipeline,
pt_model=AutoModelForSequenceClassification,
default={"pt":("user/awesome_model","abcdef")},
type="text",# current support type: text, audio, image, multimodal
)
```
Share your pipeline with the community on the [Hub](https://hf.co) or you can add it directly to Transformers.
## Share your pipeline on the Hub
It's faster to upload your pipeline code to the Hub because it doesn't require a review from the Transformers team. Adding the pipeline to Transformers may be slower because it requires a review and you need to add tests to ensure your [`Pipeline`] works.
To share your custom pipeline on the Hub, you just have to save the custom code of your `Pipeline` subclass in a
python file. For instance, let's say we want to use a custom pipeline for sentence pair classification like this:
### Upload to the Hub
Add your pipeline code to the Hub in a Python file.
For example, a custom pipeline for sentence pair classification might look like the following code below. The implementation works for PyTorch and TensorFlow models.
@ -215,56 +194,36 @@ The [register_pipeline](https://github.com/huggingface/transformers/blob/9feae5f
},
```
Once this is done, we can use it with a pretrained model. For instance `sgugger/finetuned-bert-mrpc` has been
fine-tuned on the MRPC dataset, which classifies pairs of sentences as paraphrases or not.
Call [`~Pipeline.push_to_hub`] to push the pipeline to the Hub. The Python file containing the code is copied to the Hub, and the pipelines model and tokenizer are also saved and pushed to the Hub. Your pipeline should now be available on the Hub under your namespace.
If you want to contribute your pipeline to 🤗 Transformers, you will need to add a new module in the `pipelines` submodule
with the code of your pipeline, then add it to the list of tasks defined in `pipelines/__init__.py`.
Adding a custom pipeline to Transformers requires adding tests to make sure everything works as expected, and requesting a review from the Transformers team.
Then you will need to add tests. Create a new file `tests/test_pipelines_MY_PIPELINE.py` with examples of the other tests.
Add your pipeline code as a new module to the [pipelines](https://github.com/huggingface/transformers/tree/main/src/transformers/pipelines) submodule, and add it to the list of tasks defined in [pipelines/__init__.py](https://github.com/huggingface/transformers/blob/main/src/transformers/pipelines/__init__.py).
The `run_pipeline_test` function will be very generic and run on small random models on every possible
architecture as defined by `model_mapping` and `tf_model_mapping`.
Next, add a new test for the pipeline in [transformers/tests/pipelines](https://github.com/huggingface/transformers/tree/main/tests/pipelines). You can look at the other tests for examples of how to test your pipeline.
This is very important to test future compatibility, meaning if someone adds a new model for
`XXXForQuestionAnswering` then the pipeline test will attempt to run on it. Because the models are random it's
impossible to check for actual values, that's why there is a helper `ANY` that will simply attempt to match the
output of the pipeline TYPE.
The [run_pipeline_test](https://github.com/huggingface/transformers/blob/db70426854fe7850f2c5834d633aff637f14772e/tests/pipelines/test_pipelines_text_classification.py#L186) function should be very generic and run on the models defined in [model_mapping](https://github.com/huggingface/transformers/blob/db70426854fe7850f2c5834d633aff637f14772e/tests/pipelines/test_pipelines_text_classification.py#L48) and [tf_model_mapping](https://github.com/huggingface/transformers/blob/db70426854fe7850f2c5834d633aff637f14772e/tests/pipelines/test_pipelines_text_classification.py#L49). This is important for testing future compatibility with new models.
You also *need* to implement 2 (ideally 4) tests.
You'll also notice `ANY` is used throughout the [run_pipeline_test](https://github.com/huggingface/transformers/blob/db70426854fe7850f2c5834d633aff637f14772e/tests/pipelines/test_pipelines_text_classification.py#L186) function. The models are random, so you can't check the actual values. Using `ANY` allows the test to match the output of the pipeline type instead.
-`test_small_model_pt` : Define 1 small model for this pipeline (doesn't matter if the results don't make sense)
and test the pipeline outputs. The results should be the same as `test_small_model_tf`.
-`test_small_model_tf` : Define 1 small model for this pipeline (doesn't matter if the results don't make sense)
and test the pipeline outputs. The results should be the same as `test_small_model_pt`.
-`test_large_model_pt` (`optional`): Tests the pipeline on a real pipeline where the results are supposed to
make sense. These tests are slow and should be marked as such. Here the goal is to showcase the pipeline and to make
sure there is no drift in future releases.
-`test_large_model_tf` (`optional`): Tests the pipeline on a real pipeline where the results are supposed to
make sense. These tests are slow and should be marked as such. Here the goal is to showcase the pipeline and to make
sure there is no drift in future releases.
Finally, you should also implement the following 4 tests.
1. [test_small_model_pt](https://github.com/huggingface/transformers/blob/db70426854fe7850f2c5834d633aff637f14772e/tests/pipelines/test_pipelines_text_classification.py#L59) and [test_small_model_tf](https://github.com/huggingface/transformers/blob/db70426854fe7850f2c5834d633aff637f14772e/tests/pipelines/test_pipelines_text_classification.py#L150), use a small model for these pipelines to make sure they return the correct outputs. The results don't have to make sense. Each pipeline should return the same result.
1. [test_large_model_pt](https://github.com/huggingface/transformers/blob/db70426854fe7850f2c5834d633aff637f14772e/tests/pipelines/test_pipelines_zero_shot_image_classification.py#L187) nad [test_large_model_tf](https://github.com/huggingface/transformers/blob/db70426854fe7850f2c5834d633aff637f14772e/tests/pipelines/test_pipelines_zero_shot_image_classification.py#L220), use a realistic model for these pipelines to make sure they return meaningful results. These tests are slow and should be marked as slow.

# Agents and tools
[[open-in-colab]]
### What is an agent?
Large Language Models (LLMs) trained to perform [causal language modeling](./tasks/language_modeling) can tackle a wide range of tasks, but they often struggle with basic tasks like logic, calculation, and search. When prompted in domains in which they do not perform well, they often fail to generate the answer we expect them to.
One approach to overcome this weakness is to create an *agent*.
An agent is a system that uses an LLM as its engine, and it has access to functions called *tools*.
These *tools* are functions for performing a task, and they contain all necessary description for the agent to properly use them.
The agent can be programmed to:
- devise a series of actions/tools and run them all at once, like the [`CodeAgent`]
- plan and execute actions/tools one by one and wait for the outcome of each action before launching the next one, like the [`ReactJsonAgent`]
### Types of agents
#### Code agent
This agent has a planning step, then generates python code to execute all its actions at once. It natively handles different input and output types for its tools, thus it is the recommended choice for multimodal tasks.
#### React agents
This is the go-to agent to solve reasoning tasks, since the ReAct framework ([Yao et al., 2022](https://huggingface.co/papers/2210.03629)) makes it really efficient to think on the basis of its previous observations.
We implement two versions of ReactJsonAgent:
- [`ReactJsonAgent`] generates tool calls as a JSON in its output.
- [`ReactCodeAgent`] is a new type of ReactJsonAgent that generates its tool calls as blobs of code, which works really well for LLMs that have strong coding performance.
> [!TIP]
> Read [Open-source LLMs as LangChain Agents](https://huggingface.co/blog/open-source-llms-as-agents) blog post to learn more about ReAct agents.
- an LLM to power your agent - the agent is not exactly the LLM, it’s more like the agent is a program that uses an LLM as its engine.
- a system prompt: what the LLM engine will be prompted with to generate its output
- a toolbox from which the agent pick tools to execute
- a parser to extract from the LLM output which tools are to call and with which arguments
Upon initialization of the agent system, the tool attributes are used to generate a tool description, then baked into the agent’s `system_prompt` to let it know which tools it can use and why.
To start with, please install the `agents` extras in order to install all default dependencies.
```bash
pip install transformers[agents]
```
Build your LLM engine by defining a `llm_engine` method which accepts a list of [messages](./chat_templating) and returns text. This callable also needs to accept a `stop` argument that indicates when to stop generating.
1. it follows the [messages format](./chat_templating) (`List[Dict[str, str]]`) for its input `messages`, and it returns a `str`.
2. it stops generating outputs at the sequences passed in the argument `stop_sequences`
Additionally, `llm_engine` can also take a `grammar` argument. In the case where you specify a `grammar` upon agent initialization, this argument will be passed to the calls to llm_engine, with the `grammar` that you defined upon initialization, to allow [constrained generation](https://huggingface.co/docs/text-generation-inference/conceptual/guidance) in order to force properly-formatted agent outputs.
You will also need a `tools` argument which accepts a list of `Tools` - it can be an empty list. You can also add the default toolbox on top of your `tools` list by defining the optional argument `add_base_tools=True`.
Now you can create an agent, like [`CodeAgent`], and run it. You can also create a [`TransformersEngine`] with a pre-initialized pipeline to run inference on your local machine using `transformers`.
For convenience, since agentic behaviours generally require stronger models such as `Llama-3.1-70B-Instruct` that are harder to run locally for now, we also provide the [`HfApiEngine`] class that initializes a `huggingface_hub.InferenceClient` under the hood.
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")
```
The prompt and output parser were automatically defined, but you can easily inspect them by calling the `system_prompt_template` on your agent.
```python
print(agent.system_prompt_template)
```
It's important to explain as clearly as possible the task you want to perform.
Every [`~Agent.run`] operation is independent, and since an agent is powered by an LLM, minor variations in your prompt might yield completely different results.
You can also run an agent consecutively for different tasks: each time the attributes `agent.task` and `agent.logs` will be re-initialized.
#### Code execution
A Python interpreter executes the code on a set of inputs passed along with your tools.
This should be safe because the only functions that can be called are the tools you provided (especially if it's only tools by Hugging Face) and the print function, so you're already limited in what can be executed.
The Python interpreter also doesn't allow imports by default outside of a safe list, so all the most obvious attacks shouldn't be an issue.
You can still authorize additional imports by passing the authorized modules as a list of strings in argument `additional_authorized_imports` upon initialization of your [`ReactCodeAgent`] or [`CodeAgent`]:
>>>agent.run("Could you get me the title of the page at url 'https://huggingface.co/blog'?")
(...)
'Hugging Face – Blog'
```
The execution will stop at any code trying to perform an illegal operation or if there is a regular Python error with the code generated by the agent.
> [!WARNING]
> The LLM can generate arbitrary code that will then be executed: do not add any unsafe imports!
### The system prompt
An agent, or rather the LLM that drives the agent, generates an output based on the system prompt. The system prompt can be customized and tailored to the intended task. For example, check the system prompt for the [`ReactCodeAgent`] (below version is slightly simplified).
```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 acces 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 includes:
- An *introduction* that explains how the agent should behave and what tools are.
- A description of all the tools that is defined by a `<<tool_descriptions>>` token that is dynamically replaced at runtime with the tools defined/chosen by the user.
- The tool description comes from the tool attributes, `name`, `description`, `inputs` and `output_type`, and a simple `jinja2` template that you can refine.
- The expected output format.
You could improve the system prompt, for example, by adding an explanation of the output format.
For maximum flexibility, you can overwrite the whole system prompt template by passing your custom prompt as an argument to the `system_prompt` parameter.
> Please make sure to define the `<<tool_descriptions>>` string somewhere in the `template` so the agent is aware
of the available tools.
### Inspecting an agent run
Here are a few useful attributes to inspect what happened after a run:
-`agent.logs` stores the fine-grained logs of the agent. At every step of the agent's run, everything gets stored in a dictionary that then is appended to `agent.logs`.
- Running `agent.write_inner_memory_from_logs()` creates an inner memory of the agent's logs for the LLM to view, as a list of chat messages. This method goes over each step of the log and only stores what it's interested in as a message: for instance, it will save the system prompt and task in separate messages, then for each step it will store the LLM output as a message, and the tool call output as another message. Use this if you want a higher-level view of what has happened - but not every log will be transcripted by this method.
## Tools
A tool is an atomic function to be used by an agent.
You can for instance check the [`PythonInterpreterTool`]: it has a name, a description, input descriptions, an output type, and a `__call__` method to perform the action.
When the agent is initialized, the tool attributes are used to generate a tool description which is baked into the agent's system prompt. This lets the agent know which tools it can use and why.
### Default toolbox
Transformers comes with a default toolbox for empowering agents, that you can add to your agent upon initialization with argument `add_base_tools = True`:
- **Document question answering**: given a document (such as a PDF) in image format, answer a question on this document ([Donut](./model_doc/donut))
- **Image question answering**: given an image, answer a question on this image ([VILT](./model_doc/vilt))
- **Speech to text**: given an audio recording of a person talking, transcribe the speech into text ([Whisper](./model_doc/whisper))
- **Text to speech**: convert text to speech ([SpeechT5](./model_doc/speecht5))
- **Translation**: translates a given sentence from source language to target language.
- **DuckDuckGo search***: performs a web search using DuckDuckGo browser.
- **Python code interpreter**: runs your the LLM generated Python code in a secure environment. This tool will only be added to [`ReactJsonAgent`] if you initialize it with `add_base_tools=True`, since code-based agent can already natively execute Python code
You can manually use a tool by calling the [`load_tool`] function and a task to perform.
```python
fromtransformersimportload_tool
tool=load_tool("text-to-speech")
audio=tool("This is a text to speech tool")
```
### Create a new tool
You can create your own tool for use cases not covered by the default tools from Hugging Face.
For example, let's create a tool that returns the most downloaded model for a given task from the Hub.
- A clear name. The name usually describes what the tool does. Since the code returns the model with the most downloads for a task, let's put `model_download_tool`.
- Type hints on both inputs and output
- A description, that includes an 'Args:' part where each argument is described (without a type indication this time, it will be pulled from the type hint).
All these will be automatically baked into the agent's system prompt upon initialization: so strive to make them as clear as possible!
> [!TIP]
> This definition format is the same as tool schemas used in `apply_chat_template`, the only difference is the added `tool` decorator: read more on our tool use API [here](https://huggingface.co/blog/unified-tool-use#passing-tools-to-a-chat-template).
print(f"The most downloaded model for the 'text-to-video' task is {most_downloaded_model}.")
====
```
And the output:
`"The most downloaded model for the 'text-to-video' task is ByteDance/AnimateDiff-Lightning."`
### Manage your agent's toolbox
If you have already initialized an agent, it is inconvenient to reinitialize it from scratch with a tool you want to use. With Transformers, you can manage an agent's toolbox by adding or replacing a tool.
Let's add the `model_download_tool` to an existing agent initialized with only the default toolbox.
> Beware when adding tools to an agent that already works well because it can bias selection towards your tool or select another tool other than the one already defined.
Use the `agent.toolbox.update_tool()` method to replace an existing tool in the agent's toolbox.
This is useful if your new tool is a one-to-one replacement of the existing tool because the agent already knows how to perform that specific task.
Just make sure the new tool follows the same API as the replaced tool or adapt the system prompt template to ensure all examples using the replaced tool are updated.
### Use a collection of tools
You can leverage tool collections by using the ToolCollection object, with the slug of the collection you want to use.
Then pass them as a list to initialize you agent, and start using them!
> Agents and tools were spun out into the standalone [smolagents](https://huggingface.co/docs/smolagents/index) library. They were removed from `transformers` in v4.52.

# Agents, supercharged - Multi-agents, External tools, and more
[[open-in-colab]]
### What is an agent?
> [!TIP]
> If you're new to `transformers.agents`, make sure to first read the main [agents documentation](./agents).
In this page we're going to highlight several advanced uses of `transformers.agents`.
## Multi-agents
Multi-agent has been introduced in Microsoft's framework [Autogen](https://huggingface.co/papers/2308.08155).
It simply means having several agents working together to solve your task instead of only one.
It empirically yields better performance on most benchmarks. The reason for this better performance is conceptually simple: for many tasks, rather than using a do-it-all system, you would prefer to specialize units on sub-tasks. Here, having agents with separate tool sets and memories allows to achieve efficient specialization.
You can easily build hierarchical multi-agent systems with `transformers.agents`.
To do so, encapsulate the agent in a [`ManagedAgent`] object. This object needs arguments `agent`, `name`, and a `description`, which will then be embedded in the manager agent's system prompt to let it know how to call this managed agent, as we also do for tools.
Here's an example of making an agent that managed a specific web search agent using our [`DuckDuckGoSearchTool`]:
manager_agent.run("Who is the CEO of Hugging Face?")
```
> [!TIP]
> For an in-depth example of an efficient multi-agent implementation, see [how we pushed our multi-agent system to the top of the GAIA leaderboard](https://huggingface.co/blog/beating-gaia).
## Advanced tool usage
### Directly define a tool by subclassing Tool, and share it to the Hub
Let's take again the tool example from main documentation, for which we had implemented a `tool` decorator.
If you need to add variation, like custom attributes for your tool, you can build your tool following the fine-grained method: building a class that inherits from the [`Tool`] superclass.
The custom tool needs:
- An attribute `name`, which corresponds to the name of the tool itself. The name usually describes what the tool does. Since the code returns the model with the most downloads for a task, let's name it `model_download_counter`.
- An attribute `description` is used to populate the agent's system prompt.
- An `inputs` attribute, which is a dictionary with keys `"type"` and `"description"`. It contains information that helps the Python interpreter make educated choices about the input.
- An `output_type` attribute, which specifies the output type.
- A `forward` method which contains the inference code to be executed.
The types for both `inputs` and `output_type` should be amongst [Pydantic formats](https://docs.pydantic.dev/latest/concepts/json_schema/#generating-json-schema).
```python
fromtransformersimportTool
fromhuggingface_hubimportlist_models
classHFModelDownloadsTool(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":"string",
"description":"the task category (such as text-classification, depth-estimation, etc)",
Now that the custom `HfModelDownloadsTool` class is ready, you can save it to a file named `model_downloads.py` and import it for use.
```python
frommodel_downloadsimportHFModelDownloadsTool
tool=HFModelDownloadsTool()
```
You can also share your custom tool to the Hub by calling [`~Tool.push_to_hub`] on the tool. Make sure you've created a repository for it on the Hub and are using a token with read access.
You can directly import a Space from the Hub as a tool using the [`Tool.from_space`] method!
You only need to provide the id of the Space on the Hub, its name, and a description that will help you agent understand what the tool does. Under the hood, this will use [`gradio-client`](https://pypi.org/project/gradio-client/) library to call the Space.
For instance, let's import the [FLUX.1-dev](https://huggingface.co/black-forest-labs/FLUX.1-dev) Space from the Hub and use it to generate an image.
Then you can use this tool just like any other tool. For example, let's improve the prompt `a rabbit wearing a space suit` and generate an image of it.
"Improve this prompt, then generate an image of it.",prompt='A rabbit wearing a space suit'
)
```
```text
=== Agent thoughts:
improved_prompt could be "A bright blue space suit wearing rabbit, on the surface of the moon, under a bright orange sunset, with the Earth visible in the background"
Now that I have improved the prompt, I can use the image generator tool to generate an image based on this prompt.
=== Agent is executing the code below:
image = image_generator(prompt="A bright blue space suit wearing rabbit, on the surface of the moon, under a bright orange sunset, with the Earth visible in the background")
[gradio-tools](https://github.com/freddyaboulton/gradio-tools) is a powerful library that allows using Hugging
Face Spaces as tools. It supports many existing Spaces as well as custom Spaces.
Transformers supports `gradio_tools` with the [`Tool.from_gradio`] method. For example, let's use the [`StableDiffusionPromptGeneratorTool`](https://github.com/freddyaboulton/gradio-tools/blob/main/gradio_tools/tools/prompt_generator.py) from `gradio-tools` toolkit for improving prompts to generate better images.
Import and instantiate the tool, then pass it to the `Tool.from_gradio` method:
> gradio-tools require *textual* inputs and outputs even when working with different modalities like image and audio objects. Image and audio inputs and outputs are currently incompatible.
### Use LangChain tools
We love Langchain and think it has a very compelling suite of tools.
To import a tool from LangChain, use the `from_langchain()` method.
Here is how you can use it to recreate the intro's search result using a LangChain web search tool.
This tool will need `pip install google-search-results` to work properly.
agent.run("How many more blocks (also denoted as layers) are in BERT base encoder compared to the encoder from the architecture proposed in Attention is All You Need?")
```
## Display your agent run in a cool Gradio interface
You can leverage `gradio.Chatbot` to display your agent's thoughts using `stream_to_gradio`, here is an example:

# Attention Interface
This page describes how to use the `AttentionInterface` in order to register custom attention functions to use with
supported models.
## Customizing attention function
Most recent models can now switch from one attention function used in the Attention layer to the other, thanks to a simple mapping.
By default, we provide the implementation for [`sdpa`](https://pytorch.org/docs/stable/generated/torch.nn.functional.scaled_dot_product_attention.html),
[`flash_attention_2`](https://github.com/Dao-AILab/flash-attention) and [`flex_attention`](https://pytorch.org/docs/stable/nn.attention.flex_attention.html#module-torch.nn.attention.flex_attention)
as well as `eager`, which is a simple matrix multiplication without any optimization on top.
This is the setting you can usually choose when instantiating a model:
# Try running the forward with the new attention function
model(torch.ones(1,5,dtype=int))
```
You will see it prints "I just entered the attention computation" as many times as there are layers in the model (with this example, 16 times).
## Dynamically switching attention function
You could dynamically change the model's attention function as well, by overriding the `config._attn_implementation` field:
```python
# Back to use original sdpa implementation
model.config._attn_implementation="sdpa"
model(torch.ones(1,5,dtype=int))
```
and it will stop printing the statements, as it now uses the `sdpa` attention.
This allows to quickly change an attention function, without needing to reload the model!
## What about new args needed in my custom attention function?
But indeed, what if the new function requires a new arg to be properly used? It's no issue! Models supporting the
`AttentionInterface` propagate kwargs all the way to the Attention layers, and to the used attention function. That way,
you can simply pass the arg (as a kwargs, i.e. you need to qualify the name of the arg) in the model's forward, and it will be correctly used in the attention. However, custom attention functions have some limitations. In particular, it must follow the signature and return format of other attention functions, i.e.
If in doubt about what args/kwargs a given model sends to the attention function, simply check that model's modeling code on [GitHub](https://github.com/huggingface/transformers/tree/main/src/transformers/models)!
## Accessing current available implementations
Most of the time, you will simply need to `register` a new function. If, however, you need to access an existing one,
and/or perform a few checks, the preferred way is to use the global `ALL_ATTENTION_FUNCTIONS`. It behaves the same way you
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:
**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...utilsimportauto_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.
*`@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 🤗.

# Load pretrained instances with an AutoClass
With so many different Transformer architectures, it can be challenging to create one for your checkpoint. As a part of 🤗 Transformers core philosophy to make the library easy, simple and flexible to use, an `AutoClass` automatically infers and loads the correct architecture from a given checkpoint. The `from_pretrained()` method lets you quickly load a pretrained model for any architecture so you don't have to devote time and resources to train a model from scratch. Producing this type of checkpoint-agnostic code means if your code works for one checkpoint, it will work with another checkpoint - as long as it was trained for a similar task - even if the architecture is different.
<Tip>
Remember, architecture refers to the skeleton of the model and checkpoints are the weights for a given architecture. For example, [BERT](https://huggingface.co/google-bert/bert-base-uncased) is an architecture, while `google-bert/bert-base-uncased` is a checkpoint. Model is a general term that can mean either architecture or checkpoint.
</Tip>
In this tutorial, learn to:
* Load a pretrained tokenizer.
* Load a pretrained image processor
* Load a pretrained feature extractor.
* Load a pretrained processor.
* Load a pretrained model.
* Load a model as a backbone.
## AutoTokenizer
Nearly every NLP task begins with a tokenizer. A tokenizer converts your input into a format that can be processed by the model.
Load a tokenizer with [`AutoTokenizer.from_pretrained`]:
<figcaptionclass="mt-2 text-center text-sm text-gray-500">A Swin backbone with multiple stages for outputting a feature map.</figcaption>
</div>
The [`AutoBackbone`] lets you use pretrained models as backbones to get feature maps from different stages of the backbone. You should specify one of the following parameters in [`~PretrainedConfig.from_pretrained`]:
*`out_indices` is the index of the layer you'd like to get the feature map from
*`out_features` is the name of the layer you'd like to get the feature map from
These parameters can be used interchangeably, but if you use both, make sure they're aligned with each other! If you don't pass any of these parameters, the backbone returns the feature map from the last layer.
<figcaptionclass="mt-2 text-center text-sm text-gray-500">A feature map from the first stage of the backbone. The patch partition refers to the model stem.</figcaption>
</div>
For example, in the above diagram, to return the feature map from the first stage of the Swin backbone, you can set `out_indices=(1,)`:
Multimodal tasks require a processor that combines two types of preprocessing tools. For example, the [LayoutLMV2](model_doc/layoutlmv2) model requires an image processor to handle images and a tokenizer to handle text; a processor combines both of them.
Load a processor with [`AutoProcessor.from_pretrained`]:
The `AutoModelFor` classes let you load a pretrained model for a given task (see [here](model_doc/auto) for a complete list of available tasks). For example, load a model for sequence classification with [`AutoModelForSequenceClassification.from_pretrained`].
> [!WARNING]
> By default, the weights are loaded in full precision (torch.float32) regardless of the actual data type the weights are stored in such as torch.float16. Set `torch_dtype="auto"` to load the weights in the data type defined in a model's `config.json` file to automatically load the most memory-optimal data type.
For PyTorch models, the `from_pretrained()` method uses `torch.load()` which internally uses `pickle` and is known to be insecure. In general, never load a model that could have come from an untrusted source, or that could have been tampered with. This security risk is partially mitigated for public models hosted on the Hugging Face Hub, which are [scanned for malware](https://huggingface.co/docs/hub/security-malware) at each commit. See the [Hub documentation](https://huggingface.co/docs/hub/security) for best practices like [signed commit verification](https://huggingface.co/docs/hub/security-gpg#signing-commits-with-gpg) with GPG.
TensorFlow and Flax checkpoints are not affected, and can be loaded within PyTorch architectures using the `from_tf` and `from_flax` kwargs for the `from_pretrained` method to circumvent this issue.
</Tip>
Generally, we recommend using the `AutoTokenizer` class and the `AutoModelFor` class to load pretrained instances of models. This will ensure you load the correct architecture every time. In the next [tutorial](preprocessing), learn how to use your newly loaded tokenizer, image processor, feature extractor and processor to preprocess a dataset for fine-tuning.
</pt>
<tf>
Finally, the `TFAutoModelFor` classes let you load a pretrained model for a given task (see [here](model_doc/auto) for a complete list of available tasks). For example, load a model for sequence classification with [`TFAutoModelForSequenceClassification.from_pretrained`]:
Generally, we recommend using the `AutoTokenizer` class and the `TFAutoModelFor` class to load pretrained instances of models. This will ensure you load the correct architecture every time.

# Backbones
Higher-level computer visions tasks, such as object detection or image segmentation, use several models together to generate a prediction. A separate model is used for the *backbone*, neck, and head. The backbone extracts useful features from an input image into a feature map, the neck combines and processes the feature maps, and the head uses them to make a prediction.
Load a backbone with [`~PretrainedConfig.from_pretrained`] and use the `out_indices` parameter to determine which layer, given by the index, to extract a feature map from.
This guide describes the backbone class, backbones from the [timm](https://hf.co/docs/timm/index) library, and how to extract features with them.
## Backbone classes
There are two backbone classes.
- [`~transformers.utils.BackboneMixin`] allows you to load a backbone and includes functions for extracting the feature maps and indices.
- [`~transformers.utils.BackboneConfigMixin`] allows you to set the feature map and indices of a backbone configuration.
Refer to the [Backbone](./main_classes/backbones) API documentation to check which models support a backbone.
There are two ways to load a Transformers backbone, [`AutoBackbone`] and a model-specific backbone class.
<hfoptionsid="backbone-classes">
<hfoptionid="AutoBackbone">
The [AutoClass](./model_doc/auto) API automatically loads a pretrained vision model with [`~PretrainedConfig.from_pretrained`] as a backbone if it's supported.
Set the `out_indices` parameter to the layer you'd like to get the feature map from. If you know the name of the layer, you could also use `out_features`. These parameters can be used interchangeably, but if you use both, make sure they refer to the same layer.
When `out_indices` or `out_features` isn't used, the backbone returns the feature map from the last layer. The example code below uses `out_indices=(1,)` to get the feature map from the first layer.
When you know a model supports a backbone, you can load the backbone and neck directly into the models configuration. Pass the configuration to the model to initialize it for a task.
The example below loads a [ResNet](./model_doc/resnet) backbone and neck for use in a [MaskFormer](./model_doc/maskformer) instance segmentation head.
Set `backbone` to a pretrained model and `use_pretrained_backbone=True` to use pretrained weights instead of randomly initialized weights.
[timm](https://hf.co/docs/timm/index) is a collection of vision models for training and inference. Transformers supports timm models as backbones with the [`TimmBackbone`] and [`TimmBackboneConfig`] classes.
Set `use_timm_backbone=True` to load pretrained timm weights, and `use_pretrained_backbone` to use pretrained or randomly initialized weights.

# BERTology
There is a growing field of study concerned with investigating the inner working of large-scale transformers like BERT
(that some call "BERTology"). Some good examples of this field are:
- BERT Rediscovers the Classical NLP Pipeline by Ian Tenney, Dipanjan Das, Ellie Pavlick:
https://arxiv.org/abs/1905.05950
- Are Sixteen Heads Really Better than One? by Paul Michel, Omer Levy, Graham Neubig: https://arxiv.org/abs/1905.10650
- What Does BERT Look At? An Analysis of BERT's Attention by Kevin Clark, Urvashi Khandelwal, Omer Levy, Christopher D.
Manning: https://arxiv.org/abs/1906.04341
- CAT-probing: A Metric-based Approach to Interpret How Pre-trained Models for Programming Language Attend Code Structure: https://arxiv.org/abs/2210.04633
In order to help this new field develop, we have included a few additional features in the BERT/GPT/GPT-2 models to
help people access the inner representations, mainly adapted from the great work of Paul Michel
(https://arxiv.org/abs/1905.10650):
- accessing all the hidden-states of BERT/GPT/GPT-2,
- accessing all the attention weights for each head of BERT/GPT/GPT-2,
- retrieving heads output values and gradients to be able to compute head importance score and prune head as explained
in https://arxiv.org/abs/1905.10650.
To help you understand and use these features, we have added a specific example script: [bertology.py](https://github.com/huggingface/transformers/tree/main/examples/research_projects/bertology/run_bertology.py) which extracts information and prune a model pre-trained on

# Instantiate a big model
A barrier to accessing very large pretrained models is the amount of memory required. When loading a pretrained PyTorch model, you usually:
1. Create a model with random weights.
2. Load your pretrained weights.
3. Put those pretrained weights in the model.
The first two steps both require a full version of the model in memory and if the model weighs several GBs, you may not have enough memory for two copies of it. This problem is amplified in distributed training environments because each process loads a pretrained model and stores two copies in memory.
> [!TIP]
> The randomly created model is initialized with "empty" tensors, which take space in memory without filling it. The random values are whatever was in this chunk of memory at the time. To improve loading speed, the [`_fast_init`](https://github.com/huggingface/transformers/blob/c9f6e5e35156e068b227dd9b15521767f6afd4d2/src/transformers/modeling_utils.py#L2710) parameter is set to `True` by default to skip the random initialization for all weights that are correctly loaded.
This guide will show you how Transformers can help you load large pretrained models despite their memory requirements.
## Sharded checkpoints
From Transformers v4.18.0, a checkpoint larger than 10GB is automatically sharded by the [`~PreTrainedModel.save_pretrained`] method. It is split into several smaller partial checkpoints and creates an index file that maps parameter names to the files they're stored in.
The maximum shard size is controlled with the `max_shard_size` parameter, but by default it is 5GB, because it is easier to run on free-tier GPU instances without running out of memory.
For example, let's shard [BioMistral/BioMistral-7B](https://hf.co/BioMistral/BioMistral-7B).
The main advantage of sharded checkpoints for big models is that each shard is loaded after the previous one, which caps the memory usage to only the model size and the largest shard size.
You could also directly load a sharded checkpoint inside a model without the [`~PreTrainedModel.from_pretrained`] method (similar to PyTorch's `load_state_dict()` method for a full checkpoint). In this case, use the [`~modeling_utils.load_sharded_checkpoint`] method.
The index file determines which keys are in the checkpoint and where the corresponding weights are stored. This file is loaded like any other JSON file and you can get a dictionary from it.
> Make sure you have Accelerate v0.9.0 or later and PyTorch v1.9.0 or later installed.
From Transformers v4.20.0, the [`~PreTrainedModel.from_pretrained`] method is supercharged with Accelerate's [Big Model Inference](https://hf.co/docs/accelerate/usage_guides/big_modeling) feature to efficiently handle really big models! Big Model Inference creates a *model skeleton* on PyTorch's [**meta**](https://pytorch.org/docs/main/meta.html) device. The randomly initialized parameters are only created when the pretrained weights are loaded. This way, you aren't keeping two copies of the model in memory at the same time (one for the randomly initialized model and one for the pretrained weights), and the maximum memory consumed is only the full model size.
To enable Big Model Inference in Transformers, set `low_cpu_mem_usage=True` in the [`~PreTrainedModel.from_pretrained`] method.
Accelerate automatically dispatches the model weights across all available devices, starting with the fastest device (GPU) first and then offloading to the slower devices (CPU and even hard drive). This is enabled by setting `device_map="auto"` in the [`~PreTrainedModel.from_pretrained`] method. When you pass the `device_map` parameter, `low_cpu_mem_usage` is automatically set to `True` so you don't need to specify it.
You can also write your own `device_map` by mapping each layer to a device. It should map all model parameters to a device, but you don't have to detail where all the submodules of a layer go if the entire layer is on the same device.
Access `hf_device_map` attribute to see how Accelerate split the model across devices.
```py
gemma.hf_device_map
```
```python out
{'model.embed_tokens': 0,
'model.layers.0': 0,

'model.layers.29': 'cpu',
'model.layers.30': 'cpu',
'model.layers.31': 'cpu',
'model.norm': 'cpu',
'lm_head': 'cpu'}
```
## Model data type
PyTorch model weights are normally instantiated as torch.float32 and it can be an issue if you try to load a model as a different data type. For example, you'd need twice as much memory to load the weights in torch.float32 and then again to load them in your desired data type, like torch.float16.
> [!WARNING]
> Due to how PyTorch is designed, the `torch_dtype` parameter only supports floating data types.
To avoid wasting memory like this, explicitly set the `torch_dtype` parameter to the desired data type or set `torch_dtype="auto"` to load the weights with the most optimal memory pattern (the data type is automatically derived from the model weights).

# 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?
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.
To predict the 1000th token, the model requires information from the previous 999 tokens. The information is represented as matrix multiplications across the token representations.
To predict the 1001th token, you need the same information from the previous 999 tokens in addition to any information from the 1000th token. This is a lot of matrix multiplications a model has to compute over and over for each token!
A key-value (KV) cache eliminates this inefficiency by storing kv pairs derived from the attention layers of previously processed tokens. The stored kv pairs are retrieved from the cache and reused for subsequent tokens, avoiding the need to recompute.
> [!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`.
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.
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.
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.
2. When the `forward` method is called iteratively, it's crucial that the attention mask shape matches the combined length of the past and current kv pairs. The attention mask should have the shape `(batch_size, past_kv_length + new_tokens_length)`. This is typically handled internally in [`~GenerationMixin.generate`], but if you want to implement your own generation loop with [`Cache`], keep this in mind! The attention mask should hold the past and current token values.
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.
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.
"[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.
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.

# Tools and RAG
The [`~PreTrainedTokenizerBase.apply_chat_template`] method supports virtually any additional argument types - strings, lists, dicts - besides the chat message. This makes it possible to use chat templates for many use cases.
This guide will demonstrate how to use chat templates with tools and retrieval-augmented generation (RAG).
## Tools
Tools are functions a large language model (LLM) can call to perform specific tasks. It is a powerful way to extend the capabilities of conversational agents with real-time information, computational tools, or access to large databases.
Follow the rules below when creating a tool.
1. The function should have a descriptive name.
2. The function arguments must have a type hint in the function header (don't include in the `Args` block).
3. The function must have a [Google-style](https://google.github.io/styleguide/pyguide.html#38-comments-and-docstrings) docstring.
4. The function can have a return type and `Returns` block, but these are optional because most tool use models ignore them.
An example tool to get temperature and wind speed is shown below.
Load a model and tokenizer that supports tool-use like [NousResearch/Hermes-2-Pro-Llama-3-8B](https://hf.co/NousResearch/Hermes-2-Pro-Llama-3-8B), but you can also consider a larger model like [Command-R](./model_doc/cohere) and [Mixtral-8x22B](./model_doc/mixtral) if your hardware can support it.
The chat model called the `get_current_temperature` tool with the correct parameters from the docstring. It inferred France as the location based on Paris, and that it should use Celsius for the units of temperature.
Now append the `get_current_temperature` function and these arguments to the chat message as `tool_call`. The `tool_call` dictionary should be provided to the `assistant` role instead of the `system` or `user`.
> [!WARNING]
> The OpenAI API uses a JSON string as its `tool_call` format. This may cause errors or strange model behavior if used in Transformers, which expects a dict.
The temperature in Paris, France right now is approximately 12°C (53.6°F).<|im_end|>
```
</hfoption>
<hfoptionid="Mistral/Mixtral">
For [Mistral](./model_doc/mistral) and [Mixtral](./model_doc/mixtral) models, you need an additional `tool_call_id`. The `tool_call_id` is 9 randomly generated alphanumeric characters assigned to the `id` key in the `tool_call` dictionary.
[`~PreTrainedTokenizerBase.apply_chat_template`] converts functions into a [JSON schema](https://json-schema.org/learn/getting-started-step-by-step) which is passed to the chat template. A LLM never sees the code inside the function. In other words, a LLM doesn't care how the function works technically, it only cares about function **definition** and **arguments**.
The JSON schema is automatically generated behind the scenes as long as your function follows the [rules](#tools) listed earlier above. But you can use [get_json_schema](https://github.com/huggingface/transformers/blob/14561209291255e51c55260306c7d00c159381a5/src/transformers/utils/chat_template_utils.py#L205) to manually convert a schema for more visibility or debugging.
```py
fromtransformers.utilsimportget_json_schema
defmultiply(a:float,b:float):
"""
A function that multiplies two numbers
Args:
a: The first number to multiply
b: The second number to multiply
"""
returna*b
schema=get_json_schema(multiply)
print(schema)
```
```json
{
"type":"function",
"function":{
"name":"multiply",
"description":"A function that multiplies two numbers",
"parameters":{
"type":"object",
"properties":{
"a":{
"type":"number",
"description":"The first number to multiply"
},
"b":{
"type":"number",
"description":"The second number to multiply"
}
},
"required":["a","b"]
}
}
}
```
You can edit the schema or write one entirely from scratch. This gives you a lot of flexibility to define precise schemas for more complex functions.
> [!WARNING]
> Try keeping your function signatures simple and the arguments to a minimum. These are easier for a model to understand and use than complex functions for example with nested arguments.
The example below demonstrates writing a schema manually and then passing it to [`~PreTrainedTokenizerBase.apply_chat_template`].
```py
# A simple function that takes no arguments
current_time={
"type":"function",
"function":{
"name":"current_time",
"description":"Get the current local time as a string.",
"parameters":{
'type':'object',
'properties':{}
}
}
}
# A more complete function that takes two numerical arguments

## RAG
Retrieval-augmented generation (RAG) models enhance a models existing knowledge by allowing it to search documents for additional information before returning a query. For RAG models, add a `documents` parameter to [`~PreTrainedTokenizerBase.apply_chat_template`]. This `documents` parameter should be a list of documents, and each document should be a single dict with `title` and `content` keys.
> [!TIP]
> The `documents` parameter for RAG isn't widely supported and many models have chat templates that ignore `documents`. Verify if a model supports `documents` by reading its model card or executing `print(tokenizer.chat_template)` to see if the `documents` key is present. [Command-R](https://hf.co/CohereForAI/c4ai-command-r-08-2024) and [Command-R+](https://hf.co/CohereForAI/c4ai-command-r-plus-08-2024) both support `documents` in their RAG chat templates.
Create a list of documents to pass to the model.
```py
documents=[
{
"title":"The Moon: Our Age-Old Foe",
"text":"Man has always dreamed of destroying the moon. In this essay, I shall..."
},
{
"title":"The Sun: Our Age-Old Friend",
"text":"Although often underappreciated, the sun provides several notable benefits..."
}
]
```
Set `chat_template="rag"` in [`~PreTrainedTokenizerBase.apply_chat_template`] and generate a response.

# Advanced Usage and Customizing Your Chat Templates
In this page, we’ll explore more advanced techniques for working with chat templates in Transformers. Whether you’re looking to write your own templates, create custom components, or optimize your templates for efficiency, we’ll cover everything you need to take your templates to the next level. Let’s dive into the tools and strategies that will help you get the most out of your chat models.
## How do chat templates work?
The chat template for a model is stored on the `tokenizer.chat_template` attribute. Let's take a look at a `Zephyr` chat template, though note this
one is a little simplified from the actual one!
```
{%- for message in messages %}
{{- '<|' + message['role'] + '|>\n' }}
{{- message['content'] + eos_token }}
{%- endfor %}
{%- if add_generation_prompt %}
{{- '<|assistant|>\n' }}
{%- endif %}
```
If you've never seen one of these before, this is a [Jinja template](https://jinja.palletsprojects.com/en/3.1.x/templates/).
Jinja is a templating language that allows you to write simple code that generates text. In many ways, the code and
syntax resembles Python. In pure Python, this template would look something like this:
```python
formessageinmessages:
print(f'<|{message["role"]}|>')
print(message['content']+eos_token)
ifadd_generation_prompt:
print('<|assistant|>')
```
Effectively, the template does three things:
1. For each message, print the role enclosed in `<|` and `|>`, like `<|user|>` or `<|assistant|>`.
2. Next, print the content of the message, followed by the end-of-sequence token.
3. Finally, if `add_generation_prompt` is set, print the assistant token, so that the model knows to start generating
an assistant response.
This is a pretty simple template but Jinja gives you a lot of flexibility to do more complex things! Let's see a Jinja
template that can format inputs similarly to the way LLaMA formats them (note that the real LLaMA template includes
handling for default system messages and slightly different system message handling in general - don't use this one
If you like this one, here it is in one-liner form, ready to copy into your code. The one-liner also includes
handy support for [generation prompts](#what-are-generation-prompts), but note that it doesn't add BOS or EOS tokens!
If your model expects those, they won't be added automatically by `apply_chat_template` - in other words, the
text will be tokenized with `add_special_tokens=False`. This is to avoid potential conflicts between the template and
the `add_special_tokens` logic. If your model expects special tokens, make sure to add them to the template!
```python
tokenizer.chat_template="{% if not add_generation_prompt is defined %}{% set add_generation_prompt = false %}{% endif %}{% for message in messages %}{{'<|im_start|>' + message['role'] + '\n' + message['content'] + '<|im_end|>' + '\n'}}{% endfor %}{% if add_generation_prompt %}{{ '<|im_start|>assistant\n' }}{% endif %}"
```
This template wraps each message in `<|im_start|>` and `<|im_end|>` tokens, and simply writes the role as a string, which
allows for flexibility in the roles you train with. The output looks like this:
```text
<|im_start|>system
You are a helpful chatbot that will do its best not to say anything so stupid that people tweet about it.<|im_end|>
<|im_start|>user
How are you?<|im_end|>
<|im_start|>assistant
I'm doing great!<|im_end|>
```
The "user", "system" and "assistant" roles are the standard for chat, and we recommend using them when it makes sense,
particularly if you want your model to operate well with [`TextGenerationPipeline`]. However, you are not limited
to these roles - templating is extremely flexible, and any string can be a role.
## I want to add some chat templates! How should I get started?
If you have any chat models, you should set their `tokenizer.chat_template` attribute and test it using
[`~PreTrainedTokenizer.apply_chat_template`], then push the updated tokenizer to the Hub. This applies even if you're
not the model owner - if you're using a model with an empty chat template, or one that's still using the default class
template, please open a [pull request](https://huggingface.co/docs/hub/repositories-pull-requests-discussions) to the model repository so that this attribute can be set properly!
Once the attribute is set, that's it, you're done! `tokenizer.apply_chat_template` will now work correctly for that
model, which means it is also automatically supported in places like `TextGenerationPipeline`!
By ensuring that models have this attribute, we can make sure that the whole community gets to use the full power of
open-source models. Formatting mismatches have been haunting the field and silently harming performance for too long -
it's time to put an end to them!
<Tip>
The easiest way to get started with writing Jinja templates is to take a look at some existing ones. You can use
`print(tokenizer.chat_template)` for any chat model to see what template it's using. In general, models that support tool use have
much more complex templates than other models - so when you're just getting started, they're probably a bad example
to learn from! You can also take a look at the
[Jinja documentation](https://jinja.palletsprojects.com/en/3.1.x/templates/#synopsis) for details
of general Jinja formatting and syntax.
</Tip>
Jinja templates in `transformers` are identical to Jinja templates elsewhere. The main thing to know is that
the conversation history will be accessible inside your template as a variable called `messages`.
You will be able to access `messages` in your template just like you can in Python, which means you can loop over
it with `{% for message in messages %}` or access individual messages with `{{ messages[0] }}`, for example.
You can also use the following tips to write clean, efficient Jinja templates:
### Trimming whitespace
By default, Jinja will print any whitespace that comes before or after a block. This can be a problem for chat
templates, which generally want to be very precise with whitespace! To avoid this, we strongly recommend writing
your templates like this:
```
{%- for message in messages %}
{{- message['role'] + message['content'] }}
{%- endfor %}
```
rather than like this:
```
{% for message in messages %}
{{ message['role'] + message['content'] }}
{% endfor %}
```
Adding `-` will strip any whitespace that comes before the block. The second example looks innocent, but the newline
and indentation may end up being included in the output, which is probably not what you want!
### Special variables
Inside your template, you will have access several special variables. The most important of these is `messages`,
which contains the chat history as a list of message dicts. However, there are several others. Not every
variable will be used in every template. The most common other variables are:
-`tools` contains a list of tools in JSON schema format. Will be `None` or undefined if no tools are passed.
-`documents` contains a list of documents in the format `{"title": "Title", "contents": "Contents"}`, used for retrieval-augmented generation. Will be `None` or undefined if no documents are passed.
-`add_generation_prompt` is a bool that is `True` if the user has requested a generation prompt, and `False` otherwise. If this is set, your template should add the header for an assistant message to the end of the conversation. If your model doesn't have a specific header for assistant messages, you can ignore this flag.
- **Special tokens** like `bos_token` and `eos_token`. These are extracted from `tokenizer.special_tokens_map`. The exact tokens available inside each template will differ depending on the parent tokenizer.
<Tip>
You can actually pass any `kwarg` to `apply_chat_template`, and it will be accessible inside the template as a variable. In general,
we recommend trying to stick to the core variables above, as it will make your model harder to use if users have
to write custom code to pass model-specific `kwargs`. However, we're aware that this field moves quickly, so if you
have a new use-case that doesn't fit in the core API, feel free to use a new `kwarg` for it! If a new `kwarg`
becomes common we may promote it into the core API and create a standard, documented format for it.
</Tip>
### Callable functions
There is also a short list of callable functions available to you inside your templates. These are:
-`raise_exception(msg)`: Raises a `TemplateException`. This is useful for debugging, and for telling users when they're
doing something that your template doesn't support.
-`strftime_now(format_str)`: Equivalent to `datetime.now().strftime(format_str)` in Python. This is used for getting
the current date/time in a specific format, which is sometimes included in system messages.
### Compatibility with non-Python Jinja
There are multiple implementations of Jinja in various languages. They generally have the same syntax,
but a key difference is that when you're writing a template in Python you can use Python methods, such as
`.lower()` on strings or `.items()` on dicts. This will break if someone tries to use your template on a non-Python
implementation of Jinja. Non-Python implementations are particularly common in deployment environments, where JS
and Rust are very popular.
Don't panic, though! There are a few easy changes you can make to your templates to ensure they're compatible across
all implementations of Jinja:
- Replace Python methods with Jinja filters. These usually have the same name, for example `string.lower()` becomes
`string|lower`, and `dict.items()` becomes `dict|items`. One notable change is that `string.strip()` becomes `string|trim`.
See the [list of built-in filters](https://jinja.palletsprojects.com/en/3.1.x/templates/#builtin-filters)
in the Jinja documentation for more.
- Replace `True`, `False` and `None`, which are Python-specific, with `true`, `false` and `none`.
- Directly rendering a dict or list may give different results in other implementations (for example, string entries
might change from single-quoted to double-quoted). Adding the `tojson` filter can help to ensure consistency here.
### Writing generation prompts
We mentioned above that `add_generation_prompt` is a special variable that will be accessible inside your template,
and is controlled by the user setting the `add_generation_prompt` flag. If your model expects a header for
assistant messages, then your template must support adding the header when `add_generation_prompt` is set.
Here is an example of a template that formats messages ChatML-style, with generation prompt support:

# Getting Started with Chat Templates for Text LLMs
An increasingly common use case for LLMs is **chat**. In a chat context, rather than continuing a single string
of text (as is the case with a standard language model), the model instead continues a conversation that consists
of one or more **messages**, each of which includes a **role**, like "user" or "assistant", as well as message text.
Much like tokenization, different models expect very different input formats for chat. This is the reason we added
**chat templates** as a feature. Chat templates are part of the tokenizer for text-only LLMs or processor for multimodal LLMs. They specify how to convert conversations, represented as lists of messages, into a single tokenizable string in the format that the model expects.
We'll explore the basic usage of chat templates with text-only LLMs in this page. For detailed guidance on multimodal models, we have a dedicated [documentation oage for multimodal models](./chat_template_multimodal), which covers how to work with image, video and audio inputs in your templates.
Let's make this concrete with a quick example using the `mistralai/Mistral-7B-Instruct-v0.1` model:
You are a friendly chatbot who always responds in the style of a pirate</s>
<|user|>
How many helicopters can a human eat in one sitting?</s>
<|assistant|>
Matey, I'm afraid I must inform ye that humans cannot eat helicopters. Helicopters are not food, they are flying machines. Food is meant to be eaten, like a hearty plate o' grog, a savory bowl o' stew, or a delicious loaf o' bread. But helicopters, they be for transportin' and movin' around, not for eatin'. So, I'd say none, me hearties. None at all.
```
Arr, 'twas easy after all!
## Is there an automated pipeline for chat?
Yes, there is! Our text generation pipelines support chat inputs, which makes it easy to use chat models. In the past,
we used to use a dedicated "ConversationalPipeline" class, but this has now been deprecated and its functionality
has been merged into the [`TextGenerationPipeline`]. Let's try the `Zephyr` example again, but this time using
"content":"You are a friendly chatbot who always responds in the style of a pirate",
},
{"role":"user","content":"How many helicopters can a human eat in one sitting?"},
]
print(pipe(messages,max_new_tokens=128)[0]['generated_text'][-1])# Print the assistant's response
```
```text
{'role': 'assistant', 'content': "Matey, I'm afraid I must inform ye that humans cannot eat helicopters. Helicopters are not food, they are flying machines. Food is meant to be eaten, like a hearty plate o' grog, a savory bowl o' stew, or a delicious loaf o' bread. But helicopters, they be for transportin' and movin' around, not for eatin'. So, I'd say none, me hearties. None at all."}
```
The pipeline will take care of all the details of tokenization and calling `apply_chat_template` for you -
once the model has a chat template, all you need to do is initialize the pipeline and pass it the list of messages!
## What are "generation prompts"?
You may have noticed that the `apply_chat_template` method has an `add_generation_prompt` argument. This argument tells
the template to add tokens that indicate the start of a bot response. For example, consider the following chat:
```python
messages=[
{"role":"user","content":"Hi there!"},
{"role":"assistant","content":"Nice to meet you!"},
{"role":"user","content":"Can I ask a question?"}
]
```
Here's what this will look like without a generation prompt, for a model that uses standard "ChatML" formatting:

# Multimodal Chat Templates for Vision and Audio LLMs
In this section, we'll explore how to use chat templates with multimodal models, enabling your templates to handle a variety of inputs such as text, images, and audio. Multimodal models provide richer, more interactive experiences, and understanding how to effectively combine these inputs within your templates is key. We’ll walk through how to work with different modalities, configure your templates for optimal performance, and tackle common challenges along the way.
Just like with text-only LLMs, multimodal models expect a chat with **messages**, each of which includes a **role** and **content**. However, for multimodal models, chat templates are a part of the [Processor](./main_cllasses/processors) class. Let's see how we can format our prompts when there are images or videos in the input along with text.
## Image inputs
For models such as [LLaVA](https://huggingface.co/llava-hf) the prompts can be formatted as below. Notice that the only difference from text-only models is that we need to also pass a placeholder for input images. To accommodate for extra modalities, each **content** is a list containing either a text or an image **type**.
Let's make this concrete with a quick example using the `llava-hf/llava-onevision-qwen2-0.5b-ov-hf` model:
This yields a string in LLaVA's expected input format with many `<image>` tokens prepended before the text.
```text
'<|im_start|>system
<|im_start|>system
You are a friendly chatbot who always responds in the style of a pirate<|im_end|><|im_start|>user <image>
What are these?<|im_end|>
```
### Image paths or URLs
To incorporate images into your chat templates, you can pass them as file paths or URLs. This method automatically loads the image, processes it, and prepares the necessary pixel values to create ready-to-use inputs for the model. This approach simplifies the integration of images, enabling seamless multimodal functionality.
Let's see how it works with an example using the same model as above. This time we'll indicate an image URL with `"url"` key in the message's **content** and ask the chat template to `tokenize` and `return_dict`. Currently, "base64", "url", and "path" are supported image sources.
Some vision models support videos as inputs as well as images. The message format is very similar to the image-only models with tiny differences to handle loading videos from a URL. We can continue using the same model as before since it supports videos.
### Sampling with fixed number of frames
Here's an example of how to set up a conversation with video inputs. Notice the extra `kwargs` passed to `processor.apply_chat_template()`. The key parameter here is `num_frames`, which controls how many frames to sample uniformly from the video. Each model checkpoint has a maximum frame count it was trained with, and exceeding this limit can significantly impact generation quality. So, it’s important to choose a frame count that fits both the model's capacity and your computational resources. If you don't specify `num_frames`, the entire video will be loaded without any frame sampling.
You also have the option to choose a specific framework to load the video, depending on your preferences or needs. Currently, we support `decord`, `pyav` (the default), `opencv`, and `torchvision`. For this example, we’ll use `decord`, as it's a bit faster than `pyav`.
<Tip>
Note that if you are trying to load a video from URL, you can decode the video only with `pyav` or `decord` as backend.
{"type":"text","text":"What do you see in this video?"},
],
},
]
processed_chat=processor.apply_chat_template(
messages,
add_generation_prompt=True,
tokenize=True,
return_dict=True,
return_tensors="pt",
num_frames=32,
video_load_backend="decord",
)
print(processed_chat.keys())
```
### Sampling with FPS
When working with long videos, you might want to sample more frames for better representation. Instead of a fixed number of frames, you can specify `video_fps`, which determines how many frames per second to extract. For example, if a video is **10 seconds long** and you set `video_fps=2`, the model will sample **20 frames** (2 per second, uniformly spaced).
Using the above model, we need to apply chat template as follows to sample 2 frames per second.
```python
processed_chat=processor.apply_chat_template(
messages,
add_generation_prompt=True,
tokenize=True,
return_dict=True,
video_fps=32,
video_load_backend="decord",
)
print(processed_chat.keys())
```
### Custom Frame Sampling with a Function
Not all models sample frames **uniformly** — some require more complex logic to determine which frames to use. If your model follows a different sampling strategy, you can **customize** frame selection by providing a function:
🔹 Use the `sample_indices_fn` argument to pass a **callable function** for sampling.
🔹 If provided, this function **overrides** standard `num_frames` and `fps` methods.
🔹 It receives all the arguments passed to `load_video` and must return **valid frame indices** to sample.
You should use `sample_indices_fn` when:
- If you need a custom sampling strategy (e.g., **adaptive frame selection** instead of uniform sampling).
- If your model prioritizes **key moments** in a video rather than evenly spaced frames.
Here’s an example of how to implement it:
```python
defsample_indices_fn(metadata,**kwargs):
# samples only the first and the second frame
return[0,1]
processed_chat=processor.apply_chat_template(
messages,
add_generation_prompt=True,
tokenize=True,
return_dict=True,
sample_indices_fn=sample_indices_fn,
video_load_backend="decord",
)
print(processed_chat.keys())
```
By using `sample_indices_fn`, you gain **full control** over frame selection, making your model **more adaptable** to different video scenarios. 🚀
### List of image frames as video
Sometimes, instead of having a full video file, you might only have a set of sampled frames stored as images.
You can pass a list of image file paths, and the processor will automatically concatenate them into a video. Just make sure that all images have the same size, as they are assumed to be from the same video.
"content":[{"type":"text","text":"You are a friendly chatbot who always responds in the style of a pirate"}],
},
{
"role":"user",
"content":[
{"type":"video","path":frames_paths},
{"type":"text","text":"What do you see in this video?"},
],
},
]
processed_chat=processor.apply_chat_template(
messages,
add_generation_prompt=True,
tokenize=True,
return_dict=True,
)
print(processed_chat.keys())
```
## Multimodal conversational pipeline
[`ImageTextToTextPipeline`] currently accepts images as inputs but we are planning to add support for video inputs in the future. The pipeline supports chat inputs in the same format as we have seen above. Apart from that, the pipeline will accept chats in OpenAI format. This format is supported exclusively within the pipeline to make inference easier and more accessible.
## Best Practices for Multimodal Template Configuration
To add a custom chat template for your multimodal LLM, simply create your template using [Jinja](https://jinja.palletsprojects.com/en/3.1.x/templates/) and set it with `processor.chat_template`. If you're new to writing chat templates or need some tips, check out our [tutorial here](./chat_template_advanced) for helpful guidance.
In some cases, you may want your template to handle a **list of content** from multiple modalities, while still supporting a plain string for text-only inference. Here's an example of how you can achieve that, using the [Llama-Vision](https://huggingface.co/collections/meta-llama/metas-llama-32-multimodal-models-675bfd70e574a62dd0e4059b) chat template.
```
{% for message in messages %}
{% if loop.index0 == 0 %}{{ bos_token }}{% endif %}
{% if add_generation_prompt %}{{ '<|start_header_id|>assistant<|end_header_id|>\n\n' }}{% endif %}
```
