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

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

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

> [!WARNING]
> Caching should only be used for **inference**. It may cause unexpected errors if it's enabled during training.
To better understand how and why caching works, let's take a closer look at the structure of the attention matrices.
## Attention matrices
The **scaled dot-product attention** is calculated as shown below for a batch of size `b`, number of attention heads `h`, sequence length so far `T`, and dimension per attention head `d_head`.
$$
\text{Attention}(Q, K, V) = \text{softmax}\left( \frac{Q K^\top}{\sqrt{d_{\text{head}}}} \times \text{mask} \right) V
$$
The query (`Q`), key (`K`), and value (`V`) matrices are projections from the input embeddings of shape `(b, h, T, d_head)`.
For causal attention, the mask prevents the model from attending to future tokens. Once a token is processed, its representation never changes with respect to future tokens, which means \\( K_{\text{past}} \\) and \\( V_{\text{past}} \\) can be cached and reused to compute the last token's representation.
$$
\text{Attention}(q_t, [\underbrace{k_1, k_2, \dots, k_{t-1}}_{\text{cached}}, k_{t}], [\underbrace{v_1, v_2, \dots, v_{t-1}}_{\text{cached}}, v_{t}])
$$
At inference time, you only need the last token's query to compute the representation \\( x_t \\) that predicts the next token \\( t+1 \\). At each step, the new key and value vectors are **stored** in the cache and **appended** to the past keys and values.
$$
K_{\text{cache}} \leftarrow \text{concat}(K_{\text{past}}, k_t), \quad V_{\text{cache}} \leftarrow \text{concat}(V_{\text{past}}, v_t)
$$
Attention is calculated independently in each layer of the model, and caching is done on a per-layer basis.
Refer to the table below to compare how caching improves efficiency.
| without caching | with caching |
|---|---|
| for each step, recompute all previous `K` and `V` | for each step, only compute current `K` and `V`
| attention cost per step is **quadratic** with sequence length | attention cost per step is **linear** with sequence length (memory grows linearly, but compute/token remains low) |
## Cache class
A basic KV cache interface takes a key and value tensor for the current token and returns the updated `K` and `V` tensors. This is internally managed by a model's `forward` method.
```py
new_K, new_V = cache.update(k_t, v_t, layer_idx)
attn_output = attn_layer_idx_fn(q_t, new_K, new_V)
```
When you use Transformers' [`Cache`] class, the self-attention module performs several critical steps to integrate past and present information.
1. The attention module concatenates current kv pairs with past kv pairs stored in the cache. This creates attentions weights with the shape `(new_tokens_length, past_kv_length + new_tokens_length)`. The current and past kv pairs are essentially combined to compute the attention scores, ensuring a model is aware of previous context and the current input.
@ -80,27 +39,6 @@ When you use Transformers' [`Cache`] class, the self-attention module performs s
3. It is also important to be aware of the `cache_position`. This is important if you want to reuse a prefilled [`Cache`] with the `forward` method because you have to pass a valid `cache_position` value. This indicates the input positions in a sequence. `cache_position` is unaffected by padding, and it always adds one more position for each token. For example, if a kv cache contains 10 tokens - regardless of pad tokens - the cache position for the next token should be `torch.tensor([10])`.
## Cache storage implementation
The actual storage of key-value pairs varies between cache implementations. As an example, consider the [`DynamicCache`].
In [`DynamicCache`], the key-value pairs are stored as two lists of tensors. Each tensor in the lists have the shape `[batch_size, num_heads, seq_len, head_dim]`.
- `key_cache`: A list of tensors, one for each layer.
- `value_cache`: A list of tensors, one for each layer.
When new tokens are processed:
1. For each layer, the new key and value states are concatenated with the existing cache.
```py
self.key_cache[layer_idx] = torch.cat([self.key_cache[layer_idx], key_states], dim=-2)
self.value_cache[layer_idx] = torch.cat([self.value_cache[layer_idx], value_states], dim=-2)
```
2. The cache grows dynamically as more tokens are processed. The sequence length dimension (`seq_len`) increases with each new token.
3. The cache maintains a count of seen tokens through `self._seen_tokens`. This is updated when the first layer processes a new token.
The example below demonstrates how to create a generation loop with [`DynamicCache`]. As discussed, the attention mask is a concatenation of past and current token values and `1` is added to the cache position for the next token.
```py
@ -134,14 +72,10 @@ for _ in range(max_new_tokens):
print(tokenizer.batch_decode(generated_ids, skip_special_tokens=True)[0])
"[INST] Hello, what's your name. [/INST] Hello! My name is LLaMA,"
```
## Legacy cache format
Before the [`Cache`] class, the cache used to be stored as a tuple of tuples of tensors. This format is dynamic because it grows as text is generated, similar to [`DynamicCache`].
The legacy format is essentially the same data structure but organized differently.
- It's a tuple of tuples, where each inner tuple contains the key and value tensors for a layer.
- The tensors have the same shape `[batch_size, num_heads, seq_len, head_dim]`.
- The format is less flexible and doesn't support features like quantization or offloading.
Before the [`Cache`] class, the cache used to be stored as a tuple of tuples of tensors. This format has is dynamic because it grows as text is generated, similar to [`DynamicCache`].
If your project depends on this legacy format, you can convert between [`DynamicCache`] and a tuple of tuples as shown below with the [`~DynamicCache.from_legacy_cache`] and [`DynamicCache.to_legacy_cache`] functions. This is helpful if you have custom logic for manipulating a cache in a specific format.

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

#### Saving tensors to disk
Some model adders may benefit from logging full tensor values to disk to support, for example, numerical analysis
across implementations.
Set `use_repr=False` to write tensors to disk using [SafeTensors](https://huggingface.co/docs/safetensors/en/index).
```python
with model_addition_debugger_context(
model,
debug_path="optional_path_to_your_directory",
do_prune_layers=False,
use_repr=False, # Defaults to True
):
output = model.forward(**inputs)
```
When using `use_repr=False`, tensors are written to the same disk location as the `_SUMMARY.json` and
`_FULL_TENSORS.json` files. The `value` property of entries in the `_FULL_TENSORS.json` file will contain a relative
path reference to the associated `.safetensors` file. Each tensor is written to its own file as the `data` property of
the state dictionary. File names are constructed using the `module_path` as a prefix with a few possible postfixes that
are built recursively.
* Module inputs are denoted with the `_inputs` and outputs by `_outputs`.
* `list` and `tuple` instances, such as `args` or function return values, will be postfixed with `_{index}`.
* `dict` instances will be postfixed with `_{key}`.
### Comparing between implementations
Once the forward passes of two models have been traced by the debugger, one can compare the `json` output files. See
below: we can see slight differences between these two implementations' key projection layer. Inputs are mostly
identical, but not quite. Looking through the file differences makes it easier to pinpoint which layer is wrong.

traced once instead of reran N times with breakpoints.

### Sink cache
[`SinkCache`] is capable of generating very long sequences ("infinite length" according to the paper) by only retaining a few initial tokens from the sequence. These are called the *sink tokens* because they account for a significant portion of the attention scores during generation. Subsequent tokens are discarded on a sliding windowed basis, and only the latest `window_size` tokens are kept. This means most of the previous knowledge is discarded.
The sink tokens allow a model to maintain stable performance even when it's dealing with very long text sequences.
Enable [`SinkCache`] by initializing it first with the [window_length](https://hf.co/docs/transformers/main/en/internal/generation_utils#transformers.SinkCache.window_length) and [num_sink_tokens](https://hf.co/docs/transformers/main/en/internal/generation_utils#transformers.SinkCache.num_sink_tokens) parameters before passing it to [past_key_values](https://hf.co/docs/transformers/internal/generation_utils#transformers.generation.GenerateDecoderOnlyOutput.past_key_values) in [`~GenerationMixin.generate`].

The default [`DynamicCache`] prevents you from taking advantage of just-in-time (JIT) optimizations because the cache size isn't fixed.

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

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

## Notes
- ALIGN projects the text and visual features into latent space and the dot product between the projected image and text features is used as the similarity score. The example below demonstrates how to calculate the image-text similarity score with [`AlignProcessor`] and [`AlignModel`].
```py
# Example of using ALIGN for image-text similarity
from transformers import AlignProcessor, AlignModel
import torch
from PIL import Image
import requests
from io import BytesIO
# Load processor and model
processor = AlignProcessor.from_pretrained("kakaobrain/align-base")
model = AlignModel.from_pretrained("kakaobrain/align-base")
# Download image from URL
url = "https://huggingface.co/roschmid/dog-races/resolve/main/images/Golden_Retriever.jpg"
response = requests.get(url)
image = Image.open(BytesIO(response.content)) # Convert the downloaded bytes to a PIL Image
texts = ["a photo of a cat", "a photo of a dog"]
# Process image and text inputs
inputs = processor(images=image, text=texts, return_tensors="pt")
# Get the embeddings
with torch.no_grad():
outputs = model(**inputs)
image_embeds = outputs.image_embeds
text_embeds = outputs.text_embeds
# Normalize embeddings for cosine similarity
image_embeds = image_embeds / image_embeds.norm(dim=1, keepdim=True)
text_embeds = text_embeds / text_embeds.norm(dim=1, keepdim=True)
# Calculate similarity scores
similarity_scores = torch.matmul(text_embeds, image_embeds.T)
# Print raw scores
print("Similarity scores:", similarity_scores)
# Convert to probabilities
probs = torch.nn.functional.softmax(similarity_scores, dim=0)
print("Probabilities:", probs)
# Get the most similar text
most_similar_idx = similarity_scores.argmax().item()
print(f"Most similar text: '{texts[most_similar_idx]}'")
```

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

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

Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
The example below uses [torchao](../quantization/torchao) to only quantize the weights to int4 and the [rhymes-ai/Aria-sequential_mlp](https://huggingface.co/rhymes-ai/Aria-sequential_mlp) checkpoint. This checkpoint replaces grouped GEMM with `torch.nn.Linear` layers for easier quantization.
```py
# pip install torchao
import torch
from transformers import TorchAoConfig, AutoModelForCausalLM, AutoProcessor
quantization_config = TorchAoConfig("int4_weight_only", group_size=128)
model = AutoModelForCausalLM.from_pretrained(

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

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

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

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

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

- For an in-detail explanation on how BigBird's attention works, see [this blog post](https://huggingface.co/blog/big-bird).
- BigBird comes with 2 implementations: **original_full** & **block_sparse**. For the sequence length < 1024, using
**original_full** is advised as there is no benefit in using **block_sparse** attention.
- The code currently uses window size of 3 blocks and 2 global blocks.
- Sequence length must be divisible by block size.
- Current implementation supports only **ITC**.
- Current implementation doesn't support **num_random_blocks = 0**
- BigBird is a model with absolute position embeddings so it's usually advised to pad the inputs on the right rather than
the left.
```py
import torch
from transformers import AutoModelForMaskedLM, AutoTokenizer
tokenizer = AutoTokenizer.from_pretrained(
"google/bigbird-roberta-base",
)
model = AutoModelForMaskedLM.from_pretrained(
"google/bigbird-roberta-base",
torch_dtype=torch.float16,

)
inputs = tokenizer("Plants create [MASK] through a process known as photosynthesis.", return_tensors="pt").to("cuda")
with torch.no_grad():
outputs = model(**inputs)
predictions = outputs.logits
masked_index = torch.where(inputs['input_ids'] == tokenizer.mask_token_id)[1]
predicted_token_id = predictions[0, masked_index].argmax(dim=-1)
predicted_token = tokenizer.decode(predicted_token_id)
print(f"The predicted token is: {predicted_token}")

```
</hfoption>
</hfoptions>
## Notes
- Inputs should be padded on the right because BigBird uses absolute position embeddings.
- BigBird supports `original_full` and `block_sparse` attention. If the input sequence length is less than 1024, it is recommended to use `original_full` since sparse patterns don't offer much benefit for smaller inputs.
- The current implementation uses window size of 3 blocks and 2 global blocks, only supports the ITC-implementation, and doesn't support `num_random_blocks=0`.
- The sequence length must be divisible by the block size.

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

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

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

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

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

- current implementation uses the "naive" attention compution (so not really MLA)
- current implementation loops through the experts. This should be replaced. Pointers to use `get_packed_weights` from `integrations/tensor_parallel`.
- current implementation uses the eleuther formula for ROPE, using the original one would be more efficient! (should still follow our API)

## Overview
The GPTNeo model was released in the [EleutherAI/gpt-neo](https://github.com/EleutherAI/gpt-neo) repository by Sid
Black, Stella Biderman, Leo Gao, Phil Wang and Connor Leahy. It is a GPT2 like causal language model trained on the
[Pile](https://pile.eleuther.ai/) dataset.
The architecture is similar to GPT2 except that GPT Neo uses local attention in every other layer with a window size of
256 tokens.
This model was contributed by [valhalla](https://huggingface.co/valhalla).
## Usage example
The `generate()` method can be used to generate text using GPT Neo model.
```python
>>> from transformers import GPTNeoForCausalLM, GPT2Tokenizer
>>> model = GPTNeoForCausalLM.from_pretrained("EleutherAI/gpt-neo-1.3B")
>>> tokenizer = GPT2Tokenizer.from_pretrained("EleutherAI/gpt-neo-1.3B")
>>> prompt = (
... "In a shocking finding, scientists discovered a herd of unicorns living in a remote, "
... "previously unexplored valley, in the Andes Mountains. Even more surprising to the "
... "researchers was the fact that the unicorns spoke perfect English."
... )
>>> input_ids = tokenizer(prompt, return_tensors="pt").input_ids
>>> gen_tokens = model.generate(
... input_ids,
... do_sample=True,
... temperature=0.9,
... max_length=100,
... )
>>> gen_text = tokenizer.batch_decode(gen_tokens)[0]
```
## Combining GPT-Neo and Flash Attention 2
First, make sure to install the latest version of Flash Attention 2 to include the sliding window attention feature, and make sure your hardware is compatible with Flash-Attention 2. More details are available [here](https://huggingface.co/docs/transformers/perf_infer_gpu_one#flashattention-2) concerning the installation.
Make sure as well to load your model in half-precision (e.g. `torch.float16`).
To load and run a model using Flash Attention 2, refer to the snippet below:
```python
>>> import torch
>>> from transformers import AutoModelForCausalLM, AutoTokenizer
>>> device = "cuda" # the device to load the model onto
>>> model = AutoModelForCausalLM.from_pretrained("EleutherAI/gpt-neo-2.7B", torch_dtype=torch.float16, attn_implementation="flash_attention_2")
>>> tokenizer = AutoTokenizer.from_pretrained("EleutherAI/gpt-neo-2.7B")
>>> prompt = "def hello_world():"
>>> model_inputs = tokenizer([prompt], return_tensors="pt").to(device)
>>> model.to(device)
>>> generated_ids = model.generate(**model_inputs, max_new_tokens=100, do_sample=True)
>>> tokenizer.batch_decode(generated_ids)[0]
"def hello_world():\n >>> run_script("hello.py")\n >>> exit(0)\n<|endoftext|>"
```
### Expected speedups
Below is an expected speedup diagram that compares pure inference time between the native implementation in transformers using `EleutherAI/gpt-neo-2.7B` checkpoint and the Flash Attention 2 version of the model.
Note that for GPT-Neo it is not possible to train / run on very long context as the max [position embeddings](https://huggingface.co/EleutherAI/gpt-neo-2.7B/blob/main/config.json#L58 ) is limited to 2048 - but this is applicable to all gpt-neo models and not specific to FA-2

Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
The example below uses [bitsandbytes](../quantization/bitsandbytes) to only quantize the weights to 4-bits.
```py
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig
quantization_config = BitsAndBytesConfig(
load_in_4bit=True,
bnb_4bit_quant_type="nf4",
bnb_4bit_compute_dtype="float16",
bnb_4bit_use_double_quant=True
)
model = AutoModelForCausalLM.from_pretrained(
"EleutherAI/gpt-neo-2.7B",
quantization_config=quantization_config,
device_map="auto"
)
tokenizer = AutoTokenizer.from_pretrained("EleutherAI/gpt-neo-2.7B")
inputs = tokenizer("Hello, I'm a language model", return_tensors="pt").to("cuda")
outputs = model.generate(**inputs, max_new_tokens=100)
print(tokenizer.decode(outputs[0], skip_special_tokens=True))
```

# Granite
## Overview
[Granite](https://huggingface.co/papers/2408.13359) is a 3B parameter language model trained with the Power scheduler. Discovering a good learning rate for pretraining large language models is difficult because it depends on so many variables (batch size, number of training tokens, etc.) and it is expensive to perform a hyperparameter search. The Power scheduler is based on a power-law relationship between the variables and their transferability to larger models. Combining the Power scheduler with Maximum Update Parameterization (MUP) allows a model to be pretrained with one set of hyperparameters regardless of all the variables.
The Granite model was proposed in [Power Scheduler: A Batch Size and Token Number Agnostic Learning Rate Scheduler](https://arxiv.org/abs/2408.13359) by Yikang Shen, Matthew Stallone, Mayank Mishra, Gaoyuan Zhang, Shawn Tan, Aditya Prasad, Adriana Meza Soria, David D. Cox and Rameswar Panda.
You can find all the original Granite checkpoints under the [IBM-Granite](https://huggingface.co/ibm-granite) organization.
PowerLM-3B is a 3B state-of-the-art small language model trained with the Power learning rate scheduler. It is trained on a wide range of open-source and synthetic datasets with permissive licenses. PowerLM-3B has shown promising results compared to other models in the size categories across various benchmarks, including natural language multi-choices, code generation, and math reasoning.

The abstract from the paper is the following:
The example below demonstrates how to generate text with [`Pipeline`], [`AutoModel`, and from the command line.
*Finding the optimal learning rate for language model pretraining is a challenging task.
This is not only because there is a complicated correlation between learning rate, batch size, number of training tokens, model size, and other hyperparameters but also because it is prohibitively expensive to perform a hyperparameter search for large language models with Billions or Trillions of parameters. Recent studies propose using small proxy models and small corpus to perform hyperparameter searches and transposing the optimal parameters to large models and large corpus. While the zero-shot transferability is theoretically and empirically proven for model size related hyperparameters, like depth and width, the zero-shot transfer from small corpus to large corpus is underexplored.
In this paper, we study the correlation between optimal learning rate, batch size, and number of training tokens for the recently proposed WSD scheduler. After thousands of small experiments, we found a power-law relationship between variables and demonstrated its transferability across model sizes. Based on the observation, we propose a new learning rate scheduler, Power scheduler, that is agnostic about the number of training tokens and batch size. The experiment shows that combining the Power scheduler with Maximum Update Parameterization (\mup) can consistently achieve impressive performance with one set of hyperparameters regardless of the number of training tokens, batch size, model size, and even model architecture. Our 3B dense and MoE models trained with the Power scheduler achieve comparable performance as state-of-the-art small language models.

# Mamba
[Mamba](https://huggingface.co/papers/2312.00752) is a selective structured state space model (SSMs) designed to work around Transformers computational inefficiency when dealing with long sequences. It is a completely attention-free architecture, and comprised of a combination of H3 and gated MLP blocks (Mamba block). Mamba's "content-based reasoning" allows it to focus on specific parts of an input depending on the current token. Mamba also uses a new hardware-aware parallel algorithm to compensate for the lack of convolutional operations. As a result, Mamba has fast inference and can scale to very long sequences.

You can find all the original Mamba checkpoints under the [State Space Models](https://huggingface.co/state-spaces) organization.
## Overview
The Mamba model was proposed in [Mamba: Linear-Time Sequence Modeling with Selective State Spaces](https://arxiv.org/abs/2312.00752) by Albert Gu and Tri Dao.

This model is a new paradigm architecture based on `state-space-models`. You can read more about the intuition behind these [here](https://srush.github.io/annotated-s4/).
The example below demonstrates how to generate text with [`Pipeline`], [`AutoModel`], and from the command line.
The abstract from the paper is the following:
<hfoptions id="usage">
<hfoption id="Pipeline">
*Foundation models, now powering most of the exciting applications in deep learning, are almost universally based on the Transformer architecture and its core attention module. Many subquadratic-time architectures such as linear attention, gated convolution and recurrent models, and structured state space models (SSMs) have been developed to address Transformers' computational inefficiency on long sequences, but they have not performed as well as attention on important modalities such as language. We identify that a key weakness of such models is their inability to perform content-based reasoning, and make several improvements. First, simply letting the SSM parameters be functions of the input addresses their weakness with discrete modalities, allowing the model to selectively propagate or forget information along the sequence length dimension depending on the current token. Second, even though this change prevents the use of efficient convolutions, we design a hardware-aware parallel algorithm in recurrent mode. We integrate these selective SSMs into a simplified end-to-end neural network architecture without attention or even MLP blocks (Mamba). Mamba enjoys fast inference (5× higher throughput than Transformers) and linear scaling in sequence length, and its performance improves on real data up to million-length sequences. As a general sequence model backbone, Mamba achieves state-of-the-art performance across several modalities such as language, audio, and genomics. On language modeling, our Mamba-3B model outperforms Transformers of the same size and matches Transformers twice its size, both in pretraining and downstream evaluation.*
```py
Tips:
- Mamba is a new `state space model` architecture that rivals the classic Transformers. It is based on the line of progress on structured state space models, with an efficient hardware-aware design and implementation in the spirit of [FlashAttention](https://github.com/Dao-AILab/flash-attention).
- Mamba stacks `mixer` layers, which are the equivalent of `Attention` layers. The core logic of `mamba` is held in the `MambaMixer` class.
- Two implementations cohabit: one is optimized and uses fast cuda kernels, while the other one is naive but can run on any device!
- The current implementation leverages the original cuda kernels: the equivalent of flash attention for Mamba are hosted in the [`mamba-ssm`](https://github.com/state-spaces/mamba) and the [`causal_conv1d`](https://github.com/Dao-AILab/causal-conv1d) repositories. Make sure to install them if your hardware supports them!
- Contributions to make the naive path faster are welcome 🤗

### Peft finetuning
The slow version is not very stable for training, and the fast one needs `float32`!
```bash

Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
The example below uses [torchao](../quantization/torchao) to only quantize the weights to 4-bit integers.
```py
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, TorchAoConfig
from torchao.quantization import Int4WeightOnlyConfig
quantization_config = Int4WeightOnlyConfig(group_size=128)
quantization_config = TorchAoConfig(quant_type=quant_config)
tokenizer = AutoTokenizer.from_pretrained("state-spaces/mamba-2.8b-hf")
model = AutoModelForCausalLM.from_pretrained("state-spaces/mamba-2.8b-hf", torch_dtype=torch.bfloat16, quantization_config=quantization_config, device_map="auto",)
input_ids = tokenizer("Plants create energy through a process known as", return_tensors="pt").to("cuda")
output = model.generate(**input_ids)
print(tokenizer.decode(output[0], skip_special_tokens=True))
```
## Notes
- The current implementation uses the original CUDA kernels. The FlashAttention equivalent implementation is hosted in the [mamba-ssm](https://github.com/state-spaces/mamba) and [causal_conv1d](https://github.com/Dao-AILab/causal-conv1d) repositories. Make sure to install them if your hardware supports it!
- Mamba stacks `mixer` layers which are equivalent to `Attention` layers. You can find the main logic of Mamba in the `MambaMixer` class.

# Mamba 2
[Mamba 2](https://huggingface.co/papers/2405.21060) is based on the state space duality (SSD) framework which connects structured state space models (SSMs) and attention variants. It uses a more efficient SSD algorithm that is 2-8x faster than Mamba and modifies the architecture to enable tensor parallelism and a grouped-value attention (GVA) head structure.

You can find all the original Mamba 2 checkpoints under the [State Space Models](https://huggingface.co/state-spaces) organization, but the examples shown below use [mistralai/Mamba-Codestral-7B-v0.1](https://huggingface.co/mistralai/Mamba-Codestral-7B-v0.1) because a Hugging Face implementation isn't supported yet for the original checkpoints.
## Overview
> [!TIP]
> Click on the Mamba models in the right sidebar for more examples of how to apply Mamba to different language tasks.
The Mamba2 model was proposed in [Transformers are SSMs: Generalized Models and Efficient Algorithms Through Structured State Space Duality](https://arxiv.org/abs/2405.21060) by Tri Dao and Albert Gu. It is a State Space Model similar to Mamba 1, with better performances in a simplified architecture.
The example below demonstrates how to generate text with [`Pipeline`], [`AutoModel`], and from the command line.
hfoptions id="usage">
<hfoption id="Pipeline">
The abstract from the paper is the following:
```python
*While Transformers have been the main architecture behind deep learning's success in language modeling, state-space models (SSMs) such as Mamba have recently been shown to match or outperform Transformers at small to medium scale. We show that these families of models are actually quite closely related, and develop a rich framework of theoretical connections between SSMs and variants of attention, connected through various decompositions of a well-studied class of structured semiseparable matrices. Our state space duality (SSD) framework allows us to design a new architecture (Mamba-2) whose core layer is an a refinement of Mamba's selective SSM that is 2-8X faster, while continuing to be competitive with Transformers on language modeling.*
Tips:
This version should support all implementations of Mamba 2, and in particular [Mamba-2 codestral](https://huggingface.co/mistralai/Mamba-Codestral-7B-v0.1) from Mistral AI. In particular, mamba 2 codestral was released with a number of `groups` equal to 8, which can be thought intuitively as similar to the number of kv heads in an attention-based model.
This model has two different forward passes, `torch_forward` or `cuda_kernels_forward`. The latter uses the original cuda kernels if they are found in your environment, and is slower on the prefill i.e. requires a "warmup run" due to high cpu overhead, see [here](https://github.com/state-spaces/mamba/issues/389#issuecomment-2171755306) and [also here](https://github.com/state-spaces/mamba/issues/355#issuecomment-2147597457). Without compilation, the `torch_forward` implementation is faster by a factor 3 to 4. Further, there are no positional embeddings in this model, but there is an `attention_mask` and a specific logic to mask out hidden states in two places in the case of batched generation, see [here](https://github.com/state-spaces/mamba/issues/66#issuecomment-1863563829) as well. Due to this, in addition to the reimplementation of mamba2 kernels, batched generation and cached generation are expected to have slight discrepancies. Further, the results given by the cuda kernels or the torch forward are expected to be slightly different. The SSM algorithm heavily relies on tensor contractions, which have matmul equivalents but the order of operations is slightly different, making the difference greater at smaller precisions.
Another note, shutdown of hidden states corresponding to padding tokens is done in 2 places and mostly has been tested with left-padding. Right-padding will propagate noise down the line and is not guaranteed to yield satisfactory results. `tokenizer.padding_side = "left"` ensures you are using the correct padding side.

## Notes
- Codestral Mamba has `groups=8` which are similar to the number of kv heads in an attention-based model.
- Codestral Mamba has two different forward passes, `torch_forward` or `cuda_kernels_forward`, and their results are expected to be slightly different.
- `torch_forward` without compilation is 3-4x faster than `cuda_kernels_forward`.
- `cuda_kernels_forward` uses the original CUDA kernels if they're available in your environment. It is slower during prefill because it requires a "warmup run" due to the higher CPU overhead (see [these](https://github.com/state-spaces/mamba/issues/389#issuecomment-2171755306) [comments](https://github.com/state-spaces/mamba/issues/355#issuecomment-2147597457) for more details).

This (and the addition of the reimplemented Mamba 2 kernels) results in a slight discrepancy between batched and cached generation.

# MiniMax
## Overview
The MiniMax-Text-01 model was proposed in [MiniMax-01: Scaling Foundation Models with Lightning Attention](https://arxiv.org/abs/2501.08313) by MiniMax, Aonian Li, Bangwei Gong, Bo Yang, Boji Shan, Chang Liu, Cheng Zhu, Chunhao Zhang, Congchao Guo, Da Chen, Dong Li, Enwei Jiao, Gengxin Li, Guojun Zhang, Haohai Sun, Houze Dong, Jiadai Zhu, Jiaqi Zhuang, Jiayuan Song, Jin Zhu, Jingtao Han, Jingyang Li, Junbin Xie, Junhao Xu, Junjie Yan, Kaishun Zhang, Kecheng Xiao, Kexi Kang, Le Han, Leyang Wang, Lianfei Yu, Liheng Feng, Lin Zheng, Linbo Chai, Long Xing, Meizhi Ju, Mingyuan Chi, Mozhi Zhang, Peikai Huang, Pengcheng Niu, Pengfei Li, Pengyu Zhao, Qi Yang, Qidi Xu, Qiexiang Wang, Qin Wang, Qiuhui Li, Ruitao Leng, Shengmin Shi, Shuqi Yu, Sichen Li, Songquan Zhu, Tao Huang, Tianrun Liang, Weigao Sun, Weixuan Sun, Weiyu Cheng, Wenkai Li, Xiangjun Song, Xiao Su, Xiaodong Han, Xinjie Zhang, Xinzhu Hou, Xu Min, Xun Zou, Xuyang Shen, Yan Gong, Yingjie Zhu, Yipeng Zhou, Yiran Zhong, Yongyi Hu, Yuanxiang Fan, Yue Yu, Yufeng Yang, Yuhao Li, Yunan Huang, Yunji Li, Yunpeng Huang, Yunzhi Xu, Yuxin Mao, Zehan Li, Zekang Li, Zewei Tao, Zewen Ying, Zhaoyang Cong, Zhen Qin, Zhenhua Fan, Zhihang Yu, Zhuo Jiang, Zijia Wu.
The abstract from the paper is the following:
*We introduce MiniMax-01 series, including MiniMax-Text-01 and MiniMax-VL-01, which are comparable to top-tier models while offering superior capabilities in processing longer contexts. The core lies in lightning attention and its efficient scaling. To maximize computational capacity, we integrate it with Mixture of Experts (MoE), creating a model with 32 experts and 456 billion total parameters, of which 45.9 billion are activated for each token. We develop an optimized parallel strategy and highly efficient computation-communication overlap techniques for MoE and lightning attention. This approach enables us to conduct efficient training and inference on models with hundreds of billions of parameters across contexts spanning millions of tokens. The context window of MiniMax-Text-01 can reach up to 1 million tokens during training and extrapolate to 4 million tokens during inference at an affordable cost. Our vision-language model, MiniMax-VL-01 is built through continued training with 512 billion vision-language tokens. Experiments on both standard and in-house benchmarks show that our models match the performance of state-of-the-art models like GPT-4o and Claude-3.5-Sonnet while offering 20-32 times longer context window.*
### Architectural details
MiniMax is a powerful language model with 456 billion total parameters, of which 45.9 billion are activated per token. To better unlock the long context capabilities of the model, MiniMax adopts a hybrid architecture that combines Lightning Attention, Softmax Attention and Mixture-of-Experts (MoE). Leveraging advanced parallel strategies and innovative compute-communication overlap methods—such as Linear Attention Sequence Parallelism Plus (LASP+), varlen ring attention, Expert Tensor Parallel (ETP), etc., MiniMax's training context length is extended to 1 million tokens, and it can handle a context of up to 4 million tokens during the inference. On various academic benchmarks, MiniMax also demonstrates the performance of a top-tier model.
The architecture of MiniMax is briefly described as follows:
- Total Parameters: 456B
- Activated Parameters per Token: 45.9B
- Number Layers: 80
- Hybrid Attention: a softmax attention is positioned after every 7 lightning attention.
- Number of attention heads: 64
- Attention head dimension: 128
- Mixture of Experts:
- Number of experts: 32
- Expert hidden dimension: 9216
- Top-2 routing strategy
- Positional Encoding: Rotary Position Embedding (RoPE) applied to half of the attention head dimension with a base frequency of 10,000,000
- Hidden Size: 6144
- Vocab Size: 200,064

`MiniMax` is released under the MINIMAX MODEL LICENSE AGREEMENT.
## Usage tips
The pre-trained model can be used as follows:
```python
>>> from transformers import AutoModelForCausalLM, AutoTokenizer
>>> model = AutoModelForCausalLM.from_pretrained("MiniMaxAI/MiniMax-Text-01-hf", device_map="auto")
>>> tokenizer = AutoTokenizer.from_pretrained("MiniMaxAI/MiniMax-Text-01-hf")
>>> messages = [
... {"role": "user", "content": "What is your favourite condiment?"},
... {"role": "assistant", "content": "Well, I'm quite partial to a good squeeze of fresh lemon juice. It adds just the right amount of zesty flavour to whatever I'm cooking up in the kitchen!"},
... {"role": "user", "content": "Do you have mayonnaise recipes?"}
... ]
>>> model_inputs = tokenizer.apply_chat_template(messages, return_tensors="pt").to("cuda")
>>> generated_ids = model.generate(model_inputs, max_new_tokens=100, do_sample=True)
>>> tokenizer.batch_decode(generated_ids)[0]
"Mayonnaise can be made as follows: (...)"
```
As can be seen, the instruction-tuned model requires a [chat template](../chat_templating) to be applied to make sure the inputs are prepared in the right format.
## Speeding up MiniMax by using Flash Attention
The code snippets above showcase inference without any optimization tricks. However, one can drastically speed up the model by leveraging [Flash Attention](../perf_train_gpu_one#flash-attention-2), which is a faster implementation of the attention mechanism used inside the model.
First, make sure to install the latest version of Flash Attention 2 to include the sliding window attention feature.
```bash
pip install -U flash-attn --no-build-isolation
```
Make also sure that you have a hardware that is compatible with Flash-Attention 2. Read more about it in the official documentation of the [flash attention repository](https://github.com/Dao-AILab/flash-attention). Make also sure to load your model in half-precision (e.g. `torch.float16`)
To load and run a model using Flash Attention-2, refer to the snippet below:
```python
>>> import torch
>>> from transformers import AutoModelForCausalLM, AutoTokenizer
>>> model = AutoModelForCausalLM.from_pretrained("MiniMaxAI/MiniMax-Text-01-hf", torch_dtype=torch.float16, attn_implementation="flash_attention_2", device_map="auto")
>>> tokenizer = AutoTokenizer.from_pretrained("MiniMaxAI/MiniMax-Text-01-hf")
>>> prompt = "My favourite condiment is"
>>> model_inputs = tokenizer([prompt], return_tensors="pt").to("cuda")
>>> model.to(device)
>>> generated_ids = model.generate(**model_inputs, max_new_tokens=100, do_sample=True)
>>> tokenizer.batch_decode(generated_ids)[0]
"The expected output"
```
### Sliding window Attention
The current implementation supports the sliding window attention mechanism and memory efficient cache management.
To enable sliding window attention, just make sure to have a `flash-attn` version that is compatible with sliding window attention (`>=2.3.0`).
The Flash Attention-2 model uses also a more memory efficient cache slicing mechanism - as recommended per the official implementation of Mistral model that use rolling cache mechanism we keep the cache size fixed (`self.config.sliding_window`), support batched generation only for `padding_side="left"` and use the absolute position of the current token to compute the positional embedding.
## Shrinking down MiniMax using quantization
As the MiniMax model has 456 billion parameters, that would require about 912GB of GPU RAM in half precision (float16), since each parameter is stored in 2 bytes. However, one can shrink down the size of the model using [quantization](../quantization.md). If the model is quantized to 4 bits (or half a byte per parameter), about 228 GB of RAM is required.
Quantizing a model is as simple as passing a `quantization_config` to the model. Below, we'll leverage the bitsandbytes quantization library (but refer to [this page](../quantization.md) for alternative quantization methods):
```python
>>> import torch
>>> from transformers import AutoModelForCausalLM, AutoTokenizer, BitsAndBytesConfig
>>> # specify how to quantize the model
>>> quantization_config = BitsAndBytesConfig(
... load_in_4bit=True,
... bnb_4bit_quant_type="nf4",
... bnb_4bit_compute_dtype="torch.float16",
... )
>>> model = AutoModelForCausalLM.from_pretrained("MiniMaxAI/MiniMax-Text-01-hf", quantization_config=True, device_map="auto")
>>> tokenizer = AutoTokenizer.from_pretrained("MiniMaxAI/MiniMax-Text-01-hf")
>>> prompt = "My favourite condiment is"
>>> messages = [
... {"role": "user", "content": "What is your favourite condiment?"},
... {"role": "assistant", "content": "Well, I'm quite partial to a good squeeze of fresh lemon juice. It adds just the right amount of zesty flavour to whatever I'm cooking up in the kitchen!"},
... {"role": "user", "content": "Do you have mayonnaise recipes?"}
... ]
>>> model_inputs = tokenizer.apply_chat_template(messages, return_tensors="pt").to("cuda")
>>> generated_ids = model.generate(model_inputs, max_new_tokens=100, do_sample=True)
>>> tokenizer.batch_decode(generated_ids)[0]
"The expected output"
```

# MobileNet V1
[MobileNet V1](https://huggingface.co/papers/1704.04861) is a family of efficient convolutional neural networks optimized for on-device or embedded vision tasks. It achieves this efficiency by using depth-wise separable convolutions instead of standard convolutions. The architecture allows for easy trade-offs between latency and accuracy using two main hyperparameters, a width multiplier (alpha) and an image resolution multiplier.

## Overview
> [!TIP]
> Click on the MobileNet V1 models in the right sidebar for more examples of how to apply MobileNet to different vision tasks.
The MobileNet model was proposed in [MobileNets: Efficient Convolutional Neural Networks for Mobile Vision Applications](https://arxiv.org/abs/1704.04861) by Andrew G. Howard, Menglong Zhu, Bo Chen, Dmitry Kalenichenko, Weijun Wang, Tobias Weyand, Marco Andreetto, Hartwig Adam.
The example below demonstrates how to classify an image with [`Pipeline`] or the [`AutoModel`] class.
The abstract from the paper is the following:
*We present a class of efficient models called MobileNets for mobile and embedded vision applications. MobileNets are based on a streamlined architecture that uses depth-wise separable convolutions to build light weight deep neural networks. We introduce two simple global hyper-parameters that efficiently trade off between latency and accuracy. These hyper-parameters allow the model builder to choose the right sized model for their application based on the constraints of the problem. We present extensive experiments on resource and accuracy tradeoffs and show strong performance compared to other popular models on ImageNet classification. We then demonstrate the effectiveness of MobileNets across a wide range of applications and use cases including object detection, finegrain classification, face attributes and large scale geo-localization.*
<hfoptions id="usage">
<hfoption id="Pipeline">
This model was contributed by [matthijs](https://huggingface.co/Matthijs). The original code and weights can be found [here](https://github.com/tensorflow/models/blob/master/research/slim/nets/mobilenet_v1.md).
```python
import torch
from transformers import pipeline
## Usage tips
pipeline = pipeline(
task="image-classification",
model="google/mobilenet_v1_1.0_224",
torch_dtype=torch.float16,
device=0
)
pipeline(images="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg")
```
- The checkpoints are named **mobilenet\_v1\_*depth*\_*size***, for example **mobilenet\_v1\_1.0\_224**, where **1.0** is the depth multiplier (sometimes also referred to as "alpha" or the width multiplier) and **224** is the resolution of the input images the model was trained on.
</hfoption>
<hfoption id="AutoModel">
- Even though the checkpoint is trained on images of specific size, the model will work on images of any size. The smallest supported image size is 32x32.
```python
import torch
import requests
from PIL import Image
from transformers import AutoModelForImageClassification, AutoImageProcessor
- One can use [`MobileNetV1ImageProcessor`] to prepare images for the model.
image_processor = AutoImageProcessor.from_pretrained(
"google/mobilenet_v1_1.0_224",
)
model = AutoModelForImageClassification.from_pretrained(
"google/mobilenet_v1_1.0_224",
)
- The available image classification checkpoints are pre-trained on [ImageNet-1k](https://huggingface.co/datasets/imagenet-1k) (also referred to as ILSVRC 2012, a collection of 1.3 million images and 1,000 classes). However, the model predicts 1001 classes: the 1000 classes from ImageNet plus an extra “background” class (index 0).
url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg"
image = Image.open(requests.get(url, stream=True).raw)
inputs = image_processor(image, return_tensors="pt")
- The original TensorFlow checkpoints use different padding rules than PyTorch, requiring the model to determine the padding amount at inference time, since this depends on the input image size. To use native PyTorch padding behavior, create a [`MobileNetV1Config`] with `tf_padding = False`.
with torch.no_grad():
logits = model(**inputs).logits
predicted_class_id = logits.argmax(dim=-1).item()
Unsupported features:
class_labels = model.config.id2label
predicted_class_label = class_labels[predicted_class_id]
print(f"The predicted class label is: {predicted_class_label}")
```
- The [`MobileNetV1Model`] outputs a globally pooled version of the last hidden state. In the original model it is possible to use a 7x7 average pooling layer with stride 2 instead of global pooling. For larger inputs, this gives a pooled output that is larger than 1x1 pixel. The HuggingFace implementation does not support this.
</hfoption>
</hfoptions>
- It is currently not possible to specify an `output_stride`. For smaller output strides, the original model invokes dilated convolution to prevent the spatial resolution from being reduced further. The output stride of the HuggingFace model is always 32.
<!-- Quantization - Not applicable -->
<!-- Attention Visualization - Not applicable for this model type -->
- The original TensorFlow checkpoints include quantized models. We do not support these models as they include additional "FakeQuantization" operations to unquantize the weights.
- It's common to extract the output from the pointwise layers at indices 5, 11, 12, 13 for downstream purposes. Using `output_hidden_states=True` returns the output from all intermediate layers. There is currently no way to limit this to specific layers.
## Notes
## Resources
- Checkpoint names follow the pattern `mobilenet_v1_{depth_multiplier}_{resolution}`, like `mobilenet_v1_1.0_224`. `1.0` is the depth multiplier and `224` is the image resolution.
- While trained on images of a specific sizes, the model architecture works with images of different sizes (minimum 32x32). The [`MobileNetV1ImageProcessor`] handles the necessary preprocessing.
- MobileNet is pretrained on [ImageNet-1k](https://huggingface.co/datasets/imagenet-1k), a dataset with 1000 classes. However, the model actually predicts 1001 classes. The additional class is an extra "background" class (index 0).
- The original TensorFlow checkpoints determines the padding amount at inference because it depends on the input image size. To use the native PyTorch padding behavior, set `tf_padding=False` in [`MobileNetV1Config`].
```python
from transformers import MobileNetV1Config
A list of official Hugging Face and community (indicated by 🌎) resources to help you get started with MobileNetV1.
config = MobileNetV1Config.from_pretrained("google/mobilenet_v1_1.0_224", tf_padding=True)
```
- The Transformers implementation does not support the following features.
- Uses global average pooling instead of the optional 7x7 average pooling with stride 2. For larger inputs, this gives a pooled output that is larger than a 1x1 pixel.
- Does not support other `output_stride` values (fixed at 32). For smaller `output_strides`, the original implementation uses dilated convolution to prevent spatial resolution from being reduced further. (which would require dilated convolutions).
- `output_hidden_states=True` returns *all* intermediate hidden states. It is not possible to extract the output from specific layers for other downstream purposes.
- Does not include the quantized models from the original checkpoints because they include "FakeQuantization" operations to unquantize the weights.

# MobileNet V2
[MobileNet V2](https://huggingface.co/papers/1801.04381) improves performance on mobile devices with a more efficient architecture. It uses inverted residual blocks and linear bottlenecks to start with a smaller representation of the data, expands it for processing, and shrinks it again to reduce the number of computations. The model also removes non-linearities to maintain accuracy despite its simplified design. Like [MobileNet V1](./mobilenet_v1), it uses depthwise separable convolutions for efficiency.

## Overview

> Click on the MobileNet V2 models in the right sidebar for more examples of how to apply MobileNet to different vision tasks.
The MobileNet model was proposed in [MobileNetV2: Inverted Residuals and Linear Bottlenecks](https://arxiv.org/abs/1801.04381) by Mark Sandler, Andrew Howard, Menglong Zhu, Andrey Zhmoginov, Liang-Chieh Chen.
The abstract from the paper is the following:
The examples below demonstrate how to classify an image with [`Pipeline`] or the [`AutoModel`] class.
*In this paper we describe a new mobile architecture, MobileNetV2, that improves the state of the art performance of mobile models on multiple tasks and benchmarks as well as across a spectrum of different model sizes. We also describe efficient ways of applying these mobile models to object detection in a novel framework we call SSDLite. Additionally, we demonstrate how to build mobile semantic segmentation models through a reduced form of DeepLabv3 which we call Mobile DeepLabv3.*
*The MobileNetV2 architecture is based on an inverted residual structure where the input and output of the residual block are thin bottleneck layers opposite to traditional residual models which use expanded representations in the input an MobileNetV2 uses lightweight depthwise convolutions to filter features in the intermediate expansion layer. Additionally, we find that it is important to remove non-linearities in the narrow layers in order to maintain representational power. We demonstrate that this improves performance and provide an intuition that led to this design. Finally, our approach allows decoupling of the input/output domains from the expressiveness of the transformation, which provides a convenient framework for further analysis. We measure our performance on Imagenet classification, COCO object detection, VOC image segmentation. We evaluate the trade-offs between accuracy, and number of operations measured by multiply-adds (MAdd), as well as the number of parameters.*

<hfoption id="Pipeline">
This model was contributed by [matthijs](https://huggingface.co/Matthijs). The original code and weights can be found [here for the main model](https://github.com/tensorflow/models/tree/master/research/slim/nets/mobilenet) and [here for DeepLabV3+](https://github.com/tensorflow/models/tree/master/research/deeplab).
```python
import torch
from transformers import pipeline
## Usage tips
pipeline = pipeline(
task="image-classification",
model="google/mobilenet_v2_1.4_224",
torch_dtype=torch.float16,
device=0
)
pipeline(images="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg")
```
- The checkpoints are named **mobilenet\_v2\_*depth*\_*size***, for example **mobilenet\_v2\_1.0\_224**, where **1.0** is the depth multiplier (sometimes also referred to as "alpha" or the width multiplier) and **224** is the resolution of the input images the model was trained on.
</hfoption>
<hfoption id="AutoModel">
- Even though the checkpoint is trained on images of specific size, the model will work on images of any size. The smallest supported image size is 32x32.
```python
import torch
import requests
from PIL import Image
from transformers import AutoModelForImageClassification, AutoImageProcessor
- One can use [`MobileNetV2ImageProcessor`] to prepare images for the model.
image_processor = AutoImageProcessor.from_pretrained(
"google/mobilenet_v2_1.4_224",
)
model = AutoModelForImageClassification.from_pretrained(
"google/mobilenet_v2_1.4_224",
)
- The available image classification checkpoints are pre-trained on [ImageNet-1k](https://huggingface.co/datasets/imagenet-1k) (also referred to as ILSVRC 2012, a collection of 1.3 million images and 1,000 classes). However, the model predicts 1001 classes: the 1000 classes from ImageNet plus an extra “background” class (index 0).
url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg"
image = Image.open(requests.get(url, stream=True).raw)
inputs = image_processor(image, return_tensors="pt")
- The segmentation model uses a [DeepLabV3+](https://arxiv.org/abs/1802.02611) head. The available semantic segmentation checkpoints are pre-trained on [PASCAL VOC](http://host.robots.ox.ac.uk/pascal/VOC/).
with torch.no_grad():
logits = model(**inputs).logits
predicted_class_id = logits.argmax(dim=-1).item()
- The original TensorFlow checkpoints use different padding rules than PyTorch, requiring the model to determine the padding amount at inference time, since this depends on the input image size. To use native PyTorch padding behavior, create a [`MobileNetV2Config`] with `tf_padding = False`.
class_labels = model.config.id2label
predicted_class_label = class_labels[predicted_class_id]
print(f"The predicted class label is: {predicted_class_label}")
```
Unsupported features:
</hfoption>
</hfoptions>
- The [`MobileNetV2Model`] outputs a globally pooled version of the last hidden state. In the original model it is possible to use an average pooling layer with a fixed 7x7 window and stride 1 instead of global pooling. For inputs that are larger than the recommended image size, this gives a pooled output that is larger than 1x1. The Hugging Face implementation does not support this.
- The original TensorFlow checkpoints include quantized models. We do not support these models as they include additional "FakeQuantization" operations to unquantize the weights.
## Notes
- It's common to extract the output from the expansion layers at indices 10 and 13, as well as the output from the final 1x1 convolution layer, for downstream purposes. Using `output_hidden_states=True` returns the output from all intermediate layers. There is currently no way to limit this to specific layers.
- Classification checkpoint names follow the pattern `mobilenet_v2_{depth_multiplier}_{resolution}`, like `mobilenet_v2_1.4_224`. `1.4` is the depth multiplier and `224` is the image resolution. Segmentation checkpoint names follow the pattern `deeplabv3_mobilenet_v2_{depth_multiplier}_{resolution}`.
- While trained on images of a specific sizes, the model architecture works with images of different sizes (minimum 32x32). The [`MobileNetV2ImageProcessor`] handles the necessary preprocessing.
- MobileNet is pretrained on [ImageNet-1k](https://huggingface.co/datasets/imagenet-1k), a dataset with 1000 classes. However, the model actually predicts 1001 classes. The additional class is an extra "background" class (index 0).
- The segmentation models use a [DeepLabV3+](https://huggingface.co/papers/1802.02611) head which is often pretrained on datasets like [PASCAL VOC](https://huggingface.co/datasets/merve/pascal-voc).
- The original TensorFlow checkpoints determines the padding amount at inference because it depends on the input image size. To use the native PyTorch padding behavior, set `tf_padding=False` in [`MobileNetV2Config`].
```python
from transformers import MobileNetV2Config
- The DeepLabV3+ segmentation head does not use the final convolution layer from the backbone, but this layer gets computed anyway. There is currently no way to tell [`MobileNetV2Model`] up to which layer it should run.
config = MobileNetV2Config.from_pretrained("google/mobilenet_v2_1.4_224", tf_padding=True)
```
- The Transformers implementation does not support the following features.
- Uses global average pooling instead of the optional 7x7 average pooling with stride 2. For larger inputs, this gives a pooled output that is larger than a 1x1 pixel.
- `output_hidden_states=True` returns *all* intermediate hidden states. It is not possible to extract the output from specific layers for other downstream purposes.
- Does not include the quantized models from the original checkpoints because they include "FakeQuantization" operations to unquantize the weights.
- For segmentation models, the final convolution layer of the backbone is computed even though the DeepLabV3+ head doesn't use it.

## Implementation differences with SwitchTransformers
The biggest difference is the way the tokens are routed. NLLB-MoE uses a `top-2-gate` which means that for each input, only the top two experts are selected based on the
highest predicted probabilities from the gating network, and the remaining experts are ignored. In `SwitchTransformers`, only the top-1 probabilities are computed,
which means that tokens have less probability of being forwarded. Moreover, if a token is not routed to any expert, `SwitchTransformers` still adds its unmodified hidden
states (kind of like a residual connection) while they are masked in `NLLB`'s top-2 routing mechanism.

# OLMo2
[OLMo2](https://huggingface.co/papers/2501.00656) improves on [OLMo](./olmo) by changing the architecture and training recipes of the original models. This includes excluding all biases to improve training stability, non-parametric layer norm, SwiGLU activation function, rotary positional embeddings, and a modified BPE-based tokenizer that masks personal identifiable information. It is pretrained on [Dolma](https://huggingface.co/datasets/allenai/dolma), a dataset of 3T tokens.
## Overview
You can find all the original OLMo2 checkpoints under the [OLMo2](https://huggingface.co/collections/allenai/olmo-2-674117b93ab84e98afc72edc) collection.
The OLMo2 model is the successor of the OLMo model, which was proposed in
[OLMo: Accelerating the Science of Language Models](https://arxiv.org/abs/2402.00838).

The architectural changes from the original OLMo model to this model are:
The example below demonstrates how to generate text with [`Pipeline`], [`AutoModel`] and from the command line.
- RMSNorm is used instead of standard layer norm.
- Norm is applied to attention queries and keys.
- Norm is applied after attention/feedforward layers rather than before.

Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the [Quantization](../quantization/overview) overview for more available quantization backends.
The example below uses [torchao](../quantization/torchao) to only quantize the weights to 4-bits.
```py
#pip install torchao
import torch
from transformers import AutoModelForCausalLM, AutoTokenizer, TorchAoConfig
torchao_config = TorchAoConfig(
"int4_weight_only",
group_size=128
)
tokenizer = AutoTokenizer.from_pretrained(
"allenai/OLMo-2-0425-1B"
)
model = AutoModelForCausalLM.from_pretrained(
"allenai/OLMo-2-0425-1B",
quantization_config=torchao_config,
torch_dtype=torch.bfloat16,
device_map="auto",
attn_implementation="sdpa"
)
input_ids = tokenizer("Plants create energy through a process known as", return_tensors="pt").to(model.device)
output = model.generate(**input_ids, max_length=50, cache_implementation="static")
print(tokenizer.decode(output[0], skip_special_tokens=True))
```
## Notes
- OLMo2 uses RMSNorm instead of standard layer norm. The RMSNorm is applied to attention queries and keys, and it is applied after the attention and feedforward layers rather than before.
- OLMo2 requires Transformers v4.48 or higher.
- Load specific intermediate checkpoints by adding the `revision` parameter to [`~PreTrainedModel.from_pretrained`].
```py
from transformers import AutoModelForCausalLM
model = AutoModelForCausalLM.from_pretrained("allenai/OLMo-2-0425-1B", revision="stage1-step140000-tokens294B")
```

# RoFormer
## Overview
[RoFormer](https://huggingface.co/papers/2104.09864) introduces Rotary Position Embedding (RoPE) to encode token positions by rotating the inputs in 2D space. This allows a model to track absolute positions and model relative relationships. RoPE can scale to longer sequences, account for the natural decay of token dependencies, and works with the more efficient linear self-attention.
The RoFormer model was proposed in [RoFormer: Enhanced Transformer with Rotary Position Embedding](https://arxiv.org/pdf/2104.09864v1.pdf) by Jianlin Su and Yu Lu and Shengfeng Pan and Bo Wen and Yunfeng Liu.
You can find all the RoFormer checkpoints on the [Hub](https://huggingface.co/models?search=roformer).
The abstract from the paper is the following:

*Position encoding in transformer architecture provides supervision for dependency modeling between elements at
different positions in the sequence. We investigate various methods to encode positional information in
transformer-based language models and propose a novel implementation named Rotary Position Embedding(RoPE). The
proposed RoPE encodes absolute positional information with rotation matrix and naturally incorporates explicit relative
position dependency in self-attention formulation. Notably, RoPE comes with valuable properties such as flexibility of
being expand to any sequence lengths, decaying inter-token dependency with increasing relative distances, and
capability of equipping the linear self-attention with relative position encoding. As a result, the enhanced
transformer with rotary position embedding, or RoFormer, achieves superior performance in tasks with long texts. We
release the theoretical analysis along with some preliminary experiment results on Chinese data. The undergoing
experiment for English benchmark will soon be updated.*
The example below demonstrates how to predict the `[MASK]` token with [`Pipeline`], [`AutoModel`], and from the command line.

# Swin Transformer
[Swin Transformer](https://huggingface.co/papers/2103.14030) is a hierarchical vision transformer. Images are processed in patches and windowed self-attention is used to capture local information. These windows are shifted across the image to allow for cross-window connections, capturing global information more efficiently. This hierarchical approach with shifted windows allows the Swin Transformer to process images effectively at different scales and achieve linear computational complexity relative to image size, making it a versatile backbone for various vision tasks like image classification and object detection.

The abstract from the paper is the following:
<hfoptions id="usage">
<hfoption id="Pipeline">
*This paper presents a new vision Transformer, called Swin Transformer, that capably serves as a general-purpose backbone
for computer vision. Challenges in adapting Transformer from language to vision arise from differences between the two domains,
such as large variations in the scale of visual entities and the high resolution of pixels in images compared to words in text.
To address these differences, we propose a hierarchical Transformer whose representation is computed with \bold{S}hifted
\bold{win}dows. The shifted windowing scheme brings greater efficiency by limiting self-attention computation to non-overlapping
local windows while also allowing for cross-window connection. This hierarchical architecture has the flexibility to model at
various scales and has linear computational complexity with respect to image size. These qualities of Swin Transformer make it
compatible with a broad range of vision tasks, including image classification (87.3 top-1 accuracy on ImageNet-1K) and dense
prediction tasks such as object detection (58.7 box AP and 51.1 mask AP on COCO test-dev) and semantic segmentation
(53.5 mIoU on ADE20K val). Its performance surpasses the previous state-of-the-art by a large margin of +2.7 box AP and
+2.6 mask AP on COCO, and +3.2 mIoU on ADE20K, demonstrating the potential of Transformer-based models as vision backbones.
The hierarchical design and the shifted window approach also prove beneficial for all-MLP architectures.*

# Swin Transformer V2
[Swin Transformer V2](https://huggingface.co/papers/2111.09883) is a 3B parameter model that focuses on how to scale a vision model to billions of parameters. It introduces techniques like residual-post-norm combined with cosine attention for improved training stability, log-spaced continuous position bias to better handle varying image resolutions between pre-training and fine-tuning, and a new pre-training method (SimMIM) to reduce the need for large amounts of labeled data. These improvements enable efficiently training very large models (up to 3 billion parameters) capable of processing high-resolution images.

The abstract from the paper is the following:
```py
import torch
from transformers import pipeline
*Large-scale NLP models have been shown to significantly improve the performance on language tasks with no signs of saturation. They also demonstrate amazing few-shot capabilities like that of human beings. This paper aims to explore large-scale models in computer vision. We tackle three major issues in training and application of large vision models, including training instability, resolution gaps between pre-training and fine-tuning, and hunger on labelled data. Three main techniques are proposed: 1) a residual-post-norm method combined with cosine attention to improve training stability; 2) A log-spaced continuous position bias method to effectively transfer models pre-trained using low-resolution images to downstream tasks with high-resolution inputs; 3) A self-supervised pre-training method, SimMIM, to reduce the needs of vast labeled images. Through these techniques, this paper successfully trained a 3 billion-parameter Swin Transformer V2 model, which is the largest dense vision model to date, and makes it capable of training with images of up to 1,536×1,536 resolution. It set new performance records on 4 representative vision tasks, including ImageNet-V2 image classification, COCO object detection, ADE20K semantic segmentation, and Kinetics-400 video action classification. Also note our training is much more efficient than that in Google's billion-level visual models, which consumes 40 times less labelled data and 40 times less training time.*

# ViTMAE
[ViTMAE](https://huggingface.co/papers/2111.06377) is a self-supervised vision model that is pretrained by masking large portions of an image (~75%). An encoder processes the visible image patches and a decoder reconstructs the missing pixels from the encoded patches and mask tokens. After pretraining, the encoder can be reused for downstream tasks like image classification or object detection — often outperforming models trained with supervised learning.

## Overview
The ViTMAE model was proposed in [Masked Autoencoders Are Scalable Vision Learners](https://arxiv.org/abs/2111.06377v2) by Kaiming He, Xinlei Chen, Saining Xie, Yanghao Li,
Piotr Dollár, Ross Girshick. The paper shows that, by pre-training a Vision Transformer (ViT) to reconstruct pixel values for masked patches, one can get results after
fine-tuning that outperform supervised pre-training.
The abstract from the paper is the following:
*This paper shows that masked autoencoders (MAE) are scalable self-supervised learners for computer vision. Our MAE approach is simple: we mask random patches of the
input image and reconstruct the missing pixels. It is based on two core designs. First, we develop an asymmetric encoder-decoder architecture, with an encoder that operates
only on the visible subset of patches (without mask tokens), along with a lightweight decoder that reconstructs the original image from the latent representation and mask
tokens. Second, we find that masking a high proportion of the input image, e.g., 75%, yields a nontrivial and meaningful self-supervisory task. Coupling these two designs
enables us to train large models efficiently and effectively: we accelerate training (by 3x or more) and improve accuracy. Our scalable approach allows for learning high-capacity
models that generalize well: e.g., a vanilla ViT-Huge model achieves the best accuracy (87.8%) among methods that use only ImageNet-1K data. Transfer performance in downstream
tasks outperforms supervised pre-training and shows promising scaling behavior.*

- MAE (masked auto encoding) is a method for self-supervised pre-training of Vision Transformers (ViTs). The pre-training objective is relatively simple:
by masking a large portion (75%) of the image patches, the model must reconstruct raw pixel values. One can use [`ViTMAEForPreTraining`] for this purpose.
- After pre-training, one "throws away" the decoder used to reconstruct pixels, and one uses the encoder for fine-tuning/linear probing. This means that after
fine-tuning, one can directly plug in the weights into a [`ViTForImageClassification`].
- One can use [`ViTImageProcessor`] to prepare images for the model. See the code examples for more info.
- Note that the encoder of MAE is only used to encode the visual patches. The encoded patches are then concatenated with mask tokens, which the decoder (which also
consists of Transformer blocks) takes as input. Each mask token is a shared, learned vector that indicates the presence of a missing patch to be predicted. Fixed
sin/cos position embeddings are added both to the input of the encoder and the decoder.
- For a visual understanding of how MAEs work you can check out this [post](https://keras.io/examples/vision/masked_image_modeling/).

### Using Scaled Dot Product Attention (SDPA)
url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg"
image = Image.open(requests.get(url, stream=True).raw)
PyTorch includes a native scaled dot-product attention (SDPA) operator as part of `torch.nn.functional`. This function
encompasses several implementations that can be applied depending on the inputs and the hardware in use. See the
[official documentation](https://pytorch.org/docs/stable/generated/torch.nn.functional.scaled_dot_product_attention.html)
or the [GPU Inference](https://huggingface.co/docs/transformers/main/en/perf_infer_gpu_one#pytorch-scaled-dot-product-attention)
page for more information.
processor = ViTImageProcessor.from_pretrained("facebook/vit-mae-base")
inputs = processor(image, return_tensors="pt")
inputs = {k: v.to("cuda") for k, v in inputs.items()}
SDPA is used by default for `torch>=2.1.1` when an implementation is available, but you may also set
`attn_implementation="sdpa"` in `from_pretrained()` to explicitly request SDPA to be used.
model = ViTMAEForPreTraining.from_pretrained("facebook/vit-mae-base", attn_implementation="sdpa").to("cuda")
with torch.no_grad():
outputs = model(**inputs)
reconstruction = outputs.logits
```
from transformers import ViTMAEModel
model = ViTMAEModel.from_pretrained("facebook/vit-mae-base", attn_implementation="sdpa", torch_dtype=torch.float16)
...
```
</hfoption>
</hfoptions>
For the best speedups, we recommend loading the model in half-precision (e.g. `torch.float16` or `torch.bfloat16`).
## Notes
- ViTMAE is typically used in two stages. Self-supervised pretraining with [`ViTMAEForPreTraining`], and then discarding the decoder and fine-tuning the encoder. After fine-tuning, the weights can be plugged into a model like [`ViTForImageClassification`].
- Use [`ViTImageProcessor`] for input preparation.
On a local benchmark (A100-40GB, PyTorch 2.3.0, OS Ubuntu 22.04) with `float32` and `facebook/vit-mae-base` model, we saw the following speedups during inference.
| Batch size | Average inference time (ms), eager mode | Average inference time (ms), sdpa model | Speed up, Sdpa / Eager (x) |

# ZoeDepth
[ZoeDepth](https://huggingface.co/papers/2302.12288) is a depth estimation model that combines the generalization performance of relative depth estimation (how far objects are from each other) and metric depth estimation (precise depth measurement on metric scale) from a single image. It is pre-trained on 12 datasets using relative depth and 2 datasets (NYU Depth v2 and KITTI) for metric accuracy. A lightweight head with a metric bin module for each domain is used, and during inference, it automatically selects the appropriate head for each input image with a latent classifier.

## Overview
The ZoeDepth model was proposed in [ZoeDepth: Zero-shot Transfer by Combining Relative and Metric Depth](https://arxiv.org/abs/2302.12288) by Shariq Farooq Bhat, Reiner Birkl, Diana Wofk, Peter Wonka, Matthias Müller. ZoeDepth extends the [DPT](dpt) framework for metric (also called absolute) depth estimation. ZoeDepth is pre-trained on 12 datasets using relative depth and fine-tuned on two domains (NYU and KITTI) using metric depth. A lightweight head is used with a novel bin adjustment design called metric bins module for each domain. During inference, each input image is automatically routed to the appropriate head using a latent classifier.
The abstract from the paper is the following:
*This paper tackles the problem of depth estimation from a single image. Existing work either focuses on generalization performance disregarding metric scale, i.e. relative depth estimation, or state-of-the-art results on specific datasets, i.e. metric depth estimation. We propose the first approach that combines both worlds, leading to a model with excellent generalization performance while maintaining metric scale. Our flagship model, ZoeD-M12-NK, is pre-trained on 12 datasets using relative depth and fine-tuned on two datasets using metric depth. We use a lightweight head with a novel bin adjustment design called metric bins module for each domain. During inference, each input image is automatically routed to the appropriate head using a latent classifier. Our framework admits multiple configurations depending on the datasets used for relative depth pre-training and metric fine-tuning. Without pre-training, we can already significantly improve the state of the art (SOTA) on the NYU Depth v2 indoor dataset. Pre-training on twelve datasets and fine-tuning on the NYU Depth v2 indoor dataset, we can further improve SOTA for a total of 21% in terms of relative absolute error (REL). Finally, ZoeD-M12-NK is the first model that can jointly train on multiple datasets (NYU Depth v2 and KITTI) without a significant drop in performance and achieve unprecedented zero-shot generalization performance to eight unseen datasets from both indoor and outdoor domains.*

<hfoption id="Pipeline">
## Usage tips
```py
import requests
import torch
from transformers import pipeline
from PIL import Image
- ZoeDepth is an absolute (also called metric) depth estimation model, unlike DPT which is a relative depth estimation model. This means that ZoeDepth is able to estimate depth in metric units like meters.
url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg"
image = Image.open(requests.get(url, stream=True).raw)
pipeline = pipeline(
task="depth-estimation",
model="Intel/zoedepth-nyu-kitti",
torch_dtype=torch.float16,
device=0
)
results = pipeline(image)
results["depth"]
The easiest to perform inference with ZoeDepth is by leveraging the [pipeline API](../main_classes/pipelines.md):
```python
>>> from transformers import pipeline
>>> from PIL import Image
>>> import requests
>>> url = "http://images.cocodataset.org/val2017/000000039769.jpg"
>>> image = Image.open(requests.get(url, stream=True).raw)
>>> pipe = pipeline(task="depth-estimation", model="Intel/zoedepth-nyu-kitti")
>>> result = pipe(image)
>>> depth = result["depth"]
```
</hfoption>
<hfoption id="AutoModel">
Alternatively, one can also perform inference using the classes:
```py
import torch
import requests
from PIL import Image
from transformers import AutoModelForDepthEstimation, AutoImageProcessor
```python
>>> from transformers import AutoImageProcessor, ZoeDepthForDepthEstimation
>>> import torch
>>> import numpy as np
>>> from PIL import Image
>>> import requests
image_processor = AutoImageProcessor.from_pretrained(
"Intel/zoedepth-nyu-kitti"
)
model = AutoModelForDepthEstimation.from_pretrained(
"Intel/zoedepth-nyu-kitti",
device_map="auto"
)
url = "https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg"
image = Image.open(requests.get(url, stream=True).raw)
inputs = image_processor(image, return_tensors="pt").to("cuda")
>>> url = "http://images.cocodataset.org/val2017/000000039769.jpg"
>>> image = Image.open(requests.get(url, stream=True).raw)
with torch.no_grad():
outputs = model(inputs)
>>> image_processor = AutoImageProcessor.from_pretrained("Intel/zoedepth-nyu-kitti")
>>> model = ZoeDepthForDepthEstimation.from_pretrained("Intel/zoedepth-nyu-kitti")
# interpolate to original size and visualize the prediction
## ZoeDepth dynamically pads the input image, so pass the original image size as argument
## to `post_process_depth_estimation` to remove the padding and resize to original dimensions.
post_processed_output = image_processor.post_process_depth_estimation(
outputs,
source_sizes=[(image.height, image.width)],
)
>>> # prepare image for the model
>>> inputs = image_processor(images=image, return_tensors="pt")
predicted_depth = post_processed_output[0]["predicted_depth"]
depth = (predicted_depth - predicted_depth.min()) / (predicted_depth.max() - predicted_depth.min())
depth = depth.detach().cpu().numpy() * 255
Image.fromarray(depth.astype("uint8"))
>>> with torch.no_grad():
... outputs = model(inputs)
>>> # interpolate to original size and visualize the prediction
>>> ## ZoeDepth dynamically pads the input image. Thus we pass the original image size as argument
>>> ## to `post_process_depth_estimation` to remove the padding and resize to original dimensions.
>>> post_processed_output = image_processor.post_process_depth_estimation(
... outputs,
... source_sizes=[(image.height, image.width)],
... )
>>> predicted_depth = post_processed_output[0]["predicted_depth"]
>>> depth = (predicted_depth - predicted_depth.min()) / (predicted_depth.max() - predicted_depth.min())
>>> depth = depth.detach().cpu().numpy() * 255
>>> depth = Image.fromarray(depth.astype("uint8"))

# Environment Variables
## HF_ENABLE_PARALLEL_LOADING
By default this is disabled. Enables the loading of torch and safetensor based weights to be loaded in parallel. Can decrease the time to load large models significantly, often times producing speed ups around ~50%.
Can be set to a string equal to `"false"` or `"true"`. e.g. `os.environ["HF_ENABLE_PARALLEL_LOADING"] = "true"`.
e.g. `facebook/opt-30b` on an AWS EC2 g4dn.metal instance can be made to load in ~30s with this enabled vs ~55s without it.
Profile before committing to using this environment variable, this will not produce speed ups for smaller models.
```py
import os
os.environ["HF_ENABLE_PARALLEL_LOADING"] = "true"
from transformers import pipeline
model = pipeline(task="text-generation", model="facebook/opt-30b", device_map="auto")
```
## HF_PARALLEL_LOADING_WORKERS
Determines how many threads should be used when parallel loading is enabled. Default is `8`.
If the number of files that are being loaded is less than the number of threads specified, the number that is actually spawned will be equal to the number of files.
e.g. If you specify 8 workers, and there are only 2 files, only 2 workers will be spawned.
Tune as you see fit.
```py
import os
os.environ["HF_ENABLE_PARALLEL_LOADING"] = "true"
os.environ["HF_PARALLEL_LOADING_WORKERS"] = "4"
from transformers import pipeline
model = pipeline(task="text-generation", model="facebook/opt-30b", device_map="auto")
```

# Sequence classification

<Youtube id="dKE8SIt9C-w"/>
セマンティック セグメンテーションでは、画像の個々のピクセルにラベルまたはクラスを割り当てます。セグメンテーションにはいくつかのタイプがありますが、セマンティック セグメンテーションの場合、同じオブジェクトの一意のインスタンス間の区別は行われません。両方のオブジェクトに同じラベルが付けられます (たとえば、「car-1」と「car-2」の代わりに「car」)。セマンティック セグメンテーションの一般的な現実世界のアプリケーションには、歩行者や重要な交通情報を識別するための自動運転車のトレーニング、医療画像内の細胞と異常の識別、衛星画像からの環境変化の監視などが含まれます。
このガイドでは、次の方法を説明します。
1. [SceneParse150](https://huggingface.co/datasets/scene_parse_150) データセットの [SegFormer](https://huggingface.co/docs/transformers/main/en/model_doc/segformer#segformer) を微調整します。
2. 微調整したモデルを推論に使用します。
<Tip>
このタスクと互換性のあるすべてのアーキテクチャとチェックポイントを確認するには、[タスクページ](https://huggingface.co/tasks/text-classification) を確認することをお勧めします。
</Tip>
始める前に、必要なライブラリがすべてインストールされていることを確認してください。
```bash
pip install -q datasets transformers evaluate
```
モデルをアップロードしてコミュニティと共有できるように、Hugging Face アカウントにログインすることをお勧めします。プロンプトが表示されたら、トークンを入力してログインします。
```py
>>> from huggingface_hub import notebook_login
>>> notebook_login()
```
## Load SceneParse150 dataset
まず、SceneParse150 データセットの小さいサブセットを 🤗 データセット ライブラリから読み込みます。これにより、完全なデータセットのトレーニングにさらに時間を費やす前に、実験してすべてが機能することを確認する機会が得られます。
```py
>>> from datasets import load_dataset
>>> ds = load_dataset("scene_parse_150", split="train[:50]")
```
[`~datasets.Dataset.train_test_split`] メソッドを使用して、データセットの `train` 分割をトレイン セットとテスト セットに分割します。
```py
>>> ds = ds.train_test_split(test_size=0.2)
>>> train_ds = ds["train"]
>>> test_ds = ds["test"]
```
次に、例を見てみましょう。
```py
>>> train_ds[0]
{'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=512x683 at 0x7F9B0C201F90>,
'annotation': <PIL.PngImagePlugin.PngImageFile image mode=L size=512x683 at 0x7F9B0C201DD0>,
'scene_category': 368}
```
- `image`: シーンの PIL イメージ。
- `annotation`: セグメンテーション マップの PIL イメージ。モデルのターゲットでもあります。
- `scene_category`: 「キッチン」や「オフィス」などの画像シーンを説明するカテゴリ ID。このガイドでは、「image」と「annotation」のみが必要になります。どちらも PIL イメージです。
また、ラベル ID をラベル クラスにマップする辞書を作成することもできます。これは、後でモデルを設定するときに役立ちます。ハブからマッピングをダウンロードし、`id2label` および `label2id` ディクショナリを作成します。
```py
>>> import json
>>> from pathlib import Path
>>> from huggingface_hub import hf_hub_download
>>> repo_id = "huggingface/label-files"
>>> filename = "ade20k-id2label.json"
>>> id2label = json.loads(Path(hf_hub_download(repo_id, filename, repo_type="dataset")).read_text())
>>> id2label = {int(k): v for k, v in id2label.items()}
>>> label2id = {v: k for k, v in id2label.items()}
>>> num_labels = len(id2label)
```
## Preprocess
次のステップでは、SegFormer 画像プロセッサをロードして、モデルの画像と注釈を準備します。このデータセットのような一部のデータセットは、バックグラウンド クラスとしてゼロインデックスを使用します。ただし、実際には背景クラスは 150 個のクラスに含まれていないため、`do_reduce_labels=True`を設定してすべてのラベルから 1 つを引く必要があります。ゼロインデックスは `255` に置き換えられるため、SegFormer の損失関数によって無視されます。
```py
>>> from transformers import AutoImageProcessor
>>> checkpoint = "nvidia/mit-b0"
>>> image_processor = AutoImageProcessor.from_pretrained(checkpoint, do_reduce_labels=True)
```
<frameworkcontent>
<pt>
モデルを過学習に対してより堅牢にするために、画像データセットにいくつかのデータ拡張を適用するのが一般的です。このガイドでは、[torchvision](https://pytorch.org) の [`ColorJitter`](https://pytorch.org/vision/stable/generated/torchvision.transforms.ColorJitter.html) 関数を使用します。 /vision/stable/index.html) を使用して画像の色のプロパティをランダムに変更しますが、任意の画像ライブラリを使用することもできます。
```py
>>> from torchvision.transforms import ColorJitter
>>> jitter = ColorJitter(brightness=0.25, contrast=0.25, saturation=0.25, hue=0.1)
```
次に、モデルの画像と注釈を準備するための 2 つの前処理関数を作成します。これらの関数は、画像を`pixel_values`に変換し、注釈を`labels`に変換します。トレーニング セットの場合、画像を画像プロセッサに提供する前に`jitter`が適用されます。テスト セットの場合、テスト中にデータ拡張が適用されないため、画像プロセッサは`images`を切り取って正規化し、`labels` のみを切り取ります。
```py
>>> def train_transforms(example_batch):
... images = [jitter(x) for x in example_batch["image"]]
... labels = [x for x in example_batch["annotation"]]
... inputs = image_processor(images, labels)
... return inputs
>>> def val_transforms(example_batch):
... images = [x for x in example_batch["image"]]
... labels = [x for x in example_batch["annotation"]]
... inputs = image_processor(images, labels)
... return inputs
```
データセット全体に`jitter`を適用するには、🤗 Datasets [`~datasets.Dataset.set_transform`] 関数を使用します。変換はオンザフライで適用されるため、高速で消費するディスク容量が少なくなります。
```py
>>> train_ds.set_transform(train_transforms)
>>> test_ds.set_transform(val_transforms)
```
</pt>
</frameworkcontent>
<frameworkcontent>
<tf>
モデルを過学習に対してより堅牢にするために、画像データセットにいくつかのデータ拡張を適用するのが一般的です。
このガイドでは、[`tf.image`](https://www.tensorflow.org/api_docs/python/tf/image) を使用して画像の色のプロパティをランダムに変更しますが、任意のプロパティを使用することもできます。画像
好きな図書館。
2 つの別々の変換関数を定義します。
- 画像拡張を含むトレーニング データ変換
- 🤗 Transformers のコンピューター ビジョン モデルはチャネル優先のレイアウトを想定しているため、画像を転置するだけの検証データ変換
```py
>>> import tensorflow as tf
>>> def aug_transforms(image):
... image = tf.keras.utils.img_to_array(image)
... image = tf.image.random_brightness(image, 0.25)
... image = tf.image.random_contrast(image, 0.5, 2.0)
... image = tf.image.random_saturation(image, 0.75, 1.25)
... image = tf.image.random_hue(image, 0.1)
... image = tf.transpose(image, (2, 0, 1))
... return image
>>> def transforms(image):
... image = tf.keras.utils.img_to_array(image)
... image = tf.transpose(image, (2, 0, 1))
... return image
```
次に、モデルの画像と注釈のバッチを準備する 2 つの前処理関数を作成します。これらの機能が適用されます
画像変換を行い、以前にロードされた `image_processor` を使用して画像を `pixel_values` に変換し、
`labels`への注釈。 `ImageProcessor` は、画像のサイズ変更と正規化も処理します。
```py
>>> def train_transforms(example_batch):
... images = [aug_transforms(x.convert("RGB")) for x in example_batch["image"]]
... labels = [x for x in example_batch["annotation"]]
... inputs = image_processor(images, labels)
... return inputs
>>> def val_transforms(example_batch):
... images = [transforms(x.convert("RGB")) for x in example_batch["image"]]
... labels = [x for x in example_batch["annotation"]]
... inputs = image_processor(images, labels)
... return inputs
```
データセット全体に前処理変換を適用するには、🤗 Datasets [`~datasets.Dataset.set_transform`] 関数を使用します。
変換はオンザフライで適用されるため、高速で消費するディスク容量が少なくなります。
```py
>>> train_ds.set_transform(train_transforms)
>>> test_ds.set_transform(val_transforms)
```
</tf>
</frameworkcontent>
## Evaluate
トレーニング中にメトリクスを含めると、多くの場合、モデルのパフォーマンスを評価するのに役立ちます。 🤗 [Evaluate](https://huggingface.co/docs/evaluate/index) ライブラリを使用して、評価メソッドをすばやくロードできます。このタスクでは、[Mean Intersection over Union](https://huggingface.co/spaces/evaluate-metric/accuracy) (IoU) メトリックをロードします (🤗 Evaluate [クイック ツアー](https://huggingface.co) を参照してください) /docs/evaluate/a_quick_tour) を参照して、メトリクスをロードして計算する方法の詳細を確認してください)。
```py
>>> import evaluate
>>> metric = evaluate.load("mean_iou")
```
次に、メトリクスを [`~evaluate.EvaluationModule.compute`] する関数を作成します。予測を次のように変換する必要があります
最初にロジットを作成し、次に [`~evaluate.EvaluationModule.compute`] を呼び出す前にラベルのサイズに一致するように再形成します。
<frameworkcontent>
<pt>
```py
>>> import numpy as np
>>> import torch
>>> from torch import nn
>>> def compute_metrics(eval_pred):
... with torch.no_grad():
... logits, labels = eval_pred
... logits_tensor = torch.from_numpy(logits)
... logits_tensor = nn.functional.interpolate(
... logits_tensor,
... size=labels.shape[-2:],
... mode="bilinear",
... align_corners=False,
... ).argmax(dim=1)
... pred_labels = logits_tensor.detach().cpu().numpy()
... metrics = metric.compute(
... predictions=pred_labels,
... references=labels,
... num_labels=num_labels,
... ignore_index=255,
... reduce_labels=False,
... )
... for key, value in metrics.items():
... if type(value) is np.ndarray:
... metrics[key] = value.tolist()
... return metrics
```
</pt>
</frameworkcontent>
<frameworkcontent>
<tf>
```py
>>> def compute_metrics(eval_pred):
... logits, labels = eval_pred
... logits = tf.transpose(logits, perm=[0, 2, 3, 1])
... logits_resized = tf.image.resize(
... logits,
... size=tf.shape(labels)[1:],
... method="bilinear",
... )
... pred_labels = tf.argmax(logits_resized, axis=-1)
... metrics = metric.compute(
... predictions=pred_labels,
... references=labels,
... num_labels=num_labels,
... ignore_index=-1,
... reduce_labels=image_processor.do_reduce_labels,
... )
... per_category_accuracy = metrics.pop("per_category_accuracy").tolist()
... per_category_iou = metrics.pop("per_category_iou").tolist()
... metrics.update({f"accuracy_{id2label[i]}": v for i, v in enumerate(per_category_accuracy)})
... metrics.update({f"iou_{id2label[i]}": v for i, v in enumerate(per_category_iou)})
... return {"val_" + k: v for k, v in metrics.items()}
```
</tf>
</frameworkcontent>
これで`compute_metrics`関数の準備が整いました。トレーニングをセットアップするときにこの関数に戻ります。
## Train
<frameworkcontent>
<pt>
<Tip>
[`Trainer`] を使用したモデルの微調整に慣れていない場合は、[こちら](../training#finetune-with-trainer) の基本的なチュートリアルをご覧ください。
</Tip>
これでモデルのトレーニングを開始する準備が整いました。 [`AutoModelForSemanticSegmentation`] を使用して SegFormer をロードし、ラベル ID とラベル クラス間のマッピングをモデルに渡します。
```py
>>> from transformers import AutoModelForSemanticSegmentation, TrainingArguments, Trainer
>>> model = AutoModelForSemanticSegmentation.from_pretrained(checkpoint, id2label=id2label, label2id=label2id)
```
この時点で残っている手順は次の 3 つだけです。
1. [`TrainingArguments`] でトレーニング ハイパーパラメータを定義します。 `image` 列が削除されるため、未使用の列を削除しないことが重要です。 `image` 列がないと、`pixel_values` を作成できません。この動作を防ぐには、`remove_unused_columns=False`を設定してください。他に必要なパラメータは、モデルの保存場所を指定する `output_dir` だけです。 `push_to_hub=True`を設定して、このモデルをハブにプッシュします (モデルをアップロードするには、Hugging Face にサインインする必要があります)。各エポックの終了時に、[`Trainer`] は IoU メトリックを評価し、トレーニング チェックポイントを保存します。
2. トレーニング引数を、モデル、データセット、トークナイザー、データ照合器、および `compute_metrics` 関数とともに [`Trainer`] に渡します。
3. [`~Trainer.train`] を呼び出してモデルを微調整します。
```py
>>> training_args = TrainingArguments(
... output_dir="segformer-b0-scene-parse-150",
... learning_rate=6e-5,
... num_train_epochs=50,
... per_device_train_batch_size=2,
... per_device_eval_batch_size=2,
... save_total_limit=3,
... eval_strategy="steps",
... save_strategy="steps",
... save_steps=20,
... eval_steps=20,
... logging_steps=1,
... eval_accumulation_steps=5,
... remove_unused_columns=False,
... push_to_hub=True,
... )
>>> trainer = Trainer(
... model=model,
... args=training_args,
... train_dataset=train_ds,
... eval_dataset=test_ds,
... compute_metrics=compute_metrics,
... )
>>> trainer.train()
```
トレーニングが完了したら、 [`~transformers.Trainer.push_to_hub`] メソッドを使用してモデルをハブに共有し、誰もがモデルを使用できるようにします。
```py
>>> trainer.push_to_hub()
```
</pt>
</frameworkcontent>
<frameworkcontent>
<tf>
<Tip>
Keras を使用したモデルの微調整に慣れていない場合は、まず [基本チュートリアル](./training#train-a-tensorflow-model-with-keras) を確認してください。
</Tip>
TensorFlow でモデルを微調整するには、次の手順に従います。
1. トレーニングのハイパーパラメータを定義し、オプティマイザーと学習率スケジュールを設定します。
2. 事前トレーニングされたモデルをインスタンス化します。
3. 🤗 データセットを `tf.data.Dataset` に変換します。
4. モデルをコンパイルします。
5. コールバックを追加してメトリクスを計算し、モデルを 🤗 Hub にアップロードします
6. `fit()` メソッドを使用してトレーニングを実行します。
まず、ハイパーパラメーター、オプティマイザー、学習率スケジュールを定義します。
```py
>>> from transformers import create_optimizer
>>> batch_size = 2
>>> num_epochs = 50
>>> num_train_steps = len(train_ds) * num_epochs
>>> learning_rate = 6e-5
>>> weight_decay_rate = 0.01
>>> optimizer, lr_schedule = create_optimizer(
... init_lr=learning_rate,
... num_train_steps=num_train_steps,
... weight_decay_rate=weight_decay_rate,
... num_warmup_steps=0,
... )
```
次に、ラベル マッピングとともに [`TFAutoModelForSemanticSegmentation`] を使用して SegFormer をロードし、それをコンパイルします。
オプティマイザ。 Transformers モデルにはすべてデフォルトのタスク関連の損失関数があるため、次の場合を除き、損失関数を指定する必要はないことに注意してください。
```py
>>> from transformers import TFAutoModelForSemanticSegmentation
>>> model = TFAutoModelForSemanticSegmentation.from_pretrained(
... checkpoint,
... id2label=id2label,
... label2id=label2id,
... )
>>> model.compile(optimizer=optimizer) # No loss argument!
```
[`~datasets.Dataset.to_tf_dataset`] と [`DefaultDataCollator`] を使用して、データセットを `tf.data.Dataset` 形式に変換します。
```py
>>> from transformers import DefaultDataCollator
>>> data_collator = DefaultDataCollator(return_tensors="tf")
>>> tf_train_dataset = train_ds.to_tf_dataset(
... columns=["pixel_values", "label"],
... shuffle=True,
... batch_size=batch_size,
... collate_fn=data_collator,
... )
>>> tf_eval_dataset = test_ds.to_tf_dataset(
... columns=["pixel_values", "label"],
... shuffle=True,
... batch_size=batch_size,
... collate_fn=data_collator,
... )
```
予測から精度を計算し、モデルを 🤗 ハブにプッシュするには、[Keras callbacks](../main_classes/keras_callbacks) を使用します。
`compute_metrics` 関数を [`KerasMetricCallback`] に渡します。
そして [`PushToHubCallback`] を使用してモデルをアップロードします。
```py
>>> from transformers.keras_callbacks import KerasMetricCallback, PushToHubCallback
>>> metric_callback = KerasMetricCallback(
... metric_fn=compute_metrics, eval_dataset=tf_eval_dataset, batch_size=batch_size, label_cols=["labels"]
... )
>>> push_to_hub_callback = PushToHubCallback(output_dir="scene_segmentation", image_processor=image_processor)
>>> callbacks = [metric_callback, push_to_hub_callback]
```
ついに、モデルをトレーニングする準備が整いました。`fit()`トレーニングおよび検証データセット、エポック数、
モデルを微調整するためのコールバック:
```py
>>> model.fit(
... tf_train_dataset,
... validation_data=tf_eval_dataset,
... callbacks=callbacks,
... epochs=num_epochs,
... )
```
おめでとう!モデルを微調整し、🤗 Hub で共有しました。これで推論に使用できるようになりました。
</tf>
</frameworkcontent>
## Inference
モデルを微調整したので、それを推論に使用できるようになりました。
推論のために画像をロードします。
```py
>>> image = ds[0]["image"]
>>> image
```
<div class="flex justify-center">
<img src="https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/semantic-seg-image.png" alt="Image of bedroom"/>
</div>
<frameworkcontent>
<pt>
推論用に微調整されたモデルを試す最も簡単な方法は、それを [`pipeline`] で使用することです。モデルを使用して画像セグメンテーション用の `pipeline` をインスタンス化し、それに画像を渡します。
```py
>>> from transformers import pipeline
>>> segmenter = pipeline("image-segmentation", model="my_awesome_seg_model")
>>> segmenter(image)
[{'score': None,
'label': 'wall',
'mask': <PIL.Image.Image image mode=L size=640x427 at 0x7FD5B2062690>},
{'score': None,
'label': 'sky',
'mask': <PIL.Image.Image image mode=L size=640x427 at 0x7FD5B2062A50>},
{'score': None,
'label': 'floor',
'mask': <PIL.Image.Image image mode=L size=640x427 at 0x7FD5B2062B50>},
{'score': None,
'label': 'ceiling',
'mask': <PIL.Image.Image image mode=L size=640x427 at 0x7FD5B2062A10>},
{'score': None,
'label': 'bed ',
'mask': <PIL.Image.Image image mode=L size=640x427 at 0x7FD5B2062E90>},
{'score': None,
'label': 'windowpane',
'mask': <PIL.Image.Image image mode=L size=640x427 at 0x7FD5B2062390>},
{'score': None,
'label': 'cabinet',
'mask': <PIL.Image.Image image mode=L size=640x427 at 0x7FD5B2062550>},
{'score': None,
'label': 'chair',
'mask': <PIL.Image.Image image mode=L size=640x427 at 0x7FD5B2062D90>},
{'score': None,
'label': 'armchair',
'mask': <PIL.Image.Image image mode=L size=640x427 at 0x7FD5B2062E10>}]
```
必要に応じて、`pipeline` の結果を手動で複製することもできます。画像プロセッサで画像を処理し、`pixel_values`を GPU に配置します。
```py
>>> device = torch.device("cuda" if torch.cuda.is_available() else "cpu") # use GPU if available, otherwise use a CPU
>>> encoding = image_processor(image, return_tensors="pt")
>>> pixel_values = encoding.pixel_values.to(device)
```
入力をモデルに渡し、「logits」を返します。
```py
>>> outputs = model(pixel_values=pixel_values)
>>> logits = outputs.logits.cpu()
```
次に、ロジットを元の画像サイズに再スケールします。
```py
>>> upsampled_logits = nn.functional.interpolate(
... logits,
... size=image.size[::-1],
... mode="bilinear",
... align_corners=False,
... )
>>> pred_seg = upsampled_logits.argmax(dim=1)[0]
```
</pt>
</frameworkcontent>
<frameworkcontent>
<tf>
画像プロセッサをロードして画像を前処理し、入力を TensorFlow テンソルとして返します。
```py
>>> from transformers import AutoImageProcessor
>>> image_processor = AutoImageProcessor.from_pretrained("MariaK/scene_segmentation")
>>> inputs = image_processor(image, return_tensors="tf")
```
入力をモデルに渡し、`logits`を返します。
```py
>>> from transformers import TFAutoModelForSemanticSegmentation
>>> model = TFAutoModelForSemanticSegmentation.from_pretrained("MariaK/scene_segmentation")
>>> logits = model(**inputs).logits
```
次に、ロジットを元の画像サイズに再スケールし、クラス次元に argmax を適用します。
```py
>>> logits = tf.transpose(logits, [0, 2, 3, 1])
>>> upsampled_logits = tf.image.resize(
... logits,
... # We reverse the shape of `image` because `image.size` returns width and height.
... image.size[::-1],
... )
>>> pred_seg = tf.math.argmax(upsampled_logits, axis=-1)[0]
```
</tf>
</frameworkcontent>
結果を視覚化するには、[データセット カラー パレット](https://github.com/tensorflow/models/blob/3f1ca33afe3c1631b733ea7e40c294273b9e406d/research/deeplab/utils/get_dataset_colormap.py#L51) を、それぞれをマップする `ade_palette()` としてロードします。クラスを RGB 値に変換します。次に、画像と予測されたセグメンテーション マップを組み合わせてプロットできます。
```py
>>> import matplotlib.pyplot as plt
>>> import numpy as np
>>> color_seg = np.zeros((pred_seg.shape[0], pred_seg.shape[1], 3), dtype=np.uint8)
>>> palette = np.array(ade_palette())
>>> for label, color in enumerate(palette):
... color_seg[pred_seg == label, :] = color
>>> color_seg = color_seg[..., ::-1] # convert to BGR
>>> img = np.array(image) * 0.5 + color_seg * 0.5 # plot the image with the segmentation map
>>> img = img.astype(np.uint8)
>>> plt.figure(figsize=(15, 10))
>>> plt.imshow(img)
>>> plt.show()
```

事前訓練済みモデルをテキスト分類に使用するには、ベースのBERTモデルの上にシーケンス分類ヘッドを追加します。シーケンス分類ヘッドは最終的な隠れた状態を受け入れ、それらをロジットに変換するための線形層です。クロスエントロピー損失は、ロジットとターゲット間で最も可能性の高いラベルを見つけるために計算されます。
テキスト分類を試してみる準備はできましたかDistilBERTを微調整し、推論に使用する方法を学ぶために、完全な[テキスト分類ガイド(英語版)](../en/tasks/sequence_classification)をチェックしてみてください!
