DINOv2

DINOv2 is a vision foundation model that uses ViT as a feature extractor for multiple downstream tasks like image classification and depth estimation. It focuses on stabilizing and accelerating training through techniques like a faster memory-efficient attention, sequence packing, improved stochastic depth, Fully Sharded Data Parallel (FSDP), and model distillation.

You can find all the original DINOv2 checkpoints under the Dinov2 collection.

Click on the DINOv2 models in the right sidebar for more examples of how to apply DINOv2 to different vision tasks.

The example below demonstrates how to obtain an image embedding with Pipeline or the AutoModel class.

Pipeline
AutoModel

    import torch
    from transformers import pipeline

    pipe = pipeline(
        task="image-classification",
        model="facebook/dinov2-small-imagenet1k-1-layer",
        torch_dtype=torch.float16,
        device=0
    )

    pipe("https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/pipeline-cat-chonk.jpeg")

Quantization reduces the memory burden of large models by representing the weights in a lower precision. Refer to the Quantization overview for more available quantization backends.

The example below uses torchao to only quantize the weights to int4.

    # pip install torchao
    import requests
    from transformers import TorchAoConfig, AutoImageProcessor, AutoModelForImageClassification
    from torchao.quantization import Int4WeightOnlyConfig
    from PIL import Image

    url = 'http://images.cocodataset.org/val2017/000000039769.jpg'
    image = Image.open(requests.get(url, stream=True).raw)

    processor = AutoImageProcessor.from_pretrained('facebook/dinov2-giant-imagenet1k-1-layer')

    quant_config = Int4WeightOnlyConfig(group_size=128)
    quantization_config = TorchAoConfig(quant_type=quant_config)

    model = AutoModelForImageClassification.from_pretrained(
        'facebook/dinov2-giant-imagenet1k-1-layer',
        torch_dtype=torch.bfloat16,
        device_map="auto",
        quantization_config=quantization_config
    )

    inputs = processor(images=image, return_tensors="pt")
    outputs = model(**inputs)
    logits = outputs.logits
    predicted_class_idx = logits.argmax(-1).item()
    print("Predicted class:", model.config.id2label[predicted_class_idx])

##
Notes

- Use torch.jit.trace to speedup inference. However, it will produce some mismatched elements. The difference between the original and traced model is 1e-4.

      import torch
      from transformers import AutoImageProcessor, AutoModel
      from PIL import Image
      import requests

      url = 'http://images.cocodataset.org/val2017/000000039769.jpg'

      processor = AutoImageProcessor.from_pretrained('facebook/dinov2-base')
      model = AutoModel.from_pretrained('facebook/dinov2-base')

      inputs = processor(images=image, return_tensors="pt")
      outputs = model(**inputs)
      last_hidden_states = outputs[0]

      # We have to force return_dict=False for tracing
      model.config.return_dict = False

      with torch.no_grad():
          traced_model = torch.jit.trace(model, [inputs.pixel_values])
          traced_outputs = traced_model(inputs.pixel_values)

This is the configuration class to store the configuration of a Dinov2Model. It is used to instantiate an Dinov2 model according to the specified arguments, defining the model architecture. Instantiating a configuration with the defaults will yield a similar configuration to that of the Dinov2 google/dinov2-base-patch16-224 architecture.

Configuration objects inherit from PretrainedConfig and can be used to control the model outputs. Read the documentation from PretrainedConfig for more information.

Example:

    >>> from transformers import Dinov2Config, Dinov2Model

    >>> # Initializing a Dinov2 dinov2-base-patch16-224 style configuration
    >>> configuration = Dinov2Config()

    >>> # Initializing a model (with random weights) from the dinov2-base-patch16-224 style configuration
    >>> model = Dinov2Model(configuration)

    >>> # Accessing the model configuration
    >>> configuration = model.config

The bare DINOv2 Model transformer outputting raw hidden-states without any specific head on top. This model is a PyTorch torch.nn.Module subclass. Use it as a regular PyTorch Module and refer to the PyTorch documentation for all matter related to general usage and behavior.

Parameters

- pixel_values (`torch.FloatTensor` of shape `(batch_size, num_channels, height, width)`) — Pixel values. Pixel values can be obtained using AutoImageProcessor. See BitImageProcessor.preprocess() for details.
- bool_masked_pos (`torch.BoolTensor` of shape `(batch_size, sequence_length)`) — Boolean masked positions. Indicates which patches are masked (1) and which aren’t (0). Only relevant for pre-training.
- head_mask (`torch.FloatTensor` of shape `(num_heads,)` or `(num_layers, num_heads)`, optional) — Mask to nullify selected heads of the self-attention modules. Mask values selected in `[0, 1]`:
  - 1 indicates the head is not masked,
  - 0 indicates the head is masked.
- output_attentions (`bool`, optional) — Whether or not to return the attentions tensors of all attention layers. See `attentions` under returned tensors for more detail.
- output_hidden_states (`bool`, optional) — Whether or not to return the hidden states of all layers. See `hidden_states` under returned tensors for more detail.
- return_dict (`bool`, optional) — Whether or not to return a ModelOutput instead of a plain tuple.

Returns

transformers.modeling_outputs.BaseModelOutputWithPooling or `tuple(torch.FloatTensor)`

A transformers.modeling_outputs.BaseModelOutputWithPooling or a tuple of `torch.FloatTensor` (if `return_dict=False` is passed or when `config.return_dict=False`) comprising various elements depending on the configuration (Dinov2Config) and inputs.

- pooler_output (`torch.FloatTensor` of shape `(batch_size, hidden_size)`) — Last layer hidden-state of the first token of the sequence (classification token) after further processing through the layers used for the auxiliary pretraining task. E.g. for BERT-family of models, this returns the classification token after processing through a linear layer and a tanh activation function. The linear layer weights are trained from the next sentence prediction (classification) objective during pretraining.

- hidden_states (`tuple(torch.FloatTensor)`, optional, returned when `output_hidden_states=True` is passed or when `config.output_hidden_states=True`) — Tuple of `torch.FloatTensor` (one for the output of the embeddings, if the model has an embedding layer, + one for the output of each layer) of shape `(batch_size, sequence_length, hidden_size)`.

The Dinov2Model forward method, overrides the `__call__` special method.

Although the recipe for forward pass needs to be defined within this function, one should call the `Module` instance afterwards instead of this since the former takes care of running the pre and post processing steps while the latter silently ignores them.

Example:

    >>> from transformers import AutoImageProcessor, Dinov2Model
    >>> import torch
    >>> from datasets import load_dataset

    >>> dataset = load_dataset("huggingface/cats-image", trust_remote_code=True)

    ...     outputs = model(**inputs)
