# DINOv2
|
|
|
|
[DINOv2](https://huggingface.co/papers/2304.07193) is a vision foundation model that uses [ViT](./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](https://huggingface.co/collections/facebook/dinov2-6526c98554b3d2576e071ce3) collection.
|
|
|
|
> [!TIP]
|
|
> 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.

<hfoption id="Pipeline">
|
|
|
|
```py
|
|
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")
|

```
|
|

</hfoption>
|
|
<hfoption id="AutoModel">
|
|
|
|
```py
|
|
import requests
|
|
from transformers import AutoImageProcessor, AutoModelForImageClassification
|
|
from PIL import Image
|
|
|
|
url = "http://images.cocodataset.org/val2017/000000039769.jpg"
|
|
image = Image.open(requests.get(url, stream=True).raw)

|
|
predicted_class_idx = logits.argmax(-1).item()
|

```

|
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.
|
|
|
|
```py
|
|
# 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](https://pytorch.org/docs/stable/generated/torch.jit.trace.html) to speedup inference. However, it will produce some mismatched elements. The difference between the original and traced model is 1e-4.
|
|
|
|
```py
|
|
import torch
|
|
from transformers import AutoImageProcessor, AutoModel
|
|
from PIL import Image
|
|
import requests
|
|
|
|
url = 'http://images.cocodataset.org/val2017/000000039769.jpg'
|
|
image = Image.open(requests.get(url, stream=True).raw)
|
|
|
|
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)
|
|
|
|
print((last_hidden_states - traced_outputs[0]).abs().max())
|
|
```
