## Model Usage

### Image Embeddings

```python
from torchvision.transforms import v2
from PIL import Image
import requests
import torch
import timm
import io

# get example histology image
url = "https://encrypted-tbn0.gstatic.com/images?q=tbn:ANd9GcQc7_xZpGOfQT7sxKwf2w5lL4GAq6IX_CbTzP1NGeenzA&s"
image = Image.open(io.BytesIO(requests.get(url).content))

# load model from the hub
model = timm.create_model(
  model_name="hf-hub:1aurent/vit_small_patch16_224.kaiko_ai_towards_large_pathology_fms",
  dynamic_img_size=True,
  pretrained=True,
).eval()

# get image transform
preprocessing = v2.Compose(
  [
    v2.ToImage(),
    v2.Resize(size=224),
    v2.CenterCrop(size=224),
    v2.ToDtype(torch.float32, scale=True),
    v2.Normalize(
      mean=(0.5, 0.5, 0.5),
      std=(0.5, 0.5, 0.5),
    ),
  ]
)

data = preprocessing(image).unsqueeze(0) # input is a (batch_size, num_channels, img_size, img_size) shaped tensor
output = model(data)  # output is a (batch_size, num_features) shaped tensor
```
