## Model Usage |
|
|
|
### Image Embeddings |
|
```python |
|
from urllib.request import urlopen |
|
from PIL import Image |
|
import timm |
|
|
|
# get example histology image |
|
img = Image.open( |
|
urlopen( |
|
"https://github.com/owkin/HistoSSLscaling/raw/main/assets/example.tif" |
|
) |
|
) |
|
|
|
# load model from the hub |
|
model = timm.create_model( |
|
model_name="hf-hub:1aurent/vit_base_patch16_224.owkin_pancancer", |
|
pretrained=True, |
|
).eval() |
|
|
|
# get model specific transforms (normalization, resize) |
|
data_config = timm.data.resolve_model_data_config(model) |
|
transforms = timm.data.create_transform(**data_config, is_training=False) |
|
|
|
output = model(transforms(img).unsqueeze(0)) # output is (batch_size, num_features) shaped tensor |
|
``` |
