## Model Usage
### Image Classification
```python
from urllib.request import urlopen
from PIL import Image
import torch.nn as nn
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/densenet161.tiatoolbox-pcam",
pretrained=True,
).eval()
# disable norm5's activation, as per torchvision's implementation
model.features.norm5.act == nn.Identity()
# 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)
data = transforms(img).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
```
### Image Embeddings
```python
from urllib.request import urlopen
from PIL import Image
import torch.nn as nn
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/densenet161.tiatoolbox-pcam",
pretrained=True,
num_classes=0,
).eval()
# disable norm5's activation, as per torchvision's implementation
model.features.norm5.act == nn.Identity()
# 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)
data = transforms(img).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
