## Model Usage |
|
### Image Classification |
|
```python |
|
from urllib.request import urlopen |
|
from PIL import Image |
|
import timm |
|
|
|
img = Image.open(urlopen( |
|
'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png' |
|
)) |
|
|
|
model = timm.create_model('convnext_nano.in12k', pretrained=True) |
|
model = model.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)) # unsqueeze single image into batch of 1 |
|
|
|
top5_probabilities, top5_class_indices = torch.topk(output.softmax(dim=1) * 100, k=5) |
|
``` |
|
|
|
### Feature Map Extraction |
|
```python |
|
from urllib.request import urlopen |
|
from PIL import Image |
|
import timm |
|
|
|
img = Image.open(urlopen( |
|
'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png' |
|
)) |
|
|
|
model = timm.create_model( |
|
'convnext_nano.in12k', |
|
pretrained=True, |
|
features_only=True, |
|
) |
|
model = model.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)) # unsqueeze single image into batch of 1 |
|
|
|
for o in output: |
|
# print shape of each feature map in output |
|
# e.g.: |
|
# torch.Size([1, 80, 56, 56]) |
|
# torch.Size([1, 160, 28, 28]) |
|
# torch.Size([1, 320, 14, 14]) |
|
# torch.Size([1, 640, 7, 7]) |
|
|
|
print(o.shape) |
|
``` |
|
|
|
### Image Embeddings |
|
```python |
|
from urllib.request import urlopen |
|
from PIL import Image |
|
import timm |
|
|
|
img = Image.open(urlopen( |
|
'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png' |
|
)) |
|
|
|
model = timm.create_model( |
|
'convnext_nano.in12k', |
|
pretrained=True, |
|
num_classes=0, # remove classifier nn.Linear |
|
) |
|
model = model.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 |
|
|
|
# or equivalently (without needing to set num_classes=0) |
|
|
|
output = model.forward_features(transforms(img).unsqueeze(0)) |
|
# output is unpooled, a (1, 640, 7, 7) shaped tensor |
|
|
|
output = model.forward_head(output, pre_logits=True) |
|
# output is a (1, num_features) shaped tensor |
|
``` |
