## Model Usage
|
28 |
+
### Image Classification
|
29 |
+
```python
|
30 |
+
from urllib.request import urlopen
|
31 |
+
from PIL import Image
|
32 |
+
import timm
|
33 |
+
|
34 |
+
img = Image.open(urlopen(
|
35 |
+
'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png'
|
36 |
+
))
|
37 |
+
|
38 |
+
model = timm.create_model('tf_efficientnetv2_s.in1k', pretrained=True)
|
39 |
+
model = model.eval()
|
40 |
+
|
41 |
+
# get model specific transforms (normalization, resize)
|
42 |
+
data_config = timm.data.resolve_model_data_config(model)
|
43 |
+
transforms = timm.data.create_transform(**data_config, is_training=False)
|
44 |
+
|
45 |
+
output = model(transforms(img).unsqueeze(0)) # unsqueeze single image into batch of 1
|
46 |
+
|
47 |
+
top5_probabilities, top5_class_indices = torch.topk(output.softmax(dim=1) * 100, k=5)
|
48 |
+
```
|
49 |
+
|
50 |
+
### Feature Map Extraction

|
70 |
+
|
71 |
+
output = model(transforms(img).unsqueeze(0)) # unsqueeze single image into batch of 1
|
72 |
+
|
73 |
+
for o in output:
|
74 |
+
# print shape of each feature map in output
|
75 |
+
# e.g.:
|
76 |
+
# torch.Size([1, 24, 150, 150])
|
77 |
+
# torch.Size([1, 48, 75, 75])
|
78 |
+
# torch.Size([1, 64, 38, 38])
|
79 |
+
# torch.Size([1, 160, 19, 19])
|
80 |
