## Model Usage
|
27 |
+
### Image Classification
|
28 |
+
```python
|
29 |
+
from urllib.request import urlopen
|
30 |
+
from PIL import Image
|
31 |
+
import timm
|
32 |
+
|
33 |
+
img = Image.open(urlopen(
|
34 |
+
'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png'
|
35 |
+
))
|
36 |
+
|
37 |
+
model = timm.create_model('twins_svt_small.in1k', pretrained=True)
|
38 |
+
model = model.eval()
|
39 |
+
|
40 |
+
# get model specific transforms (normalization, resize)
|
41 |
+
data_config = timm.data.resolve_model_data_config(model)
|
42 |
+
transforms = timm.data.create_transform(**data_config, is_training=False)
|
43 |
+
|
44 |
+
output = model(transforms(img).unsqueeze(0)) # unsqueeze single image into batch of 1
|
45 |
+
|
46 |
+
top5_probabilities, top5_class_indices = torch.topk(output.softmax(dim=1) * 100, k=5)
|
47 |
+
```
|
48 |
+
|
49 |
+
### Image Embeddings
|
50 |
+
```python
|
51 |
+
from urllib.request import urlopen
|
52 |
+
from PIL import Image
|
53 |
+
import timm
|
54 |
+
|
55 |
+
img = Image.open(urlopen(
|
56 |
+
'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png'
|
57 |
+
))
|
58 |
+
|
59 |
+
model = timm.create_model(
|
60 |
+
'twins_svt_small.in1k',
|
61 |
+
pretrained=True,
|
62 |
+
num_classes=0, # remove classifier nn.Linear
|
63 |
+
)
|
64 |
+
model = model.eval()
|
65 |
+
|
66 |
+
# get model specific transforms (normalization, resize)
|
67 |
+
data_config = timm.data.resolve_model_data_config(model)
|
68 |
+
transforms = timm.data.create_transform(**data_config, is_training=False)
|
69 |
+
|
70 |
+
output = model(transforms(img).unsqueeze(0)) # output is (batch_size, num_features) shaped tensor
|
71 |
+
|
72 |
+
# or equivalently (without needing to set num_classes=0)
|
73 |
+
|
74 |
+
output = model.forward_features(transforms(img).unsqueeze(0))
|
75 |
+
# output is unpooled, a (1, 49, 512) shaped tensor
|
76 |
+
|
77 |
+
output = model.forward_head(output, pre_logits=True)
|
78 |
+
# output is a (1, num_features) shaped tensor
|
79 |
+
```
