## 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('swin_small_patch4_window7_224.ms_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
|
51 |
+
```python
|
52 |
+
from urllib.request import urlopen
|
53 |
+
from PIL import Image
|
54 |
+
import timm
|
55 |
+
|
56 |
+
img = Image.open(urlopen(
|
57 |
+
'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png'
|
58 |
+
))
|
59 |
+
|
60 |
+
model = timm.create_model(
|
61 |
+
'swin_small_patch4_window7_224.ms_in1k',
|
62 |
+
pretrained=True,
|
63 |
+
features_only=True,
|
64 |
+
)
|
65 |
+
model = model.eval()
|
66 |
+
|
67 |
+
# get model specific transforms (normalization, resize)
|
68 |
+
data_config = timm.data.resolve_model_data_config(model)
|
69 |
+
transforms = timm.data.create_transform(**data_config, is_training=False)
|
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. for swin_base_patch4_window7_224 (NHWC output)
|
76 |
+
# torch.Size([1, 56, 56, 128])
|
77 |
+
# torch.Size([1, 28, 28, 256])
|
78 |
+
# torch.Size([1, 14, 14, 512])
|
79 |
+
# torch.Size([1, 7, 7, 1024])
|
80 |
+
# e.g. for swinv2_cr_small_ns_224 (NCHW output)
|
81 |
+
# torch.Size([1, 96, 56, 56])
|
82 |
+
# torch.Size([1, 192, 28, 28])
|
83 |
+
# torch.Size([1, 384, 14, 14])
|
84 |
+
# torch.Size([1, 768, 7, 7])
|
85 |
+
print(o.shape)
|
86 |
+
```
|
87 |
+
|

+
### Image Embeddings
|
89 |
+
```python
|
90 |
+
from urllib.request import urlopen
|
91 |
+
from PIL import Image
|
92 |
+
import timm
|
93 |
+
|
94 |
+
img = Image.open(urlopen(
|
95 |
+
'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png'
|
96 |
+
))
|
97 |
+
|
98 |
+
model = timm.create_model(
|
99 |
+
'swin_small_patch4_window7_224.ms_in1k',
|
100 |
+
pretrained=True,
|
101 |
+
num_classes=0, # remove classifier nn.Linear
|
102 |
+
)
|
103 |
+
model = model.eval()
|
104 |
+
|
105 |
+
# get model specific transforms (normalization, resize)
|
106 |
+
data_config = timm.data.resolve_model_data_config(model)
|
107 |
+
transforms = timm.data.create_transform(**data_config, is_training=False)
|
108 |
+
|
109 |
+
output = model(transforms(img).unsqueeze(0)) # output is (batch_size, num_features) shaped tensor
|
110 |
+
|
111 |
+
# or equivalently (without needing to set num_classes=0)
|
112 |
+
|
113 |
+
output = model.forward_features(transforms(img).unsqueeze(0))
|
114 |
+
# output is unpooled (ie.e a (batch_size, H, W, num_features) tensor for swin / swinv2
|
115 |
+
# or (batch_size, num_features, H, W) for swinv2_cr
|
116 |
+
|
117 |
+
output = model.forward_head(output, pre_logits=True)
|
118 |
+
# output is (batch_size, num_features) tensor
|
119 |
