+ ## Model Usage
29
+ ### Image Classification
30
+ ```python
31
+ from urllib.request import urlopen
32
+ from PIL import Image
33
+ import timm
34
+
35
+ img = Image.open(urlopen(
36
+ 'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png'
37
+ ))
38
+
39
+ model = timm.create_model('mobilevit_s.cvnets_in1k', pretrained=True)
40
+ model = model.eval()
41
+
42
+ # get model specific transforms (normalization, resize)
43
+ data_config = timm.data.resolve_model_data_config(model)
44
+ transforms = timm.data.create_transform(**data_config, is_training=False)
45
+
46
+ output = model(transforms(img).unsqueeze(0)) # unsqueeze single image into batch of 1
47
+
48
+ top5_probabilities, top5_class_indices = torch.topk(output.softmax(dim=1) * 100, k=5)
49
+ ```
50
+
51
+ ### Feature Map Extraction
52
+ ```python
53
+ from urllib.request import urlopen
54
+ from PIL import Image
55
+ import timm
56
+
57
+ img = Image.open(urlopen(
58
+ 'https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/beignets-task-guide.png'
59
+ ))
60
+
61
+ model = timm.create_model(
62
+ 'mobilevit_s.cvnets_in1k',
63
+ pretrained=True,
64
+ features_only=True,
65
+ )
66
+ model = model.eval()
67
+
68
+ # get model specific transforms (normalization, resize)
69
+ data_config = timm.data.resolve_model_data_config(model)
70
+ transforms = timm.data.create_transform(**data_config, is_training=False)
71
+
72
+ output = model(transforms(img).unsqueeze(0)) # unsqueeze single image into batch of 1
73
+
74
+ for o in output:
75
+ # print shape of each feature map in output
76
+ # e.g.:
77
+ # torch.Size([1, 32, 128, 128])
78
+ # torch.Size([1, 64, 64, 64])
79
+ # torch.Size([1, 96, 32, 32])
80
+ # torch.Size([1, 128, 16, 16])
81
+ # torch.Size([1, 640, 8, 8])
82
+
83
+ print(o.shape)
84
+ ```
85
+
86
+ ### Image Embeddings
87
+ ```python
88

90
+ import timm
91
+
92
+ img = Image.open(urlopen(

99
+ num_classes=0, # remove classifier nn.Linear
100
+ )
101
+ model = model.eval()
102
+
103
+ # get model specific transforms (normalization, resize)
104
+ data_config = timm.data.resolve_model_data_config(model)
105
+ transforms = timm.data.create_transform(**data_config, is_training=False)
106
+
107
+ output = model(transforms(img).unsqueeze(0)) # output is (batch_size, num_features) shaped tensor
108
+
109
+ # or equivalently (without needing to set num_classes=0)
110
+
111
+ output = model.forward_features(transforms(img).unsqueeze(0))
112
+ # output is unpooled, a (1, 640, 8, 8) shaped tensor
113
+
114
+ output = model.forward_head(output, pre_logits=True)
115
+ # output is a (1, num_features) shaped tensor
