26
+ ## 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('efficientvit_l2.r224_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
+ ### Feature Map Extraction
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
+ 'efficientvit_l2.r224_in1k',
61
+ pretrained=True,
62
+ features_only=True,
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)) # unsqueeze single image into batch of 1
71
+
72
+ for o in output:
73
+ # print shape of each feature map in output
74
+ # e.g.:
75
+ # torch.Size([1, 64, 56, 56])
76
+ # torch.Size([1, 128, 28, 28])
77
+ # torch.Size([1, 256, 14, 14])
78
+ # torch.Size([1, 512, 7, 7])
79
+
80
+ print(o.shape)
81
+ ```
82
+
83
+ ### Image Embeddings
84
+ ```python
85

86
+ from PIL import Image
87
+ import timm
88
+
89
+ img = Image.open(urlopen(

92

93

95
+ pretrained=True,
96
+ num_classes=0, # remove classifier nn.Linear
97
+ )
98
+ model = model.eval()
99
+
100
+ # get model specific transforms (normalization, resize)
101
+ data_config = timm.data.resolve_model_data_config(model)
102
+ transforms = timm.data.create_transform(**data_config, is_training=False)
103
+
104
+ output = model(transforms(img).unsqueeze(0)) # output is (batch_size, num_features) shaped tensor
105
+
106
+ # or equivalently (without needing to set num_classes=0)
107
+
108
+ output = model.forward_features(transforms(img).unsqueeze(0))
109
+ # output is unpooled, a (1, 512, 7, 7) shaped tensor
110
+
111
+ output = model.forward_head(output, pre_logits=True)
112
+ # output is a (1, num_features) shaped tensor
