+ # ReXNet-1.5x model
13
+
14
+ Pretrained on [ImageNette](https://github.com/fastai/imagenette). The ReXNet architecture was introduced in [this paper](https://arxiv.org/pdf/2007.00992.pdf).
15
+
16
+
17
+ ## Model description
18
+
19
+ The core idea of the author is to add a customized Squeeze-Excitation layer in the residual blocks that will prevent channel redundancy.
20
+
21
+
22
+ ## Installation
23
+
24
+ ### Prerequisites
25
+
26
+ Python 3.6 (or higher) and [pip](https://pip.pypa.io/en/stable/)/[conda](https://docs.conda.io/en/latest/miniconda.html) are required to install Holocron.
27
+
28
+ ### Latest stable release
29
+
30
+ You can install the last stable release of the package using [pypi](https://pypi.org/project/pylocron/) as follows:
31
+
32
+ ```shell
33
+ pip install pylocron
34
+ ```
35
+
36
+ or using [conda](https://anaconda.org/frgfm/pylocron):
37
+
38
+ ```shell
39
+ conda install -c frgfm pylocron
40
+ ```
41
+
42
+ ### Developer mode
43
+
44
+ Alternatively, if you wish to use the latest features of the project that haven't made their way to a release yet, you can install the package from source *(install [Git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git) first)*:
45
+
46
+ ```shell
47
+ git clone https://github.com/frgfm/Holocron.git
48
+ pip install -e Holocron/.
49
+ ```
50
+
51
+
52
+ ## Usage instructions
53
+
54
+ ```python
55
+ from PIL import Image
56
+ from torchvision.transforms import Compose, ConvertImageDtype, Normalize, PILToTensor, Resize
57
+ from torchvision.transforms.functional import InterpolationMode
58
+ from holocron.models import model_from_hf_hub
59
+
60
+ model = model_from_hf_hub("frgfm/rexnet1_5x").eval()
61
+
62
+ img = Image.open(path_to_an_image).convert("RGB")
63
+
64
+ # Preprocessing
65
+ config = model.default_cfg
66
+ transform = Compose([
67
+ Resize(config['input_shape'][1:], interpolation=InterpolationMode.BILINEAR),
68
+ PILToTensor(),
69
+ ConvertImageDtype(torch.float32),
70
+ Normalize(config['mean'], config['std'])
71
+ ])
72
+
73
+ input_tensor = transform(img).unsqueeze(0)
74
+
75
+ # Inference
76
+ with torch.inference_mode():
77
+ output = model(input_tensor)
78
+ probs = output.squeeze(0).softmax(dim=0)
