Model Description

Model inception_v3 is from the Rethinking the Inception Architecture for Computer Vision paper

The 1-crop error rates on the imagenet dataset with the pretrained model are listed below.

Model structure	Top-1 error	Top-5 error
inception_v3	22.55	6.44

Notes on Inputs

All pre-trained models expect input images normalized in the same way, i.e. mini-batches of 3-channel RGB images of shape (3 x H x W), where H and W are expected to be at least 224. The images have to be loaded in to a range of [0, 1] and then normalized using mean = [0.485, 0.456, 0.406] and std = [0.229, 0.224, 0.225]. You can use the following transform to normalize:

normalize = transforms.Normalize(mean=[0.485, 0.456, 0.406],
                                 std=[0.229, 0.224, 0.225])

Example:

import torch
model = torch.hub.load('pytorch/vision', 'inception_v3', pretrained=True)
