Summary

Inception v3 is a convolutional neural network architecture from the Inception family that makes several improvements including using Label Smoothing, Factorized 7 x 7 convolutions, and the use of an auxiliary classifer to propagate label information lower down the network (along with the use of batch normalization for layers in the sidehead). The key building block is an Inception Module.

How do I load this model?

To load a pretrained model:

import torchvision.models as models
inception_v3 = models.inception_v3(pretrained=True)

Replace the model name with the variant you want to use, e.g. inception_v3. You can find the IDs in the model summaries at the top of this page.

How do I train this model?

You can follow the torchvision recipe on GitHub for training a new model afresh.
