Shortcuts

#  torch.hub  ¶

Pytorch Hub is a pre-trained model repository designed to facilitate research
reproducibility.

##  Publishing models  ¶

Pytorch Hub supports publishing pre-trained models(model definitions and pre-
trained weights) to a github repository by adding a simple ` hubconf.py  `
