## pytorch series 3 – dynamic calculation graph and automatic differentiation

This article is interpreted based on pytorch1.10:torch – PyTorch 1.10 documentation Text operations are available on github at Shirley-Xie/pytorch_exercise · GitHub, and there are running results. 1. Dynamic calculation graph Problems solved: Because deep learning increases the types and numbers of various tensor operations, it will lead to various unexpected problems, such as whether multiple […]

## Understand the pytorch hook mechanism in one article

Pytorch’s hook mechanism allows us to debug backward, view forward activations, and modify gradients without modifying the model class. A hook is a function that can be executed during forward and backward calculations. In pytorch, you can add hooks to Tensor and nn.Module. There are two types of hooks, forward hook and backward hook. 1. […]
