Hi, I think the reason is probably due to the update of torch and pytorch lightning.
The code is implemented using torch 1.7.1 and pytorch lightning 1.5.9 --> but now they both have 2.x as latest version.
Perhaps you can check if the declaration and assignment of the Lambda scheduler needs to be changed.

是pytorch版本问题，你试试torch==1.10.0
