Hello, will the gradient of loss be calculated when ffl is used as loss? I try to put ffl on cuda, but it is always a scalar, and mse is a tensor with calculated gradient. Here are my changes:

The following are the values of mse and ffl, their forms are different, I don’t know if I’m wrong here.

Sorry to bother you again. I read the source code and it seems that this is indeed a scalar. I would like to ask why a frequency loss is calculated for the entire batch. If it is modified to calculate a frequency loss for each generated image and the original image, is it reasonable?
