Small addition to @MariosOreo’s answer: if your loss function uses reduction='mean', the loss will be normalized by the sum of the corresponding weights for each element.If you are using reduction='none', you would have to take care of the normalization yourself. That’s a neat solution as well… I ended up changing my loss function again to NLLLoss, which supports class weights, and it’s probably the easiest native solution.
