Is that ok not using ‘criterion.cuda()’ before criterion?

Hi,

If I want to summarize, you only need to use `.cuda` on criterion if the criterion function has parameters.

Here is the posts related to this situation: [Move the loss function to GPU](https://discuss.pytorch.org/t/move-the-loss-function-to-gpu/20060) and [Why `criterion.cuda()` is not needed but `model.cuda()` is?](https://discuss.pytorch.org/t/why-criterion-cuda-is-not-needed-but-model-cuda-is/17410/2)

Bests
