--- BEGIN ISSUE ---
Do we support GPU distributed training?
Hi, thanks for the awesome project!

Does the code base support distributed training? If not, is it possible to support it after some code modifications?

By the way, what is the way to set batch size and gpu number if I want to use GPU to train the model?

Thank you for your kind attention.
