Thanks a lot for the PR @jamesmuking5 .

The changes LGTM but I would suggest to just replace with torch.amp.autocast("cuda", ...) since none of those are expected to be on CPU.

If you can, it'd be great to also address the rest of the occurrences or torch.cuda.amp.* (I could find the ones below), but I can do that in a follow-up PR if you prefer. Thanks!
