Not off-hand because it's been a while, but IIRC the names of some methods were changed, arguments were added/removed. I will say that was before version 1.0, so it may be more stable now.

Last I saw the nvidia driver situation did not improve though. I wanted to come back to some old code, installed a new version of PyTorch. It complained that my GPU drivers were not recent enough, had to do this long tedious process that took over an hour to get newer drivers working.
