I'm studying for a paper on machine learning, but my computer can't run the code and keeps getting errors. This code runs on a GPU, and I asked my instructor and he said it's not inplace operation. He says it could be a mismatch between python, cuda, and pytorch versions, or a difference in python's torch.cuda.float command.I don't know what difference in python's torch.cuda.float command mean. I have been puzzled by this question for a long time, I hope you can help me, thank you very much!

my python vision is 3.10.13,and torch 1.13.1,cuda 11.7
