INSTALL.md Problem - Githubissues

Hello, I failed to follow the mega.pytorch.INSTALL.md due to the CUDA version being incompatible with the Pytorch version. I exactly followed the INSTALL.md step by step, and I did install pytorch=1.3.0 and cudatoolkit=10.0 successfully. But, when I tried to install apex, some errors just popped up. Below is the error message.

` torch.version = 1.3.0

I followed this link and the answer is to comment this check. I also followed this answer, but another even weird error message was poped up.

supported".format(arch)) ValueError: Unknown CUDA arch (8.6) or GPU not supported

BTW, the GPU I am currently using is 3090. I am not too sure if 3090 can support the CUDA version which is less than 11. The cuda drive I am installing is 455.45.01.

May I please ask you if there are any other ways to sort out my problems??

Thank you so much for your help. Looking forward to your response soon! Cheers! :-)
