Nvlink error ( installing from source )

I am trying to install pytorch from source. However, I come across an nvlink error. I was wondering whether it’s due to my inappropriate environment or something else like the carelessness of your development.

Could anyone help me with this nvlink error?

you can try to turn-off NCCL support in CmakeLists.txt.

Oh, exciting! I solved it! Thank you for your help!

Hello, I still have problems with the installation. If I turn-off NCCL, I won’t be able to use multi-GPU, will I?

And I have NVCC error:

Could anyone help me with that?
