can i use cuda if i disable NCCL?


Yes, as NCCL is used for distributed workloads.

how to check PyTorch source min compute capability?


An easy way would be to try to build it for the specified architecture and see if the source code uses functions from a later compute capability. Another way would be to check for known functions introduced for specific architectures.



 jaypatel:

should i be using older torch version to build because have read threads here some are able to build with v1.6.0(using git checkout) have had tried some older versions too but getting same error.


You could try that, as I don’t know which version supported 3.0. The current binaries ship with 3.7 to 8.6.
