this bug caused by wrong version of libnccl
i solved it by reinstalling a right ver libnccl and recreating a new python env based on this libnccl

Hi, I am running into the same issue when building from source. I don't understand how libnccl version affects the filenotfound error? Any other solution to this?

the mirror url is write in some workplace file. it seems the file not found problem not the error reason. the incorrect libnccl version is the main cause.
