No binary build for 2.22.3 for NCCL on PyPi Cuda11 #1408

Open Skylion007 opened 3 months ago

I didn't see any comments about support for CUDA 11.8 being dropped in the changelog. Is this oversight intentional or a release snafu?

^ latest binary is the prior 2.21.5 version

NCCL 2.22.3 was tested with CUDA 12.2, 12.4, and 12.5. You might be able to successfully compile and run it with CUDA 11.8 but, given that we don't test it that way internally anymore, we make no guarantees whether or how well it will work.
