Stop building for CUDA toolkit < 11.8 by matthewdouglas · Pull Request #1605 · bitsandbytes-foundation/bitsandbytes

#1544 set the new PyTorch minimum version of 2.2.0. We wish to align with the standard PyTorch distribution, which ships with CUDA 11.8 builds as the minimum by default from 2.1.

This change helps reduce maintenance burden in addition to keeping our binary sizes in check.

Building from source with older versions of the CUDA toolkit is still feasible, but will no longer be officially supported.
