Could you please provide some comments on what this line does? Skimming the pipeline, this follows a CUDA build, I don't see any potential variant here since there's no CPU build and NCCL is still installed.

This is an initial stage, where we build a single variant for the CUDA build. In the future, I plan to build the CPU variant and other variants.

WheelNext is a proposal to improve Python wheels to better support specialized hardware and reduce the size of individual wheels. In particular, we are keen to adopt the Wheel Variant proposal. Also see the presentation.
Use the prototype in https://github.com/wheelnext/pep_xxx_wheel_variants to build a variant wheel. A variant wheel is just like a regular wheel, but with extra variant metadata like
nvidia :: cuda :: 12.
