Compiles diffq's diffq.bitpack Cython extension (plain bit-packing, no torch/CUDA headers at build time). Upstream publishes no riscv64 wheel.

Mirrors upstream's .github/workflows/build.yml cibuildwheel step.

Differs from upstream

  • Resolves Cython/numpy/torch from our registry - none have riscv64 wheels on public PyPI.

Testing

  • Deselects test_torchscript_export - needs torchvision, which we don't carry.
  • Rebuilds diffq/ from the installed wheel before testing - diffq/tests sits inside the package and would otherwise shadow it.

License: Wheel ships upstream's own LICENSE (Creative Commons Attribution-NonCommercial 4.0 International); nothing else is vendored.

Built on cp312 (x86_64 rehearsal, against a real torch install); 29 passed, 1 deselected.
