Compiles a small Cython extension implementing the dynamic-programming monotonic alignment search used by Glow-TTS/VITS-style TTS models. Upstream publishes no riscv64 wheel.

Mirrors upstream's build-wheels job, which is plain pypa/cibuildwheel with build = "cp*" from [tool.cibuildwheel].

Differs from upstream

  • musllinux dropped - torch, the test-only cpu extra, has no riscv64 musllinux wheel on our registry.

Matrix: cp312/cp313/cp314/cp314t (upstream also builds cp310/cp311, not in this repo's default floor).

Testing

  • same as upstream

License: OK

Builds cleanly from a local pip wheel on x86_64 with no patches; the Cython extension (plain prange-parallel loop, no SIMD intrinsics) has no architecture-specific code.

…n one CIBW_ENVIRONMENT

CIBW_ENVIRONMENT_LINUX replaces CIBW_ENVIRONMENT instead of merging into
it, so PIP_EXTRA_INDEX_URL never reached the build container and the
numpy>=2.0.0 build requirement could not be resolved for riscv64.
