Unfortunately I think we might need a cython release that builds numpy under free-threaded python. At least if we want to avoid hacks like the change I made to I don't think there's any other way to customize the build requirements? Could I maybe do a sed replacement in pyproject.toml on the build image in the |

Looks like the wheels successfully built for manylinux and musllinux: https://github.com/numpy/numpy/actions/runs/9215227199 |

This is indeed not mergeable with the change to pyproject.toml. In addition, we may not want to have the cp313t builds in wheel.yml, because I don't think we want to upload them to PyPI for 2.1.0. So how about this:
- copy
wheels.ymlwith these changes tofree_threaded.yml - edit that file so it only contains what is needed for free-threaded builds (no sdist, no other platforms, no upload to the
STAGINGbucket) - set the
PIP_NO_BUILD_ISOLATION=1env var - then build Cython from latest master (no change to
pyproject.tomlneeded anymore, because of turning off build isolation)
Then we can merge this and start uploading to https://anaconda.org/scientific-python-nightly-wheels/numpy

I ended up doing this in a slightly different way because setting The tests pass on both manylinux and musllinux with the GIL disabled - I think the wheels should be ready to upload along with the nightlies. |

Note for anyone curious: I'm leaving the windows and mac-specific stuff in here even though it's unused because our intention is to add mac builds and then windows builds when that's possible.

I think all that's needed is this one-line change and the 3.13 wheel builder will automatically create a free-threaded wheel. Let's see...
