| # Workflow to build and test wheels for the free-threaded Python build. | |
| # | |
| # This should be merged back into wheels.yml when free-threaded wheel | |
| # builds can be uploaded to pypi along with the rest of scipy's release | |
| # artifacts. | |
| # | |
| # To work on the wheel building infrastructure on a fork, comment out: | |
| # | |
| # if: github.repository == 'scipy/scipy' | |
| # | |
| # in the get_commit_message job. Be sure to include [wheel build] in your commit | |
| # message to trigger the build. All files related to wheel building are located | |
| # at tools/wheels/ | |
