Please fix python-scikit-learn at your earliest convenience and set the bug's status to
ASSIGNED when you start fixing it. If the bug remains in NEW state for 8 weeks,
python-scikit-learn will be orphaned. Before branching of Fedora 46,
python-scikit-learn will be retired, if it still fails to build.

In https://bodhi.fedoraproject.org/updates/FEDORA-2026-2551d0d66b we have shipped Python 3.15.0b4.

All packages that link to libpython or have extension modules should be rebuilt, or they will segfault on import/usage.

Packages using stable ABI might not need a rebuild.

This package was not rebuilt because we were unable to do so.
Please rebuild it with Python 3.15.0b4+ ASAP. Thanks
