Hello,

During impact testing of Cython 3.2.0 on Rawhide, python-scikit-learn failed to build.

One reason is due to the upper bound restriction to < 3.2.0. This can be fixed by adjustment to the SPEC file sed for Cython to something like:

sed -i -E 's|Cython>=3\.0\.10(,<[0-9.]+)?|Cython>=3.0.9|' pyproject.toml

However absolute imports are required now with the latest Cython and there are many pull requests upstream that can be quite a hurdle to backport: https://github.com/scikit-learn/scikit-learn/issues/32315

Best way to resolve this would be to either upgrade to a git snapshot or ping upstream for a new release.

Reproducible: Always
