https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: sci-libs/scikit-learn-1.1.2 fails to compile (PYTHON-3.12-SYSTEM). Discovered on: amd64 (internal ref: python-3.12_tinderbox) NOTE: (PYTHON-3.12-SYSTEM) in the summary means that the bug was found on a machine that runs python-3.12 but this bug MAY or MAY NOT BE related to the new python version

I inquired, and apparently ≥scikit-learn-1.2 supports ≥cython-3. However, it seems that recent versions went back to requiring <cython-3 for performance reasons (see https://github.com/scikit-learn/scikit-learn/issues/26858).
jeremiedbb commented on Oct 4 Good news, I ran some benchmarks regarding the estimators for which we identified slowdowns coming from cython 3 (RandomForest*, (Hist)GradientBoosting*, KNeighbors*) against the latest cython master and they're all as fast as they were with cython 0.29.36 (sometimes even a little bit faster) ! https://github.com/scikit-learn/scikit-learn/issues/27086#issuecomment-1747111276 scikit-learn-1.3.2 running fine here - no performance issues with cython-3.0.5
(In reply to je_fro@yahoo.com from comment #5) > scikit-learn-1.3.2 running fine here - no performance issues with > cython-3.0.5 So this bug should depend on 910258.
