Package: python3-joblib
Tags: fixed-upstream
Control: affects -1 scikit-learn statsmodels
Control: block 966426 by -1
Severity: serious
Justification: causes other packages to FTBFS
Our current version of joblib is incompatible with Python 3.9, which was
recently added to the supported versions list (#966426). This causes at
least scikit-learn and statsmodels to fail their tests.
Upstream fix: https://github.com/joblib/loky/pull/250
Traceback (from scikit-learn test log):
