scikit-learn

The reference Python machine-learning library (66K+★), incubated at Inria and stewarded through the scikit-learn Consortium at the Inria Foundation, now spun into the :probabl. company. The single most-adopted piece of ML infrastructure in the world, alongside the Inria-rooted joblib (parallelism), skrub (tabular prep, ex-dirty_cat), and MNE-Python (MEG/EEG). Dated mid-window; development is continuous.
