Description

sklearn.multiclass.OneVsRestClassifier has an n_jobs parameter, which runs the fit method in parallel for all of the sub-estimators. However, predict or predict_proba are not executed in parallel.

Here is the code that is not parallel for predict_proba, and here is the code that is parallel for fit.
