    importerror: cannotimportname 'safe_indexing' from

    Hi @Paulj1989 and thanks for letting us know!. It looks like scikit-learn has again changed their public/private API, so utils.safe_indexing is now called utils._safe_indexing.In order for the utility to work in Yellowbrick, we will have to change our usage of safe_indexing to support users with versions of scikit-learn >= 0.24 without deprecating support for users with versions of scikit

    yellowbrick.classifier.confusion_matrix — yellowbrick v1.3

    A confusion matrix shows each combination of the true and predicted classes for a test data set. The default color map uses a yellow/orange/red color scale. The user can choose between displaying values as the percent of true (cell value divided by sum of row) or as direct counts
