+    The unit test are run against
+    :epkg:`scikit-learn` 0.23, 0.24.
+    Some unit tests are failing with version 0.23.
+    They were disabled instead of looking into a cause
+    which does not appear with the latest version.
+    It affects all classes inheriting from :class:`SkBase
+    <mlinsights.sklapi.sklearn_base.SkBase>` where a model
+    using it is trained. The issue happens in :epkg:`joblib`.
