+If an overridden ``shell`` command includes paths that cannot be imported,
+these errors are shown when ``verbosity`` is set to ``1`` or higher.

+Note that automatic imports can be disabled for a specific ``shell`` session
+using the :option:`--no-imports <shell --no-imports>` flag. To permanently
+disable automatic imports, override ``get_auto_imports()`` to return ``None``::
