Read more in the User Guide. get_scorer_names can be used to retrieve the names of all available scorers.

Parameters
scoringstr or callable

Notes

When passed a string, this function always returns a copy of the scorer object. Calling get_scorer twice for the same scorer results in two separate scorer objects.
