Enables Successive Halving search-estimators
The API and results of these estimators might change without any deprecation cycle.
>>> # explicitly require this experimental feature >>> from sklearn.experimental import enable_halving_search_cv # noqa >>> # now you can import normally from model_selection >>> from sklearn.model_selection import HalvingRandomSearchCV >>> from sklearn.model_selection import HalvingGridSearchCV
# noqa comment comment can be removed: it just tells linters like
flake8 to ignore the import, which appears as unused.
