# `sklearn.utils.discovery`.all_estimators

sklearn.utils.discovery.all_estimators(type_filter=None)

  Get a list of all estimators from `sklearn`.

  This function crawls the module and gets all classes that inherit from BaseEstimator. Classes that are defined in test-modules are not included.

  Parameters:
    type_filter{“classifier”, “regressor”, “cluster”, “transformer”} or list of such str, default=None

      Which kind of estimators should be returned. If None, no filter is applied and all estimators are returned. Possible values are ‘classifier’, ‘regressor’, ‘cluster’ and ‘transformer’ to get estimators only of these specific types, or a list of these to get the estimators that fit at least one of the types.

  Returns:
    estimators list of tuples

      List of (name, class), where `name` is the class name as string and `class` is the actual type of the class.
