sklearn.base.clone(estimator, *, safe=True)[source]

Constructs a new estimator with the same parameters.

Clone does a deep copy of the model in an estimator without actually copying attached data. It yields a new estimator with the same parameters that has not been fit on any data.

estimator{list, tuple, set} of estimator objects or estimator object

The estimator or group of estimators to be cloned.

safebool, default=True

If safe is false, clone will fall back to a deep copy on objects that are not estimators.
