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 : estimator object, or list, tuple or set of objects

The estimator or group of estimators to be cloned

safe : boolean, optional

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