For auto-propagated callbacks, this method is called only once, before running the fit method of the outermost estimator. Parameters ---------- estimator : estimator instance The estimator calling this callback hook. context : `sklearn.callback.CallbackContext` instance Context of the corresponding task. This is usually the root context of the estimator but it can be an intermediate context if the estimator is a sub-estimator of a meta-estimator.
