Here: self.estimator = self.estimator.best_estimator_. you are taking the best-estimator (MLPClassifier) and store it into variable self.estimator, overwriting your original variable self.estimator. But then: self.estimator.best_estimator_. is wrong, as self.estimator is already the best estimator, but it has no attribute named like that.
