Trying to unpickle estimator DecisionTreeClassifier from version 0.24.2 when using version 1.0.1. This might lead to breaking code or invalid results. Use at your own risk.

Looks like another issue caused by using scikit 1.0.1 instead of 24.2.

Or you can train again AutoML with newer version of scikit-learn. That might be better solution fo the future.
