Hello @duanzhihua the one you trying to run is developed in 2.X and you are running the boto on 3.X, make the necessary changes in the code as per the latest rasa, you are good to go.

Thank you for your guidance. I ran the data migration command according to the official website documents. The problem has been solved. Thank you
