I am working on a chatbot project in which I am working with lookup tables for entity extraction. I am facing this issue while training the model. “ModuleNotFoundError: Cannot find class ‘RegexEntityExtractor’ from global namespace. Please check that there is no typo in the class name and that you have imported the class into the global namespace.” I am using rasa 1.10. Any idea on how to deal with this issue?
