Rasa Falling Back

I am beginner to the Rasa. When I excuting a code, it automatically falling back. Can any one help me to out of it?

Hi @alludaddy. That highly depends on how your assistant is implemented right now - how much training data you have, how does it looks like. Would you be able to share some of the files here? nlu.yml, domain.yml would be the most useful files to look into.
