Core model Domain specification issue

Rasa Open Source
1

I’m facing the below issue while running the app with the command

rasa run --model /home/pavankalyan/PycharmProjects/chatbot-app/ex_models --enable-api --port 8083 --debug --credentials /home/pavankalyan/PycharmProjects/chatbot-app/conf/credentials.yml --endpoints /home/pavankalyan/PycharmProjects/chatbot-app/conf/endpoints.yml --log-file /home/pavankalyan/PycharmProjects/chatbot-app/logs/core.log --workers 1

Issue:

ERROR rasa.core.agent - Could not load model due to Domain specification has changed. You MUST retrain the policy. Detected mismatch in domain specification. The following states have been

  • removed: prev_action_session_start
  • added:

I have extracted my model and In my domain file, there’s no prev_action_session_start state. I’m getting the above issue, can someone let me know what’s the issue here? Thanks in advance:slightly_smiling_face:

Hi @pavakalyankillari, did you train the model recently, and with the same version of rasa that you’re using to run it? What happens if you do retrain the model?

Hey @mloubser! Thanks for the reply.

Yes, I do retrain the model with the same version of rasa that I’m using to run it, and it didn’t work in the first attempt. Then I tried using a new virtual environment, re-installed all packages, and then it worked, Maybe some issue in the interpreter that I’ve used earlier. The issue got fixed. Thanks once again.
