Hi @galandeshridhar,

Are you still seeing this issue? I’m seeing this happening for me as well. I tried upgrading to Rasa v1.3.6 but still seeing it. I’ve had no issues prior to this week. The only change I’ve recently introduced to my project is I’m trying to implement a custom component. Anyone else able to help with this issue?

Edit

Looks like the custom component I added was causing this error. Don’t mean to hijack the thread, but is there something I’m supposed to add to the domain when using a custom component?

Thanks

hi @Mthandazo42 @sihsob @j.mosig @galandeshridhar, I also faced the same issue, Initially I was not able to trace the error but then I figured out what went wrong:

  • I had made changes to my NLU data and my config.yml file and then I had just trained my nlu model using rasa train nlu command
  • then I had started my bot using rasa run -m models --enable-api --cors "*" --debug command and then I got the above error : No policy ensemble or domain set. Skipping action prediction and execution
  • then I figured out that I haven’t trained my rasa core model again just I had trained rasa nlu model
  • so again I retrained my bot using the rasa train command
  • and finally the error was resolved :slight_smile:

I hope this helps :wink:

@dsakalasooriya You still get the “No policy ensemble or domain set” error after rasa train and rasa run ...?

20

yes, So I re-create the project then the error is disappeared

It seems like your Policy model isn’t trained before NLU model, so the model.zip has no policy when reply to inputs. Excute rasa train to see if Policy model trained correctly, if not, delete all the trained models, use rasa train again.
