Rasa X says training failed even though it didn't

Version: Rasa X 0.37.1 Rasa-X Helm Chart installation

    # tag refers to the Rasa X image tag
    tag: "0.37.1"
# rasa: Settings common to all Rasa containers
    # tag refers to the Rasa image tag
    tag: "2.3.1-full"

When I set a model to train over the UI (Training → Update Model → Train Model), I get an Error Message telling me training failed and nothing else:


But if I check the logs in the production container, I see that the training keeps on going.

If I check in the Rasa X Models section after a while I see a new Model there. If I activate it, it works perfectly even though it “Failed”.

Same with me.

Rasa X 0.39.3 en Rasa 2.4.3-full, Openshift installation

  1. Rasa X, training reports “failed”
  2. After a few minutes model shows up in model tab
  3. I activate the new trained model (that was reported failed!)
  4. Conversations perform as I was expecting

So, eíther is there some treshold for this failure signal to appear , or it is a bug?

Note: On CLI at linux server, model training with same traningdata and config gives me no training failor. I only get one warning, when validating the data, i.e. the retrieval utterance has got no matching response (known bug, see Reponse validation gives incorrect warning for sub-intent responses · Issue #8070 · RasaHQ/rasa · GitHub)

I also get a warning about a retrieval intent:

UserWarning: Action 'utter_faq' is listed as a response action in the domain file, but there is no matching response defined. Please check your domain.

This is probably related then.

Has anybody who read this posts a comment, tip, reply?

I’ve upgraded Rasa-x to 0.40 and OS to 2.6 and the problem got worse. Now I get the “Training failed” message, but the model doesn’t appear in the models list after a while . I tried to do some digging and found following errors and logs.

  1. In the browser dev tools:

  1. In the ingress-controller logs: ​

Note that at the time the ingress-controller logs a 504 (Gateway Timeout) there has not been a response from rasa-x-nginx yet.

The 500 (Internal Server Error) logged by the rasa-x-nginx is probably unrelated. It only started happening recently and happens when the rasa-x-worker pod crashes (17 minutes later). I will open a separate post about this.

The ingress was throwing the timeout, a simple annotation fixed the issue of the 504:
