Issue training carbon-bot from integrated version control

Hi,

Big fan of Rasa and the direction! I’m trying out rasa x for the first time this weekend. I have it running use the rasa-x helm chart on a digital ocean k8s cluster and have forked the carbon-bot demo app in order to import it to rasa-x using integrated version control. I was able to import carbon-bot successfully, but when I go to train, it seems to fail silently. When I tail the logs for the rasa-x service in kubernetes, I consistently see the below error message pop up when trying to do the training. Is there a sample app that works out of the box with rasa-x as far as training goes? Also, what do you recommend as the workflow for initiating training in rasa-x on either the rasa-demo app (sara) or carbon-bot?

Thanks again for a great project!

Could not complete training request as your training data contains retrieval intents of the form 'intent/response_key'. Please use the CLI to train your model (`rasa train`).

hi @AdamFerguson . firstly, nice debugging! You’ve run into a limitation there. We haven’t yet made the ‘train’ button in Rasa X compatible with retrieval intents, which I use heavily in carbon bot. My preferred workflow in any case is to train a model elsewhere and upload it to Rasa, rather than training on the production hardware running Rasa X.

We will get round to fixing this, but it’s not top priority at the moment.
