Quickstart fails? Bug in the example?

I’m trying to run the examples at

the runstep that looks like this:

!python -m rasa_core.train -d domain.yml -s stories.md -o models/dialogue

print(“Finished training!”)

Hey @killedbylogin. Thanks for reporting this. You are getting the warning (which for sure shouldn’t be produced in a first place) which doesn’t break the code and you can still follow the tutorial. We will make sure to resolve the issue which causes the warning though.
