Rasa train doesn't create any models

Getting Started with Rasa

I am trying to start a new bot following the tutorial for Windows. If I can reach to the point where the model is trained. Contrary to what’s happening in the video I can’t interect with it:

So it seems that no models are being created.

Would a way around be to create my own models folder and copy and paste a model file one would be kind to give the reference to ?

I’ve tried downloading directly the RestaurantBot example. Yet when training I get a Module error:

Hi @antoinecomp what is the version of tensorflow you are using?

you can do pip list it will show all the installed packages, also please share your congif.yml file.
