hi @sousablde ! using `train_core` directly is pretty advanced. Is there a reason you don’t simply use `rasa train` on the command line? ---

hi @amn41 I tired quite a few times to use it but I never got it to work (even followed a bit of the weatherbot tutorial) so I ended up continuing through what worked further in the process. I was able to fix it in the meantime, now just working on getting integration with a data set for it to actually work. ---
