Hello everyone, absolute newb in rasa and I keep getting an error when trying to train rasa.

this is the error message I am getting when running train_core() and I don’t know where it is coming from:

Any help would be greatly appreciated, thank you for your time.

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.

Same problem occurs while running “rasa train” command in command line

I had the same error , i found that of slots in the domain file was wrong indentation. Fix the indentation in domain file
