I got this error on my command prompt while running a python file to train file using rasa nlu

i'm currently using windows 10 rasa_core==0.8.2 rasa_nlu==0.11.4 python 3.6.7 PS: i downgraded both rasa and python as the modules names in rasa's recent version changed and python 3.8 didn't support rasa respectively.

I'm relatively new to coding. I would love to get some help here.

  • error shows that you have element `{'entities': [], 'intent': 'goodbye', 'text': 'Thank you for your help'}` without `start` - so it seems you have wrong data. You have to change it. – furas Jan 14 '20 at 18:50

Looks like you're using quite outdated version of Rasa, event before 1.0 The latest release is 1.7.0

You can find instructions for the upgrade here

Could you try to upgrade Rasa and try again?
