Hello People , I am trying to execute train\_online.py for my chatbot POC. However it is failing due to some issue. Please help. I will attach supporting files.

Hey @Aditya07 where did you get this script from? And what version of Rasa are you on? ---

Hello @akelad , i got it from a github repository(it was referenced in YT video). rasa is latest version ---

This script is extremely old and using very outdated rasa versions. I would suggest using our CLI instead: [Command Line Interface](https://rasa.com/docs/rasa/user-guide/command-line-interface/) ---

Hello @akelad , Kindly suggest some good resources if i want to code all this out using jupyter notebook. I will use RASA docs but need some reference as to where to check it
