Thanks for the share Rupendra and good luck with your project.
Do remember as soon as you update the rasa and rasa sdk to the latest version 2.x it can stop working rasa x (I wish I can be wrong but still just for your information) and rasa x is not compatible with 3.x.
@rupendra If in case you trying to update to 2.x i.e 2.8.1 please see this thread: Rasa X runs with several Errors & Warnings - #7 by vio_lovis
Have a nice day!
