@yuvaraj.palanisamy can you share the pip version for the same, or I’d recommend using pip==20.3 and trying to mention the rasa x version
pip install rasa-x==0.42.5 --extra-index-url https://pypi.rasa.com/simple
I’m not aware of this current version, but if you struggle installing the latest version please see this thread for an alternative solution for rasa x installation: Rasa X runs with several Errors & Warnings - #2 by nik202
Can you even share the rasa --version?
Hope this will help you.
