@vijaynchakole can you please share me the rasa version rasa --version

@vijaynchakole a quick fix:

delete .db database file ‘events’ and ‘rasa’ and it will work and .db file automatic created as you run rasa x.

If you have any new error, do share with me, else close this thread with the solution for other. Good Luck!

@nik202 I am using Python Version 3.8, Rasa Version : 2.6.2, Rasa X Version : 0.40.0

where I can find these(events.db and rasa.db) files for deleting…I have searched them but didn’t get their location path

4

@vijaynchakole I mentioned when you run rasa x it will automatically created and you will see the rasa x running in your default web browser, I’d suggest use Chrome as your web browser.

5

When I run rasa x command …then it throws error…it is not opening in the default browser

6

@vijaynchakole share again rasa version using rasa --version

8

Rasa Version : 2.6.2

Minimum Compatible Version: 2.6.0

Rasa SDK Version : 2.8.1

Rasa X Version : 0.40.0

Python Version : 3.8.0

Operating System : Windows-10-10.0.14393-SP0

Python Path : c:\programdata\anaconda3\envs\rasa_bot\python.exe

9

@vijaynchakole can you please update rasa 2.6.2 to pip install rasa==2.8.1 and rasa x to 0.39.3

10

@vijaynchakole

I’d recommend to create a fresh conda environment with python 3.8 and follow the step

`pip install rasa==2.8.1`
`pip install rasa-sdk==2.8.1'

check version rasa --version its install or not

then

pip install rasa-x==0.39.3 --extra-index-url https://pypi.rasa.com/simple

check rasa version rasa --version its install or not

You will see some error : ImportError: cannot import name ‘RowProxy’ from ‘sqlalchemy.engine’ Install

pip install SQLAlchemy==1.3.22 should fix it

If sanic related error: pip install sanic-jwt==1.6.0

delete .db if is showing alembic issue.

Good luck! I hope this will solve your issue.

Thank you…I will follow the procedure and update you…thanks you

@vijaynchakole no worries, I know this will work for you!
