Hi everyone! When I try to init Rasa x in my project it throws the following error:

Sorry, something went wrong (see error above). Make sure to start Rasa X with valid data and valid domain and config files. Please, also check any warnings that popped up.

I think my data is valid, rasa data validate goes perfect and the Rasa shell & train are working perfectly so I don’t know what’s going on. I’ve tried upgrading Rasa and Rasa X following the compatibility matrix without success, getting the same error. Does somebody know how can solve this problem?

This is my current setup:

Rasa Version     : 2.4.3
Rasa SDK Version : 2.4.1
Rasa X Version   : 0.38.1
Python Version   : 3.6.13
Operating System : Linux-5.10.30-1-MANJARO-x86_64-with-arch-Manjaro-Linux
Python Path      : /home/joan/Desktop/VihrtualApp_Chatbot/venv/bin/python3.6

Solved: The error is specific to Python 3.6. Using 3.7 or above solves the issue. Thanks to hsm207 for the help. See the Github issue for more details.

Parul_Chaudhari · May 17, 2021, 5:59pm

I’m using Python 3.7, still facing this issue.

joancipria · May 18, 2021, 3:13pm

Which minor version? I’ve upgraded to 3.7.10 and is working for me on Manjaro:

Rasa Version      :         2.5.1
Minimum Compatible Version: 2.2.0a1
Rasa SDK Version  :         2.5.0

hey guys - still facing this same error ( Make sure to start Rasa X with valid data and valid domain and config files )

Using Python 3.8.10

Any ideas what’s going wrong ?

I have tried everyting:

Different versions of Python as well as rasa and rasa-x (keeping in mind the compatibility)
Conda installations, followed every step by YouTube Videos for both python 3.7 and 3.8

Is there a possibility that the issue is caused due to the conda environment? I recently deleted old Anaconda 3.7 and installed 3.8.8, which started causing this issue. So I don’t have a python venv anymore, I was using venv before conda and never faced this issue.

I had to delete Python, because I was doing Deep Learning tasks and somehow there should be only one python environment.

@Mansoor Now your issue is condo environment or installing Rasa X?

Mansoor · July 3, 2021, 12:32am

Huh, this issue was resolved by changing the stories.yml file.

There were some non English letter, specifically German Language such as: für

By changing it to fur resolved the issue…

But I also reinstalled anaconda2020 with python3.7.6, things were great back with this.

So I’m gonna keep it, and maybe use 3.8 in a different conda environment. And:

Rasa Version      :         2.6.2
Rasa SDK Version  :         2.6.0
Rasa X Version    :         0.40.0
Python Version    :         3.7.6
