Hi @nik202 ,
thank you very much for the detailed instruction. You were right, I was following the steps from the Rasa Certification Workshop on Udemy. However, when I reached the point of installing rasa-x and I couldn’t get it running, I tried to incorporate some of the instructions I saw here in the Rasa Forum 
So, now I tried what you suggested
- conda create -n proto2 pyhton==3.8
- conda activate proto2
- pip install rasa==2.8.1
- pip install rasa-sdk==2.8.1
- rasa init → then I followed the instructions
- pip install rasa-x==0.39.3 --extra-index-url Simple Index
Unfortunately, this is where I get the following error:
Building wheels for collected packages: ujson
Building wheel for ujson (setup.py) … error

What would you suggest?
Thank you very much. Your help is appreciated
