yeah i did try to specify python 3.6.8, got the error below 
(installRasa) C:\Users\Cyrus\Documents\Rasa_Projects\new>rasa init
Welcome to Rasa! 
To get started quickly, an initial project will be created.
If you need some help, check out the documentation at Introduction to Rasa Open Source.
Now let’s start! 
? Please enter a path where the project will be created [default: current directory] .
Created project directory at ‘C:\Users\Cyrus\Documents\Rasa_Projects\new’.
Finished creating project structure.
? Do you want to train an initial model? 
Yes
Training an initial model…
Training Core model…
