@tboprob I highly recommend to tag me next time, please!

@tboprob

Rasa open source is not yet supported on Python 3.9.

Congrats if you were able to install conda now follow this thread and install Rasa Open source.

Note: Please follow the steps before Rasa X only first :slight_smile:

I wish you are now able to install ROS and Good Luck!
