I’m quite confused with all the different parts of this: Rasa, Rasa-X, Rasa-NLU, Rasa-SDK. You have a line of code in your Installation guide to install both Rasa and and Rasa X:
$ pip3 install rasa-x --extra-index-url https://pypi.rasa.com/simple
But this doesn’t install the NLU and there’s no guide for installing the NLU anywhere I’ve checked on your site. You talk about NLU dependencies but not about installing NLU.
The problem is that when I install rasa-nlu separately, I get errors: apparently rasa and rasa-nlu require different versions of 3 packages and when I install rasa-nlu later, pip uninstalls new versions and reinstalls old versions of these packages, which then will no longer be what rasa requires.
