Issues trying to get elpy to work correctly with emacs-ipython-notebook:

Hello there, Looking at the faq section of this repo: https://github.com/millejoh/emacs-ipython-notebook#faq , It says that elpy is the official supported module for emacs-ipython-notebook, but I'm having trouble getting elpy to work with ein. Here's the link to the issue that I'm having, thanks in advance for the help!

https://www.reddit.com/r/emacs/comments/pe7c24/im_having_trouble_getting_the_elpy_python/

And, here's the elpy error that was thrown, and the .emacs config for ein :

Note: I'm currently running python version 3.9.6, but I don't think that has anything to do with this issue? I'm guessing that my issue has to do with this .emacs config?

` ein: [info] ein:jupyter-process-lines: jupyter exited with status 1
