Error trying to get EIN working with Python/Elpy:

Greetings, ​ Whenever I run \`jupyter-notebook\` in a terminal, it opens and works just fine in a web browser, but, whenever I try to open a \`New Notebook\` with EIN, I get this error? ​ \`error in process sentinel: ein:insert-read-only: Wrong type argument: number-or-marker-p, t error in process sentinel: Wrong type argument: number-or-marker-p, t\` ​ [https://github.com/millejoh/emacs-ipython-notebook/issues/829](https://github.com/millejoh/emacs-ipython-notebook/issues/829) ​ \^ Above is the github issue with more context, thanks in advance for the help.

For now I'll just open jupyter notebooks in a web browser to develop projects until I figure out how to get it working in Emacs with EIN. I'd prefer to develop within Emacs, and with Elpy there is also auto-completion/documentation-on-hover, which would be very helpful while developing Python Jupyter projects.
