Giant IPKernelApp Error Using Hydrogen in Atom

Starting a few days ago, after months without issue, I began having a giant error box keep popping up when editing my code in Atom. I believe it is from the Hydrogen plugin, the weird thing is even with this error the code still runs and does what I want it too.

I created a new conda environment, installing only what I needed (pandas, geopandas, descartes, jupyter) and even when using the new environment in Atom I am getting this issue. I've tried upgrading ipykernel but it is already the most recent version.

Error Message

The latest jedi (0.18) release is incompatible with IPython 7.19 see this discussion. IPython: 7.20 (released Feb 1st 2020) and 8.0 (not yet released) have a compatibility fix.

The correct workaround at this time is to upgrade IPython:

pip install -U ipython==7.20

In future you can search for the final two lines of the trackback after removing all path fragments specific to your installation, this is searching for:

line 2029, in _complete completions = self._jedi_matches IPython/core/completer.py, line 1373, in _jedi_matches interpreter = jedi.Interpreter( jedi/api/init.py, line 725, in init super().init(code, environment=environment, TypeError: init() got an unexpected keyword argument 'column'

This will give you the relevant issues on GitHub in the first two Google result as for today.
