问题
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

回答1:
The latest jedi (0.18) release is incompatible with the latest IPython release, see this discussion. The IPython next version (8.0) has a compatibility fix but was not yet released, while the previous version (7.x) just received a patch however was not released yet as of today.
The workaround is to downgrade jedi:
pip install jedi==0.17.2
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.
