After #252325 was closed, I ran into the fact that autocompletion in IPython no longer worked. For example:

    elysium:~> ipython

    In [1]: cd tmp 
    Traceback (most recent call last):
    File "/usr/local/lib/python3.9/site-packages/IPython/terminal/ptutils.py", line 113, in get_completions
        yield from self._get_completions(body, offset, cursor_position, self.ipy_completer)
    File "/usr/local/lib/python3.9/site-packages/IPython/terminal/ptutils.py", line 129, in _get_completions
        for c in completions:

        completions = list(completions)
    File "/usr/local/lib/python3.9/site-packages/IPython/core/completer.py", line 1818, in completions
        for c in self._completions(text, offset, _timeout=self.jedi_compute_type_timeout/1000):
    File "/usr/local/lib/python3.9/site-packages/IPython/core/completer.py", line 1861, in _completions
        matched_text, matches, matches_origin, jedi_matches = self._complete(
    File "/usr/local/lib/python3.9/site-packages/IPython/core/completer.py", line 2029, in _complete
        completions = self._jedi_matches(
    File "/usr/local/lib/python3.9/site-packages/IPython/core/completer.py", line 1373, in _jedi_matches
        interpreter = jedi.Interpreter(
    File "/usr/local/lib/python3.9/site-packages/jedi/api/__init__.py", line 725, in __init__
        super().__init__(code, environment=environment,
    TypeError: __init__() got an unexpected keyword argument 'column'

Looking at the github repo for IPython, I found that there was a pull-request related to this: https://github.com/ipython/ipython/pull/12751

In essence, this modifies dependency for py-jedi as follows:

    jedi>=0.16,<0.18.0

Apparently, there has been a change in the py-jedi API.
The master branch for IPython was fixed, but this fix has not been backported to the 7.x branch.

So it seems to me that a rollback to 0.17 is in order until this is fixed in IPython.
