Install ipython with apt for more stable version. Jedi version 18.0 which is dependency of ipython breaks tab completion in ipython. Details here: https://github.com/ipython/ipython/issues/12745 — committed to NSO-developer/nso-docker by bdolenc 3 years ago

Ok that was easy. The Jedi release on 12/25 version 0.18.0 is breaking tab completion. pip install --upgrade 'jedi<0.18.0' gets you going.

For those looking for a quick fix, here’s @duysqubix’s answer, distilled into a command:
pip install -U jedi==0.17.2 parso==0.7.1

Ugh, can we please stop re-posting the solution and trying to take credit where credit is not due. The bleeding has stopped, a fix has been put in by @yurzo there is no need to re-post the fix.

When is a release with the fix coming?

timkofu on Jan 25, 2021

I found the culprit, it seems that installing a fresh ipython package pulls over the recent jedi==0.18.0 and parso==0.8.1 I downgraded jedi to 0.17.2 and parso 0.7.1 and this error went away.

Not sure of the overall fix, but hopefully this helps anyone for a temp solution. also this solution is found in #12740

@duysqubix solved for me, jedi==0.17.2 and parson==0.7.1

Thank you all who helped triage this problem and for providing workarounds while multiple fixes were in place. I’m grateful to the python community with how collaborative everyone can be to fix issues. I’ve also confirmed it’s working for me.

Thanks again for the all the hard work and keep on kicking butt. I love this tool.

detectable with flake8

This looks like a duplicate of https://github.com/ipython/ipython/issues/12740.

PeterJCLaw on Dec 28, 2020

backport PR is merged re-closing. I’ll start the release in a few minutes.

Carreau on Feb 1, 2021

Hum that is quite probable that another fix for jedi was not backported. I’ll try to find it. I haven’t had time to finish the release today but maybe tomorrow.

Many thanks for reporting and testing on both 7.x and master.

Might be one of 387da044fc or 95ab5c53c0 , or both.

Carreau on Jan 31, 2021

The actual missing imports for sys andtraceback that compounded the Jedi problem were also fixed here and here (h/t @Carreau)

I get same issue with auto-completion
