Expected behaviour

In ipynb files, on hover, showing documentation pop-up

Actual behaviour

Right after VSCode 1.52 update , on hover documentation pop-up stopped working, nothing pops up. I have downgraded from 1.52 to 1.51.1 and bug has been solved.

Thanks @canersnli , I am able to repro this in stable.

[greazer]

Sounds like a regression.

[luiztauffer]

so, it looks like #4299 was merged and possibly solved this? When is a patch release planned?

[rchiodo]

Sometime this month I believe.

I found that I was having autocompletion error in Ipython and Jupyter and found this Issue: ipython/ipython#12740

pip install jedi==0.17.2 solved for me, also within VSCode

Thanks for the advice but it didn't work for me.

Validated with numpy documentation popup in debug bits.

Unfortunately hover pop-up documentation still does not work on VS Code 1.53.2
On top of that, when I downgraded to 1.51.1 to recover pop-up documentation, surprisingly it didn't work either.

Then I switched between VS Code 1.50.1 - 1.51.1 - 1.53.2 and all language servers ( Pylance, Jedi, Microsoft) combinations but I couldn't recover hover documentation pop-up.
@joyceerhl Can you please share working versions of anaconda, python and extensions ? Any other suggestions are welcome aswell.

Edit: After switched between versions and tried all combinations, finally when I upgraded VS Code from 1.50.1 to 1.51.1 hover documentation pop-up worked on Pylance language server. I think I will stay on 1.51.1 for a while :)

I am on VS Code 1.53.2 (Win 10) and I hover pop-up documentation is not working for me either while trying to write Python code.

[arribass]

I 'm on VS Code 1.54.1 and hover pop-up docs are not working either. Is there any solution in this topic? Insiders works fine in this matters.

[rchiodo]

@oag335 and @arribass can you log new issues? It's not clear whether you're talking about ipynb files, whether or not you have pylance installed, and what UI you are seeing this in (pylance is required for the new native notebook UI).

[arribass]

I have pylance and I'm using an ipynb file. This is what i see when i try to get the docstrings from a function inside a modelu.
The first one is from VS Code Insiders which works pretty fine.

[rchiodo]

Yeah I repro that too. Your best bet is to use insiders. We're moving to that new UI eventually so we likely won't fix this in the old UI.

[arribass]

Okey, in insiders it only works properly when coding on the same cell you have imported the module. If you try to get the docstrings in any other cell it won't show up.

[rchiodo]

Weird. That sounds like a separate issue. Not sure why the separate cell would matter. As far as the language server is concerned, the entire notebook is one big py file. I'll log a separate issue. I repro this too.

[arribass]

Thanks. Where can I find that issue? So I can post some snaps with the errors.
