Python IntelliSense not working #6400

Closed rjpost20 closed 1 month ago

rjpost20 commented 2 months ago

Type: Bug

I have VS Code version 1.90.2 running on Windows 10. Recently I noticed that most if not all of my IntelliSense features are not working in my Python files.

Nothing happens when I hover over types (functions, variables, etc.) in Python files
Ctrl + Click on a type does nothing
Ctrl + Right Click results in the same menu as Ctrl + Left Click

I cannot jump to a type definition, view type definitions, etc. because of this. I have tried/checked:

Restarting VS Code
Disabling all extensions and re-enabling
Making sure Python + Pylance are installed
Making sure workspace is trusted
Making sure hovering is enabled
Making sure IntelliSense is enabled

Extension version: 2024.14.1 VS Code version: Code 1.90.2 OS version: Windows_NT x64 10.0.19045

UPDATE: It appears that the issue may be that latest version of Pylance (v2024.8.2) is not compatible with VS Code 1.90.2

@rjpost20 For python extension 2024.14.1 you need VS Code 1.93.0.

@rjpost20, it's possible that Pylance crashed. Can you please switch to our latest prerelease build and see if the issue goes away? There was a recent crash related to interactive windows. Perhaps you were hitting that.

If prerelease doesn't fix the issue, can you provide your "Python Language Server" log from the Output pane?

I experience this issue too since I upgraded Python extensions and VSCode. IntelliSense did work after upgrade but it stopped recently. I was not able to restore it. I use VSCode on MacOS (version 1.93.1) and work via remote tunnel on Ubuntu (code version 1.93.1). The extensions: Python v2404.14.1 and Pylance v2404.14.2. The python.languageServer is set to Default.

This is screenshot of what I see now: Screenshot 2024-09-26 at 08 18 11 If IntelliSense works then the imported packages show green. Hopefully you have a tip for me how to restore IntelliSense because I miss it. Thank you.

@JoostHazelzet can you provide your 'Python Language Server' output?

JoostHazelzet commented 1 month ago

Sure, but I don't have 'Python Language Server' in the dropdown list of Output. I only see 'JSON Language Server'.

rchiodo commented 1 month ago

What does your 'Python' output show? And what's your version of Pylance. 2404.14.2 is not a Pylance version number. That's likely the Python extension.

JoostHazelzet commented 1 month ago

My mistake, Pylance extension is on version v2024.9.2. Here is the Python output:

python.log

rchiodo commented 1 month ago

Are you sure your Pylance extension is enabled? And that the 'Language server' option for Python is 'Default' or 'Pylance'?

There should be a line like this in the 'Python' log:

2024-09-26 09:02:02.900 [info] Starting Pylance language server.

I noticed the error messages in the python log referring to a former Mamba environment. I decided for a reinstallation of VSCode and recreation of this Mamba environment which solved the issue for me. Pylance is working like a charm again. Thank you for your support.

Ok if you see the issue again, feel free to reactivate this issue.
