This can be caused by many reasons, some of them are as follows.

  1. Python executable path in vscode is incorrect

    • Solution: Configure the path to the python executable in settings.json. Remember to restart vscode after.
  2. The module is located in a non-standard location

    • Solution: Configure settings.json to include this location for autocompletion to work. An example (for Linux) used to add a custom module for the workspace:

      {
        "python.pythonPath": "/usr/bin/python",
        "python.autoComplete.extraPaths": [
          "${workspaceFolder}/customModule"
        ]
      }
      
  3. vscode was not launched from the active virtual environment

    • Solution: The path to the modules is set when a virtual environment is activated. Launch vscode from a terminal with the correct virtual environment activated

IntelliSense Not Working in VS Code (Python – Pylance) After August 2025 Update

Post:
Hey everyone 👋

Just wanted to share a quick fix for an issue I recently faced — maybe it’ll help someone else.

After updating VS Code in August 2025, my IntelliSense for Python completely stopped working. No auto-complete, no suggestions — it was really frustrating, especially with Pylance enabled.

Luckily, I found a helpful discussion on the official GitHub page that solved the issue for me.

🔗 If you're facing the same issue, check out this link for the full fix:

Hope it helps! If anyone needs more info or is still stuck, feel free to reply — happy to share what worked for me. 😊

Setting up Python3 Intellisense in Visual Studio Code | Alexander Swensen | Alexander Swensen
December 6, 2019 - Well not so much anymore. So I spent a few hours trying to figure this out. Turns out the native Python extension tries to use jedi for intellisense, but (at least in my configuration) it doesn't seem to work. Thankfully there is another alternative. Microsoft also develops the python-language-server package for vscode.

r/vscode on Reddit: [Python] IntelliSense stopped working for .PYC modules when using Pylance as a language server
February 20, 2021 -

Is there any settings that I can add to enable IntelliSense for .pyc modules ?

And by the way everything works fine when I switch to the Jedi language server.

I'm using Raspberry Pi OS, python3 with venv, and the module is RPi.GPIO.

Any help would be appreciated.
