Rogue conda processes left running after closing vscode (do not use `conda run` for fetching env variables)

Applies To

• Notebooks (.ipynb files)
• Interactive Window and/or Cell Scripts (.py files with #%% markers)

What happened?

Steps to reproduce:

1. start vscode without any open file
2. open any .py file, with or without #%% markers
3. wait for Python task to show up in Task manager grouped under Visual Studio Code
4. Close VScode and wait for a few seconds
5. A rogue Python task remains running with high CPU and Power usage

Expected behaviour:

All python processes should close when exiting VScode

Attempted debugging

Disabling the jupyter extension in VSCode solves the problem.

Changing python language server settings as in the issue (with similar symptoms) in https://github.com/microsoft/vscode-python/issues/15586. i.e. adding "python.experiments.optOutFrom": ["pythonJediLSP"] and "python.languageServer": "Pylance" to settings.json. This did not solve the problem.

According to the task manager, the command line for the rogue processes is: C:\Anaconda3\python.exe "C:\Anaconda3\Scripts\conda-script.py" "run" "-n" "base" "--no-capture-output" "python" "c:\Users\***\.vscode\extensions\ms-python.python-2022.8.0\pythonFiles\get_output_via_markers.py" "c:/Users/***/.vscode/extensions/ms-pyt

For now you can install an older version of the extension before March as a workaround:

You can follow the prompts from “Extensions: Install Specific Version of Extension…” in the command palette:

Or you can open the extensions side bar, click on the settings for the Python extension and pick “Install Another Version…”:

The issue is no longer present after installing the v2022.0.1814523869 of the python extension.
