Virtual environment from an unrelated directory gets selected

Behaviour

Expected vs. Actual

When I open a repo directory (I use the command line: code ~/<dirname>/), a seemingly random venv gets activated. What I want is: either a venv with a standard name (e.g. 'venv' or '.venv') in that repo (whether or not it's managed by git) is activated, or possibly a venv with a standard name from my home directory (e.g. ~/venv or ~/.venv). But what I get is a venv in some other repo that I might have last opened days or weeks ago gets activated. And sometimes no venv gets activated. I don't know how to control what happens, which is probably the most frustrating part.

Steps to reproduce:

1. Open VS Code on a repo, say ~/cpython.
2. In the shell, type 'code ~/peps/'.
3. In the new VS Code window that appears, create a shell window.
4. Observe that in that shell window, another repo's venv is opened, say ~/devguide/venv/.

Diagnostic data

• Python version (& distribution if applicable, e.g. Anaconda): 3.8.5
• Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Venv
• Value of the python.languageServer setting: Pylance

Output for Python in the Output panel (View→Output, change the drop-down the upper-right of the Output panel to Python)

Can I please get a screenshot of the interpreter list right after step 2 when ~/peps was opened? Use Python: Select Interpreter command:

Btw here's how we automatically choose environments: official documentation. If a local venv is present, we ideally should be choosing that.

[gvanrossum]

Here are screenshots of the top and bottom of that menu. FWIW today the outcome is different— it chooses ~/.venv, which is more reasonable. python.org/~guido

Sorry but I don't see any screenshots 😅 maybe because the comment was sent through an email?

[gvanrossum]

Using a phone. I will try again when I have my work laptop, Monday. python.org/~guido

Try these.

[karrtikr]

What I want is: either a venv with a standard name (e.g. 'venv' or '.venv') in that repo

I can confirm that "⭐" appears next to the interpreter which is expected to be selected (./venv/bin/python), so at least our guess is right. But our recommended interpreter was overridden by one of two things:

• "python.defaultInterpreterPath": Did you set this setting? If not, please remove it from "User settings" or settings.json in your repository.
• Previously configured interpreter using the menu. This can be cleared using Python: Clear cache and reload window command for all repos, or Python: Clear Workspace setting command for current repo.

[karrtikr]

My guess is, "python.defaultInterpreterPath" was previously inadvertently set in User settings, this can happen when working on an isolated Python file without opening a repo/project in VS Code.

We can look into improving this experience if that's the case.
