While use multi-root workspace, avoid setup python interpreter in non-python project

[cuserdzy]

Type: Bug

Behaviour

Expected vs. Actual

I have a test monorepo project with multi-root workspace, here all two modules proj_a/ and proj_b/, the former one is a python project while the later one is golang project.
I use poetry for proj_a/ and the folder contains a .venv directory

In the .code-workspace file:

{
  "folders": [
    {
      "path": "proj_a"
    },
    {
      "path": "proj_b"
    }
  ],
  "settings": {
    "python.defaultInterpreterPath": "${workspaceFolder}/.venv/bin/python",
    "[python]": {
      "editor.defaultFormatter": "ms-python.black-formatter",
      "editor.formatOnSave": true
    }
  }
}

While I open the workspace, the vscode-python extension starts work and try to setup interpreter for both proj_a/ and proj_b/ and obviously it fails on proj_b/ with below error message in output.

  errno: -2,
  code: 'ENOENT',
  syscall: 'scandir',
  path: '/Users/***/Downloads/test_monorepo/proj_b/.venv/bin'
}

Alought the python extension can work on proj_a/ but the error message is quite massive and noisy while debug other issues.

If .venv only exists in a particular workspace, the following should serve you better:

"python.defaultInterpreterPath": "${workspaceFolder:proj_a}/.venv/bin/python"

Let me know if that helps, if not, we can look into other alternatives. Make sure to use Python: clear cache and reload command as well.
