Remote-SSH Unable to Select Interpreter

[mitchellgordon95]

Environment data

• VS Code version: 1.51.1
• Extension version (available under the Extensions sidebar): v2020.11.371526539
• OS and version: OSX High Sierra 10.13.6 (Local) CentOS Linux v7 (Remote)
• Python version (& distribution if applicable, e.g. Anaconda): Various (2.7, 3.6)
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): conda
• Relevant/affected Python packages and their versions: N/A
• Relevant/affected Python-related VS Code extensions and their versions: N/A
• Value of the python.languageServer setting: Jedi/Pylance

Expected behaviour

1. Enter a remote session over ssh (Remote-SSH: Connect to Host...).
2. Open a python file using Cmd-O.
3. Prompted to select an interpreter
4. Select one of the python interpreters available (conda env, or /usr/bin/python)
5. Yellow interpreter prompt disappears, auto-complete works as expected.

Actual behaviour

Yellow "Select Python Interpreter" prompt in bottom bar does not go away.
Auto complete does not work. (e.g. typing os.make does not suggest os.makedirs())

Additional Comments

It seems two potentially weird things are happening here:

1. Selecting an interpreter on a remote machine updates the local settings.json, not the remote settings.json

2. The python extension attempts to read settings.json on the remote machine from ~/.config/.... This would be correct if I was running Linux locally, but is incorrect when I am running a remote session. (Should be ~/.vscode-server/...)

Local Machine Settings (OSX): ~/Library/Application\ Support/Code/User/settings.json
Remote Machine Settings (Linux): /home/hltcoe/.vscode-server/data/Machine/settings.json
Non-existent Remote Settings: /home/hltcoe/mgordon/.config/Code/User/settings.json

When selecting an interpreter in the GUI, my remote machine settings remain unchanged:

{
    "python.pythonPath": "/opt/anaconda2/bin/python"
}

However, it (correctly) updates my local machine settings to this:

{
    ...
    "python.defaultInterpreterPath": "/home/hltcoe/mgordon/.conda/envs/huggingface/bin/python"
}

But it is checking neither of these when attempting to read the python path setting. So my current conclusion is that the python extension is not aware it is operating in a remote environment, which requires special considerations when updating and retrieving settings.

Interestingly, if I create the settings file it expects at /home/hltcoe/mgordon/.config/Code/User/settings.json with the following contents:

{
    "python.defaultInterpreterPath": "/usr/bin/python"
}

I get a different error:

But that's maybe a separate issue.

@karrtikr your advice would be welcome. 🙂

[karrtikr]

Thanks for the bug report! We investigate issues in order based on priority and severity, which includes the impact it has on your ability to use the extension to do productive work, and the number of people affected. If other users come forward and leave a comment demonstrating they are seeing/reproducing the problem then we will raise this issue's priority.

If you think your issue is more of a question or configuration problem rather than a bug, please ask on Stack Overflow with the visual-studio-code and python labels for help.

Thanks for your understanding and patience!

Hi @mitchellgordon95 👋 does the latest version of the extension fix the issue for you?

[karrtikr]

Can you try adding

    "python.experiments.optOutFrom": ["DeprecatePythonPath - experiment"],

in your user and remote settings, and see if it fixes the issue for you?

[brettcannon]

Because we have not heard back with the information we requested, we are closing this issue for now. If you are able to provide the info later on then we will be happy to re-open this issue to pick up where we left off.
