Extension fails to activate unnamed conda environments

[F1bos]

Description:

Extension is unable to activate unnamed conda environments created using the conda create -p command after the latest update. Previously, these environments were activated correctly. No changes were made to the environments themselves, only VS Code and the Python extension were updated. Named conda environments continue to activate without issue.

Steps to reproduce:

1. Create an unnamed conda environment using the following command:

   conda create -p ./env

2. Open a project folder in VS Code that uses this unnamed environment.
3. Attempt to select the environment as the Python interpreter for the project using the Python extension.

Expected behavior:

The Python extension should successfully activate the unnamed conda environment and correctly load its packages, as it did before the update.

Actual behavior:

The Python extension fails to activate the environment and displays an error message, indicating "EnvironmentLocationNotFound". The wrong Python interpreter may be selected, leading to issues with code execution and package resolution.

Logs:

}

Environment:

• VS Code version: Version: 1.93.0 (user setup)
• Python extension version: v2024.14.0
• Conda version: 24.7.1
• Operating System: Ubuntu 20.04.3 LTS in WSL 2

Additional information:

• This issue only occurs with unnamed conda environments. Named environments activate correctly.
• The issue appeared after updating VS Code and the Python extension today. Previously, unnamed environments worked as expected.
• It seems the problem might lie in the conda run command used by the extension. The logs show it's attempting to activate an environment named "env", but the unnamed environment doesn't have a name and is located at "./env", not "/home/USER/miniconda3/envs/env".

I have tried restarting VS Code and reinstalling the Python extension, but the issue persists.

Please investigate this issue and provide a fix to restore the ability to activate unnamed conda environments within the Python extension.

Hi @F1bos Thanks for filing this issue. Can you try adding:

"python.experiments.optOutFrom": ["pythonTerminalEnvVarActivation"],

to your settings.json and see if that works? Thanks

Hi.

This is what i have in Python extension logs:

This is what i got in terminal:

conda activate env

You can list all discoverable environments with `conda info --envs`.
