Wrong python selected after select interpreter

[lorenzomammana]

Does this issue occur when all extensions are disabled?: Yes, partially I'm using remote development so I can't really disable that extension, this issue does not seem to arise when running in a wsl.

• VS Code Version: 1.100.0
• OS Version: Ubuntu 22.04.5 LTS (docker container)

Steps to Reproduce:

1. Attach to a remote container
2. Setup an environment (we use conda, e.g. conda create -n test python=3.10)

3. Select interpreter -> Select the new environment

4. which python -> To us it shows /opt/conda/bin/python, which is not the one used for the environment, the environment still looks activated, there's (test) before the username
5. Run conda activate test manually
6. which python -> $HOME/.conda/envs/test/bin/python, this is the what happend using vscode < 1.100.0

This is quite problematic as it seems that an environment is active when it's not causing missing dependencies etc..

@lorenzomammana Can you share your logs from Output > Python?

@karthiknadig
I've opened a repository called quadra, with an active environment called quadra.
From the log it seems that pyhton interpreter path is correct, but when running which python it still points to /opt/conda/bin/python

@lorenzomammana Can you try adding this to your User settings, reload VS Code and see if it helps.

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

[lorenzomammana]

This does seem to work!
