Anaconda environments listed as 'base'

[Flottrant]

Type: Bug

Behaviour

Most of the conda environments in the automatic environment detection are listed as 'base' even though they show the correct path to the environment.
The VSCode terminal then only activates the actual conda base environment in the console.
Environments work correctly in independent terminals.

Steps to reproduce:

1. Open VSCode
2. Open command palette
3. Run the command Python: Select Interpreter

Diagnostic data

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

Hello @Flottrant Thank you for filing this issue.
Are you able to add:

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

in your settings.json and see if you can repro the same problem?

[Flottrant]

Hello @anthonykim1,
the issue seems to have disapeared completely after switching to version 2024.10.0 and back.
However, the same was not true for any version newer than 2024.10.0.

[anthonykim1]

@Flottrant Hello, when you search your setting and search 'native locator', is that set to native or js?

[Flottrant]

It is set to js

[Flottrant]

Setting it to native reproduced the issue.
This was with the "python.experiments.optOutFrom": ["pythonTerminalEnvVarActivation"] line added to the settings.json.

Hi,

I'm having the same issue with the latest versions of vscode and this extension. It seems like a regression. I have set to native and js and get the same results for both (although not sure if one time choice of native causes this issue to persist).

Please look into the issue of all anaconda environments being called "base", thank you!

[anthonykim1]

@karthiknadig I think you would have better context of how conda environments get differentiated in the select interpreter listing.

[karthiknadig]

We did a bunch of fixes for this recently so this should be addressed, if that is not the case please file a new bug with the logs from Output > Python locator, and screen shot of the interpreters list where envs are incorrectly marked as base
