Interpreter shown in the status bar is not the selected one on MacOS

Environment data

• VS Code version: 1.57.0-insider commit 54d33cf
• Extension version (available under the Extensions sidebar): 2021.5.821509413-rc
• OS and version: macOS Big Sur 11.2.3
• Python version (& distribution if applicable, e.g. Anaconda): 3.10.0a5 (global), 3.6.9 venv
• Type of virtual environment used (N/A | venv | virtualenv | conda | ...): venv
• 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: Pylance

Expected behaviour

Interpreter shown in the status bar should be the selected interpreter.

Actual behaviour

Interpreter shown is whatever the extension could find (it's not even the interpreter I use in python.defaultInterpreterPath and I opted into all experiments), in this case /usr/local/bin/python3.

Notes:

• Opening a new terminal will activate the correct interpreter.
• Selecting a different interpreter in the quickpick will update the status bar to the correct one.
• Opening another Python file will also update the status bar.

Note the difference between the interpreter in the bottom left, and the current interpreter in the quickpick:

Steps to reproduce:

1. Open a Python project, install the extension, reload the window and wait for the extension to activate
2. Notice that the interpreter shown in the status bar is not the one selected for the project

Need to investigate to see if it's a mac-only issue.

[stevetwist]

Not sure if this is helpful, or what additional information I can provide, but I am experiencing this exact behavior on Windows 10.

When I first open a workspace the interpreter shown is a random interpreter VSCode found (it's not set for any of my workspaces). Opening another file then updates to display the correct interpreter, set for my workspace. From that point on (in the session) everything is fine.

Thanks,
Steve

[kimadeline]

Yep it is! Thanks for confirming that it doesn't happen only on macs @stevetwist!

[kimadeline]

Introduced by #15971

[karrtikr]

Could be related: #16291. Can anyone confirm if this only happens when in DeprecatePythonPath experiment? i.e does #16291 (comment) help?

[kimadeline]

Happens when not in the DeprecatePythonPath experiment:

User belongs to experiment group 'pythonDiscoveryModule'
User belongs to experiment group 'pythonDiscoveryModuleWithoutWatcher'
User belongs to experiment group 'pythonaacf'
User belongs to experiment group 'pythonTensorboardExperiment'
User belongs to experiment group 'CollectLSRequestTiming - control'
User belongs to experiment group 'CollectNodeLSRequestTiming - experiment'

[karrtikr]

@stevetwist Unfortunately I'm unable to reproduce this on Windows when not in deprecate python path exp. Can you try #16291 (comment) and see if it helps?

[stevetwist]

@karrtikr I can confirm that opting out of the 'DeprecatePythonPath' experiment fixed this issue for me, on Windows.

Thanks,
Steve

[karrtikr]

@kimadeline It seems this issue is only on Mac then so I cannot reproduce this. #16391 has just been merged which could potentially fix it, can you check if you can repro this on main?

[karrtikr]

Happens when not in the DeprecatePythonPath experiment:

I'm observe that for some reason we no longer log if the user is in DeprecatePythonPath - experiment, maybe it's a bug with the old framework. So we can't rely on logs to figure out which experiments user is in.

[kimadeline]

I can't reproduce it using Insiders version 2021.6.916495917-dev 🥳

Since this is fixed in Insiders @stevetwist you can either set up the Python extension to use one of our Insiders release channel with the python.insidersChannel setting (either weekly or daily should work), or you can wait for the next stable release of the Python extension later this month, which will include this fix.

Thank you!
