Extension v2024.4.0 and v2024.4.1 create indefinite "Discover Python Interpreters"

[dokutoshi]

Type: Bug

Behaviour

Expected vs. Actual

Install v2024.4.0 or v2024.4.1 extension and the discovering Python interpreters run indefinitely. This also restarts the kernel periodically - a MAJOR PROBLEM when excecuting ML notebooks - lost variables imply retraining or reloading a pandas DF etc.
XXX

Steps to reproduce:

To stop the kernel from periodic restarts use v2024.2.1

Diagnostic data

• Python version (& distribution if applicable, e.g. Anaconda): 3.11.9
• Type of virtual environment used (e.g. conda, venv, virtualenv, etc.): Conda
• Value of the python.languageServer setting: Pylance

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

XXX

User Settings

languageServer: "Pylance"

Hi Leo Pimentel (@dokutoshi). Thank you for filing the issue. Can you set your log level to trace in command palette and share your Python output info accessible in output for Python?

[dcx]

I'm having this issue too, and there's nothing available in the Output dialog.

[anthonykim1]

Interesting..Does Clear Cache and reload Python extension fix the problem?
(Accessible via ctrl+shift+p) or cmd+shift+p on mac.

[anthonykim1]

Also wondering if problem persists in version below v2024.4.0

[dokutoshi]

I will look into this later today. Prescriptive measure include setting log level == 'trace' and cmd+shift+p On May 22, 2024, at 14:49, Anthony Kim ***@***.***> wrote: Also wondering if problem persists in version below v2024.4.0 — Reply to this email directly, view it on GitHub<#23452 (comment)>, or unsubscribe<https://github.com/notifications/unsubscribe-auth/ACNWBJOTDMYMQLMVSSOMG6TZDTSCVAVCNFSM6AAAAABH63ATVOVHI2DSMVQWIX3LMV43OSLTON2WKQ3PNVWWK3TUHMZDCMRVGUZDMNRRGI>.

Clearing the cache and reloading the window does solve the infinite running issue.

However, the reason i opened this ticket relates to this bug:

48 hours into testing, Discovering process starts up and terminates a running job. ML training takes weeks. What happened? Using VSCode worked for over 2 years in DL training. Now I can barely use it for a day without Discovering Python Interpreters appearing and halting training. Anthony Kim (@anthonykim1)

Leo Pimentel (@dokutoshi) Can you bring the requested logs and also check if same problem exists in version below 2024.4.0 that you have mentioned?

[dokutoshi]

Dealing with a related issue in Vscode Insiders that crashes Pylance and triggers Discovering Python Interpreters.
note the error using the -I flag in the Vscode code base.
Pylance Crash

For reference, here is the Python log output.

Sorry venting here but when the Discovery process starts, it is impossible to save the file.

Even Save As fails silently!
