What happened?

When I open a Notebook VS Code displays a message in the bottom right corner saying:

"The version of Python associated with the selected kernel is no longer supported. Please consider selecting a different kernel."

I'm using a Miniconda environment running Python 3.12.1.

I see this in my logs:

20:45:44.076 [info] Starting Kernel startUsingPythonInterpreter, .jvsc74a57bd06aa9a930b94239702003b1d5483aca273205853dc0a175a13e8fde3b74aafeaf.~/miniconda3/envs/python311/python.~/miniconda3/envs/python311/python.-m#ipykernel_launcher (Python Path: ~/miniconda3/envs/python311/bin/python, Conda, python311, 3.1.0) for '~/Code/crypto-quotes/notebooks/2. Data analysis/Analyse crypto quotes.ipynb' (disableUI=true)

Notice the "3.1.0". This is weird, because my Conda environment runs version 3.12. I also completely reinstalled Miniconda and setup multiple environments using Python 3.10, 3.11 and 3.12 and all give the same error.

And now I also completely removed and reinstalled VS Code and the issue persists.

This only started occurring suddenly today, so maybe it has to do with an upgrade of the extension or of VS Code...?

[luukburger]

Hmm, you also see the version being interpreted incorrectly in the kernel selector. Notice the 3.1...

Transferring to Python extension repo as this version information is returned by Python extensxion.
@karrtikr A similar issue was reported by @luabud , looks like the version information returned is incorrect at some stage.

Suffering from the same problem. It also appears to result in the kernel crashing after a while with miniconda, whereas with venv environments everything is OK.

[MarkSomogyvari]

I had the same issue. I rolled back to the previous jupyter extension version in VSCode (v2024.1.0), and that solved the problem for me for now.

For folks running into the issue, can you please provide the debug logs?

• Run Developer: Set log level command
• Select Trace
• Run Developer: Reload Window command
• Provide the output:

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