I've just got a new mac, installs vscode, open a .ipynb file and presses the 'install jupyter notebook extension' pop up button. But now I'm getting this error when I try to run cells:

Failed to start Jupyter in the environment 'Python 3.9.6'. View Jupyter log for further details

Here's the log

I have looked all over the web but haven't been able to find any solutions to this. Others has reported similar issues, but their solutions didn't work for me.

  • Does the answer to [this question](https://stackoverflow.com/questions/70506366/failed-to-start-the-kernel-jupyter-in-vs-code) help? – 9769953 Feb 22 '23 at 10:41

    Also related: https://github.com/microsoft/vscode-jupyter/issues/12723 . Could be the same issue, if you can find the relevant log file and compare that with the linked issue. – 9769953 Feb 22 '23 at 10:43
  • @9769953 I've added the full log now, sorry. // Unfortunately it does not solve my issue – Quantizer Feb 22 '23 at 11:11
  • This solved the issue: ```python3 -m pip install jupyter notebook -U --force-reinstall``` – Quantizer Feb 22 '23 at 11:13
  • I think that was [one of the earlier suggestions in the GitHub issue tracker](https://github.com/microsoft/vscode-jupyter/issues/12723#issuecomment-1415700340), correct? It's a tad odd the issue is closed, if you recently had a fresh install and ran into exactly this issue. – 9769953 Feb 22 '23 at 18:30
  • Yes, it was one of the earlier suggestions. And you're right, it is actually odd. – Quantizer Feb 23 '23 at 07:35
