vscode-jupyter: Vscode Jupyter Notebook Error: Fail to start the Python Kernel. Jupyter server crashed. Unable to connect Error code from Jupyter: 1

Environment data

Migrated from Macbook Pro mid-2015 to Macbook Pro M2

  • VS Code version: 1.75.0
  • Jupyter Extension version (available under the Extensions sidebar): 2023.1.2000312134.
  • Python Extension version (available under the Extensions sidebar): 2023.2.0.
  • OS (Windows | Mac | Linux distro) and version: MacOS Ventura 13.2
  • Python and/or Anaconda version: 3.6.4/1.8.0
  • Type of virtual environment used (N/A | venv | virtualenv | conda | …): Conda
  • Jupyter server running: Local | Remote | Local

Expected behaviour

Tried to select different python interpreter and set the flags in user settings per recommendations. I even uninstalled vscode and reinstalled the version for Apple silicon.

Actual behaviour

It ran fine in my older macbook pro mid-2015 intel based, but it’s running into issues with the following errors. I pasted the entire output log in the “Log” section of this issue report.

Failed to start the Kernel.

Jupyter server crashed. Unable to connect.

Error code from Jupyter: 1

[W 2023-02-02 18:26:30.449 LabApp] ‘notebook_dir’ has moved from NotebookApp to ServerApp. This config will be passed to ServerApp. Be sure to update your config before our next release.

[W 2023-02-02 18:26:30.449 LabApp] ‘config_file’ was found in both NotebookApp and ServerApp. This is likely a recent change. This config will only be set in NotebookApp. Please check if you should also config these traits in ServerApp for your purpose.

Steps to reproduce:

[NOTE: Self-contained, minimal reproducing code samples are extremely helpful and will expedite addressing your issue]

  1. Open a jupyter notebook and run the first cell, and you will get the error, and the log is pasted at the bottom.

I had the same error and tried basically everything I could find online to fix it. After finally just force reinstalling it worked for me.
