How to solve "Jupyter Server Initialization Failed"?

I’m having trouble booting up Jupyter Lab.
Now I’m confronting the problem of Jupyter Server Initialization Failed.

I don’t know what the problem is exactly.
How to solve this problem step by step?

Hi @toshinakatsu this is an error screen of JupyterLab Desktop. There are a few possible causes; I can help you if you share the log files. You may be able to find a solution yourself by looking over existing workarounds in:

It is usually easier for maintainers to handle bug reports on GitHub (and a chance is that following the template of Sign in to GitHub · GitHub could have helped you to solve the issue yourself), but in case if you don’t have GitHub account here are the most important steps:

  • Start application from command line as jlab --verbose 4, wait until it settles
  • Copy-paste the logs from the following location:
    • on Linux: ~/.config/jupyterlab-desktop/logs/main.log
    • macOS: ~/Library/Logs/jupyterlab-desktop/main.log-
    • on Windows: %USERPROFILE%\AppData\Roaming\jupyterlab-desktop\logs\main.log
  • also, go to Help → About JupyterLab and let me know of the version number.

Thank you!

Hi @krassowski Thank you for your advice.
Referring to these links, I try to solve this problem.

If I still can’t solve, I think I share the log files on GitHub.
Thank you!
