   I can confirm that this works with the current versions of

   • VS Code/Codespaces: 1.80.0
   • Python extension: 2023.12.0
   • Jupyter extension: 2023.6.1101941928

   Please be aware that code-sever (current version: 4.14.1, aka Code 1.79.2) relies on the Open VSX Registry, which currently provides

   • Python extension: 2023.10.1
   • Jupyter extension: 2023.3.100

   for code-server v4.14.1.

   ---

   Let us re-evaluate after @code-asher has updated code-server so it is based on Code 1.80.

   Most probably due to Pylance only being published to the VS Code marketplace.
   ℹ️ Pylance only runs with the official VS Code build.

   @cgebbe The situation regarding Pylance is not going to change.

   Please close this issue.

   As @benz0li mentioned, Pylance is only published to the VS Code marketplace; however, Jedi can be used instead of Pylance.

   jupyter-notebook-lsp.mp4

   Configure settings.json

   {
       "python.languageServer": "Jedi",
   }

   @OceanTrader1 thanks for this, I wanted to ask what is the difference between using Pylance vs Jedi? is there any tradeoff for making this change?

   EDIT: Also, Im able to get hover/definition feature working in notebooks but when I click on some library functions/classes it is not working and I'm not able to go to the definition, how can I fix it?
