Using custom kernels in Jupyter through Nix

Notes

• Verify the kernel you are using has a ${path}/share/jupyter path, so it can be recognized by the command jupyter kernelspec list
• Run nix-shell, and if everything is successful, check if the kernels are listed

shell.nix

{ pkgs ? import <nixpkgs> {}, pythonPackages ? pkgs.python39Packages }:

let
  kernels = with pythonPackages; [
    ansible-kernel
    ilua
  ];

in pkgs.mkShell {
  buildInputs = with pythonPackages; [
    jupyterlab
    numpy
    scipy
    matplotlib
  ] ++ kernels;

  shellHook = ''
    # kernels
    export JUPYTER_PATH="${pkgs.lib.concatMapStringsSep ":" (p: "${p}/share/jupyter/") kernels}"

    echo Lets do some python
    alias start="jupyter lab"
  '';
}
