@cnHeider It sounds like jupyter is not in Atom's PATH, therefore the jupyter kernelgatewaycommand used by atom-notebook is not spawning a kernel gateway instance.

  1. Run which jupyter or jupyter --paths to determine where your jupyter binary is located
  2. In Atom, run process.env.PATH and confirm that the path to your jupyter binary is included in Atom's PATH
  3. If it's not included, add it to atom-notebook's settings (Command Pallette > Settings View > View Installed Packages > jupyter-notebook > Path to jupyter binary

If it is included, confirm that jupyter and jupyter kernel gateway is installed: pip3 install jupyter jupyter_kernel_gateway
