I eventually got jupyter-connect-repl to work by tracking down one of the kernel-mumble-mumble.json files in ~/.local/share/jupyter/runtime, e.g. kernel-eed594bc-6480-40b4-b8e2-4c56d2f6bf29.json.

I still don't quite understand what you wrote above. OTOH, from my
intuitive point of view, it seems that emacs-ipython-notebook is more
powerful then emacs-jupyter.
