extipy

Kernel manager for connecting to IPython kernels started outside of Jupyter.

Installation

pip install extipy

Quick start

jupyter notebook \
  --NotebookApp.kernel_manager_class=extipy.ExternalIPythonKernelManager \
  --Session.key='b""'

Note the --Session.key='b""' disables message authentication. This is necessary for now as I have not figured out how to fixup the authentication key associated with the current session.

Use case

The purpose of this kernel manager is to allow a jupyter notebook to communicate with an IPython kernel started outside of jupyter. The use case in mind is that you have an external python program which calls IPython.embed_kernel() or IPython.start_kernel().

Once you have created an IPython kernel in this way, hitting New Notebook in the jupyter notebook interface will trigger extipy to guess the kernel and connect to it.

How it works

This kernel manager lets Jupyter create a brand new kernel like normal. Then it looks in your runtime directory (should be ~/Library/Jupyter/runtime/ on mac) for the most recently modified kernel-*.json file and connects to it.
