Background ZMQ IPython/Jupyter kernel

Run some IPython ZMQ kernel in the background, without an interactive shell. You can connect to that kernel remotely via ZMQ.

Installation (package is on PyPI):

pip install background_zmq_ipython

Usage:

import background_zmq_ipython
background_zmq_ipython.init_ipython_kernel()

The kernel will then run in the background in its own thread. The init will print some message similar to this on stdout:

To connect another client to this IPython kernel, use:
jupyter console --existing kernel-1111.json

Alternatives / related links:

• pydbattach

• Twisted SSH (example code)

• IPython.embed_kernel in a background thread (example code). This has some issues (e.g. here; messing around with sys.stdout etc).

• This code was introduced in this StackOverflow question, and also discussed in this IPython GitHub issue #8097, but it has become outdated, so this project provides a rewrite / updated code, and the goal was also an easy to install pip package.
