Package: jupyternotify
A Jupyter Magic For Browser Notifications of Cell CompletionThis package provides a Jupyter notebook cell magic%%notifythat
notifies the user upon completion of a potentially long-running cell via
a browser push notification. Use cases include long-running machine
learning models, grid searches, or Spark computations. This magic allows
you to navigate away to other work (or even another Mac desktop
entirely) and still get a notification when your cell completes.
Clicking on the body of the notification will bring you directly to the
browser window and tab with the notebook, even if you’re on a different
desktop (clicking the “Close” button in the notification will keep you
where you are).Supported browsersThe extension has currently been tested in Chrome (Version: 58.0.3029)
and Firefox (Version: 53.0.3).Note: Firefox also makes an audible bell sound when the notification
fires (the sound can be turned off in OS X as describedhere).Import the repoTo use the package, install it via pip directly:pip install jupyternotifyor add it to the requirements.txt of your repo.To install directly from source:gitclonegit@github.com:ShopRunner/jupyter-notify.gitcdjupyter-notify/virtualenvvenvsourcevenv/bin/activatepipinstall-rrequirements.txtjupyternotebookUsageLoad inside a Jupyter notebook:%load_extjupyternotifyAutomatically load in all notebooksAdd the following lines to your ipython startup file:c.InteractiveShellApp.extensions = [
    'jupyternotify'
]The .ipython startup file can be generated withipython profile create [profilename]and will create a configuration
file at~/.ipython/profile_[profilename]/ipython_config.py'. Leaving
[profilename] blank will create a default profile (seethisfor more
info).To test the extension, try%%notify
import time
time.sleep(5)OptionsNOTE: Currently options cannot be used with%load_extor the ipython
startup file instructions above.To load the magic with options, you should load it manually by doing the
following:importjupyternotifyip=get_ipython()ip.register_magics(jupyternotify.JupyterNotifyMagics(ip,option_name="option_value"))or add this to your ipython startup file:c.InteractiveShellApp.exec_lines=['import jupyternotify','ip = get_ipython()','ip.register_magics(jupyternotify.JupyterNotifyMagics(ip, option_name="option_value"))']The following options exist: -require_interaction- Boolean,
default False. When this is true, notifications will remain on screen
until dismissed. This feature is currently only available in Google
