Sound alerts in Jupyter for code completion and exceptions

mindtrinket · August 7, 2017, 1:41pm

I often get distracted when trying to run large epochs or sections of code. Inevitably I forget that I was even training a model or get distracted for hours by my daughter. So I put together a quick sound alert that plays on the computer running Jupyter that I thought others might find helpful.

## Import up sound alert dependencies
from IPython.display import Audio, display

def allDone():
  display(Audio(url='https://sound.peal.io/ps/audios/000/000/537/original/woo_vu_luvub_dub_dub.wav', autoplay=True))
## Insert whatever audio file you want above

Execute the sound whenever you are at the end of code that takes a longer time.

allDone()

Working on also setting it up to play different sound alerts when exceptions are thrown while running code.

You may be interested to know you can easily create a jupyter extension that responds to start and end cell events. I set mine up to log the start time; elapsed time; and play a sound if execution time is more than 30 seconds.

simonm3/nbextensions/blob/master/cellevents.py

""" jupyter addin shows starttime, elapsedtime; sounds alert on cell finish
"""
import time
from IPython.core.magics.execution import _format_time
from IPython.display import display as d
from IPython.display import Audio
from IPython.core.display import HTML
import numpy as np
import logging as log

def alert():
    """ makes sound on client using javascript (works with remote server) """      
    framerate = 44100
    duration=.05
    freq=300
    t = np.linspace(0,duration,framerate*duration)
    data = np.sin(2*np.pi*freq*t)
    d(Audio(data,rate=framerate, autoplay=True))
    hide_audio()

I am having a little bit of trouble with the extension.

I have installed and enabled it with nbextensions.

For this minute long fuction, I dont see the time start or stop. It also did not make a sound.

Any advice? I’m not very familiar with juptyer extensions and that might be the trouble.

I don’t use the nbextensions tool so no idea how you add extensions to that.

I just pip install nbextensions [which is a completely different package with the same name!). Then enable with get_ipython().magic(‘load_ext cellevents’)

Your extension sounds really cool - can you please give a noob guide on how to use it?

Do I just put callevents.py in the folder with my python notebooks and then run get_ipython().magic(‘load_ext cellevents’) in the notebook? How do I make it work for all notebooks?
