NameError: global name 'EventLoop' is not defined - pyglet

Question

I am trying to have python play an audio file for me. I am writing my code in enthought canopy.

import pyglet

sound = pyglet.media.load('song.wav')
sound.play()
pyglet.app.run()

When I run this I get an error: NameError: global name 'EventLoop' is not defined Also, the audio file plays the first note before the program errors.

I have no idea what is going on.

p.s. Do I need the pylab backend to be interactive for pyglet?

OS - osx 10.12.1 pyglet version 1.1.4-3

PyLab - No, you don't need that to be interactive. I'm wondering what OS and version of Pyglet you got installed? — Torxed

Make sure you haven't named any of your files the same thing as an important library module. — user2357112

I tried to reproduce the error but was unable to, although this library seems like it has a few other bugs too.

I did find that using the latest version of the library worked much better. My suggestion is to bump your version from 1.1.4 to 1.2.4.

pip uninstall pyglet
pip install pyglet==1.2.4
