python - Mac OSX - AttributeError: 'FigureCanvasMac' object has no attribute 'restore_region'

Question

Walking through matplotlib's animation example on my Mac OSX machine - http://matplotlib.org/examples/animation/simple_anim.html - I am getting this error:-

File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/site-packages/matplotlib/animation.py", line 248, in _blit_clear
    a.figure.canvas.restore_region(bg_cache[a])
AttributeError: 'FigureCanvasMac' object has no attribute 'restore_region'

Does anyone who has encountered this before know how to resolve this issue?

Looks like it's a known (and unresolved at this time of writing) issue - https://github.com/matplotlib/matplotlib/issues/531

Answer 1

Just set

blit=False

when animation.FuncAnimation() is called and it will work.

For instance (from double_pendulum_animated):

ani = animation.FuncAnimation(fig, animate, np.arange(1, len(y)), interval=25, blit=False, init_func=init)
