[Matplotlib-users] Using blit=True in matplotlib.animation

[Peter R. <pe...@pe...>]

I’m on OS X, trying to write a multi-slider-controlled animation. If I have blit=True in the call to matplotlib.animation,
I get this message

matplotlib.animation.BackendError: The current backend is 'MacOSX'
and may go into an infinite loop with blit turned on.  Either
turn off blit or use an alternate backend, for example, like
'TKAgg', using the following prepended to your source code:

import matplotlib
matplotlib.use('TKAgg’)
=====

When I make this change  I still get the same error message, whether blit is set True or False. 
At least when blit=False the animation runs, which I can live with for the moment.
