I just installed matplotlib 1.1.0. When I try the animation examples from
http://matplotlib.sourceforge.net/examples/animation/index.html, they just
flash up a window for a fraction of a second, and then terminate with no
message (animate_decay.py, strip_chart_demo.py, etc). Is this what they are
supposed to do? The documentation at
http://matplotlib.sourceforge.net/api/animation_api.html is very terse. When
I include the line
im_ani.save('im.mp4')
in animate_basic_example.py, I get this crash:
kbriggs@gold:~> python animate_basic_example.py
