Problem matplotlib animation

Dieses Issue hat noch niemand übernommen.

Dear all,
I have tried to make an animation with jupyter-matplotlib. It has worked, but despite the repeat=False flag it just repeats forever. The example is taken from a tutorial. This does not happen if I just use the code as a script.
```
%matplotlib widget

import numpy as np
from matplotlib import pyplot as plt
from matplotlib import animation

# First set up the figure, the axis, and the plot element we want to animate
fig = plt.figure()
ax = plt.axes(xlim=(0, 2), ylim=(-2, 2))
line, = ax.plot([], [], lw=2)

# initialization function: plot the background of each frame
def init():
line.set_data([], [])
return line,

# animation function. This is called sequentially
def animate(i):
x = np.linspace(0, 2, 1000)
y = np.sin(2 * np.pi * (x - 0.01 * i))
line.set_data(x, y)
ax.set_title(str(i))
return line,

# call the animator. blit=True means only re-draw the parts that have changed.
anim = animation.FuncAnimation(fig, animate, init_func=init,
frames=200, interval=20, blit=True,repeat=False)

# save the animation as an mp4. This requires ffmpeg or mencoder to be
# installed. The extra_args ensure that the x264 codec is used, so that
# the video can be embedded in html5. You may need to adjust this for
# your system: for more information, see
# http://matplotlib.sourceforge.net/api/animation_api.html
anim.save('basic_animation.mp4', fps=30, extra_args=['-vcodec', 'libx264'])
plt.show()
```

Thanks a lot!

Beginne damit, den bereitgestellten Notebook-Code mit `%matplotlib widget` auszuführen, und vergleiche ihn mit demselben Code als Skript. Untersuche, warum `repeat=False` ignoriert wird, und überprüfe, dass die Animation nach den angeforderten 200 Frames stoppt.
