Code for reproduction

Actual outcome
# ....ValueError: not enough image dataDuring handling of the above exception, another exception occurred:# ....actually, if we useplt.show() beforeani.save, this exception wont appear, but we will get only some last parts of the animation,example as this
Expected outcome
normally saved gif pic
example as this
