python - AttributeError: 'FigureCanvasMac' object has no attribute 'restore_region' with matplotlib animation example on Mac OSX -

-

using example code matplotlib site:

i error:

attributeerror: 'figurecanvasmac' object has no attribute 'restore_region'

spammed in output animation loops. animation doens't display, , shows:

figure

this code works fine on windows pc, , other post find on this recommends set:

blit=false

to fix. still same error, not sure whether knows how can fix this. code i'm running is:

import numpy np import matplotlib.pyplot plt import matplotlib.animation animation  def update_line(num, data, line):     line.set_data(data[...,:num])     return line,  fig1 = plt.figure()  data = np.random.rand(2, 25) l, = plt.plot([], [], 'r-') plt.xlim(0, 1) plt.ylim(0, 1) plt.xlabel('x') plt.title('test') line_ani = animation.funcanimation(fig1, update_line, 25, fargs=(data, l),     interval=50, blit=true) #line_ani.save('lines.mp4')  fig2 = plt.figure()  x = np.arange(-9, 10) y = np.arange(-9, 10).reshape(-1, 1) base = np.hypot(x, y) ims = [] add in np.arange(15):     ims.append((plt.pcolor(x, y, base + add, norm=plt.normalize(0, 30)),))  im_ani = animation.artistanimation(fig2, ims, interval=50, repeat_delay=3000,     blit=true) #im_ani.save('im.mp4', metadata={'artist':'guido'})  plt.show()

thanks

must set blit=false in both funcanimation() , artistanimation() , code seems work fine. using python 3.4 , py34-matplotlib 1.5.2 macports.

ios - Is 'init' forbidden as *part* of a variable name? -

-
i spent 3 hours debugging error , in end narrowed down (i think) variable name. i using initmonths (initial months) caused unpredicatable errors when changed imonths worked! i can understand preventing use of init on it's own surprised if prevented part of variable name. bug or feature? it's not bug if it's related name being overlap. there's part of arc used know when retain counts should updated, , may running that. similar rules apply use new @ start of names (for same reason). it's easy , wise steer clear of using init @ start of names unless it's init function. i can imagine issue related arc getting involved shouldn't , takes while called shouldn't, weird. i expect issue else , name change had other effect. worst case means have memory issue , changing name has changed memory footprint of code you've moved bug somewhere else (or along lines).
