[Matplotlib-users] memory usage with repeated imshow

[Tom D. <tdi...@ph...>]

I am using matplotlib pylab in association with ipython -pylab to show 
many large (~2000x2000 or larger) images.  Each time I show another 
image it consumes more memory until eventually exhausting all system 
memory and making my whole system unresponsive.

The easiest way to replicate this behaviour is with
a = ones((3333,3333))
imshow(a)

optionally

close()

and then

imshow(a)

again.  I am using ipython .10.1 and matplotlib 0.99.3.  Is there 
something I should be doing differently to avoid this problem?  Is it 
fixed in a later version?

Thanks,
Tom
