Hi, I have a script that creates and saves figures in a loop. The memory is increasing at each figure and is not released back, rising a Memory error. I used the close() function on the figure object as well as gc.collect(), but no effect.
I searched on the net and found a similar problem at http://stackoverflow.com/questions/3623600/python-matplotlib-memory-not-being-released-when-specifying-figure-size. The problem here was solved using the close() function but in my case, as refered before, it doens't work (see code below). I'm using Python 2.6.6, matplotlib 1.0.1, WXagg as backend, on windows7. Thanks for help!
