I'm producing series of plots (spectograms) in a program loop using imshow
and saving each plot to .png. Even though I close() each plot after each
savefig(...), the memory does not appear to be freed up, and the memory
useage goes up and up as the program runs (and stalls the computer as it
thrashes the page file).
This is the essence of the code:
for i in range(..):
pylab.imshow(logPSDs[i]...)
pylab.colorbar()
pylab.savefig(plotName[i])
pylab.close()
Is there anything that I should be doing to stop this memory "wastage"?
(The plots themselves are fantastic!)
