I am using the new transforms version of MPL (the svn trunk), and found a memory leak in pcolor and pcolormesh. Be warned, I just reported a memory leak in the scikits delaunay package that Robert Kern was not able to reproduce, so it might be nice if someone could check this out. I am on Mac OS X, 10.4 using the latest svn versions of numpy and mpl. Here is the code that shows the leak:
from pylab import figure, close, ioff, savefig from numpy.random import rand ioff() for n in range(1000): fig = figure() ax = fig.add_subplot(111) data = rand(1000, 1000) ax.pcolormesh(data) savefig('foo.png') close(fig) print n I get over a gig in real and virtual memory (over 2 gig total) by n=30. I tried both pcolor and pcolormesh, as well as deleting various objects, clearing the axis, etc. -Rob ---- Rob Hetland, Associate Professor Dept. of Oceanography, Texas A&M University http://pong.tamu.edu/~rob phone: 979-458-0096, fax: 979-845-6331 ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
