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.
