Hello
I have encountered memory leak when using pylab.figure(), pylab.show(),
pylab.close(). I expected pylab.close() to flush the memory but this was not
the case. what am i doing wrong? Thanks in advance
Below is simple example
import os, sys, time
import gc
import matplotlib
matplotlib.use('TKAgg')
import pylab
import matplotlib.cbook as cbook
pid = os.getpid()
a2 = os.popen('ps -p %d -o vsz' % pid).readlines()
print 'memory before all figures the figure is drawn: ' + str(a2[1])
pylab.ion()
fig_list = []
for i in range(10):
fig_list.append(pylab.figure())
val = cbook.report_memory(i)
print i, val
pylab.show()
for fig in fig_list:
pylab.close(fig)
gc.collect()
print 'uncollectable list:', gc.garbage
a2 = os.popen('ps -p %d -o vsz' % pid).readlines()
print 'memory after all figures are closed : ' + str(a2[1])
******results******************************
memory before all figures the figure is drawn: 35424
0 4981
1 4981
2 5493
3 6005
4 6005
5 6517
6 6517
7 7029
8 7541
9 7541
uncollectable list: []
memory after all figures are closed : 80808
thanks
