[Matplotlib-users] cbook.report_memory IOError

[K.-Michael A. <kmi...@gm...>]

Hi!

I have just run an old code that I believe was working before on OSX.
I am trying this with matplotlib 1.2.1 on an OSX EPD running Python 2.7.3


In [1]: from matplotlib.pylab import *

In [2]: import matplotlib.cbook as cbook

In [3]: data = ones((1500,1500,3))

In [4]: imshow(data)
Out[4]: <matplotlib.image.AxesImage at 0x109d343d0>

In [5]: ax = gca()

In [6]: print cbook.report_memory()
---------------------------------------------------------------------------
IOError                                   Traceback (most recent call last)

   1210     elif sys.platform.startswith('darwin'):
   1211         a2 = Popen('ps -p %d -o rss,vsz' % pid, shell=True,
-> 1212                    stdout=PIPE).stdout.readlines()
   1213         mem = int(a2[1].split()[0])
   1214     elif sys.platform.startswith('win'):

IOError: [Errno 4] Interrupted system call

First I thought, maybe this doesn't run in IPython for a reason, but 
trying it as a script also fails:

(general_dev+)[maye@lunatic ~/Dropbox/src/pymars]$ python imshow_test.py
Traceback (most recent call last):
  File "imshow_test.py", line 7, in <module>
    print cbook.report_memory()
  File 
"/Library/Frameworks/EPD64.framework/Versions/7.3/lib/python2.7/site-packages/matplotlib/cbook.py", 
line 1212, in report_memory
    stdout=PIPE).stdout.readlines()
IOError: [Errno 4] Interrupted system call


Is this cbook recipe maybe broken?

Best,
Michael
