Instead of importing subprocess, other modules should use this as follows: from matplotlib.compat import subprocess This module is safe to import from anywhere within matplotlib. i(tabsolute_import(tprint_functionNtPopentPIPEtSTDOUTt check_outputcO@stdƒ‚dS(Ns!subprocess.Popen is not supported(tOSError(targstkwargs((sV/opt/xtal/ccp4-6.5-linux32/lib/python2.7/site-packages/matplotlib/compat/subprocess.pyR si˙˙˙˙iţ˙˙˙cO@s›d|krtdƒ‚ntdt||Ž}|jƒ\}}|jƒ}|r—|jdƒ}|dkr||d}ntj||d|ƒ‚n|S(s Run command with arguments and return its output as a byte string. If the exit code was non-zero it raises a CalledProcessError. The CalledProcessError object will have the return code in the returncode attribute and output in the output attribute. The arguments are the same as for the Popen constructor. Example:: >>> check_output(["ls", "-l", "/dev/null"]) 'crw-rw-rw- 1 root root 1, 3 Oct 18 2007 /dev/null\n' The stdout argument is not allowed as it is used internally. To capture standard error in the result, use stderr=STDOUT.:: >>> check_output(["/bin/sh", "-c", ...
