Comment (by zimmerma):
thanks to Alexander Kruppa, the solution is to undefine the environment
variables PYTHONHOME and PYTHONPATH:
{{{
import subprocess, os
def my_exec_factor(nbr):
cmd = ['/tmp/cado-nfs-2.1.1/factor.sh', str(nbr)]
my_env = os.environ
if my_env.has_key("PYTHONHOME"):
my_env.pop("PYTHONHOME")
if my_env.has_key("PYTHONPATH"):
my_env.pop("PYTHONPATH")
process = subprocess.Popen(cmd, stderr=subprocess.STDOUT,
stdout=subprocess.PIPE, env=my_env)
output, unused_err = process.communicate()
retcode = process.poll()
if retcode:
print "Output :"
print output
raise subprocess.CalledProcessError(retcode, cmd)
return output
}}}
