Moveit Python Demo causes [Errno 9] Bad file descriptor

edit

Hello ROS Community,

This is my first post to this forum. I am attempting to run the tutorial for moveit using python. Specifically the Move Group Interface/Python API tutorial. Sorry, my karma is not yet good enough to post links.

• I am running python 2.7.
• OS is Ubuntu 12.04
• ROS and ROS packages are installed using apt-get

I have created a package called my_youbot_moveit with a simple python script. The script contains the following:

import sys
import copy
import rospy
import moveit_commander
import moveit_msgs.msg
import geometry_msgs.msg

print("============ Starting tutorial setup")
moveit_commander.roscpp_initialize(sys.argv)
rospy.init_node('move_group_python_interface_tutorial', anonymous=True)

When I run the code

source ~/catkin/develop/setup.bash
rosrun my_youbot_moveit my_youbot_moveit.py

I get the error

Exception in thread Thread-3:
Traceback (most recent call last):
  File "/usr/lib/python2.7/threading.py", line 551, in __bootstrap_inner
    self.run()
  File "/usr/lib/python2.7/threading.py", line 504, in run

  File "/usr/lib/python2.7/socket.py", line 202, in accept
    sock, addr = self._sock.accept()
  File "/usr/lib/python2.7/socket.py", line 170, in _dummy
    raise error(EBADF, 'Bad file descriptor')
error: [Errno 9] Bad file descriptor

Please help me understand what is causing this problem and how to solve it.
