I followed tutorials and other questions relationated with this topic but I can't figure what I'm doing wrong.

http://wiki.ros.org/rqt/Tutorials/Cre...

http://answers.ros.org/question/11794...

http://docs.ros.org/api/catkin/html/h...

I sourced it ( devel/setup.bash in catkin_ws_ruben )

echo $ROS_PACKAGE_PATH

/home/robin/catkin_ws_ruben/src:/opt/ros/hydro/share:/opt/ros/hydro/stacks

and do also catkin_make clean

My problem:

I want to include this node on my my_module.py

 from flexbotics_control_nextage_teleop_ps3 import hiro_motion_savingpointsxml

and show me ImportError: No module named flexbotics_control_nextage_teleop_ps3.

Can you post the CMakeLists.txt and setup.py of the flexbotics_control_nextage_teleop_ps3 package? Also, try

from flexbotics_control_nextage_teleop_ps3.hiro_motion_savingpointsxml import *

Make sure you sourced devel/setup.bash in catkin_ws_ruben, that should put your package directory into PYTHONPATH (it's not clear from your post).

I try from flexbotics_control_nextage_teleop_ps3.hiro_motion_savingpointsxml import * and same error:

ImportError: No module named flexbotics_control_nextage_teleop_ps3.hiro_motion_savingpointsxml

Moreover, if i run both (rqt and my node) , without flexbotics_control_nextage_teleop_ps3 import hiro_motion_savingpointsxml it work perfect.

I did it some time ago "sourced devel/setup.bash"

echo $ROS_PACKAGE_PATH /home/robin/catkin_ws_ruben/src:/opt/ros/hydro/share:/opt/ros/hydro/stacks

Please uncomment this line

# catkin_python_setup()

In the CMakeLists.txt. otherwise the setup.py is never called.
