Importing python module from another ROS package. (Hydro)

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/Create%20your%20new%20rqt%20plugin

http://answers.ros.org/question/11794/how-can-i-use-custom-python-functions-in-other-ros-packages/

http://docs.ros.org/api/catkin/html/howto/format2/installing_python.html

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

echo $ROSPACKAGEPATH

/home/robin/catkinwsruben/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 flexboticscontrolnextageteleopps3.

################################################
## Declare ROS messages, services and actions ##
################################################

## To declare and build messages, services or actions from within this
## package, follow these steps:
## * Let MSG_DEP_SET be the set of packages whose message types you use in
##   your messages/services/actions (e.g. std_msgs, actionlib_msgs, ...).
## * In the file package.xml:
##   * add a build_depend and a run_depend tag for each package in MSG_DEP_SET
##   * If MSG_DEP_SET isn't empty the following dependencies might have been
##     pulled in transitively but can be declared for certainty nonetheless:
##     * add a build_depend tag for "message_generation"
##     * add a run_depend tag for "message_runtime"
## * In this file (CMakeLists.txt):
##   * add "message_generation" and every package in MSG_DEP_SET to
##     find_package(catkin REQUIRED COMPONENTS ...)
##   * add "message_runtime" and every package in MSG_DEP_SET to
##     catkin_package(CATKIN_DEPENDS ...)
##   * uncomment the add_*_files sections below as needed
##     and list every .msg/.srv/.action file to be processed
##   * uncomment the generate_messages entry below
##   * add every package in MSG_DEP_SET to generate_messages(DEPENDENCIES ...)

## Generate messages in the 'msg' folder
# add_message_files(
#   FILES
#   Message1.msg
#   Message2.msg
# )

## Generate services in the 'srv' folder
# add_service_files(
#   FILES
#   
#   
#)

## Generate actions in the 'action' folder
# add_action_files(
#   FILES

Thanks for your time

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 *

Asked by Chrissi on 2015-02-26 06:21:29 UTC

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

Asked by astur on 2015-02-26 09:31:28 UTC

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

Asked by astur on 2015-02-26 09:33:33 UTC

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

Asked by astur on 2015-02-26 09:52:15 UTC

Please uncomment this line

# catkin_python_setup()

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

That solve my problem,

Thank you
