ros - how to add or use tfx python module for catkin? -

-

i download repository [ https://github.com/simon0793/pr2_simu... ] using catkin_workplace when ever run python code

python simulation_one_motion_queue.py

every time error comes tfx not found as;

raise resourcenotfound(name, ros_paths=self._ros_paths) rospkg.common.resourcenotfound: tfx ros path [0]=/opt/ros/indigo/share/ros ros path [1]=/home/mudasser/p/src ros path [2]=/opt/ros/indigo/share ros path [3]=/opt/ros/indigo/stacks

that means package tfx not found. make sure on ros_package_path. can try if added in path running 

$ roscd tfx

that should bring package directory. otherwise have search , include yourself. (worst case, tfx package not installed, have install first).
