core service [/rosout] found process[tracker_command-1]: started with pid [2274] process[tracker_base_controller-2]: started with pid [2275] ERROR: cannot launch node of type [pi_tracker/tracker_joint_controller.py]: Cannot locate node of type [tracker_joint_controller.py] in package [pi_tracker]

tracker_join_controller.py is clearly in the bin of the package also.
