whenever i run the listener python script i get only an out put saying usage:turtle_tf_listener.py follower_model_name model_to_be_followed_name help in this regard pls been trying to figure out why this is happening but no clue.
so turns out i also have to give the names of the models for the python script to work haha finally figured it out : )
Its asking you to execute the python script with extra arguments, in this case:
python turtle_tf_listener.py turtle1 turtle2
Have a look at the code and you will see in the main method that two arguments are asked for ;).
