I guess before I compile this node in ROS with catkin_make, I need somehow install and compile the jetson-inference project on TX2. Is that correct?

I have similar problem and I did "sudo make install" for the jetson-inference package, but still get the problem:

@robotlinker if you pull from master again, this should be fixed now in commit 0f5a6b

[robotlinker]

Thank you! This fixed the problem.
