Revision history [back]

I tested your code and it works for me (at least the import part).

I put some suggestions below:

source your ros setup

source /opt/ros/kinetic/setup.bash

check that people_msgs pkg is recognized by your setup:

rospack list | grep people_msgs

should give as result:

people_msgs /opt/ros/kinetic/share/people_msgs

if not, then install it:

sudo apt install ros-kinetic-people-msgs

This should solve your issue. Again, it works on my machine.
