process had died, UR5 arm controller not working

edit

I am using Ubuntu 16.04 LTS and ROS1 kinetic version.

"https://github.com/lihuang3/ur5_ROS-G..." from this repository I cloned ur5_ROS-Gazebo and from "https://github.com/ros-industrial/uni..." this link I cloned universal robot repository in my "catkin_ws/src" directory which is my workspace for these packages then I ran 'catkin_make'. According to the ur5_ROS-Gazebo link I 'source devel/setup.bash' also 'source ~/catkin_ws/devel/setup.bash' , then I ran 'roslaunch ur5_notebook initialize.launch' to start the simulation the following errors occur:

Also the UR5 in the simulation does not work/simulate

What could be the problem here? I know the arm controller is not working but I dont knew that how to fix it? plesse help and advise.
