Gazebo hangs up on launch

edit

I am trying to complete assignment 6 for the EdX class called Hello (Real) World with ROS – Robot Operating System. When I launch Gazebo using 'roslaunch hrwros_week6 hrwros_final_project.launch' It hangs up with the logo on the screen forever. I can't seem to figure it out. I am running it on Ubuntu 16.04 64 bit using ROS Kinetic. I have had Gazebo working for the other assignments and my other classmates have not posted about having this issue. I am using a singularity image of ROS provided by the instructors and have had Gazebo working for all other exercises. Here is the output when I try to run the launch file:

roslaunch hrwros_gazebo hrwros_pick_demo.launch
