I am currently in the fourth unit trying to launch the launch file in the topic after doing everything.
I get the following error:
ERROR: cannot launch node of type [topics_quiz.launch/script]: topics_quiz.launch
ROS path [0]=/opt/ros/noetic/share/ros
ROS path [1]=/home/user/catkin_ws/src
ROS path [2]=/home/simulations/public_sim_ws/src
ROS path [3]=/opt/ros/noetic/share

Any ideas?
