Hi guys, first time posting here so please be gentle. I'm trying to load a custom world into gazebo using the roslaunch command but it doesn't work. I'm not sure what went wrong because Gazebo DOES actually launch but it doesn't display my world. I followed everything the tutorial has said but still can't do it. I tried to upload a picture of my code but it says I need more than 5 karma to upload... If anyone knows how to upload their code please let me know

<<launch>
<include file="$(find gazebo_ros)/launch/empty_world.launch">
<arg name="world_name" value="(find try_description)/Worlds/Obstacle_Course.world"/>
<arg name="debug" value="True" />
<arg name="gui" value="True" />
<arg name="paused" value="True"/>
