Resource not found: simulation_gazebo

edit

I'm in a problem when running a world in gazebo. My "world.launch" file:

<launch>

<arg name="robot" default="machines"/>

<arg name="debug" default="false"/>

<arg name="gui" default="true"/>

<arg name="headless" default="false"/>

<arg name="pause" default="false"/>

<include file="$(find gazebo_ros)/launch/empty_world.launch">

<arg name="world_name" value="$(find my_worlds)/worlds/world01.world"/>

<arg name="debug" value="$(arg debug)" />

<arg name="gui" value="$(arg gui)" />

<arg name="paused" value="$(arg pause)"/>

<arg name="use_sim_time" value="true"/>

<arg name="headless" value="$(arg headless)"/> 

<env name="GAZEBO_MODEL_PATH" value="$(find simulation_gazebo)/models:$(optenv GAZEBO_MODEL_PATH)"/>

</include>

</launch>

My problem is in below:

Resource not found: simulation_gazebo

ROS path [0]=/opt/ros/noetic/share/ros

ROS path [1]=/home/quyet/simulation_ws/src

ROS path [2]=/opt/ros/noetic/share

The traceback for the exception was written to the log file

Could anyone give me answers ? Thanks for your help!
