Error Gazebo - PX4-ROS2-Gazebo-YOLOv8

[Mojgan-arch]

Hi, I hope you are well. I have problem to see Gazebo scene after installing [PX4-ROS2-Gazebo-YOLOv8], Gazebo page appear but completely black. I have ROS2 Humble on my pc. I installed ROS2 before, so I did not just follow that part related to install Ros2, but I did all process step by step.

When I run this code in Terminal, Gazebo page appear in black scene.
(Terminal #2:
cd ~/PX4-Autopilot
PX4_SYS_AUTOSTART=4002 PX4_GZ_MODEL_POSE="268.08,-128.22,3.86,0.00,0,-0.7" PX4_GZ_MODEL=x500_depth ./build/px4_sitl_default/bin/px4)

Would you please guide me to solve my problem? Thanks in advance

This is my Error:
desktop:~/PX4-Autopilot$ cd /PX4-Autopilot
desktop:/PX4-Autopilot$ PX4_SYS_AUTOSTART=4002 PX4_GZ_MODEL_POSE="268.08,-128.22,3.86,0.00,0,-0.7" PX4_GZ_MODEL=x500_depth ./build/px4_sitl_default/bin/px4

Thanks for prompt reply, my system is Ubuntu 22.4.
since I use Ubuntu, in your opinion, what is the problem?

May I ask you to have your email, or connect to my email (mojgan.rezakhani8683@gmail.com)

@Mojgan-arch Check your inbox. In the meantime check if your model path is set correctly and there is access to the drone model. Check "Additional Configs" in readme.
