When I try to run python3 multiagent.py --act one_d_rpm, I meet this problem. Can you help me?

I solved this after downgrading ray[rllib] to version 1.9

In addition, I would like to ask how to rotate the viewing angle when rendering？ And why is half of the text in my GUI missing？ 2022-05-27 17-32-28 的屏幕截图

@JiahengZeng

The view that the GUI is initialized with is set in these lines: https://github.com/utiasDSL/gym-pybullet-drones/blob/4f81a89adda2a16604c441d811367f0ca8092c5d/gym_pybullet_drones/envs/BaseAviary.py#L178-L191

To move the view during the preview, look at this answer on Bullet's forums: https://pybullet.org/Bullet/phpBB3/viewtopic.php?p=41476&sid=4f0297813ba516fe2f1b18fc5f10f45c#p41476
