If I set no_camera=True, self.gym.create_sim will success but the system still will fail because of could not find camera with handle

I'm deployed to run within a container. When I connect to the container via SSH and execute the command python legged_gym/scripts/train.py --headless --task go2_distill, like you, I encounter a segmentation fault. However, when I connect to the container using TurboVNC and execute the command, there is no error.

i guess graphic interface is needed, the program will fail on ssh or virtual machine
