Invalid device ID (0)

Hi,

I am trying to run a demo on a headless RTX3090 server and I meet this error when building the Visualizer. The log is as below [Genesis] [06:00:53] [INFO] ╭─────────────────────────────────────────────────────────────────────────────────────╮ [Genesis] [06:00:53] [INFO] │┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉ Genesis ┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉┈┉│ [Genesis] [06:00:53] [INFO] ╰─────────────────────────────────────────────────────────────────────────────────────╯ [Genesis] [06:00:54] [INFO] Running on [NVIDIA GeForce RTX 3090] with backend gs.cuda.

and my code is ` import genesis as gs from genesis.constants import backend as gs_backend

gs.init(backend=gs_backend.gpu)

scene = gs.Scene( show_viewer=False, # Disable viewer since we're recording )

plane = scene.add_entity(gs.morphs.Plane()) franka = scene.add_entity( gs.morphs.MJCF(file='xml/franka_emika_panda/panda.xml'), )

cam = scene.add_camera( res=(320, 240), pos=(3.5, 0.0, 2.5), lookat=(0, 0, 0.5), fov=30, GUI=False )

scene.build()

cam.start_recording()

for i in range(5): # Reduced from 1000 to 100 frames scene.step() # Render only every 2nd frame to improve performance if i % 2 == 0: cam.render()

cam.stop_recording(save_to_filename='simulation.mp4', fps=30)`
