[Error] [carb.gym.plugin] cudaImportExternalMemory failed on rgbImage buffer with error 999

Hello, when I run the distillation policy, this error was returned, while everything goes fine during base policy training. Does anyone know how to solve this? Thanks a lot!
I know that it might be the problem of ubuntu version, is there any solution not to downgrade system?QAQ

command: python train.py --exptid 111-11 --resume --resumeid 000-00 --delay --use_camera --no_wandb

I fixed it with downgrade my ubuntu22.04 to 20.04. Seems the only way to fix it.

add this in your code or export the environment
os.environ['VK_ICD_FILENAMES'] ='/usr/share/vulkan/icd.d/nvidia_icd.json'

it works for me ubuntu22.04 conda python3.8
