Replay demonstration using the raytracing rendering about maniskill HOT 5 CLOSED

Hi @shen-hhao ,

1. First make sure your Nvidia driver is correctly installed. You can check by nvidia-smi and nvcc -V
2. If your driver works well, then please check Vulkan by vulkaninfo.

nvcc -V

ERROR: [Loader Message] Code 0 : libGLX_nvidia.so.0: cannot open shared object file: No such file or directory
Cannot create Vulkan instance.
This problem is often caused by a faulty installation of the Vulkan driver or attempting to use a GPU that does not support Vulkan.

Hi @shen-hhao

As shown by the output of vulkaninfo, it seems your Vulkan driver is not correctly installed. What is your NVIDIA driver version?

Also, this command perhaps helps: sudo apt-get install mesa-vulkan-drivers

from maniskill.

NVIDIA-SMI 470.63.01 Driver Version: 470.63.01 CUDA Version: 11.4
sudo apt-get install mesa-vulkan-drivers does not work

from maniskill.

Problem solved by reinstall NVIDIA Driver with version 460.
Guess vulkan is not compatible with NVIDIA Driver Version 470.
