Weird bug

I just start using Isaac-gym, and I follow the install guidance. But why I try to run example, it show 65837 segmentation fault (core dumped)
I check dependencies, list as follows


I write a very simple program to show the bug (it is due to create_sim)

from isaacgym import gymapi

gym = gymapi.acquire_gym()
sim_params = gymapi.SimParams()
sim_params.physx.use_gpu = True
try:
    sim = gym.create_sim(0, 0, gymapi.SIM_PHYSX, sim_params)
except:
    print("except")

print("done")

The output is


Importing module 'gym_38'

create_sim Doesn’t success and throw core dumped. Anyone know why? Or have any advice? Thank a lot!

I find out, it maybe because Isaac gym can’t find CUDA device, I am using RTX3090 and it tell me out of memory While using 0% memory. So I guess, Isaac gym doesn’t find graph card.


I will try to debug create_sim and test if Isaac gym recognizes GPU or not. Any advice will be helpful!

OK, for anyone facing the same problem, it is due to driver version!
The document said 470 and greater, and I use 495, BUT! Actually 510 worked!
The working config is:
CUDA 11.3
Driver 510.60.02
PyTorch 1.10.0
