Segfault on from triro.ray.ray_optix import RayMeshIntersector

[XDynames]

Just trying to set this up in a project that uses trimesh to do some raycasting and I am getting a segmentation fault when importing your package.

I am using CUDA 12.3, Pytorch 2.3 with Optix 8.0.0 on ubunutu in the nvcr.io/nvidia/pytorch:24.02-py3 docker container

Can you think of anything off the bat that could be wrong or how to chase down that problem the further?
I figure it must be some sort of version conflict

Segmentation fault: address not mapped to object at address (nil)

Did some poking around in gdb it get thrown by triro.so in optixDeviceContextCreate ()

Same problem.

Sorry for the late reply. Is there more outputs form the program? And perhaps a minimal code set to reproduce the problem:)
I will try getting the docker run first so maybe let me know what GPUs are you using?

Thanks for your reply. I am using H100 Server, CUDA 12.1, Ubuntu 22.04, python 3.10.
My environment only includes python==3.10 and triro==1.3.0 (successfully installed).
When I finish the installation successfully and run 'import triro.ray', the code will only output 'Segmentation fault (core dumped)'. I run 'import triro' is OK, but run 'import triro.ray' fails :(

Than you for the feedback! I will investigate into it.

I found that I get a segmentation fault error on the A40, but not on the 4090D. Is this related to the GPU as well? I am using CUDA 11.8, PyTorch 2.1.2, and OptiX 8.0.0

I had the seg fault issue on a 4090
Maybe it’s more to do with the exact combination of drivers/dependancies at compile time?

[kangyiyang]

Yes, GPU hardware may be required to match the version of some libraries. But I'm not sure either. Maybe you can change the GPU environment and try more

I got the same problem with OptiX 8.1.0, which requires the driver version >= 555 but mine is 550. After switching to OptiX 8.0.0 (>=535) it worked fine.

[kangyiyang]

Great, I'm glad to hear that.
