Fail to load Optix Liabrary #3

Open ypwang61 opened 2 years ago

ypwang61 commented 2 years ago

I want to use your OptixRender program and quote your paper in the research process, but we met some problems thus we ask you for help. I used the lab server for rendering and the configuration is as follows: RTX 2080 Ubuntu 16.04 (I run program in our lab's Headless server so I'm not sure whether CAN I update the Ubuntu environment) Driver Version: 460.91.03 CUDA version: 11.2 Optix: 6.5.0 (I found that Optix 7+ don't have the liboptixu. So, Thus I can not use Optix 7.4.0 to make with optix_advanced_example) But after generating OptixRender, using the command line to run the file, I get an error message:

Terminate called after throwing an instance of 'optix::Exception' what(): Failed to load OptiX library Aborted (core dumped)

I would like to know what environment the program should be running with, and if there is anything wrong with my operation?

It seems that it can only run on Optix 5.1.1. Anything newer could produce the error.

I have the same problem in docker (ubunu18.04, cuda 10.2) but after changing the optix library version to 5.1.1 the problem was solved! thank you!

I build Optix Library successfully in docker container (FROM kunalg106/cuda102 as the author wrote in dockerfile) docker Plateform: Ubuntu 1804 Driver Version: 470.42.01 docker CUDA version: 10.2(the cuda version in the host machine is 11.4, and it was supposed to show 'CUDA Version: 10.2' but it still shows 'CUDA Version: 11.4' in docker container when using the command 'nvidia-smi'. I don't know why) Optix: 5.1.1 GPU: Tesla P100
