Module compilation failed

[riccardomarin]

Hi,

I am facing a new error. I do not know why, but suddenly today even with the simplest example the interpreter returns this error:

OPTIX_ERROR_INTERNAL_COMPILER_ERROR: Optix call 'optixModuleCreateFromPTX( m_context, &m_module_compile_options, &m_pipeline_compile_options, ptx.c_str(), ptx.size(), log, &sizeof_log, &mnew )' failed: c:\users\sulej\documents\visual studio 2017\projects\optix\cppsharpoptix7\modules.cpp:23)

I already tried to delete the cache and re-install the library but it still the same. Any idea on how to solve this?

Thanks again!

That one is a bit mysterious. Did you have any updates of the driver (which version is installed now)?

[riccardomarin]

RTX 2080 Ti Driver: 460.20 (27.21.14.6020), 17/09/2020

[robertsulej]

Ok, thanks. Now I have 460.15. I'll try with the newer one and let you know.

[robertsulej]

Hi Riccardo,

It seems that the issue is with the 460.20 driver. I have the same error. When I go back to 460.15 everything is OK. I'll file an issue at NVIDIA.

[robertsulej]

OK, I can confirm that the problem is with the driver. Please, switch back to 460.15 if this is possible for you. For the next release I'll update to OptiX 7.2 that was just released yesterday, maybe this will also remove the driver problem.

[robertsulej]

Closing, should be solved in the new releases.
