Internal Error in NVIDIA AI Denoiser

[acrobaticpoly]

Just got this message -
Error encountered during denoising.
Unknown error (Details: Function "_rtCommandListExecute" caught exception: Failed to launch DLDenoiser post-processing stage. DLDenoiser run method failed with error -29.)   

Scene is just a sphere with a HDRI .

Cheers and apologies if I've posted this in the wrong part of the forum.

What GPU are you using? First thing to check is that all NVIDIA drivers are up to date.

Thanks Guys,

I've just got another one:

Unknown error (Details: Function "_rtCommandListExecute" caught exception: Assertion failed: "!m_launching : Memory manager launch is already active", file: C:\u\workspace\rel5.1-win64-cuda90-VS2015-build-Release\sw\wsapps\raytracing\rtsdk\rel5.1\src\Memory\MemoryManager.cpp, line: 962)   

I'll take a look at some of the solutions.

I'll let you know if what you've suggested works.

Thanks again.

Looks like a problem with your current driver.
What is your exact GPU model, and do you have only one GPU installed in your computer?
