Nvidia Background | Failed to load feature

Windows 11 x64bit machine.
RTX4090 GPU
TD version: 2022.29850 & 28040

Nvidia Background TOP not functioning. Loads SDK 0.6.4 from Nvidia

Error: Failed to load feature: There was a problem deserializing the inference runtime engine (/project1/nvbackground1)

-I suspect this to be a conflict with the latest SDK for 4xxx series GPUs not retro-supported to 0.6.4
(this error is also produced with the denoise TOP as well)

Ive run into the same issue. Did you figure out a fix / solve?

I learned that the RTX4xxx series GPUs use a different AI model - thus making the nvidiabackgroundTOP, denoiseTOP, and facetrack operators unusable. There is currently no solve, and there is no roadmap to include functionality.

A solution would include waiting for derivative to update their software to reflect use of the new GPUs. Alternatively, RTX2xxx and RTX3xxx series cards will work.

I’m having this exact issue. Anyone find a solution yet?

I’m running into the same issue, new show machine is a 4090 laptop and this pretty much renders all my Notch IMAG blocks useless on the current machine as I use TouchDesigner as the media server. Looks like it is still borked after the latest release too.

Yeah, unfortunately the Nvidia library in the current release does not support the 40xx series cards. We have tested the update internally, but it breaks some other systems that still rely on the older shared CUDA/cuDNN libraries. We are still working on a solution and will hopefully be able to let you guys know something soon.

Great! I was just about to post this! Recently upgraded to a 4090 but now missing that awesome functionality :sob:
