No demo tracking; "Cannot load ... NuitrackModuleGPU.dll"

1

I’ve just installed trial and run demo. I see it using azure properly, but no skeleton etc (as in Can I get a code demo like Nuitrack pro)

If I switch the demo to AI mode the tracking does display.

When I run nuitrack_sample from the command line I see the message “Cannot load library module: D:\Program Files\Nuitrack\nuitrack\nuitrack/middleware/NuitrackModuleGPU.dll”. This is presumably the reason behind the failure in the demo.

From Cannot load NuitrackModuleGPU.dll I see CUDA/CUDNN may be needed; though this doesn’t seem to be mentioned anywhere in install instructions. I’ve installed recent versions of these but that does not help.

Windows 10; 1080 GPU, Nvidia 555.85 drivers, Nuitrack 0.37.20, CUDA_9.0.176, CUDNN 9.1

Any idea how to get the classic tracking working?

Hi @stodd,

Sorry for the delayed reply.
Is this issue still relevant to you?

Do you have this problem with the latest version of Nuitrack?

Cannot load library module: D:\Program Files\Nuitrack\nuitrack\nuitrack/middleware/NuitrackModuleGPU.dll

Actually, this warning was only related to the Object Detection feature and did not affect Skeleton Tracking.

Looking forward to your response.

Thanks for getting back to me.
No, I haven’t been trying it. Though as I see the new version I’ll give it another test to see if it could be useful for us.

Small update. I’ve installed the newer version and the demo works correctly for both Classic and AI.
I don’t think we will be wanting to use it in longer term as our projects have moved on anyway,
but will remember it in case we do want to revisit.
Greetings
Stephen
