Object detection not working

[esbennn]

Hi,
I'm trying to get Object detection working for a project.
The camera is a Realsens D435 and the platform is windows 10.
With the nuitrack activation tool, I have activated an AI license for the camera, and the test samples work - unless I check the "AI: Object Detecion", then it opens a window and immediately closes it again, with the following message in the box:

Starting test...
    3D sensor serial number: 215322076948
    3D sensor provider name: Realsense2DepthProvider
ERROR: Sample failed. Exit code: 3

Unckecking the AI: Object Detection box, it works as expected

As detailed in the online docs, I have installed Cuda 9

C:\Users\Playground>nvcc --version
nvcc: NVIDIA (R) Cuda compiler driver
Copyright (c) 2005-2017 NVIDIA Corporation
Built on Fri_Sep__1_21:08:32_Central_Daylight_Time_2017
Cuda compilation tools, release 9.0, V9.0.176

The PC has a NVIDIA GeForce RTX 2060 with latest drivers installed.

I have tried installing an older version of Nuitrack (v0.35), with the same results. I intended to install v0.34, as that is th version used in the video above, but executables for older versions are not available.

Any ideas?

Hi @esbennn,

Please try to execute the application by path: %NUITRACK_HOME%\bin\nuitrack_sample.exe from cmd and send us the output.

The NuitrackModuleGPU.dll seems to exist at the specified location:

Okay, after trying out on a different machine (linux), I managed to install the (ancient versions of ) cuda and associated cdnn files. This worked.
I then tried reinstalling everything on the windows machine, and it worked. Maybe the cdnn files were somehow corrupted on download the first time.
