Fix script of Azure Kinect Body Tracking SDK sample program for Unity

[UnaNancyOwen]

This pull request will change the following two things.
It will allow the sample program to work correctly.

• Change TrackerProcessingMode To Cuda
  This project currently only works with CUDA execution provider.
  Azure Kinect Body Tracking SDK default processing mode (Gpu) is changed to DirectML execution provider.
  Therefor, It is nessesary to specify CUDA execution provider explicitly in this project.

• Fix Copy Dependencies
  Fix file name cudnn_cnn_infer64_8.dll and cudnn_ops_infer64_8.dll.
  Add missing file cufft64_110.dll.

Hi! We should do the instalation before or after the branch pull?
Instructions -> (https://github.com/microsoft/Azure-Kinect-Samples/tree/master/body-tracking-samples/sample_unity_bodytracking)

I cannot confirm that GPU mode does not work (after copying a lot of dependencies both in Plugins and project root folder).

Hi guys, i am not experienced in using git but maybe you could help me out please?
Im experiencing the same issue:
"catching exception for background thread result = K4A_RESULT_FAILED UnityEngine.Debug:Log(Object)"

Im relatively unexperienced in using git and i could spend a day trying to figure this out (i use git bash btw) but im just gonna give it a shot asking the right question:

From what i understand i should use a pull request: '""This pull request will change the following two things."

I do understand how to clone to my local desktop.

1. Is pulling cloning? Im asking because i found the following picture:

2. Will this pull request edit the existing file i cloned from: https://github.com/microsoft/Azure-Kinect-Samples.git or replace it for instance?

3.What should i enter as a reference adress to pull from? And what will i pull?

thank you

A pull request simplified is a change someone is proposing and requesting it to be merged eventually if approved.

The naming is weird when coming from a non-GitHub world. It is not you pulling what you need.

Thank you, i am starting to understand more of this topic.

So.. im gonna delete the local repository and just clone this(https://github.com/UnaNancyOwen/Azure-Kinect-Samples.git) one onto my local machine: edit <- Well, that does not work.. i have the same error: "catching exception for background thread result = K4A_RESULT_FAILED UnityEngine.Debug:Log(Object)"

So what im guessing is that UnaNacyOwen's repo does not have the changes found here() since the SkeletalTrackingProvider script still has the same TrackerProcessingMode.Gpu while i have read it should be cuda.

This should mean that the repository above which i cloned does not have the changes found here(#62). So i am trying to find a way to get those changes in my project.

I think i have 2 options(can anyone confirm, am i on the correct path?):

1. Merge these(ef9f8e4, 115f27b, 984a95f) 3 commits with my local repo cloned from ((https://github.com/UnaNancyOwen/Azure-Kinect-Samples.git))?

2. Do the changes in these 3 commits(ef9f8e4, 115f27b, 984a95f) manually?

I did all the changes by hand and its all working by now but thanks i will start to learn more on how to use github and start to do this stuff like i supposed to.

it seems(im not sure) you have the same error message as i had..

To fix it i i used these 3 commits(ef9f8e4, 115f27b, 984a95f) and incorporated them manually.

Maybe the git checkout fix_script did not work correctly?

Yes, after I checkout your fix_script, the exception is still there.

I can confirm that, with only these changes, and using Azure Kinect Body Tracking SDK 1.1.0 (not 1.1.1) and Unity 2020.3.9 , body tracking works (with TrackerProcessingMode.Cuda).

[MoritzSkowronski]

I cannot confirm this, as I am getting the same K4A error as ever. Tried it using different Unity versions (2019.1.2f1 and 2020.3.32f1) and different Body Tracking SDKs (1.1.1, 1.1.0, 1.0.1)

[leventalpsal]

Have you :
installed sensor SDK too,
run the NuGet Package Manager-> Package Manager Console -> Update-Package -reinstall
apply these changes, then run the MoveLibraryFile.bat ?

[MoritzSkowronski]

I've figured it out: I did not use a device with a NVIDIA GPU, so this is why CUDA probably did not work ;)

Testet it now on a RTX 3070 machine and works fine!
