Skeleton Tracking: Internal Error Occured. Application will now close. Error Details: "Couldn't resolve requests"

[meschi89]

Required Info
Camera Model	{ D435}
Firmware Version	(Open RealSense Viewer --> 2.42.0.2845)
Operating System & Version	{Win 10
Platform	PC
SDK Version	{ legacy / 2.. }
Language	{C or C++ }

Issue Description

I have installed the IntelRealSense Viewer and everything looks as it is working.
Then I installed the Skeleton Tracking SDK, entered my trial key and wanted to start the example .exe

When I start the /bin/csharp-interactive.exe and click the play button, it shows the message "Internal Error Occured. Application will now close.
Error Details: "Couldn't resolve requests""
The application closes afterwards automatically.

When i start the "bin/cpp-realsense.exe" I get something similar:
"Exception encountered starting the RealSense pipeline: Couldn't resolve requests"

To just want to test the SDK, this first impression with a bug is awful and represents the quality of the Skeleton Tracking SDK. Please fix.

The bin/csharp-image.exe returns the following output:

Skeleton tracking will be run on an image saved at %LOCALAPPDATA%\res\images\skeleton_estimation.jpg...

Hi @meschi89 My understanding from your description is that the Cubemos Skeleton Tracking SDK example program csharp-interactive.exe did not work on your computer but the bin/csharp-image.exe did work for you. Is that correct please?

The Cubemos Skeleton Tracking SDK is not an Intel product and technical support for it is provided by the Cubemos company. They can be contacted at the link below.

https://www.cubemos.com/skeleton-tracking-sdk

The Cubemos SDK is a separate software from the RealSense SDK and its RealSense Viewer program, which Intel does provide technical support for.

Hello MartyG

The csharp-image.exe results a skeleton with 18joints within the image "skeleton_estimation.jpg" (the example image) -> correct

the csharp-interactive shows (see screenshot, stops after dialog approval) -> not good

The csharp-realsense shows
Initializing console Skeleton Tracking sample with RealSense ...
Hold the Intel RealSense with person(s) in scene and hit ...

Unhandled Exception: System.Exception: Couldn't resolve requests ---> System.Runtime.InteropServices.ExternalException: rs2_pipeline_start_with_config(pipe:0000024ACE9B5450, config:0000024ACE9B5770)

I hope that this gives some insights

Intel does not provide technical support for the Cubemos SDK so we cannot offer advice about your problem with it. Please provide your image and results to Cubemos. Thanks!

[meschi89]

Ok, I will contact them. Thanks for your help.
The Intel RealSense Viewer 2.42.0 works as expected.

However, in comparison to the 'Azure Kinect' the 'RealSense D435' stands no chance.
Thanks for your help.
