Trouble with ComputeOnDesktopYolo

[VictoriaNavarrete]

Thank you so much for this repository. It is very useful for me, so that I am developing an object detection app on the Hololens2.

I have no trouble building the YoloHololensUnityProject, but ComputeonDesktopYolo is not working properly for me. When I introduce the IP direction of my Hololens by release in x64 at Local Machine, I get an error at ppltasks.h "Unhandled exception at 0x00007FFA15A9B65C (KernelBase.dll) in ComputeOnDesktopYolo.exe: 0xC000027B: An internal application exception occurred (parameters: 0x0000029E3DB94FE0, 0x0000000000000001)."
I tried deactivaitng the firewall and the proxy but did not work.

Previous to this point, I had to chage MainPage.xaml.cpp an delete the concurrency from this void, and ad #pragma

"
#pragma warning(disable:4716)
concurrency::task MainPage::LoadModelAsync()
{
// just load the model one time.
if (_model == nullptr)
{
std::wstringstream wStringstream;
wStringstream << "Loading model..." << "\n";
OutputDebugString(wStringstream.str().c_str());

		try
		{
			String^ filePath = "ms-appx:///Assets/" + modelFileName;

			// From Windows ML samples, MNIST cpp
			create_task(StorageFile::GetFileFromApplicationUriAsync(
				ref new Uri(filePath)))
				.then([](StorageFile^ modelFile) {
				return create_task(YoloModelIO::Model::CreateFromStreamAsync(
					modelFile,
					LearningModelDeviceKind::Default)); })
				.then([this](YoloModelIO::Model ^model) {
					this->_model = model;
				});
		}
		catch (const std::exception&)
		{
			std::wstringstream wStringstream2;
			wStringstream2 << "Error loading the model." << "\n";
			OutputDebugString(wStringstream2.str().c_str());
			_model = nullptr;
		}
	}
#pragma warning(default:4716)
}

I need urgent help for this issue, I would be very grateful. I attached a capture of how far I could get with ComputeonDesktopYolo

Hi, I have the same issue too,
it said: “ComputeOnDesktopYolo::MainPage::LoadModelAsync”: should return a value
did anyone know how to solve it?

I have abandoned this a loooong time ago. I suggest writing a simple socket Server in Python or whatever that takes an encoded png and returns the yolo output. That’s what I did. I don’t have the code anymore unfortunately. But it was relatively easy to write. And then try to reuse the HoloLens code from this project.
