Crushing after deploying on windows IOT #51

Closed ZubSam closed 5 years ago

ZubSam commented 5 years ago

We have UWP application.

After adding this libs from NuGet we have a problem.

When we try to run our application in desktop (x86/64) - all works.

But when we try to run into rasbery pi 3 (windows IoT, ARM) we have an exception when we try to initailize class ObjectDetectorDescriptor

HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG)

for example: var descriptor = new ObjectDetectorDescriptor();

Hi, The ObjectDetector skill is supported for x64 only for now. We made this decision because the algorithm and machine learning model used under the hood take a lot of memory at runtime, beyond what 32-bit UWP appx permits, leading to OutOfMemory exceptions. We constrained it to x64 only until we can figure a way to gracefully scale to other architectures. That said, note that we could support other architectures for non-UWP apps not constrained with a maximum memory consumption amount. We are also tinkering with lighter and faster (though less precise) models, let us know if this is something you think we should prioritize.

Hello. Thanks for the reply, in my opinion it is very important. I think we are not the first to encounter such a problem, and in the future it will be very critical because of the growing demand for the rasbery/windows iot/uwp stack. We would be very grateful if you can solve this problem as soon as possible.

Thank you for the feedback, closing this issue now, we will try to prioritize accordingly :)
