I have a Windows 10 laptop that I build an application that runs OpenVino inference engine. However, when I move this application to a Windows 10 tablet the application crashes straight away. I have narrowed this down to cpu_extension.dll. If I use the DLL of openVino built on the tablet itself, it is fine.
Is there a way to create the cpu_extension.dll on my laptop such that it is portable to the tablet?
Does your Windows 10 tablet run ARM or Intel X86 ? OpenVino is not supported on all Intel processors. There is also a GPU dependency.
Please read this:
I understand. If you study the source code that goes into building cpu_extensions.dll, the answer to your question can be found in C:\Program Files (x86)\IntelSWTools\openvino_2019.1.087\deployment_tools\inference_engine\src\extension\cmake\CPUID.cmake . Reading the CPUID plays a role in building cpu_extensions.dll . So if you build that DLL on your laptop, there is no way it can work on your tablet, unless you modify that file somehow (which I don't suggest).
To experiment with such things, I'd rather you go for the dldt github:
I'm sure it's possible to build on the laptop and transfer the cpu_extensions.dll onto your tablet, but you'd have to hardcode stuff which the CPUID command automatically returns.
Hope it helps
Thanks for using OpenVino
I guess that your tablet is using Intel ATOM processor which supports SSE instruction set only, while your desktop computer is using modern CPU which supports AVX2 instruction set / AVX512 instruction set. In my computer, the file name of the CPU extension is "cpu_extension_avx2.dll" which suggests that the DLL file is for processors supporting AVX2 instruction set. How's yours?
