OpenVX sample program crashed with illegal instruction

[md_danish_a_]

I have installed Intel Computer Vision SDK, to use ModelOptimizer with caffe from here. Installation was successful and using ModelOptimizer, OpenVX code was generated along with normalized weights. From the generated code main.c was compiled successfully along with its dependencies. When i am running the generated binary its showing illegal instruction.

<code>Program received signal SIGILL, Illegal instruction.

Hi, 

Did you install all prerequisites from this guide- https://software.intel.com/en-us/cvsdk-quickstartguide-installing-intel-computer-vision-sdk

Hi Stav S

Thanks for the response, My machine is Intel(R) Core(TM) i7-3720QM CPU @ 2.60GHz, which is i7-3rd generation core processor with Intel® HD Graphics 4000. And in the link you have shared, Its mentioned that supported and validated platforms are Intel 6th generation machines. Is it possible to use model optimizer on this machine, using any older SDK revisions.

Like I was able to use Media Server SDK on this Machine using R2 version, other versions were not compatible with this machine.

Thanks,

Danish

Hi Danish,

I'm afraid CV SDK is a newer product and there for there is not version supporting 3rd generation core processors.
