How to use MVNC_DEBUGINFO or MVNC_DEBUG_INFO

idata — Thu, 04 Jan 2018 03:53:59 GMT

I got an error of MVNC_MYRIAD_ERROR when trying to call mvncGetResult(). Basically, I was running the run.cpp apps in GoogLeNet folder using my own graph file. The graph file is loaded successfully, but I eventually get an error. when trying to debug more to see what error is, I got:

pdo1@degcoeng001:~/workspace/ncsdk/examples/caffe/GoogLeNet/cpp$ ./run_cpp

Successfully opened NCS device!

Successfully allocated graph for ../graph

Successfully loaded the tensor for image ../../../data/images/nps_electric_guitar.png

An error has been reported by Intel® Movidius\u2122 VPU. Use MVNC_DEBUGINFO to get more information

I wonder if anyone has tried to use MVNC_DEBUGINFO or MVNC_DEBUG_INFO (because MVNC_DEBUGINFO is deprecated), and give me some example to see more detail about my error.

Thanks in advance for your help

@phong.do@intel.com After receiving an MYRIAD_ERROR message, you can read MVNC_DEBUG_INFO for more information about the error you encountered.

I got debug info using this code:

if (ncsCode == MVNC_MYRIAD_ERROR)
{
char* err;
unsigned int len;
mvncGetGraphOption(ncsGraph, MVNC_DEBUG_INFO, (void*)&err, &len);
cout<<string(err, len)<<endl;
}
