I'm working on facenet with openvino R3 and R4 release. I converted two one model (20180402-114759) to test, but when I use the following code to load the model (using Load Network() debug mode) I got internal ie_exception "Unknown exception". And when I continue to debug, it will jump into the LoadNetwork() "if (ret.get() == nullptr) THROW_IE_EXCEPTION << "Internal error: pointer to executable network is null";".
I want to know what is wrong with my code or do I foget something else?
code:
int FaceRecognitionClass::initialize(std::string modelfile){
InferenceEngine::PluginDispatcher dispatcher({""});
//InferencePlugin plugin(dispatcher.getPluginByDevice("CPU"));
#if 1
plugin=dispatcher.getPluginByDevice("CPU");
#else
plugin = dispatcher.getPluginByDevice("GPU");
#endif
cout<< "============Initialize FaceRecognition ================="<<endl;
try {
networkReader.ReadNetwork(modelfile);
}
catch (InferenceEngineException ex) {
cerr << "Failed to load network: " << endl;
return 1;
}
cout << "Network loaded." << endl;
auto pos=modelfile.rfind('.');
if (pos !=string::npos) {
string binFileName=modelfile.substr(0,pos)+".bin";
std::cout<<"binFileName="<<binFileName<<std::endl;
networkReader.ReadWeights(binFileName.c_str());
}
else {
cerr << "Failed to load weights: " << endl;
return 1;
}
auto network = networkReader.getNetwork();
// --------------------
// Set batch size
// --------------------
networkReader.getNetwork().setBatchSize(1);
size_t batchSize = network.getBatchSize();
cout << "Batch size = " << batchSize << endl;
//----------------------------------------------------------------------------
// Inference engine input setup
//----------------------------------------------------------------------------
cout << "Setting-up input, output blobs..." << endl;
// ---------------
// set input configuration

//InferenceEngine::InputsDataMap input_info(network.getInputsInfo());
input_info=network.getInputsInfo();
InferenceEngine::SizeVector inputDims;
plugin.AddExtension(std::make_shared<Extensions::Cpu::CpuExtensions>());
if (input_info.size() != 1) {
cout << "This sample accepts networks having only one input." << endl;
return 1;
}
for (auto &item : input_info) {
auto input_data = item.second;
input_data->setPrecision(Precision::FP32);
input_data->setLayout(Layout::NCHW);
inputDims=input_data->getDims();
}
cout << "inputDims=";
for (int i=0; i<inputDims.size(); i++) {
cout << (int)inputDims << " ";
}
cout << endl;
const int infer_width=inputDims[0];
const int infer_height=inputDims[1];
const int num_channels=inputDims[2];
const int channel_size=infer_width*infer_height;
const int full_image_size=channel_size*num_channels;
/** Get information about topology outputs **/
output_info=network.getOutputsInfo();
InferenceEngine::SizeVector outputDims;
for (auto &item : output_info) {
auto output_data = item.second;
output_data->setPrecision(Precision::FP32);
output_data->setLayout(Layout::NCHW);
outputDims=output_data->getDims();
}
cout << "outputDims=";
for (int i=0; i<outputDims.size(); i++) {
cout << (int)outputDims << " ";
}
cout << endl;
//const int output_data_size=outputDims[1]*outputDims[2]*outputDims[3];
// --------------------------------------------------------------------------
// Load model into plugin
// --------------------------------------------------------------------------
cout << "Loading model to plugin..." << endl;
std::map<std::string, std::string> config;
config[PluginConfigParams::KEY_DYN_BATCH_ENABLED] = PluginConfigParams::YES;
executable_network = plugin.LoadNetwork(network, config);
