RPI interactive face demo help R1 2019

Jump to solution

Hello,

I'm trying to use all of the options on the interactive face demo. Maybe i'm not executing them correctly. When I just use the face models I get the correct output:

pi@raspberrypi:~/Downloads/inference_engine_vpu_arm/inference_engine/samples/build/armv7l/Release $ ./interactive_face_detection_demo -i ~/Videos/inputVideo.mp4 -m /home/pi/Downloads/face-detection-adas-0001.xml -no_show -d MYRIAD
InferenceEngine:

But when I run the software with a -m_hp flag I get the following error:

pi@raspberrypi:~/Downloads/inference_engine_vpu_arm/inference_engine/samples/build/armv7l/Release $ ./interactive_face_detection_demo -i ~/Videos/inputVideo.mp4 -m /home/pi/Downloads/face-detection-adas-0001.xml -m_hp ~/Downloads/head-pose-estimation-adas-0001.xml -no_show -d MYRIAD

[ INFO ] FLAGS_d= MYRIAD
[ INFO ] Loading plugin CPU
[ ERROR ] Cannot find plugin to use :

I've added some debug points along the way. for some reason I don't get past this point: [ INFO ] made it to here 1.5 MYRIAD. Since i'm working remotely at the moment I don't have a good way to debug so any help would be appreciated and welcome.

Thanks,

~Shane

The log says

> Loading plugin CPU

That means it tries to load Head Pose Estimation model to CPU plugin. There is no CPU plugin in Raspberry Pi version of OpenVINO so you need to add an extra command line argument -d_hp MYRIAD.
