Hi Edwin,

I believe the issue is due to the frame/image not loading properly. Could you try running the sample with an image instead of the camera feed?

~/sample_release/intel64/Release$ ./interactive_face_detection_demo -i <PATH to IMAGE> -m /home/asrock/sample_release/intel_model/face-detection-0004/FP16/face-detection-retail-0004.xml -d MYRIAD

Could you share additional information about the camera you are using? Are you able to open the camera feed using any application on Ubuntu?

Regards,

Jesus

Dear Hung, Edwin,

Please read the Interactive Face Detection Demo Documentation . You are not running the demo properly. You are missing several switches such as -m_ag -m_hp -m_em -m_lm...If you pass in all the required arguments, the demo should work fine.

Thanks,

Shubha

Hi Edwin,

It looks like you are running the demo correct as the -i and -m are the only required parameters, everything else should be optional. I am not able to replicate your issue. Please make sure you are following all the steps on the getting started guide the Intel NCS 2. I recommend uninstalling and reinstalling OpenVINO to ensure everything is installed properly. Try running the demo mentioned in the getting started guide. 

cd ~/intel/openvino/deployment_tools/demo
./demo_squeezenet_download_convert_run.sh -d MYRIAD

Regards,

Jesus

Hi Edwin,

It looks like you are running the demo correctly as the -m and -i are the only required parameters, all others are optional. I was able to run the demo with both an image and from the camera without any issues. Could you try to uninstall and re-install the OpenVINO toolkit? Please follow all the steps listed on the Get Started Guide for the Intel NCS 2.
