On RPI4B Raspian Buster, Openvino 2019 R.3.1, NCS2 I am getting this error:

Hi Pih,

Thanks for reaching out.

You need to replace the input flag: "-i ./person-detection-retail-0002.bin" with the full path of the input image. For example:

./object_detection_sample_ssd -i <path_to_image>/inputImage.jpg -m <path_to_model>person-detection-retail-0002.xml -d MYRIAD

Please refer to the Object Detection Sample SSD to review the structure and flags in the command.

Feel free to ask if you have any other questions.

Regards,

Randall B.

@yamen  And you also use OpenVINO 2019 R3 version, which is pretty old? Is it possible for you to upgrade to the latest version, that to the moment is 2021.4.1 ?
