[Openvino] VPU HDDL plugin: RuntimeError when run example face_recognition_demo.py

[khiem_nvt]

Hello

I have installed Openvino (openvino_2021.4.752) and installed Mustang-V100-MX8 driver based on https://docs.openvino.ai/latest/openvino_docs_install_guides_installing_openvino_linux_ivad_vpu.html.

After that I verified by running scripts:
./demo_squeezenet_download_convert_run.sh -d HDDL

./demo_security_barrier_camera.sh -d HDDL

Both script worked well.

And next, I tested face_recognition_demo.py

It works well with CPU Plugin, but has error when using HDDL plugin. Log as below:
