OpenCV with Yolo v3 failed to load on MYRIAD

[SC_Huang]

we're using OpenCV in OpenVINO on Windows10 , with i7 CPU/GPU, NCS2 and acceleration card

Loading the Yolov3 network with CPU

net.setPreferableBackend(DNN_BACKEND_INFERENCE_ENGINE);
net.setPreferableTarget(DNN_TARGET_CPU);

And GPU/OpenCL

net.setPreferableBackend(DNN_BACKEND_INFERENCE_ENGINE);
net.setPreferableTarget(DNN_TARGET_OPENCL);

Works fine,

BUT when the condidtion in MYRIAD...

net.setPreferableBackend(DNN_BACKEND_INFERENCE_ENGINE);
net.setPreferableTarget(DNN_TARGET_MYRIAD);

We got error message

But My MYRIAD device does work on demo application in OpenVINO,

Why we got this error?

Dear SC,

you say "NCS2 and acceleration card". Can you kindly be more specific ?

Which acceleration card are you using ?

Thanks for using OpenVino !

Hi Shubha,

We have two platform, one with a NCS2 and the other with a Mustang-V100-MX8 card.

Both appear the same problem.

[SC_Huang]

Update to OpenVINO v2019.1.087

MYRIAD DO work now!

But DNN_TARGET_CPU and DNN_TARGET_OPENCL_FP16 canNOT work now...

[Shubha_R_Intel]

Dear SC Huang,

thanks for the update. I don't understand however. Are you trying to set DNN_TARGET_CPU for execution on the Mustang-V100-MX8 card ? Are you trying to set DNN_TARGET_OPENCL_FP16  for execution on the Mustang card also ? Can you kindly give me more details ?

Thanks,

Shubha

Is there any solution of this? I am not able to run Tiny Yolov3 on NCS using OpenCV dnn.
