[ ERROR ] Following layers are not supported by the plugin for specified device CPU

[handyzeng]

Hi, I have a problem with the sample. Would you please help me?

OpenVINO docker,
Ubuntu 1604,
x86_64,

I followed the steps in your script.txt file to generate the *.xml and *.bin file of Yolo-v3 model,
and use python3 to run the sample in /opt/intel/openvino/inference_engine/samples/python_samples/object_detection_demo_yolov3_async
I got error as flowing:

[ ERROR ] Please try to specify cpu extensions library path in sample's command line parameters using -l or --cpu_extension command line argument

Please use CPU Extension with "-l" option.

Thanks a lot!
It works well!

Hello: I have a question as follows
Using ncs2 is no problem.
But using the CPU, the error appears as follows:

(openvino) pi@raspberrypi:~/Downloads/OpenVINO-YoloV3-master $ python openvino_tiny-yolov3_test.py -d CPU
videosFPS = 0
Traceback (most recent call last):

File "openvino_tiny-yolov3_test.py", line 164, in main_IE_infer
plugin = IEPlugin(device=args.device)
File "ie_api.pyx", line 393, in openvino.inference_engine.ie_api.IEPlugin.cinit
RuntimeError: Cannot find plugin to use :

#model_xml = "/home/pi/Desktop/openvino_out/FP16/yolov3-tiny_best.xml" #<--- MYRIAD
model_bin = os.path.splitext(model_xml)[0] + ".bin"

How do I resolve it, thank you!

@jordanlai
When using RaspberryPi (when using ARM device), only -d MYRIAD can be specified.

OpenVINO-YoloV3/openvino_tiny-yolov3_test.py

Line 44 in b5caa1c

parser.add_argument("-d", "--device", help="Specify the target device to infer on; CPU, GPU, FPGA or MYRIAD is acceptable. \

@PINTO0309 I see, thanks!
