I am very hurry ,thank you so much.

[nikos1]

Please try FP16

[nikos1]

Hello Xiaowei,

> [ ERROR ] Cannot find plugin for device: Default

The error comes from a typo - please try again without the -MYRIAD (just use -d MYRIAD)

./classification_sample -d MYRIAD -i /opt/intel/computer_vision_sdk_2018.4.420/deployment_tools/demo/../demo/car.png -m /home/liuxiaowei/openvino_models/ir/squeezenet1.1/FP32/squeezenet1.1.xml

And lease try FP16 when you generate IR or you will get this error

[ ERROR ] [VPU] Unsupported network precision : FP32

To generate FP16 IR you can add --data_type=FP16 to the model optimizer command.

Let us know if you have any issues.

Nikos

[Liu__Xiaowei]

thank you very much

[nikos1]

You are welcome!

Let us now if you see any more issues.

kind regards,

nikos

[Liu__Xiaowei]

sorry I don't quite understand，Can you tell me some detail? such as how to use FP16. because I use ./demo_squeezenet_download_convert_run.sh -d CPU also have same error

[Hyodo__Katsuya]

@Liu, Xiaowei It is as nikos says. Just execute the following. The file of FP16 is automatically generated. mistake ー＞ "-d -MYRIAD" correct ー＞ "-d MYRIAD" - When using NCS or NCS 2 or GPU ./demo_squeezenet_download_convert_run.sh -d MYRIAD - When using CPU ./demo_squeezenet_download_convert_run.sh -d CPU

[Liu__Xiaowei]

Thank you very much. The demo have completed successfully. I first use this NCS. Thank you again
