[Error] Classification_sample run failure by using -d MYRIAD but -d GPU or -d CPU

[Bill_Sung]

Hi Sir,

    I use "classification_sample" to run IR of DenseNet_121 models to have failure message by use -d MYRIAD but it's good by -d GPU or -d CPU.

    My OS is Ubuntu 16.04 LTS, I think Movidius that is ready and plugged in well because message present start inference.

    Do you have saw such fail state  and have you any suggest or patch for that? Thanks.

BR

Bill

Hi Bill,

I've tried to reproduce your issue and I couldn't but I did achieve success with the NCS2 stick on Ubuntu 16.04.3 with running densenet-121 on classification sample. However, I did run it with OpenVINO R4. I highly recommend you upgrade to the latest release which is R4 and try to run the classification sample again. Let me know if that resolves the issue.

Kind Regards,

Monique Jones
