Unexpected layout error Myriad VPU compute Stick 2

Hello,

I have an issue when i'm using my model on Myriad neural compute stick 2. 

My model has 2 inputs : [1 128 1] and [1 8]

With the benchmark_app I can change the batch size by adding the following option :

-shape "inputs_cnn:0[2,128,1],inputs2:0[2,8]" (for size batch=2)

On CPU it works with no problem but when i launch it on the Myriad stick (-d MYRIAD) an error appears:

Do you know where it come from ?

 

Best regards,

Hi Victor Martin,

Thank you for reaching out. Based on your error, the main reason might be due to supported output layout.

Please have a try with using 4 dimensions (NCHW).

 

You can refer following link under supported output layout:

https://docs.openvinotoolkit.org/latest/openvino_docs_IE_DG_supported_plugins_Supported_Devices.html

 

In addition, you can also use the option of -b BATCH_SIZE to change the batch size:
