The NCS2 produces totally different results compared to nVidia GeFore GTX 1060 from the beginning

Hi Guys in Intel,

I just wanted to find out the reason NCS2 does not produce same outputs as expected, and made a simple experiment.

I created a very simple IR model which contains only one layer, like this( I also attach the model)

<?xml version="1.0" ?>
<net batch="1" name="areca" version="4">
  <layers>
    <layer id="0" name="inputs" precision="FP16" type="Input">
        <output>
          <port id = "0">
            <dim>1</dim>
            <dim>3</dim>
            <dim>416</dim>
            <dim>416</dim>
          </port>
        </output>
    </layer>
    <layer id="1" name="layer01.convolution" precision="FP16" type="Convolution">
      <data auto_pad="same_upper" dilations="1,1" group="1" kernel="3,3" output="16" pads_begin="1,1" pads_end="1,1" strides="1,1"/>
      <input>
        <port id="0">
          <dim>1</dim>
          <dim>3</dim>
          <dim>416</dim>
          <dim>416</dim>
        </port>
      </input>
      <output>
        <port id="3">
          <dim>1</dim>
          <dim>16</dim>
          <dim>416</dim>
          <dim>416</dim>
        </port>
      </output>
      <blobs>
        <weights offset="0"  size="864" />
        <biases offset="864"  size="32" />
      </blobs>
    </layer> 
  </layers>
  <edges>
    <edge from-layer="0" from-port="0" to-layer="1" to-port="0"/> 
  </edges>
  <meta_data>
  </meta_data>
</net>

and load image data from input.bin (in the attachment), the NCS produce totally different results compared to that I produce in nVidia GeForce 1060( with datatype FP16), as below:

This also leads to a totally different detection result on GPU

I also attach the visual studio 2015 project and the source file for your reference.

Please help me to fix this problem, many thanks.

Dear Tsin, Ross,

Can you kindly try the OpenVino Python Sample object_detection_demo_yolov3_async on this image ? That sample accepts images for -i . Please let me know what happens.

Thanks,

Shubha
