strange behavior of separable convolution in inference engine


I built my custom model with tensorflow and converted it to IR.

and when I tested, the output of the model changed sometimes.

I took several experiments and found out that a certain 'separable convolution' layer does not return same output even with same input


Is there anyone help me to resolve this issue?


I attached the converted model I used.

I made that separable convolution layer as output.



* I used openvino_2019.3.376, myriad stick 2

Hi msong17,


Thank you for reaching out.

Could you please answer the following questions:


  • Which framework and topology is your model based on?
  • What was the Model Optimizer command used to convert to IR format?
  • Could you provide us the IR files and the frozen model?
  • How are you testing your model, are you using our sample codes?
  • Could you provide a sample input and expected output?
