Illegal instruction (core dumped), when run segmentation_demo.py with FP16-INT8 semantic-segmentation-adas

It's OK when run segmentation_demo.py  with FP16 or FP32. However the FP16-INT8 occurs the core dumped error.

Maybe it is a problem of the instruction set, as another computer with intel core works fine with  FP16-INT8.

Other demos also works fine with  FP16-INT8. Maybe there are some special layers that not compatible with  Celeron Processor?

 

OS: Ubuntu 18.04

Openvino version: 2020.2

CPU:  Intel 8th Gen Celeron Processor N4100

As you have mentioned, this seems to be an issue with device support for the INT8 Model Format.

Could you please answer the following?

  • Are you using the semantic-segmentation-adas-0001 model?
  • Are you able to run the FP16-INT8 Model using benchmark tool on the Celeron Processor?
  • Are you able to use any other FP16-INT8 Model on the Celeron Processor?

Of course.

1. Yes.

2. Not tested.

3. Yes, I've tried with face recognition python demo with FP16-INT8 Model and it works well.
