Segmentation violation when trying to use EdgeTPU example

[timorkal]

Hi, regular examples work fine for me, but when I try to use the edgeTPU examples I am having this kind of segmentation fault.
The tensforflow version which was compiled is 2.15.0 with cmake for arm64.
edgetpu shared lib is installed through "apt-get install -y libedgetpu-dev:arm64"
Just also want to mention that python examples from the pycoral repo works fine with the tpu, so the shared lib should be fine.

EdgeTPU Version: BuildLabel(COMPILER=6.3.0 20170516,DATE=redacted,TIME=redacted), RuntimeVersion(14)

I have a same issue

[AmmarMalik93]

Any update on this issue?

[mattn]

I don't reproduce this.

[AmmarMalik93]

The reason for you not being able to reproduce is most likely is that the .tflite models in edgetpu examples are not edgetpu.tflite models but rather they are simple . tflite models. It would be good if the examples can be provided using actual edgetpu.tflite models. Even better if some examples can be provided for some of latest Yolo models like Yolov8.
