Hi,

The error indicates some compatibility issue.
Did you launch the YOLOv3 engine that built on same environment?

Please noticed that TensorRT engine is not portable.
The engine file is quite sensitive to library version and deploy platform.

Thanks.

Hi,

Yes engine going to in the same environment.
