tensorRT for yolo v3 optimization failed ?

I try to use tensorRT for optimization of SSD? it success.
however, when I try to apply trt for yolov3 optimization. it failed.
my configuration is:
tensorflow 1.12
tensorRT 5
cuda 10.0
cudnn 7.3.1

tesla P4 (8G)

the error is reported as follows:
E tensorflow/contrib/tensorrt/kernels/trt_engi ne_op.cc:599] Calibration failed: Internal: Failed to build TensorRT engin e

i also use the tensorflow 18.09 container for the int8 calibration of yolov3
the error is reported as follows:

During handling of the above exception, another exception occurred:

Hello, it’d help us debug if you can share a small reproduction package that contains the source, model that demonstrates the symptoms are you seeing.

Hi, you can refer this video demonstration YOLO optim. using TensorRT.
