The recall rate of tiny-yolov3 with trt5 is lower than darknet

Description

The tiny-yolov3 is trained by darknet,and I get the tensorrt engine by tensorrt c++ api, the precision is kfloat.
I test the tensorrt engine of tiny-yolov3 with 500 pictures,the engine can find 1864 objects.
However, I can get 2121 objects by runing darknet with the same picture.
How can I optimizate the engine?
Thanks.

Environment
