DS4.0.2 TX2 : precision detection decreased after update yoloV3 model

Hello,
I updated yolov3 model based on DS4.0.2 ,and modified yolo parse code, then tensorRT could parse the net successfully ,but the precision detection decreased a lot, I double check the yolo parse code and all the config file ,not found any problem.

I updated yolov3 model network according yoloV3-spp and Slim yoloV3 ,both decreased a lot of precision detection.

I have created this topic last year ,but didn’t solved until now, for detail please see

Environment

Jetpack 4.2.2
TX2
DS4.0.2
project based on objectDetector_Yolo

It’s very import for me ,I can’t sure where is the issue points.
