-## End2End Detect for TensorRT8+ and onnxruntime
-
-Usage:
-
-```shell
-# export end2end onnx for TensorRT8+ backend
-python export.py --weights yolov7-d6.pt --grid --end2end --simplify --topk-all 100 --iou-thres 0.65 --conf-thres 0.35
-
-# convert onnx to TensorRT engine
-/usr/src/tensorrt/bin/trtexec --onnx=yolov7-d6.onnx --saveEngine=yolov7-d6.engine --fp16
-
-# export end2end onnx for onnxruntime backend
-python export.py --weights yolov7-d6.pt --grid --end2end --simplify --topk-all 100 --iou-thres 0.65 --conf-thres 0.35 --max-wh 7680
