GitHub stars GitHub forks GitHub watchers Gitter

news: yolov5 support

INTRODUCTION

The project is the encapsulation of nvidia official yolo-tensorrt implementation. And you must have the trained yolo model(.weights) and .cfg file from the darknet (yolov3 & yolov4). For the yolov5 ,you should prepare the model file (yolov5s.yaml) and the trained weight file (yolov5s.pt) from pytorch.

  • yolov5s , yolov5m , yolov5l , yolov5x tutorial
  • yolov4 , yolov4-tiny
  • yolov3 , yolov3-tiny

Features

  • inequal net width and height
  • batch inference
  • support FP32,FP16,INT8
  • dynamic input size

PLATFORM & BENCHMARK

  • windows 10
  • ubuntu 18.04
  • L4T (Jetson platform)

WRAPPER

Prepare the pretrained .weights and .cfg model.

Detector detector;
Config config;

std::vector<BatchResult> res;
detector.detect(vec_image, res)

Build and use yolo-trt as DLL or SO libraries

windows10

  • dependency : TensorRT 7.1.3.4 , cuda 11.0 , cudnn 8.0 , opencv4 , vs2015

  • build:

    open MSVC sln/sln.sln file

    • dll project : the trt yolo detector dll
    • demo project : test of the dll

ubuntu & L4T (jetson)

The project generate the libdetector.so lib, and the sample code. If you want to use the libdetector.so lib in your own project,this cmake file perhaps could help you .

git clone https://github.com/enazoe/yolo-tensorrt.git
cd yolo-tensorrt/
mkdir build
cd build/
cmake ..
make
./yolo-trt
