trt_yolov8

detection/classification/segmentation/pose_estimation based on yolov8, codes come from tensorrtx, with some modifications.

How to generate plan file(trt/engine) from pytorch models ?

.pt --> .wts --> .trt/.engine
  1. download default .pt models of yolov8/n/s/m/...(det/cls/seg/pose) from github (or trained by yourself)
  2. convert .pt to .wts using samples/gen_wts.py
  3. convert .wts to .engine using samples/trt_yolov8_wts_2_engine.cpp (change classes number before compiling)

.pt -> .wts

python3 samples/gen_wts.py [-w] [.pt] [-o] [.wts] [-t] [detect/seg/cls]

python3 samples/gen_wts.py -w yolov8n.pt -o yolov8n.wts -t detect
python3 samples/gen_wts.py -w yolov8n-seg.pt -o yolov8n-seg.wts -t seg
python3 samples/gen_wts.py -w yolov8n-pose.pt -o yolov8n-pose.wts
python3 samples/gen_wts.py -w yolov8n-cls.pt -o yolov8n-cls.wts -t cls
python3 samples/gen_wts.py -w yolov8s.pt -o yolov8s.wts -t detect
python3 samples/gen_wts.py -w yolov8s-seg.pt -o yolov8s-seg.wts -t seg
python3 samples/gen_wts.py -w yolov8s-pose.pt -o yolov8s-pose.wts
python3 samples/gen_wts.py -w yolov8s-cls.pt -o yolov8s-cls.wts -t cls
...

.wts -> .engine

./trt_yolov8_wts_2_engine [-det/-seg/-pose/-cls] [.wts] [.engine] [n/s/m/l/x/n2/s2/m2/l2/x2/n6/s6/m6/l6/x6]

CUDA 11.1 + TensorRT 8.5 for this repository (tested)

How to build trt_yolov8 ?

we can build trt_yolov8 separately.

change the value of kNumClass/kClsNumClass in include/config.h to your classes number (80 by default for coco dataset and 1000 by default for imagenet dataset) before building.

  1. set the right library path and include path for TensorRT in CMakeLists.txt
  2. mkdir build && cd build
  3. cmake ..
  4. make -j8

all lib files saved to build/libs, all samples saved to build/samples. please refer to videopipe about how to run samples for trt_yolov8.
