# yolov5
The Pytorch implementation is [ultralytics/yolov5](https://github.com/ultralytics/yolov5).
Currently, we support yolov5 v1.0(yolov5s only), v2.0 and v3.0.
- For yolov5 v3.0, please visit [yolov5 release v3.0](https://github.com/ultralytics/yolov5/releases/tag/v3.0), and use the latest commit of this repo.
- For yolov5 v2.0, please visit [yolov5 release v2.0](https://github.com/ultralytics/yolov5/releases/tag/v2.0), and checkout commit ['7cd092d'](https://github.com/wang-xinyu/tensorrtx/commit/7cd092d38289123442157cf7defab78e816f4440) of this repo or use the latest commit.
- For yolov5 v1.0, please visit [yolov5 release v1.0](https://github.com/ultralytics/yolov5/releases/tag/v1.0), and checkout commit ['0504551'](https://github.com/wang-xinyu/tensorrtx/commit/0504551c0b7d0bac5f998eda349810ba410715de) of this repo.
## Config
- Choose the model s/m/l/x by `NET` macro in yolov5.cpp
- Input shape defined in yololayer.h
- Number of classes defined in yololayer.h
- FP16/FP32 can be selected by the macro in yolov5.cpp
- GPU id can be selected by the macro in yolov5.cpp
- NMS thresh in yolov5.cpp
- BBox confidence thresh in yolov5.cpp
- Batch size in yolov5.cpp
## How to Run, yolov5s as example
```
1. generate yolov5s.wts from pytorch implementation with yolov5s.pt
git clone https://github.com/wang-xinyu/tensorrtx.git
git clone https://github.com/ultralytics/yolov5.git
// download its weights 'yolov5s.pt'
cd yolov5
cp ../tensorrtx/yolov5/gen_wts.py .
// ensure the file name is yolov5s.pt and yolov5s.wts in gen_wts.py
python gen_wts.py
// a file 'yolov5s.wts' will be generated.
2. put yolov5s.wts into yolov5, build and run
mv yolov5s.wts ../tensorrtx/yolov5/
cd ../tensorrtx/yolov5
// ensure the macro NET in yolov5.cpp is s
mkdir build
cd build
cmake ..
make
sudo ./yolov5 -s // serialize model to plan file i.e. 'yolov5s.engine'
sudo ./yolov5 -d ../samples // deserialize plan file and run inference, the images in samples will be processed.
3. check the images generated, as follows. _zidane.jpg and _bus.jpg
