# ScaledYOLOv4准备部署模型

- ScaledYOLOv4部署实现来自[ScaledYOLOv4](https://github.com/WongKinYiu/ScaledYOLOv4)的代码，和[基于COCO的预训练模型](https://github.com/WongKinYiu/ScaledYOLOv4)。

  - （1）[官方库](https://github.com/WongKinYiu/ScaledYOLOv4)提供的*.pt通过[导出ONNX模型](#导出ONNX模型)操作后，可进行部署；
  - （2）自己数据训练的ScaledYOLOv4模型，按照[导出ONNX模型](#%E5%AF%BC%E5%87%BAONNX%E6%A8%A1%E5%9E%8B)操作后，参考[详细部署文档](#详细部署文档)完成部署。


## 导出ONNX模型


  访问[ScaledYOLOv4](https://github.com/WongKinYiu/ScaledYOLOv4)官方github库，按照指引下载安装，下载`scaledyolov4.pt` 模型，利用 `models/export.py` 得到`onnx`格式文件。如果您导出的`onnx`模型出现问题，可以参考[ScaledYOLOv4#401](https://github.com/WongKinYiu/ScaledYOLOv4/issues/401)的解决办法

  ```bash
  #下载ScaledYOLOv4模型文件
  Download from the goole drive https://drive.google.com/file/d/1aXZZE999sHMP1gev60XhNChtHPRMH3Fz/view?usp=sharing

  # 导出onnx格式文件
  python models/export.py  --weights PATH/TO/scaledyolov4-xx.pt --img-size 640
  ```


## 下载预训练ONNX模型
