# ScaledYOLOv4 Ready-to-deploy Model

- The ScaledYOLOv4 deployment is based on the code of [ScaledYOLOv4](https://github.com/WongKinYiu/ScaledYOLOv4) and [Pre-trained Model on COCO](https://github.com/WongKinYiu/ScaledYOLOv4).

  - （1）The *.pt provided by [Official Repository](https://github.com/WongKinYiu/ScaledYOLOv4) should [Export the ONNX Model](#Export-the-ONNX-Model) to complete the deployment；
  - （2）The ScaledYOLOv4 model trained by personal data should [Export the ONNX Model](#%E5%AF%BC%E5%87%BAONNX%E6%A8%A1%E5%9E%8B). Refer to [Detailed Deployment Documents](#Detailed-Deployment-Documents) to complete the deployment.


## Export the ONNX Model


  Visit the official [ScaledYOLOv4](https://github.com/WongKinYiu/ScaledYOLOv4) github repository, follow the guidelines to download the `scaledyolov4.pt` model, and employ `models/export.py` to get the file in `onnx` format.  If you have any problems with the exported `onnx` model, refer to [ScaledYOLOv4#401](https://github.com/WongKinYiu/ScaledYOLOv4/issues/401) for solution.


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

  # Export the file in onnx format
  python models/export.py  --weights PATH/TO/scaledyolov4-xx.pt --img-size 640
  ```


## Download Pre-trained ONNX Model
