Welcome to the official implementation of YOLOv7 and YOLOv9. This repository will contains the complete codebase, pre-trained models, and detailed instructions for training and deploying YOLOv9.

## TL;DR

- This is the official YOLO model implementation with an MIT License.
- For quick deployment: you can directly install by pip+git:

```shell
pip install git+https://github.com/WongKinYiu/YOLO.git
yolo task.data.source=0 # source could be a single file, video, image folder, webcam ID
```

## Introduction

- [**YOLOv9**: Learning What You Want to Learn Using Programmable Gradient Information](https://arxiv.org/abs/2402.13616)
- [**YOLOv7**: Trainable Bag-of-Freebies Sets New State-of-the-Art for Real-Time Object Detectors](https://arxiv.org/abs/2207.02696)

## Installation

To get started using YOLOv9's developer mode, we recommand you clone this repository and install the required dependencies:

```shell
git clone git@github.com:WongKinYiu/YOLO.git
cd YOLO
pip install -r requirements.txt
```

## Features

<tr><td>

## Task

These are simple examples. For more customization details, please refer to [Notebooks](examples) and lower-level modifications **[HOWTO](docs/HOWTO.md)**.

## Training

To train YOLO on your machine/dataset:

1. Modify the configuration file `yolo/config/dataset/**.yaml` to point to your dataset.
2. Run the training script:

```shell
python yolo/lazy.py task=train dataset=** use_wandb=True
python yolo/lazy.py task=train task.data.batch_size=8 model=v9-c weight=False # or more args
```

### Transfer Learning

To perform transfer learning with YOLOv9:

```shell
python yolo/lazy.py task=train task.data.batch_size=8 model=v9-c dataset={dataset_config} device={cpu, mps, cuda}
```

### Inference

To use a model for object detection, use:

```shell
python yolo/lazy.py # if cloned from GitHub
python yolo/lazy.py task=inference \ # default is inference
                    name=AnyNameYouWant \ # AnyNameYouWant
                    device=cpu \ # hardware cuda, cpu, mps
                    model=v9-s \ # model version: v9-c, m, s
                    task.nms.min_confidence=0.1 \ # nms config
                    task.fast_inference=onnx \ # onnx, trt, deploy
                    task.data.source=data/toy/images/train \ # file, dir, webcam
                    +quite=True \ # Quite Output
yolo task.data.source={Any Source} # if pip installed
yolo task=inference task.data.source={Any}
```

### Validation

To validate model performance, or generate a json file in COCO format:

```shell
python yolo/lazy.py task=validation
python yolo/lazy.py task=validation dataset=toy
```
