🥳 🚀 What's New 🔝

💎 v0.6.0 was released on 15/8/2023:

• Support YOLOv5 instance segmentation
• Support YOLOX-Pose based on MMPose
• Add 15 minutes instance segmentation tutorial.
• YOLOv5 supports using mask annotation to optimize bbox
• Add Multi-scale training and testing docs

For release history and update details, please refer to changelog.

✨ Highlight 🔝

We are excited to announce our latest work on real-time object recognition tasks, RTMDet, a family of fully convolutional single-stage detectors. RTMDet not only achieves the best parameter-accuracy trade-off on object detection from tiny to extra-large model sizes but also obtains new state-of-the-art performance on instance segmentation and rotated object detection tasks. Details can be found in the technical report. Pre-trained models are here.

MMYOLO currently implements the object detection and rotated object detection algorithm, but it has a significant training acceleration compared to the MMDeteciton version. The training speed is 2.6 times faster than the previous version.

📖 Introduction 🔝

MMYOLO is an open source toolbox for YOLO series algorithms based on PyTorch and MMDetection. It is a part of the OpenMMLab project.

The master branch works with PyTorch 1.6+.

Major features

- 🕹️ **Unified and convenient benchmark** MMYOLO unifies the implementation of modules in various YOLO algorithms and provides a unified benchmark. Users can compare and analyze in a fair and convenient way. - 📚 **Rich and detailed documentation** MMYOLO provides rich documentation for getting started, model deployment, advanced usages, and algorithm analysis, making it easy for users at different levels to get started and make extensions quickly. - 🧩 **Modular Design** MMYOLO decomposes the framework into different components where users can easily customize a model by combining different modules with various training and testing strategies. The figure above is contributed by RangeKing@GitHub, thank you very much! And the figure of P6 model is in [model_design.md](docs/en/recommended_topics/model_design.md).

🛠️ Installation 🔝

MMYOLO relies on PyTorch, MMCV, MMEngine, and MMDetection. Below are quick steps for installation. Please refer to the Install Guide for more detailed instructions.

conda create -n mmyolo python=3.8 pytorch==1.10.1 torchvision==0.11.2 cudatoolkit=11.3 -c pytorch -y
conda activate mmyolo
pip install openmim
mim install "mmengine>=0.6.0"
mim install "mmcv>=2.0.0rc4,<2.1.0"
mim install "mmdet>=3.0.0,<4.0.0"
git clone https://github.com/open-mmlab/mmyolo.git

👨‍🏫 Tutorial 🔝

MMYOLO is based on MMDetection and adopts the same code structure and design approach. To get better use of this, please read MMDetection Overview for the first understanding of MMDetection.

The usage of MMYOLO is almost identical to MMDetection and all tutorials are straightforward to use, you can also learn about MMDetection User Guide and Advanced Guide.

For different parts from MMDetection, we have also prepared user guides and advanced guides, please read our documentation.

📊 Overview of Benchmark and Model Zoo 🔝

Results and models are available in the model zoo.

❓ FAQ 🔝

Please refer to the FAQ for frequently asked questions.

🙌 Contributing 🔝

We appreciate all contributions to improving MMYOLO. Ongoing projects can be found in our GitHub Projects. Welcome community users to participate in these projects. Please refer to CONTRIBUTING.md for the contributing guideline.

🤝 Acknowledgement 🔝

MMYOLO is an open source project that is contributed by researchers and engineers from various colleges and companies.
