Usage

Installation

See get_started.md.

Basic Usage

See MMDetection documents. Especially, see this document to evaluate and train existing models on COCO.

Examples

We show examples to evaluate and train UniverseNet-20.08 on COCO with 4 GPUs.

# evaluate pre-trained model
mkdir -p ${HOME}/data/checkpoints/
wget -P ${HOME}/data/checkpoints/ https://github.com/shinya7y/UniverseNet/releases/download/20.08/universenet50_2008_fp16_4x4_mstrain_480_960_2x_coco_20200815_epoch_24-81356447.pth
CONFIG_FILE=configs/universenet/universenet50_2008_fp16_4x4_mstrain_480_960_2x_coco.py
CHECKPOINT_FILE=${HOME}/data/checkpoints/universenet50_2008_fp16_4x4_mstrain_480_960_2x_coco_20200815_epoch_24-81356447.pth
GPU_NUM=4
bash tools/dist_test.sh ${CONFIG_FILE} ${CHECKPOINT_FILE} ${GPU_NUM} --eval bbox

# train model
CONFIG_FILE=configs/universenet/universenet50_2008_fp16_4x4_mstrain_480_960_2x_coco.py
CONFIG_NAME=$(basename ${CONFIG_FILE} .py)
WORK_DIR="${HOME}/logs/coco/${CONFIG_NAME}_`date +%Y%m%d_%H%M%S`"
GPU_NUM=4
bash tools/dist_train.sh ${CONFIG_FILE} ${GPU_NUM} --work-dir ${WORK_DIR} --seed 0

Even if you have one GPU, we recommend using tools/dist_train.sh and tools/dist_test.sh to avoid a SyncBN issue.

Introduction

English | 简体中文

MMDetection is an open source object detection toolbox based on PyTorch. It is a part of the OpenMMLab project.

The master branch works with PyTorch 1.3+. The old v1.x branch works with PyTorch 1.1 to 1.4, but v2.0 is strongly recommended for faster speed, higher performance, better design and more friendly usage.

Major features

Modular Design

We decompose the detection framework into different components and one can easily construct a customized object detection framework by combining different modules.
Support of multiple frameworks out of box

The toolbox directly supports popular and contemporary detection frameworks, e.g. Faster RCNN, Mask RCNN, RetinaNet, etc.
High efficiency

All basic bbox and mask operations run on GPUs. The training speed is faster than or comparable to other codebases, including Detectron2, maskrcnn-benchmark and SimpleDet.
State of the art

The toolbox stems from the codebase developed by the MMDet team, who won COCO Detection Challenge in 2018, and we keep pushing it forward.

Apart from MMDetection, we also released a library mmcv for computer vision research, which is heavily depended on by this toolbox.

Changelog

v2.17.0 was released in 28/09/2021. Please refer to changelog.md for details and release history. A comparison between v1.x and v2.0 codebases can be found in compatibility.md.

Benchmark and model zoo

Results and models are available in the model zoo.

Supported backbones:

Supported methods:

Some other methods are also supported in projects using MMDetection.

Installation

Please refer to get_started.md for installation.

Getting Started

Please see get_started.md for the basic usage of MMDetection. We provide colab tutorial, and full guidance for quick run with existing dataset and with new dataset for beginners. There are also tutorials for finetuning models, adding new dataset, designing data pipeline, customizing models, customizing runtime settings and useful tools.

Please refer to FAQ for frequently asked questions.

Contributing

We appreciate all contributions to improve MMDetection. Please refer to CONTRIBUTING.md for the contributing guideline.

Acknowledgement

MMDetection is an open source project that is contributed by researchers and engineers from various colleges and companies. We appreciate all the contributors who implement their methods or add new features, as well as users who give valuable feedbacks. We wish that the toolbox and benchmark could serve the growing research community by providing a flexible toolkit to reimplement existing methods and develop their own new detectors.
