Introduction

The main branch works with PyTorch 1.8 (required by some self-supervised methods) or higher (we recommend PyTorch 1.12). You can still use PyTorch 1.6 for supervised classification methods.

OpenMixup is an open-source toolbox for supervised, self-, and semi-supervised visual representation learning with mixup based on PyTorch, especially for mixup-related methods.

Major Features

• Modular Design. OpenMixup follows a similar code architecture of OpenMMLab projects, which decompose the framework into various components, and users can easily build a customized model by combining different modules. OpenMixup is also transplantable to OpenMMLab projects (e.g., MMSelfSup).

• All in One. OpenMixup provides popular backbones, mixup methods, semi-supervised, and self-supervised algorithms. Users can perform image classification (CNN & Transformer) and self-supervised pre-training (contrastive and autoregressive) under the same framework.

• Standard Benchmarks. OpenMixup supports standard benchmarks of image classification, mixup classification, self-supervised evaluation, and provides smooth evaluation on downstream tasks with open-source projects (e.g., object detection and segmentation on Detectron2 and MMSegmentation).

• State-of-the-art Methods. Openmixup provides awesome lists of popular mixup and self-supervised methods. OpenMixup is updating to support more state-of-the-art image classification and self-supervised methods.

News and Updates

[2022-12-16] OpenMixup v0.2.7 is released (issue #35).

[2022-12-02] Update new features and documents of OpenMixup v0.2.6 (issue #24, issue #25, issue #31, and issue #33). Update the official implementation of MogaNet.

[2022-09-14] OpenMixup v0.2.6 is released (issue #20).

Installation

OpenMixup is compatible with Python 3.6/3.7/3.8/3.9 and PyTorch >= 1.6. Here are quick installation steps for development:

conda create -n openmixup python=3.8 pytorch=1.12 cudatoolkit=11.3 torchvision -c pytorch -y
conda activate openmixup
pip install openmim
mim install mmcv-full
git clone https://github.com/Westlake-AI/openmixup.git
cd openmixup
python setup.py develop

Please refer to install.md for more detailed installation and dataset preparation.

Getting Started

OpenMixup supports Linux and macOS. It enables easy implementation and extensions of mixup data augmentation methods in existing supervised, self-, and semi-supervised visual recognition models. Please see get_started.md for the basic usage of OpenMixup.

Training and Evaluation Scripts

Here, we provide scripts for starting a quick end-to-end training with multiple GPUs and the specified CONFIG_FILE.

bash tools/dist_train.sh ${CONFIG_FILE} ${GPUS} [optional arguments]

For example, you can run the script below to train a ResNet-50 classifier on ImageNet with 4 GPUs:

CUDA_VISIBLE_DEVICES=0,1,2,3 PORT=29500 bash tools/dist_train.sh configs/classification/imagenet/resnet/resnet50_4xb64_cos_ep100.py 4

After trianing, you can test the trained models with the corresponding evaluation script:

bash tools/dist_test.sh ${CONFIG_FILE} ${GPUS} ${PATH_TO_MODEL} [optional arguments]

Development

Please see Tutorials for more developing examples and tech details:

• config files
• add new dataset
• data pipeline
• add new modules
• customize schedules
• customize runtime
• benchmarks

Overview of Model Zoo

Please refer to Mixup Benchmarks for the benchmarking results of existing mixup methods, and Model Zoos for comprehensive collection of mainstream backbones and self-supervised algorithms. We also provide the paper lists of Awesome Mixups for your reference. Checkpoints and training logs will be updated soon!
