Introduction

MMPreTrain is an open source pre-training toolbox based on PyTorch. It is a part of the OpenMMLab project.

The main branch works with PyTorch 1.8+.

Major features

• Various backbones and pretrained models
• Rich training strategies(supervised learning, self-supervised learning, etc.)
• Bag of training tricks
• Large-scale training configs
• High efficiency and extensibility
• Powerful toolkits for model analysis and experiments

What's new

🌟 v1.0.0rc7 was released in 07/04/2023

• Integrated Self-supervised learning algorithms from MMSelfSup, such as MAE, BEiT, etc.
• Support RIFormer, a simple but effective vision backbone by removing token mixer.
• Add t-SNE visualization.
• Refactor dataset pipeline visualization.

Update of previous versions

• Support LeViT, XCiT, ViG, ConvNeXt-V2, EVA, RevViT, EfficientnetV2, CLIP, TinyViT and MixMIM backbones.
• Reproduce the training accuracy of ConvNeXt and RepVGG.
• Support confusion matrix calculation and plot.
• Support multi-task training and testing.
• Support Test-time Augmentation.
• Upgrade API to get pre-defined models of MMPreTrain.
• Refactor BEiT backbone and support v1/v2 inference.

This release introduced a brand new and flexible training & test engine, but it's still in progress. Welcome to try according to the documentation.

And there are some BC-breaking changes. Please check the migration tutorial.

Please refer to changelog for more details and other release history.
