Introduction

English | 简体中文

MMClassification is an open source image classification toolbox based on PyTorch. It is a part of the OpenMMLab project.

The 1.x branch works with PyTorch 1.6+.

Major features

• Various backbones and pretrained models
• Bag of training tricks
• Large-scale training configs
• High efficiency and extensibility
• Powerful toolkits

What's new

v1.0.0rc2 was released in 12/10/2022.

• Support Deit-3 backbone.
• Fix MMEngine version requirements.

v1.0.0rc1 was released in 30/9/2022.

• Support MViT, EdgeNeXt, Swin-Transformer V2, EfficientFormer and MobileOne.
• Support BEiT type transformer layer.

v1.0.0rc0 was released in 31/8/2022.

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.

The release candidate will last until the end of 2022, and during the release candidate, we will develop on the 1.x branch. And we will still maintain 0.x version still at least the end of 2023.

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