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 master branch works with PyTorch 1.5+.

Major features

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

What's new

v0.22.0 was released in 30/3/2022.

Highlights of the new version: - Support a series of CSP Network, such as CSP-ResNet, CSP-ResNeXt and CSP-DarkNet. - A new CustomDataset class to help you build dataset of yourself! - Support new backbones - ConvMixer, RepMLP and new dataset - CUB dataset.

v0.21.0 was released in 4/3/2022.

Highlights of the new version: - Support ResNetV1c and Wide-ResNet, and provide pre-trained models. - Support dynamic input shape for ViT-based algorithms. Now our ViT, DeiT, Swin-Transformer and T2T-ViT support forwarding with any input shape. - Reproduce training results of DeiT. And our DeiT-T and DeiT-S have higher accuracy comparing with the official weights.

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