Introduction

English | 简体中文

MMGeneration is a powerful toolkit for generative models, especially for GANs now. It is based on PyTorch and MMCV. The master branch works with PyTorch 1.5+.

Major Features

• High-quality Training Performance: We currently support training on Unconditional GANs, Internal GANs, and Image Translation Models. Support for conditional models will come soon.
• Powerful Application Toolkit: A plentiful toolkit containing multiple applications in GANs is provided to users. GAN interpolation, GAN projection, and GAN manipulations are integrated into our framework. It's time to play with your GANs! (Tutorial for applications)
• Efficient Distributed Training for Generative Models: For the highly dynamic training in generative models, we adopt a new way to train dynamic models with MMDDP. (Tutorial for DDP)
• New Modular Design for Flexible Combination: A new design for complex loss modules is proposed for customizing the links between modules, which can achieve flexible combination among different modules. (Tutorial for new modular design)

Highlight

• Positional Encoding as Spatial Inductive Bias in GANs (CVPR2021) has been released in MMGeneration. [Config], [Project Page]
• Conditional GANs have been supported in our toolkit. More methods and pre-trained weights will come soon.
• Mixed-precision training (FP16) for StyleGAN2 has been supported. Please check the comparison between different implementations.

Changelog

v0.7.1 was released on 30/04/2022. Please refer to changelog.md for details and release history.

Installation

MMGeneration depends on PyTorch and MMCV. Below are quick steps for installation.

Step 1. Install PyTorch following official instructions, e.g.

pip3 install torch torchvision

Step 2. Install MMCV with MIM.

pip3 install openmim
mim install mmcv-full

Step 3. Install MMGeneration from source.

git clone https://github.com/open-mmlab/mmgeneration.git
cd mmgeneration
pip3 install -e .[all]

Please refer to get_started.md for more detailed instruction.
