## Introduction
MMRazor is an open source model compression toolbox based on PyTorch. It is
a part of the [OpenMMLab ](https://openmmlab.com/ ) project.
< details open > < summary > Major features< / summary >
- **All in one**
MMRazor includes Neural Architecture Search（ （ （
And it supports the combination of different types of algorithms.
- **General CV Model Compression ToolBox**
2021-12-23 12:35:51 +08:00
Thanks to OpenMMLab, the algorithms in MMRazor can be quickly applied to different CV tasks, making the development of model compression algorithms once and for all.
2021-12-23 10:35:49 +08:00
- **Decouple model and compression algorithm**
MMRazor has a variety of built-in automation mechanisms, allowing developers to implement model compression algorithms without modifying the raw model code, such as:
- OP can be modified code-free.
- Feature maps in the middle layers can be obtained code-free.
- Automatically obtain and analyze the connection between nn.Module.
- And More ...
- **Flexible and Modular Design**
We decompose the model compression algorithms into different components, making it much easier and more flexible to build a new algorithm by combining different components.
