MMRazor is a model compression toolkit for model slimming and AutoML, which includes 3 mainstream technologies:

• Neural Architecture Search (NAS)
• Pruning
• Knowledge Distillation (KD)
• Quantization (in the next release)

It is a part of the OpenMMLab project.

Major features:

• Compatibility

  MMRazor can be easily applied to various projects in OpenMMLab, due to the similar architecture design of OpenMMLab as well as the decoupling of slimming algorithms and vision tasks.

• Flexibility

  Different algorithms, e.g., NAS, pruning and KD, can be incorporated in a plug-n-play manner to build a more powerful system.

• Convenience

  With better modular design, developers can implement new model compression algorithms with only a few codes, or even by simply modifying config files.

Below is an overview of MMRazor's design and implementation, please refer to tutorials for more details.

MMRazor v0.3.1 was released in 5/4/2022.

Results and models are available in the model zoo.

Supported algorithms:

MMRazor depends on PyTorch and MMCV.

Please refer to get_started.md for more detailed instruction.

Please refer to train.md and test.md for the basic usage of MMRazor. There are also tutorials:

• overview
• learn about configs
• customize architectures
• customize nas algorithms
• customize pruning algorithms
• customize kd algorithms
• customize mixed algorithms with our algorithm_components
• apply existing algorithms to other existing tasks

We appreciate all contributions to improve MMRazor. Please refer to CONTRUBUTING.md for the contributing guideline.

MMRazor is an open source project that is contributed by researchers and engineers from various colleges and companies. We appreciate all the contributors who implement their methods or add new features, as well as users who give valuable feedbacks. We wish that the toolbox and benchmark could serve the growing research community by providing a flexible toolkit to reimplement existing methods and develop their own new model compression methods.
