MMRazor V1.0.0 Release

v1.0.0 (24/04/2023)

We are excited to announce the first official release of MMRazor 1.0.

Highlights

• MMRazor quantization is released, which has got through task models and model deployment. With its help, we can quantize and deploy pre-trained models in OpenMMLab to specified backend quickly.

New Features & Improvements

NAS

• Update searchable model. (#438)
• Update NasMutator to build search_space in NAS. (#426)

Pruning

• Add a new pruning algorithm named GroupFisher. We support the full pipeline for GroupFisher, including pruning, finetuning and deployment.(#459)

KD

• Support stopping distillation after a certain epoch. (#455)
• Support distilling rtmdet with mmrazor, refer to here. (open-mmlab/mmyolo#544)
• Add mask channel in MGD Loss. (#461)

Quantization

• Support two quantization types: QAT and PTQ (#513)
• Support various quantization bits. (#513)
• Support various quantization methods, such as per_tensor / per_channel, symmetry / asymmetry and so on. (#513)
• Support deploy quantized models to multiple backends, such as OpenVINO, TensorRT and so on. (#513)
• Support applying quantization algorithms to multiple task repos directly, such as mmcls, mmdet and so on. (#513)

Bug Fixes

• Fix split in Darts config. (#451)
• Fix a bug in Recorders. (#446)
• Fix a bug when using get_channel_unit.py. (#432)
• Fix a bug when deploying a pruned model to cuda. (#495)
