Discrimination-aware Channel Pruning for Deep Neural Networks (NeurIPS 2018)

License

Architecture of Discrimination-aware Channel Pruning (DCP)

Architecture of DCP

Training Algorithm

Recent Update

2019.05.10: We release a new version of dcp.

2018.11.27: We release the source code of dcp.

Requirements

  • python 2.7
  • pytorch 0.4
  • tensorflow
  • pyhocon
  • prettytable

Testing

  1. Download the pre-trained pruned model from the model zoo.

  2. Add DCP into PYTHONPATH.

# This is my path of DCP. You need to change to your path of DCP.
export PYTHONPATH=/home/liujing/Codes/Discrimination-aware-Channel-Pruning-for-Deep-Neural-Networks:$PYTHONPATH
  1. Set configuration for testing. You need to set save_path, data_path, dataset, pruning_rate, net_type, depth and the pretrained in dcp/test/test.hocon.
cd dcp/test/
vim test.hocon
  1. Run testing.
python main.py test.hocon

Channel Pruning Examples

  1. Download pre-trained mdoel.
  1. Add DCP into PYTHONPATH.
# This is my path of DCP. You need to change to your path of DCP.
export PYTHONPATH=/home/liujing/Codes/Discrimination-aware-Channel-Pruning-for-Deep-Neural-Networks:$PYTHONPATH
  1. Before channel pruning, you need to add discrimination-aware loss and fine tune the whole network. You need to set save_path, data_path, experiment_id and the pretrained in dcp/auxnet/cifar10_resnet.hocon.
cd dcp/auxnet/
vim cifar10_resnet.hocon
  1. Add discrimination-aware loss and conduct fine-tuning.
python main.py cifar10_resnet.hocon
  1. Set configuration for channel selection. You need to set save_path, data_path, pruning_rate and experiment_id in dcp/channel_selection/cifar10_resnet.hocon. Additionally, you need to set pretrained to the path of best_model_with_aux_fc.pth in check_point folder.
cd dcp/channel_selection/
vim cifar10_resnet.hocon
  1. Conduct channel selection.
python main.py cifar10_resnet.hocon
  1. Set configuration for fine-tuning. You need to set save_path, data_path, and experiment_id in dcp/finetune/cifar10_resnet.hocon. Additionally, you need to set pretrained to the path of model_xxx_cs_000.pth in check_point folder.
cd dcp/finetune/
vim cifar10_resnet.hocon
  1. Fine-tune the pruned model.
python main cifar10_resnet.hocon
