The code has been tested using Pytorch1.3 and CUDA10.0 on Ubuntu16.04.
You can run the following code to sketch model on Cifar-10:
python sketch_cifar.py
--data_set cifar10
--data_path ../data/cifar10/
--sketch_model ./experiment/pretrain/resnet56.pt
--job_dir ./experiment/resnet56/sketch/
--arch resnet
--cfg resnet56
--lr 0.01
--lr_decay_step 50 100
--num_epochs 150
--gpus 0
--sketch_rate [0.6]*27
--weight_norm_method l2
You can run the following code to sketch model on Imagenet:
python sketch_imagenet.py
--data_set imagenet
--data_path ../data/imagenet/
--sketch_model ./experiment/pretrain/resnet50.pth
--job_dir ./experiment/resnet50/sketch/
--arch resnet
--cfg resnet50
--lr 0.1
--lr_decay_step 30 60
--num_epochs 90
--gpus 0
--sketch_rate [0.6]*16
--weight_norm_method l2
Follow the command below to verify our pruned models:
python test.py
--data_set cifar10
--data_path ../data/cifar10
--arch resnet
--cfg resnet56
--sketch_model ./experiment/result/sketch_resnet56.pt
--sketch_rate [0.6]*27

You can use the following command to install the thop python package when you need to calculate the flops of the model:
pip install thop
python get_flops_params.py
--data_set cifar10
--input_image_size 32
--arch resnet
--cfg resnet56
--sketch_rate [0.6]*27
