Neural Network Panning

Neural Network Panning: Screening the Optimal Sparse Network Before Training

Introduce

This project is a PyTorch implementation of the Panning paper, including several pruning before training methods tested in the paper.

Structure

• models: (lenet,resnet,vgg) Three models and the model class containing the mask
• pruner: Pruning algorithm
• runs: Output folder to store weights, evaluation information, etc.
• utils: custom helper function

Environment

The code has been tested to run on Python3.

Some package versions are as follows:

• torch == 1.7.1
• numpy == 1.18.5
• tensorboardX==2.4

Run

• E.g. cifar10/vgg19 prune ratio: 90%

# Panning
python main.py --config 'cifar10/vgg19/90' --run 'test' --prune_mode 'panning'

# RLPanning
python main.py --config 'cifar10/vgg19/90' --run 'test' --prune_mode 'rlpanning'

# SynFlow
python main.py --config 'cifar10/vgg19/90' --run 'test' --rank_algo 'synflow' --prune_mode 'rank'

• E.g. mnist/lenet5 prune ratio: 99.9%

python main.py --config 'mnist/lenet5/99.9' --run 'test' --prune_mode 'panning'

• Model optional: lenet, vgg, resnet

• Dataset optional: fashionmnist, mnist, cifar10, cifar100(Other datasets need to be manually downloaded to the local)

• All parameters(The default parameters are determined by the configs.py):

  Console Parameters	Remark
  config = ''	# Select Dataset, Model, and Pruning Rate
  pretrained = ''	# Path to load pretrained model
  run = 'test'	# Experimental Notes
  rank_algo = 'snip'	# Choose a pruning algorithm (snip, grasp, synflow, snip_ori, grasp_ori)
  prune_mode = 'rank'	# Choose a pruning mode (panning, rlpanning, dense, rank, rank/random, rank/iterative)
  dp = '../Data'	# Modify the path of the dataset
  storage_mask = 0	# Store the resulting mask
  save_model = 0	# Store the Panning agent
