Getting Started

Requirements

The main requirements of this work are:

• Python 3.7
• PyTorch == 1.5.0
• Torchvision == 0.6.0
• CUDA 10.2

We recommand using conda env to setup the experimental environments.

# Create environment
conda create -n DGNet python=3.7
conda activate DGNet

# Install PyTorch & Torchvision
pip install torch==1.5.0 torchvision==0.6.0

# Clone repo
git clone https://github.com/anonymous-9800/DGNet.git ./DGNet
cd ./DGNet

# Install other requirements
pip install -r requirements.txt

Trained models

Our trained models can be found here: Google Drive. And the pretrained cifar10 models can be found here: Google Drive. Unzip and place them into the DGNet folder.

Evaluate a trained DGNet

# CIFAR-10

# ResNet on ImageNet
sh ./scripts/imagenet_e.sh [ARCH] [PATH-TO-DATASET] [GPU-IDs] [PATH-TO-SAVE] [PATH-TO-TRAINED-MODEL]

# Example
