}

Please contact Yunseok Jang if you have any question.

How to Use

1. Environment Setup

conda create -n l2lda -y
source activate l2lda
conda config --add channels conda-forge
conda install -c conda-forge python=3.6.4 numba -y
# conda install -c anaconda cudatoolkit=10.0 cudnn=7.6 -y
conda install pytorch=1.1.0 torchvision=0.3.0 cudatoolkit=10.0 -c pytorch -y
pip install requests gpustat tensorboardX tensorflow-gpu visdom tqdm matplotlib scikit-image

# I've forked and included this code base
# git clone https://github.com/revbucket/mister_ed.git
# Also, this repo includes edited version of Synced Batch Norm from this repository
# git clone https://github.com/vacancy/Synchronized-BatchNorm-PyTorch

Then, add mister_ed package setting to conda environment.

conda install conda-build
cd ./mister_ed
conda develop .

# Download pretrained ResNet Classifier trained on CIFAR-10 dataset
python scripts/setup_cifar.py
mv pretrained_models/ ../
cd ..

Optional) Download our pretrained classifiers.

# Note: For CIFAR 10 model, please check the detailed architecture in mister_ed/cifar10/cifar_resnets.py
wget https://www.dropbox.com/s/cnw79x2mv4qffw4/evaluation.zip -O evaluation.zip --no-check-certificate
unzip evaluation.zip

Optional) If you want to play with Tiny Imagenet dataset, you need to preprocess the dataset via the following commands.

mkdir datasets
cd datasets
wget http://cs231n.stanford.edu/tiny-imagenet-200.zip
unzip tiny-imagenet-200.zip
rm -f tiny-imagenet-200.zip
mv tiny-imagenet-200 tinyimagenet
cd ../
python tiny_imagenet_val_format.py

2. Train a new classifier

b. CIFAR-10

CUDA_VISIBLE_DEVICES=0 python main.py --f_classifier_name='resnet20' --dataset=cifar10 --is_rgb=True --img_size=32 --epsilon=0.031372549 --g_optimizer=sgd --g_lr=0.01 --f_pretrain=True --g_method=3 --train_g_iter=10 --g_ministep_size=0.25 --dsgan_lambda=0.5 --g_mini_update_style=2 --f_update_style=1 --num_gpu=1

c. Tiny Imagenet
