Scaled MMD GANs

Official Tensorflow implementation for reproducing results of On gradient regularizers for MMD GANs.

Setup

Install:

pip install -r requirements.txt

The GPU compatible version of tensorflow is required for this code to work.

Download CelebA dataset:

cd scripts
OUTPUT_DATA_DIR=/path/to/output/directory/
python scripts/download.py celebA -- $OUTPUT_DATA_DIR

Download ImageNet dataset:

Please download ILSVRC2012 dataset from http://image-net.org/download-images

Preprocess ImageNet dataset:

IMAGENET_TRAIN_DIR=/path/to/imagenet/train/ 
PREPROCESSED_DATA_DIR=/path/to/save_dir/
TFRECORDS_DATA_DIR=/path/to/output/tfrecords 
bash preprocess.sh $IMAGENET_TRAIN_DIR $PREPROCESSED_DATA_DIR
build_imagenet_data --train_directory=$PREPROCESSED_DATA_DIR --output_directory=$TFRECORDS_DATA_DIR

Download inception model:

python source/inception/download.py --outfile=datasets/inception_model

Training

Unsupervised image generation of 64x64 ImageNet:

DATADIR=/path/to/datadir/
OUTDIR=/path/to/outputdir/
CONFIG=configs/imagenet_smmd.yml
# multi-GPU: 3 GPUs
CUDA_VISIBLE_DEVICES=0,1,2 python gan/main.py -dataset imagenet -data_dir $DATADIR -name  -config_file $CONFIG -out_dir $OUTDIR -multi_gpu true
