• WGAN
• WGAN-GP
• SN-GAN

Requirements

• python 3.6
• Install python packages

  pip install -U pip setuptools
  pip install -r requirements.txt

Generate GIF

python tools/sample2gif.py --logdir path/to/logdir

e.g.

python tools/sample2gif.py --logdir ./logs/DCGAN_CIFAR10

output GIF is ./logs/DCGAN_CIFAR10/progress.gif
