Pytorch_GAN_CelebA

Pytorch implementation of DCGAN, CDCGAN, LSGAN, WGAN and WGAN-GP for CelebA dataset.

Usage

1. Download the CelebA dataset, and aligned version is used in this repo.

2. Clone the repo

$ git clone https://github.com/AndrewZhuZJU/Pytorch_GAN_CelebA.git
$ cd Pytorch_GAN_CelebA

3. Training

To train any GAN please use main_**.py. For example,

$ python main_DCGAN.py

Not that all the setting parameters for the modesl are in args.py, please change properly.
