# DCGAN in Tensorflow

Tensorflow implementation of [Deep Convolutional Generative Adversarial Networks](http://arxiv.org/abs/1511.06434) which is a stabilize Generative Adversarial Networks. The referenced torch code can be found [here](https://github.com/soumith/dcgan.torch).

* [Brandon Amos](http://bamos.github.io/) wrote an excellent [blog post](http://bamos.github.io/2016/08/09/deep-completion/) and [image completion code](https://github.com/bamos/dcgan-completion.tensorflow) based on this repo.
* *To avoid the fast convergence of D (discriminator) network, G (generator) network is updated twice for each D network update, which differs from original paper.*

## Prerequisites

- Python 2.7 or Python 3.3+
- [Tensorflow 0.12.1](https://github.com/tensorflow/tensorflow/tree/r0.12)
- [SciPy](http://www.scipy.org/install.html)
- [pillow](https://github.com/python-pillow/Pillow)
- [tqdm](https://pypi.org/project/tqdm/)
- (Optional) [moviepy](https://github.com/Zulko/moviepy) (for visualization)
- (Optional) [Align&Cropped Images.zip](http://mmlab.ie.cuhk.edu.hk/projects/CelebA.html) : Large-scale CelebFaces Dataset


## Usage

First, download dataset with:

    $ python download.py mnist celebA

To train a model with downloaded dataset:

    $ python main.py --dataset mnist --input_height=28 --output_height=28 --train
    $ python main.py --dataset celebA --input_height=108 --train --crop

To test with an existing model:

    $ python main.py --dataset mnist --input_height=28 --output_height=28
    $ python main.py --dataset celebA --input_height=108 --crop

Or, you can use your own dataset (without central crop) by:

    $ mkdir data/DATASET_NAME
    ... add images to data/DATASET_NAME ...
    $ python main.py --dataset DATASET_NAME --train
    $ python main.py --dataset DATASET_NAME
    $ # example
    $ python main.py --dataset=eyes --input_fname_pattern="*_cropped.png" --train

If your dataset is located in a different root directory:

    $ python main.py --dataset DATASET_NAME --data_dir DATASET_ROOT_DIR --train
    $ python main.py --dataset DATASET_NAME --data_dir DATASET_ROOT_DIR
    $ # example
    $ python main.py --dataset=eyes --data_dir ../datasets/ --input_fname_pattern="*_cropped.png" --train
