This is an implementation of Coulomb GANs: Provably Optimal Nash Equilibria via Potential Fields in Chainer >= v2.

Requirements

Chainer >= v2, OpenCV, etc.
The scripts work on Python 2.7.13 and 3.6.1.

How to generate images

$ python generate_image.py example_food-101/config.py -p example_food-101/trained-params_gen_update-000128000.npz

You can generate various images by changing the random_seed option.

$ python generate_image.py example_food-101/config.py -r 1 -p example_food-101/trained-params_gen_update-000128000.npz

Example Food-101

Dataset

I resized the images to 64x64 before training.
