Freeze D: A Simple Baseline for Fine-tuning GANs

Code for "Freeze Discriminator: A Simple Baseline for Fine-tuning GANs".

The code is heavily based on the StyleGAN-pytorch and SNGAN-projection-chainer codes.

See stylegan and projection directory for StyleGAN and SNGAN-projection experiments, respectively.
