Usage: train.py [OPTIONS] Train a GAN using the techniques described in the paper "Training Generative Adversarial Networks with Limited Data". Examples: # Train with custom images using 1 GPU. python train.py --outdir=~/training-runs --data=~/my-image-folder # Train class-conditional CIFAR-10 using 2 GPUs. python train.py --outdir=~/training-runs --data=~/datasets/cifar10.zip \ --gpus=2 --cfg=cifar --cond=1 # Transfer learn MetFaces from FFHQ using 4 GPUs. python train.py --outdir=~/training-runs --data=~/datasets/metfaces.zip \ --gpus=4 --cfg=paper1024 --mirror=1 --resume=ffhq1024 --snap=10 # Reproduce original StyleGAN2 config F. python train.py --outdir=~/training-runs --data=~/datasets/ffhq.zip \ --gpus=8 --cfg=stylegan2 --mirror=1 --aug=noaug Base configs (--cfg): auto Automatically select reasonable defaults based on resolution and GPU count. Good starting point for new datasets. stylegan2 Reproduce results for StyleGAN2 config F at 1024x1024. paper256 Reproduce results for FFHQ and LSUN Cat at 256x256. paper512 Reproduce results for BreCaHAD and AFHQ at 512x512. paper1024 Reproduce results for MetFaces at 1024x1024. cifar Reproduce results for CIFAR-10 at 32x32. Transfer learning source networks (--resume): ffhq256 FFHQ trained at 256x256 resolution. ffhq512 FFHQ trained at 512x512 resolution. ffhq1024 FFHQ trained at 1024x1024 resolution. celebahq256 CelebA-HQ trained at 256x256 resolution. lsundog256 LSUN Dog trained at 256x256 resolution.
