This repository contains our implementation of the following paper:

Yuki Endo: "User-Controllable Latent Transformer for StyleGAN Image Layout Editing," Computer Graphpics Forum (Pacific Graphics 2022) [Project] [PDF (preprint)]

Prerequisites

1. Python 3.8
2. PyTorch 1.9.0
3. Flask
4. Others (see env.yml)

Preparation

Inference with our pre-trained models

This interface can be locally launched with

python interface/flask_app.py --checkpoint_path=pretrained_models/latent_transformer/cat.pt

The interface can be accessed via http://localhost:8000/.

Training

The latent transformer can be trained with

python scripts/train.py --exp_dir=results --stylegan_weights=pretrained_models/stylegan2-cat-config-f.pt

To perform training with your dataset, you need first to train StyleGAN2 on your dataset using rosinality's code and then run the above script with specifying the trained weights.
