Overview

About

This repo contains the official implementation of the Aligning Latent and Image Spaces to Connect the Unconnectable paper. It is a GAN model which can generate infinite images of diverse and complex scenes.

ALIS generation example

Installation

To install, run the following command:

conda env create --file environment.yml --prefix ./env
conda activate ./env

Note: the tensorboard requirement is crucial, because otherwise upfirdn2d will not compile for some magical reason.

Training

To train the model, navigate to the project directory and run:

python infra/launch_local.py hydra.run.dir=. +experiment_name=my_experiment_name +dataset=dataset_name num_gpus=4

where dataset_name is the name of the dataset without .zip extension inside data/ directory (you can easily override the paths in configs/main.yml). So make sure that data/dataset_name.zip exists and should be a plain directory of images. See StyleGAN2-ADA repo for additional data format details. This training command will create an experiment inside experiments/ directory and will copy the project files into it. This is needed to isolate the code which produces the model.

Inference

The inference example can be found in notebooks/generate.ipynb

Data format

We use the same data format as the original StyleGAN2-ADA repo: it is a zip of images. It is assumed that all data is located in a single directory, specified in configs/main.yml. Put your datasets as zip archives into data/ directory.

Pretrained checkpoints

We provide checkpoints for the following datasets:

  • LHQ 1024x1024 with FID = 7.8. Note: this checkpoint has patch size of 1024x512, i.e. the image is generated in just 2 halves.

License

The project is based on the StyleGAN2-ADA repo developed by NVidia. I am not a lawyer, but I suppose that NVidia License applies to this project then.
