This README is incomplete (work in progress).

Setup

The code uses PyTorch-Lightning for training and Hydra for configuration. Other required packages are listed in install_requirements.sh.

# clone project
git clone https://github.com/catalys1/fractal-pretraining.git
cd fractal-pretraining

# [RECOMMENDED] set up a virtual environment
python3 -m venv venv_name  # choose your prefered venv name
source venv/bin/activate

# install requirements
bash install_requirements.sh
# install project in editable mode
pip install -e fractal_learning

Sample and Render Iterated Function Systems

See the fractals sub-package for details on sampling IFS codes and rendering fractal images.

Training

See the training sub-package for details on pre-training with fractal images, as well as finetuning on other datasets.
