Install
git submodule update --init --recursive
conda install -y pytorch torchvision -c pytorch
conda install -y numpy
conda install -y scikit-image
conda install -y -c anaconda cmake
conda install -y -c conda-forge ffmpeg
pip install svgwrite
pip install svgpathtools

pip install visdom
python setup.py install
Install using poetry
prerequisite
install python 3.7, poetry and ffmpeg
# install poetry (mac, linux)
curl -sSL https://raw.githubusercontent.com/python-poetry/poetry/master/get-poetry.py | python -
# install ffmpeg
(macos)
brew install ffmpeg
(linux)
sudo apt install ffmpeg
or use conda
conda install -y -c conda-forge ffmpeg
Install python packages
# install all python dependencies
poetry install
# install pydiffvg
poetry run python setup.py install
Now to run the apps, just add poetry run before each of the commands below, e.g.
poetry run python single_circle.py
Building in debug mode
python setup.py build --debug install
Run
cd apps
