sapsan 0.2.8

Sapsan project

Sapsan

Sapsan is a pipeline for easy Machine Learning implementation in scientific projects. That being said, its primary goal and featured models are geared towards dynamic MHD turbulence subgrid modeling. Sapsan will soon feature Physics-Informed Machine Learning models in its set of tools to accurately capture the turbulent nature applicable to Core-Collapse Supernovae.

Feel free to check out a website version at sapsan.app. The interface is indentical to the GUI of the local version of Sapsan, except lacking the ability to edit the model code on the fly.

Sapsan's Wiki

Please refer to Sapsan's github wiki to learn more about framework's details and capabilities.

Quick Start

1. Clone from git (recommended)

git clone https://github.com/pikarpov-LANL/Sapsan.git
cd Sapsan/
python setup.py install

For GPU enabled version change the last line to

python setup_gpu.py install

2. Install via pip (cpu-only)

pip install sapsan

Note: make sure you are using the latest release version

Run Examples

To make sure everything is alright and to familiarize yourself with the interface, please run the following CNN example on 3D data:

jupyter notebook sapsan/examples/cnn_example.ipynb

alternatively, you can try out the physics-informed convolutional auto-encoder (PICAE) example on random 3D data:

jupyter notebook sapsan/examples/picae_example.ipynb

or a KRR example on 2D data:

jupyter notebook sapsan/examples/krr_example.ipynb
