Dependencies

• Python 3
• WolframScript (either through a Mathematica install or standalone)
• numpy
• scipy
• scikit-learn
• optional for running simulations: pandas, numba

Installation

To install the package and its python dependencies using pip, clone the repository, descend into the landau/ folder, and run

pip install -e .

To automatically include the optional dependencies for running test simulations, instead run

pip install -e '.[simulation]'

WolframScript must also be installed on the system. This can be accomplished by installing Mathematica (and using the prepackaged Extras installer on Mac) or installed as a standalone package available for free download here: https://www.wolfram.com/wolframscript/
