PyVibDMC

A general purpose diffusion monte carlo code for studying vibrational problems

This package requires the following:

• NumPy

• Matplotlib

• h5py

• A potential energy surface (PES) for a system of interest, which can be called using a Python function (See Documentation).

• Optional: MPI4Py (for multi-node PES evaluation, otherwise uses multiprocessing for multi-core PES evaluation)

• Optional: Tensorflow (for Neural Network PES)

• Tutorial: A compiler required for the potential energy surface (the tutorial potential uses gfortran)

• Tutorial: make (on Linux systems, this is usually installed via the 'build-essential' or 'Development Tools' packages )
