MESS is primarily motivated by the need to demystify the underpinnings of electronic structure simulations. The target audience is the collective molecular machine learning community. We identify this community as anyone working towards accelerating our understanding of atomistic processes by combining physical models (e.g. density functional theory) with methods that learn from data (e.g. deep neural networks).
Calculate the ground state energy of a single water molecule using the 6-31g basis set and the local density approximation (LDA):
from mess import Hamiltonian, basisset, minimise, molecule
mol = molecule("water")
basis = basisset(mol, basis_name="6-31g")
H = Hamiltonian(basis, xc_method="lda")
E, C, sol = minimise(H)

We recommend installing directly from the main branch from github and sharing any feedback as issues.
pip install git+https://github.com/graphcore-research/mess.git
Requires Python 3.10+ and we recommend installing JAX for your target system (e.g. CPU, GPU, etc).
