NFFLr (Introduction)

The Neural Force Field Learning library (docs) is intended to be a flexible toolkit for developing and deploying atomistic machine learning systems, with a particular focus on crystalline material property and energy models.

The initial codebase is a fork of ALIGNN, with modified configuration and modeling interfaces for performance.

Installation

We recommend using a per-project pyenv-virtualenv or conda environment.

To ensure proper CUDA support, make sure to install the GPU versions of PyTorch and DGL. For example, to set up a conda environment on linux with with python 3.10 and CUDA 12.1:

conda create --name myproject python=3.10
conda activate myproject
conda install pytorch torchvision torchaudio pytorch-cuda=12.1 -c pytorch -c nvidia
conda install -c dglteam/label/cu121 dgl
python -m pip install nfflr

Examples
