HydraGNN

Distributed PyTorch implementation of multi-headed graph convolutional neural networks

Dependencies

To install required packages with only basic capability (torch, torch_geometric, and related packages) and to serialize+store the processed data for later sessions (pickle5):

pip install -r requirements.txt
pip install -r requirements-torchdep.txt

If you plan to modify the code, include packages for formatting (black) and testing (pytest) the code:

pip install -r requirements-dev.txt

Detailed dependency installation instructions are available on the Wiki

Installation

After checking out HydgraGNN, we recommend to install HydraGNN in a developer mode so that you can use the files in your current location and update them if needed:

python -m pip install -e .

Or, simply type the following in the HydraGNN directory:

export PYTHONPATH=$PWD:$PYTHONPATH

Alternatively, if you have no plane to update, you can install HydraGNN in your python tree as a static package:

python setup.py install

Running the code

There are two main options for running the code; both require a JSON input file for configurable options.

1. Training a model, including continuing from a previously trained model using configuration options:

import hydragnn
hydragnn.run_training("examples/configuration.json")

2. Making predictions from a previously trained model:

import hydragnn
hydragnn.run_prediction("examples/configuration.json", model)

Datasets

Built in examples are provided for testing purposes only. One source of data to create HydraGNN surrogate predictions is DFT output on the OLCF Constellation: https://doi.ccs.ornl.gov/

Detailed instructions are available on the Wiki

Configurable settings

HydraGNN uses a JSON configuration file (examples in examples/):

There are many options for HydraGNN; the dataset and model type are particularly important:

• ["Verbosity"]["level"]: 0, 1, 2, 3, 4
• ["Dataset"]["name"]: CuAu_32atoms, FePt_32atoms, FeSi_1024atoms
• ["NeuralNetwork"]["Architecture"]["model_type"]: PNA, MFC, GIN, GAT, CGCNN, SchNet, DimeNet, EGNN
