Requirements

Tested combination: Python 3.9.6 + PyTorch 1.11.0

Other required python libraries include: numpy, scikit-learn, optuna, torch_geometric, etc.

Prepare Data

We write a script for preparing datasets.

python prepare_dataset.py

Reproduce Results on MD17

To reproduce results of the benzene molecule.

python main_md17.py --dataset benzene --test 

"benzene" can be replaced with other molecules: benzene, uracil, naphthalene, aspirin, salicylic_acid, malonaldehyde, ethanol, toluene

To do ablation analysis.

NoDir2

python main_md17.py --nodir2 --dataset benzene --test 

NoDir3

python main_md17.py --nodir3 --dataset benzene --test 

Global

python main_md17.py --global_frame --dataset benzene --test 

NoDecomp

python main_md17.py --no_filter_decomp --dataset benzene --test 

NoShare

python main_md17.py --no_share_filter --dataset benzene --test 

Reproduce Results on QM9

To reproduce results of the homo target

python main_qm9.py --dataset homo --test

"homo" can be replaced with other targets: dipole_moment, isotropic_polarizability, homo, lumo, gap, electronic_spatial_extent, zpve, energy_U0, energy_U, enthalpy_H, free_energy, heat_capacity
