This repository provides the source code for 'Adaptive 3D Pre-Training for Molecular Property Prediction'. 3D PGT aims to use geometric information to design pre-training tasks to enhance the property prediction tasks of downstream 2D molecular graphs. The whole process consists of two stages：

• In the 3D pre-training stage, 3D PGT performs several generative pre-training tasks on the dataset containing 3D information
• In the finetune stage, 3D PGT fine-tunes the pre-trained model on molecular datasets containing only 2D topological structures and performs property prediction tasks

For dataset preprocessing in GEOM, please use the following commands:

python GEOM_dataset_preparation.py -n_mol $N_MOL --n_upper $N_UPPER --data_folder $ SLURM_TMPDIR

For PCQM4Mv2 dataset, it is a recently published dataset for the OGB Large Scale Challenge built to aide the development of state-of-the-art machine learning models for molecular property prediction. The task is for the quantum chemistry task of predicting the HOMO-LUMO energy gap of a molecule.

You can implement adaptive 3D pre-training by running the following code:

# Running 3D PGT for pre-training on GEOM dataset
python pretrain_main.py --cfg configs/GPS/pre-train_Drugs.yaml wandb.use False

# Running 3D PGT for pre-training on PCQM4Mv2 dataset
python pretrain_main.py --cfg configs/GPS/pcqm4m-GPS.yaml wandb.use False

You can use the following code to finetune downstream tasks, but pay attention to setting the addresses of downstream task datasets and pre-trained model files in the config file.

Running 3D PGT for finetuning on GEOM-Drugs dataset
python main.py --cfg configs/GPS/finetune_Drugs.yaml
