DiscoGNN

This is a Pytorch implementation of the DiscoGNN paper:

Installation

We used the following Python packages for core development. We tested on Python 3.7.

pytorch                   1.0.1
torch-cluster             1.2.4              
torch-geometric           1.0.3
torch-scatter             1.1.2 
torch-sparse              0.2.4
torch-spline-conv         1.0.6
rdkit                     2019.03.1.0
tqdm                      4.31.1
tensorboardx              1.6

Dataset download

All the necessary data files can be downloaded from the following links.

For the chemistry dataset, download from chem data (2.5GB), unzip it, and put it under dataset/.

Pre-training and fine-tuning

1. Self-supervised pre-training

python pretrain_disco.py --output_model_file OUTPUT_MODEL_PATH

This will save the resulting pre-trained model to OUTPUT_MODEL_PATH.

2. Fine-tuning

python finetune.py --input_model_file INPUT_MODEL_PATH --dataset DOWNSTREAM_DATASET --filename OUTPUT_FILE_PATH

This will finetune pre-trained model specified in INPUT_MODEL_PATH using dataset DOWNSTREAM_DATASET. The result of fine-tuning will be saved to OUTPUT_FILE_PATH.

Reproducing results in the paper

Our results in the paper can be reproduced using a random seed ranging from 0 to 9 with scaffold splitting.
