This is the official implementation of MolCLR: ["Molecular Contrastive Learning of Representations via Graph Neural Networks"](https://www.nature.com/articles/s42256-022-00447-x). In this work, we introduce a contrastive learning framework for molecular representation learning on large unlabelled dataset (~10M unique molecules). MolCLR pre-training greatly boosts the performance of GNN models on various downstream molecular property prediction benchmarks.

## Getting Started
### Installation
Set up conda environment and clone the github repo
```
# create a new environment
$ conda create --name molclr python=3.7
$ conda activate molclr
# install requirements
$ pip install torch==1.7.1+cu110 torchvision==0.8.2+cu110 -f https://download.pytorch.org/whl/torch_stable.html
$ pip install torch-geometric==1.6.3 torch-sparse==0.6.9 torch-scatter==2.0.6 -f https://pytorch-geometric.com/whl/torch-1.7.0+cu110.html
$ pip install PyYAML
$ conda install -c conda-forge rdkit=2020.09.1.0
$ conda install -c conda-forge tensorboard
$ conda install -c conda-forge nvidia-apex # optional
# clone the source code of MolCLR
$ git clone https://github.com/yuyangw/MolCLR.git
$ cd MolCLR
```
### Dataset
You can download the pre-training data and benchmarks used in the paper [here](https://drive.google.com/file/d/1aDtN6Qqddwwn2x612kWz9g0xQcuAtzDE/view?usp=sharing) and extract the zip file under `./data` folder. The data for pre-training can be found in `pubchem-10m-clean.txt`. All the databases for fine-tuning are saved in the folder under the benchmark name. You can also find the benchmarks from [MoleculeNet](https://moleculenet.org/).
### Pre-training
To train the MolCLR, where the configurations and detailed explaination for each variable can be found in `config.yaml`
```
$ python molclr.py
```
To monitor the training via tensorboard, run `tensorboard --logdir ckpt/{PATH}` and click the URL http://127.0.0.1:6006/.
### Fine-tuning
To fine-tune the MolCLR pre-trained model on downstream molecular benchmarks, where the configurations and detailed explaination for each variable can be found in `config_finetune.yaml`
```
$ python finetune.py
```
### Pre-trained models
We also provide pre-trained GCN and GIN models, which can be found in `ckpt/pretrained_gin` and `ckpt/pretrained_gcn` respectively.
