The official implementation of dual-view molecule pre-training.

Dual-view molecule pre-training

This repository contains the code for Dual-view Molecule Pre-training. We implement our method based on the codebase of fairseq.

Requirements and Installation

• PyTorch version == 1.8.0
• PyTorch Geometric version == 1.6.3
• RDKit version == 2020.09.5

You can build the Dockerfile or use the docker image teslazhu/pretrainmol36:latest.

To install the code from source

git clone https://github.com/microsoft/DVMP
cd DVMP
pwd=$PWD

git clone [email protected]:pytorch/fairseq.git /tmp/fairseq
cp dvmp.patch /tmp/fairseq
cd /tmp/fairseq
git checkout aa5f0119a383e013e56ae5d88e4a7aff0e67f0f9
git apply dvmp.patch

cd $pwd
cp -r /tmp/fairseq/* ./

pip install -e . 

Getting Started

Pre-training

Data Preprocessing

DATADIR=/yourdatadir

# Canonicalize all SMILES
python molecule/canonicalize.py $DATADIR/train.smi --workers 30

# Tokenize all SMILES
python molecule/tokenize_re.py $DATADIR/train.smi.can --workers 30 \
  --output-fn $DATADIR/train.bpe 

# You also should canonicalize and tokenize the dev set.

# Binarize the data
fairseq-preprocess \
    --only-source \
    --trainpref $DATADIR/train.bpe \
    --validpref $DATADIR/valid.bpe \
    --destdir /data/pubchem \
    --workers 30 --srcdict molecule/dict.txt \

About the checkpoing

Hello, I am very glad to learn about your work. In my work, SMILE information of coded drugs is needed. Could you please share it with your pre-trained checkpoint? Looking forward to your reply!

Why it raise FileNotFoundError("PyG data {} not found.".format(prefix))?

Hello, I have a question about the Pre-training process. When I try to run fairseq-train.py, why it says FileNotFoundError("PyG data {} not found.".format(prefix))? Where can I get the PyG data ? Thank you.
