BioGPT

This repository contains the implementation of BioGPT: Generative Pre-trained Transformer for Biomedical Text Generation and Mining, by Renqian Luo, Liai Sun, Yingce Xia, Tao Qin, Sheng Zhang, Hoifung Poon and Tie-Yan Liu.

Requirements and Installation

• PyTorch version >= 1.8.0
• Python version >= 3.7
• fairseq:

git clone https://github.com/pytorch/fairseq
cd fairseq
git checkout dd7499
pip install .

• Moses

git clone https://github.com/moses-smt/mosesdecoder.git
export MOSES=${PWD}/mosesdecoder

• fastBPE

pip install fastBPE
git clone https://github.com/glample/fastBPE.git
export FASTBPE=${PWD}/fastBPE
cd fastBPE
g++ -std=c++11 -pthread -O3 fastBPE/main.cc -IfastBPE -o fast

• sacremoses

pip install sacremoses

• sklearn

pip install sklearn

Remember to set the environment variables MOSES and FASTBPE to the path of Moses and fastBPE respetively, as they will be required later.

Getting Started

Pre-trained models

We provide our pre-trained BioGPT model checkpoint along with fine-tuned checkpoints for downstream tasks here. Download it and extract it the root of this project.

wget https://msralaphilly2.blob.core.windows.net/ml-la/release/BioGPT/checkpoints.tgz
tar -zxvf checkpoints.tgz

It contains following folders:

• Pre-trained-BioGPT: The pre-trained BioGPT model checkpoint
• RE-BC5CDR-BioGPT: The fine-tuned checkpoint for relation extraction task on BC5CDR
• RE-DTI-BioGPT: The fine-tuned checkpoint for relation extraction task on KD-DTI
• RE-DDI-BioGPT: The fine-tuned checkpoint for relation extraction task on DDI
• DC-HoC-BioGPT: The fine-tuned checkpoint for document classification task on HoC
• QA-PubMedQA-BioGPT: The fine-tuned checkpoint for question answering task on PubMedQA

Example Usage

Use pre-trained BioGPT model in your code:

import torch
from fairseq.models.transformer_lm import TransformerLanguageModel
m = TransformerLanguageModel.from_pretrained(
        "checkpoints/Pre-trained-BioGPT", 
        "checkpoint.pt", 
        "data/PubMed/data-bin",
        tokenizer='moses', 
        bpe='fastbpe', 
        bpe_codes="data/bpecodes",
        min_len=100,
        max_len_b=1024)
m.cuda()
src_tokens = m.encode("COVID-19 is")
generate = m.generate([src_tokens], beam=)[0]
output = m.decode(generate[0]["tokens"])
print(output)

Use fine-tuned BioGPT model on KD-DTI for drug-target-interaction in your code:

import torch
from fairseq.models.transformer_lm import TransformerLanguageModel
m = TransformerLanguageModel.from_pretrained(
        "checkpoints/RE-DTI-BioGPT", 
        "checkpoint_avg.pt", 
        "data/KD-DTI/relis-bin",
        tokenizer='moses', 
        bpe='fastbpe', 
        bpe_codes="data/bpecodes",
        max_len_b=1024,
        beam=1)
m.cuda()
src_text="" # input text, e.g., a PubMed abstract
src_tokens = m.encode(src_text)
generate = m.generate([src_tokens], beam=args.beam)[0]
output = m.decode(generate[0]["tokens"])
print(output)
