BiomedGPT: A Unified and Generalist Biomedical Generative Pre-trained Transformer for Vision, Language, and Multimodal Tasks

BiomedGPT

BiomedGPT is developed based on OFA but pre-trained and fine-tuned with multi-modal & multi-task biomedical datasets. Details are shown in datasets.md. Feel free to contact us or post issues.

Please kindly note that this repository is still a work in progress.

• June 9: release pre-trained checkpoints; release the data preprocessing and fine-tuning codes for VQA and Captioning.
• June 12: release the data preprocessing and fine-tuning codes for NLI and text summarization.
• June 15: release the data preprocessing and fine-tuning codes for image classification.
• June 26: release data preprocessing scripts and codes for pretraining.
  
  

Checkpoints

We provid pretrained checkpoints of BiomedGPT (Dropbox), which can be put in the scripts/ folder for further development. For finetuned checkpoints, please refer to checkpoints.md.

Note:

I recently received a reminder regarding potential policy issues associated with releasing the model checkpoints, due to the fact that not all pretraining / downstream datasets are fully open-sourced. I need to review the relevant policies and licenses to ensure the legality of sharing the weights. Once I can confirm this, I will enable downloading the checkpoints. Thank you for your patience.

Installation

git clone https://github.com/taokz/BiomedGPT
conda env create -f biomedgpt.yml
python -m pip install pip==21.2.4
pip install fairseq

Implementation

We provide the preprocessing, pretraining, finetuning and inference scripts in the scripts/ folder. You can follow the directory setting below:

BiomedGPT/
├── checkpoints/
├── datasets/
│   ├── pretraining/
│   ├── finetuning/
│   └── ...
├── scripts/
│   ├── preprocess/
│   │   ├── pretraining/
│   │   └── finetuning/
│   ├── pretrain/
│   ├── vqa/
│   └── ...
└── ...

Pretraining

Please follow datasets.md to prepare pretraining datasets, which includes 4 TSV files: vision_language.tsv, text.tsv, image.tsv and detection.tsv in the directory of ./datasets/pretraining/.

cd scripts/pretrain
bash pretrain_tiny.sh

Feel free to modify the hyperparameters in the bash script for your requirements or ablation study.

Downstreams

We provide the run scripts of fine-tuning and inference. There will be log files during execution. Before fine-tuning or inference, please refer to

# for fine-tuning
bash train_peir_gross.sh
# for inference
bash evaluate_peir_gross.sh

Text Summarization

Image Classification

cd scripts/image_cls
# for fine-tuning: I provide a template, please set different hyparameters for each dataset in MedMNIST if required.
bash train_medmnist.sh 
# for inference: a template
bash evaluate_medmnist.sh
