1. Dependencies

Python == 3.8
PyTorch == 1.8.0
transformers == 3.4.0
torch-geometric == 1.7.0

Run the following commands to create a conda environment (assuming CUDA 10.1):

conda create -y -n greaselm python=3.8
conda activate greaselm
pip install numpy==1.18.3 tqdm
pip install torch==1.8.0+cu101 torchvision -f https://download.pytorch.org/whl/torch_stable.html
pip install transformers==3.4.0 nltk spacy
pip install wandb
conda install -y -c conda-forge tensorboardx
conda install -y -c conda-forge tensorboard

# for torch-geometric
pip install torch-scatter==2.0.7 -f https://pytorch-geometric.com/whl/torch-1.8.0+cu101.html
pip install torch-cluster==1.5.9 -f https://pytorch-geometric.com/whl/torch-1.8.0+cu101.html

pip install torch-geometric==1.7.0 -f https://pytorch-geometric.com/whl/torch-1.8.0+cu101.html

2. Download data

Download and preprocess data yourself

Preprocessing the data yourself may take long, so if you want to directly download preprocessed data, please jump to the next subsection.

Download the raw ConceptNet, CommonsenseQA, OpenBookQA data by using

./download_raw_data.sh

You can preprocess these raw data by running

CUDA_VISIBLE_DEVICES=0 python preprocess.py -p <num_processes>

You can specify the GPU you want to use in the beginning of the command CUDA_VISIBLE_DEVICES=.... The script will:

Setup ConceptNet (e.g., extract English relations from ConceptNet, merge the original 42 relation types into 17 types)
Convert the QA datasets into .jsonl files (e.g., stored in data/csqa/statement/)
Identify all mentioned concepts in the questions and answers
Extract subgraphs for each q-a pair

The script to download and preprocess the MedQA-USMLE data and the biomedical knowledge graph based on Disease Database and DrugBank is provided in utils_biomed/.

Directly download preprocessed data

For your convenience, if you don't want to preprocess the data yourself, you can download all the preprocessed data here. Download them into the top-level directory of this repo and unzip them. Move the medqa_usmle and ddb folders into the data/ directory.

Resulting file structure

The resulting file structure should look like this:

.
├── README.md
├── data/
    ├── cpnet/                 (prerocessed ConceptNet)
    ├── csqa/
        ├── train_rand_split.jsonl
        ├── dev_rand_split.jsonl
        ├── test_rand_split_no_answers.jsonl
        ├── statement/             (converted statements)
        ├── grounded/              (grounded entities)
        ├── graphs/                (extracted subgraphs)
        ├── ...
    ├── obqa/
    ├── medqa_usmle/
    └── ddb/

3. Training GreaseLM

To train GreaseLM on CommonsenseQA, run

CUDA_VISIBLE_DEVICES=0 ./run_greaselm.sh csqa --data_dir data/

You can specify up to 2 GPUs you want to use in the beginning of the command CUDA_VISIBLE_DEVICES=....

Similarly, to train GreaseLM on OpenbookQA, run

CUDA_VISIBLE_DEVICES=0 ./run_greaselm.sh obqa --data_dir data/

To train GreaseLM on MedQA-USMLE, run

CUDA_VISIBLE_DEVICES=0 ./run_greaselm__medqa_usmle.sh

4. Pretrained model checkpoints

You can download a pretrained GreaseLM model on CommonsenseQA here, which achieves an IH-dev acc. of 79.0 and an IH-test acc. of 74.0.

You can also download a pretrained GreaseLM model on OpenbookQA here, which achieves an test acc. of 84.8.

You can also download a pretrained GreaseLM model on MedQA-USMLE here, which achieves an test acc. of 38.5.

5. Evaluating a pretrained model checkpoint

To evaluate a pretrained GreaseLM model checkpoint on CommonsenseQA, run

CUDA_VISIBLE_DEVICES=0 ./eval_greaselm.sh csqa --data_dir data/ --load_model_path /path/to/checkpoint

Again you can specify up to 2 GPUs you want to use in the beginning of the command CUDA_VISIBLE_DEVICES=....

Similarly, to evaluate a pretrained GreaseLM model checkpoint on OpenbookQA, run

CUDA_VISIBLE_DEVICES=0 ./eval_greaselm.sh obqa --data_dir data/ --load_model_path /path/to/checkpoint

To evaluate a pretrained GreaseLM model checkpoint on MedQA-USMLE, run

INHERIT_BERT=1 CUDA_VISIBLE_DEVICES=0 ./eval_greaselm.sh medqa_usmle --data_dir data/ --load_model_path /path/to/checkpoint

6. Use your own dataset

Convert your dataset to {train,dev,test}.statement.jsonl in .jsonl format (see data/csqa/statement/train.statement.jsonl)
Create a directory in data/{yourdataset}/ to store the .jsonl files
Modify preprocess.py and perform subgraph extraction for your data
Modify utils/parser_utils.py to support your own dataset
