HuggingFace 🤗

The models and dataset are both also available on the HF Hub.

To replicate the experimental setup of the paper follow the following steps:

Docker Image

It is recommended to use the provided Docker image, which has the correct Cuda version and all of the required dependencies installed. Pull the image, create a container, and mount this folder as a volume:

docker pull aalkaswan/bint5
docker run -i -t --name {containerName} --gpus all -v $(pwd):/data aalkaswan/bint5 /bin/bash

This should spawn a shell, which allows you to use the container. Change to the mounted volume:

cd /data/

All of the following commands should then be run from within the Docker container. You can respawn the shell using:

docker exec -it {containerName} /bin/bash

If you wish to run without using docker, we also provide a requirements.txt file.

Setup

First, clone the CodeT5 repo into this directory:

git clone https://github.com/salesforce/CodeT5.git

Run the following command to set the correct working directory in the training script:

wdir=\WORKDIR=\"`pwd`/'CodeT5/CodeT5'\" && sed -i '1 s#^.*$#'$wdir'#' CodeT5/CodeT5/sh/exp_with_args.sh

Now that the model is set up we need to download the data, use the following commands to download and unpack the data:

wget https://zenodo.org/record/7229809/files/Capybara.zip
unzip Capybara.zip
rm Capybara.zip

Similarly to download the pretrained BinT5 checkpoints:

wget https://zenodo.org/records/7229913/files/BinT5.zip?download=1
unzip BinT5.zip
rm Capybara.zip

Finetune Models

To use this data in BinT5, setup the data folders in the CodeT5 project:

mkdir -p CodeT5/CodeT5/data/summarize/{C,decomC,demiStripped,strippedDecomC}

Now you can simply move the data of your choice from \Capybara\training_data\{lan}\{dup/dedup} to CodeT5\data\summarize\{lan}. In the downloaded CodeT5 repo change this line and add the languages to the subtask list. Finally, edit the language variable in the job.sh file and start training in detached mode:

docker exec -d {containerName} /bin/bash "/data/job.sh"

You can view the progress and results of the finetuning in the: \CodeT5\sh\log.txt file, the resulting model and training outputs are also present in the same folder.

Use Finetuned BinT5 Checkpoints

For each of the models, a pytorch.bin file is provided in its respective folder. These models can be loaded into CodeT5 and used for inference or further training.

To utilise the models, download the reference CodeT5-base model from HuggingFace: bash

GIT_LFS_SKIP_SMUDGE=1 git clone https://huggingface.co/Salesforce/codet5-base

• This will pull the repo but skip the pytorch_model.bin file, which will be replaced in the next step.
• Select the model that you wish to use from the respective directory. Copy this file and replace the pytorch_model.bin in the local codet5-base directory downloaded in the previous step.
• Instead of loading in the model through HuggingFace, load in a local model. To load a local model, change line 66 in the sh/exp_with_args.sh file to the path of your local codet5-base model which you downloaded and configured in the previous step. The tokenizer does not need to be replaced.
• The model can now be run by executing sh/run_exp.py
