## Requirements

- Uncompress the CrossCodeEval data via `tar -xvJf data/crosscodeeval_data.tar.xz -C data/`
    - The data contains {baseline, retrieval, retrieval w/ ref.} setting x {bm25, UniXCoder, OpenAI Ada} retriever.
    - **Please [email us](mailto:y.robin.ding@gmail.com) if you need the raw data.**
- Install dependencies via `pip install -r requirements.txt`
- Build tree sitter via `bash scripts/build_treesitter.sh`
