👋 Overview

SWE-bench is a benchmark for evaluating large language models on real world software issues collected from GitHub. Given a codebase and an issue, a language model is tasked with generating a patch that resolves the described problem.

To access SWE-bench, copy and run the following code:

from datasets import load_dataset
swebench = load_dataset('princeton-nlp/SWE-bench', split='test')

🚀 Set Up

SWE-bench uses Docker for reproducible evaluations. Follow the instructions in the Docker setup guide to install Docker on your machine. If you're setting up on Linux, we recommend seeing the post-installation steps as well.

Finally, to build SWE-bench from source, follow these steps:

git clone [email protected]:princeton-nlp/SWE-bench.git
cd SWE-bench
pip install -e .

Test your installation by running:

python -m swebench.harness.run_evaluation \
    --predictions_path gold \
    --max_workers 1 \
    --instance_ids sympy__sympy-20590 \
    --run_id validate-gold

💽 Usage

Warning

Running fast evaluations on SWE-bench can be resource intensive We recommend running the evaluation harness on an x86_64 machine with at least 120GB of free storage, 16GB of RAM, and 8 CPU cores. You may need to experiment with the --max_workers argument to find the optimal number of workers for your machine, but we recommend using fewer than min(0.75 * os.cpu_count(), 24).

If running with docker desktop, make sure to increase your virtual disk space to have ~120 free GB available, and set max_workers to be consistent with the above for the CPUs available to docker.

Support for arm64 machines is experimental.

Evaluate model predictions on SWE-bench Lite using the evaluation harness with the following command:

python -m swebench.harness.run_evaluation \
    --dataset_name princeton-nlp/SWE-bench_Lite \
    --predictions_path <path_to_predictions> \
    --max_workers <num_workers> \
    --run_id <run_id>
    # use --predictions_path 'gold' to verify the gold patches
    # use --run_id to name the evaluation run

This command will generate docker build logs (build_image_logs) and evaluation logs (run_instance_logs) in the current directory.

The final evaluation results will be stored in the evaluation_results directory.

To see the full list of arguments for the evaluation harness, run:

python -m swebench.harness.run_evaluation --help

Additionally, the SWE-Bench repo can help you:

• Train your own models on our pre-processed datasets
• Run inference on existing models (either models you have on-disk like LLaMA, or models you have access to through an API like GPT-4). The inference step is where you get a repo and an issue and have the model try to generate a fix for it.
• Run SWE-bench's data collection procedure on your own repositories, to make new SWE-Bench tasks.
