Benchmarking

Benchmarking on SWE-bench

This page talks about benchmarking on SWE-bench to measure the software engineering capabilities of SWE-agent. Benchmarking for the other modes (programming challenges, cybersecurity) are coming soon.

There are two steps to the SWE-agent/SWE-bench pipeline. First SWE-agent takes an input GitHub issue and returns a pull request that attempts to fix it. We call that step inference. The second step (currently only available for issues in the SWE-bench benchmark) is to evaluate the pull request to verify that it has indeed fixed the issue.

Architectures

At this moment, there are known issues with a small number of repositories that don't install properly for arm64 / aarch64 architecture computers. We're working on a fix, but if you'd like to run and evaluate on the entirety of SWE-bench, the easiest way is by using an x86 machine.

👩‍💻 Inference

Run SWE-agent on SWE-bench Lite and generate patches.

python run.py --model_name gpt4 \
  --per_instance_cost_limit 2.00 \
  --config_file ./config/default.yaml

If you'd like to run on a single issue from SWE-bench, use the --instance_filter option as follows: 

python run.py --model_name gpt4 \
  --instance_filter marshmallow-code__marshmallow-1359

The above examples use the default value of --data_path (princeton-nlp/SWE-bench_Lite, which will be looked up from huggingface). You can specify any other huggingface datasets as well, or supply the path to a pre-downloaded dataset. By default, SWE-agent evaluates on the dev split of that dataset. You can change that by supplying the --split argument to the above commands (obviously you shouldn't tune your model on the test dataset).

🧪 Evaluation

Previous evaluation/ scripts

We have removed the scripts that were previously in the evaluation/ subfolder. They were relatively thin wrappers around swe-bench. After the swe-bench 2.0 update, we recommend to use swe-bench directly.

You can directly run SWE-bench to evaluate the SWE-agent results.

After installing SWE-bench, you can run run_evaluation as such:

python -m swebench.harness.run_evaluation \
    --predictions_path /path/to/all_preds.jsonl \
    --max_workers 1 \
    --run_id test \
    --split dev

Head over to SWE-bench for details.

Default split

When running swe-agent it uses the SWE-bench lite dev split by default (i.e., when not specifying --data_path or --split). However, swe-bench assumes the SWE-bench lite test split by default. When you get warnings from swe-bench about missing instances, make sure you specify --split test or --split dev appropriately.
