About

BigCodeBench

BigCodeBench is an easy-to-use benchmark for code generation with practical and challenging programming tasks. It aims to evaluate the true programming capabilities of large language models (LLMs) in a more realistic setting. The benchmark is designed for HumanEval-like function-level code generation tasks, but with much more complex instructions and diverse function calls. To facilitate the evaluation of LLMs on BigCodeBench, we provide this Python package bigcodebench that includes the dataset, generation scripts, and evaluation scripts. The package is built on top of the EvalPlus framework, which is a flexible and extensible evaluation framework for code generation tasks.

Why BigCodeBench?

BigCodeBench focuses on the evaluation of LLM4Code with diverse function calls and complex instruction, with:

• ✨ Precise evaluation & ranking: See our leaderboard for latest LLM rankings before & after rigorous evaluation.
• ✨ Pre-generated samples: BigCodeBench accelerates code intelligence research by open-sourcing LLM-generated samples for various models -- no need to re-run the expensive benchmarks!

Main Differences from EvalPlus

We inherit the design of the EvalPlus framework, which is a flexible and extensible evaluation framework for code generation tasks. However, BigCodeBench has the following differences:

• Execution Environment: The execution environment in BigCodeBench is less bounded than EvalPlus to support tasks with diverse library dependencies.
• Test Evaluation: BigCodeBench relies on unittest for evaluating the generated code, which is more suitable for the test harness in BigCodeBench.

🔥 Quick Start

Tip

BigCodeBench ❤️ bigcode-evaluation-harness! BigCodeBench will be integrated to bigcode-evaluation-harness, and you can also run it there!

To get started, please first set up the environment:

# Install to use bigcodebench.evaluate
pip install bigcodebench --upgrade
# If you want to use the evaluate locally, you need to install the requirements
pip install -I -r https://raw.githubusercontent.com/bigcode-project/bigcodebench/main/Requirements/requirements-eval.txt

# Install to use bigcodebench.generate
# You are strongly recommended to install the generate dependencies in a separate environment
pip install bigcodebench[generate] --upgrade

⏬ Install nightly version :: click to expand ::

# Install to use bigcodebench.evaluate
pip install "git+https://github.com/bigcode-project/bigcodebench.git" --upgrade

⏬ Using BigCodeBench as a local repo? :: click to expand ::

git clone https://github.com/bigcode-project/bigcodebench.git
cd bigcodebench
export PYTHONPATH=$PYTHONPATH:$(pwd)
# Install to use bigcodebench.evaluate
pip install -e .
# Install to use bigcodebench.generate
pip install -e .[generate]

Code Generation

You are suggested to use flash-attn for generating code samples.

pip install -U flash-attn

To generate code samples from a model, you can use the following command:

bigcodebench.generate \
    --model [model_name] \
    --subset [complete|instruct] \
    --greedy \
    --bs [bs] \
    --temperature [temp] \
    --n_samples [n_samples] \
    --resume \
    --backend [vllm|hf|openai|mistral|anthropic|google] \
    --tp [gpu_number] \
    [--trust_remote_code] \
    [--base_url [base_url]]

The generated code samples will be stored in a file named [model_name]--bigcodebench-[instruct|complete]--[backend]-[temp]-[n_samples].jsonl. Alternatively, you can use the following command to utilize our pre-built docker images for generating code samples:

# If you are using GPUs
docker run --gpus '"device=$CUDA_VISIBLE_DEVICES"' -v $(pwd):/app -t bigcodebench/bigcodebench-generate:latest \
    --model [model_name] \ 
    --subset [complete|instruct] \
    [--greedy] \
    --bs [bs] \   
    --temperature [temp] \
    --n_samples [n_samples] \
    --resume \
    --backend [vllm|hf|openai|mistral|anthropic|google] \
    --tp [gpu_number]

# ...Or if you are using CPUs
docker run -v $(pwd):/app -t bigcodebench/bigcodebench-generate:latest \
    --model [model_name] \ 
    --subset [complete|instruct] \
    [--greedy] \
    --bs [bs] \   
    --temperature [temp] \
    --n_samples [n_samples] \
    --resume \
    --backend [vllm|hf|openai|mistral|anthropic|google]

# If you wish to use gated or private HuggingFace models and datasets
docker run -e HUGGING_FACE_HUB_TOKEN=$token -v $(pwd):/app -t bigcodebench/bigcodebench-generate:latest # omit other arguments4

# Similarly, to use other backends that require authentication
docker run -e OPENAI_API_KEY=$OPENAI_API_KEY -v $(pwd):/app -t bigcodebench/bigcodebench-generate:latest # omit other arguments
docker run -e GOOGLE_API_KEY=$OPENAI_API_KEY -v $(pwd):/app -t bigcodebench/bigcodebench-generate:latest # omit other arguments
docker run -e ANTHROPIC_KEY=$ANTHROPIC_KEY -v $(pwd):/app -t bigcodebench/bigcodebench-generate:latest # omit other arguments

Following which, you can run the built container as shown in above.

🤔 Structure of `problem`? :: click to expand ::

• task_id is the identifier string for the task
• entry_point is the name of the function
• complete_prompt is the prompt for BigCodeBench-Complete
• instruct_prompt is the prompt for BigCodeBench-Instruct

• canonical_solution is the ground-truth implementation
• test is the unittest.TestCase class

Note

Expected Schema of [model_name]--bigcodebench-[task]--[backend]-[temp]-[n_samples].jsonl

1. task_id: Task ID, which are the keys of get_bigcodebench()
2. solution (optional): Self-contained solution (usually including the prompt)
   • Example: {"task_id": "BigCodeBench/?", "solution": "def f():\n return 1"}

Code Post-processing

LLM-generated text may not be compilable code for including natural language lines or incomplete extra code. We provide a tool namely bigcodebench.sanitize to clean up the code:

# 💡 If you want to get the calibrated results:
bigcodebench.sanitize --samples samples.jsonl --calibrate
# Sanitized code will be produced to `samples-sanitized-calibrated.jsonl`

# 💡 If you want to get the original results:
bigcodebench.sanitize --samples samples.jsonl
# Sanitized code will be produced to `samples-sanitized.jsonl`

# 💡 If you are storing codes in directories:
bigcodebench.sanitize --samples /path/to/vicuna-[??]b_temp_[??]
# Sanitized code will be produced to `/path/to/vicuna-[??]b_temp_[??]-sanitized`

If you want to use the pre-built docker images for post-processing, you can use the following command:

# Change the entrypoint to bigcodebench.sanitize in any pre-built docker image, like bigcodebench/bigcodebench-evaluate:latest
docker run -it --entrypoint bigcodebench.sanitize -v $(pwd):/app bigcodebench/bigcodebench-evaluate:latest --samples samples.jsonl

🔎 Checking the compatibility of post-processed code:: click to expand ::

To double-check the post-processing results, you can use bigcodebench.syncheck to check the code validity before and after sanitization, which will print erroneous code snippets and why they are wrong:

# 💡 If you are storing codes in jsonl:
bigcodebench.syncheck --samples samples.jsonl

# 💡 If you are storing codes in directories:
bigcodebench.syncheck --samples /path/to/vicuna-[??]b_temp_[??]

# 💡 Or change the entrypoint to bigcodebench.syncheck in any pre-built docker image, like 
docker run -it --entrypoint bigcodebench.syncheck -v $(pwd):/app bigcodebench/bigcodebench-evaluate:latest --samples samples.jsonl

Code Evaluation

You are strongly recommended to use a sandbox such as docker:

# Mount the current directory to the container
# If you want to change the RAM address space limit (in MB, 128 GB by default): `--max-as-limit XXX`
# If you want to change the RAM data segment limit (in MB, 4 GB by default): `--max-data-limit`
# If you want to change the RAM stack limit (in MB, 4 MB by default): `--max-stack-limit`
docker run -v $(pwd):/app bigcodebench/bigcodebench-evaluate:latest --subset [complete|instruct] --samples samples-sanitized-calibrated.jsonl

# If you only want to check the ground truths
docker run -v $(pwd):/app bigcodebench/bigcodebench-evaluate:latest --subset [complete|instruct] --samples samples-sanitized-calibrated.jsonl --check-gt-only

...Or if you want to try it locally regardless of the risks ⚠️:

First, install the dependencies for BigCodeBench:

pip install -r https://raw.githubusercontent.com/bigcode-project/bigcodebench/main/Requirements/requirements-eval.txt

Then, run the evaluation:

# ...Or locally ⚠️
bigcodebench.evaluate --subset [complete|instruct] --samples samples-sanitized-calibrated.jsonl
# ...If you really don't want to check the ground truths
bigcodebench.evaluate --subset [complete|instruct] --samples samples-sanitized-calibrated.jsonl --no-gt

Tip

Do you use a very slow machine?

LLM solutions are regarded as failed on timeout (and OOM etc.). Specifically, we set the dynamic timeout based on the ground-truth solution's runtime.

Additionally, you are NOT encouraged to make your test-bed over stressed while running evaluation. For example, using --parallel 64 on a 4-core machine or doing something else during evaluation are bad ideas...

⌨️ More command-line flags :: click to expand ::

• --parallel: by default half of the cores

The output should be like (below is GPT-4 greedy decoding example):

Asserting the groundtruth...
Expected outputs computed in 1200.0 seconds
Reading samples...
1140it [00:00, 1901.64it/s]
Evaluating samples...
100%|██████████████████████████████████████████| 1140/1140 [19:53<00:00, 6.75it/s]
BigCodeBench-Instruct-calibrated
Groundtruth pass rate: 1.000
pass@1: 0.568

• The "k" includes [1, 5, 10] where k values <= the sample size will be used
• A cache file named like samples_eval_results.json will be cached. Remove it to re-run the evaluation

🤔 How long it would take? :: click to expand ::

If you do greedy decoding where there is only one sample for each task, the evaluation should take just a few minutes on Intel(R) Xeon(R) Gold 6150 CPU @ 2.70GHz, composed of 2 sockets, with 18 cores per socket. However, if you have multiple samples for each task, the evaluation will take longer. Here are some tips to speed up the evaluation:

• Use --parallel $(nproc)
• Use our pre-evaluated results (see LLM-generated code)

Failure Inspection

You can inspect the failed samples by using the following command:

bigcodebench.inspect --eval-results sample-sanitized-calibrated_eval_results.json --in-place

Full Script

We provide a sample script to run the full pipeline:

bash run.sh

Result Analysis

We provide a script to replicate the analysis like Elo Rating and Task Solve Rate, which helps you understand the performance of the models further.

To run the analysis, you need to put all the `samples_eval_results.json` files in a `results` folder, which is in the same directory as the script.

```bash
cd analysis
python get_results.py

💻 LLM-generated Code

We share pre-generated code samples from LLMs we have evaluated:

• See the attachment of our v0.1.5. We include both sanitized_samples.zip and sanitized_samples_calibrated.zip for your convenience.

Known Issues

• Due to the flakes in the evaluation, the execution results may vary slightly (~0.2%) between runs. We are working on improving the evaluation stability.

• You may get errors like ImportError: /usr/local/lib/python3.10/site-packages/matplotlib/_c_internal_utils.cpython-310-x86_64-linux-gnu.so: failed to map segment from shared object when running the evaluation. This is due to the memory limit of the docker container. You can increase the memory limit of the docker container to solve this issue.

• We are aware of the issue of some users needing to use a proxy to access the internet. We are working on a subset of the tasks that do not require internet access to evaluate the code.
