# HumanEvalPlus


## Overview

HumanEval Plus is a rigorous extension of OpenAI's HumanEval benchmark, designed to address high false-positive rates in code generation evaluation. It augments the original test cases with tens of thousands of automatically generated inputs to expose edge-case bugs and functional errors.

## Task Description

- **Task Type**: Code Generation (Python)
- **Input**: Function signature with docstring describing expected behavior
- **Output**: Complete Python function implementation
- **Test Coverage**: Massively expanded compared to original HumanEval

## Key Features

- 164 problems from original HumanEval with enhanced test suites
- Tens of thousands of additional test cases per problem
- LLM-based and mutation-based test input generation
- Exposes edge cases and bugs missed by original HumanEval
- Much stricter and more accurate correctness evaluation

## Evaluation Notes

- Default configuration uses **0-shot** evaluation
- **Security Warning**: By default, code is executed in the local environment. We strongly recommend using sandbox execution. See the [sandbox documentation](https://evalscope.readthedocs.io/en/latest/user_guides/sandbox.html) for details.
- Supports `pass@k` metric calculation
- Default timeout is 300 seconds to accommodate extensive test suites
- Uses custom Docker image with numpy pre-installed

```text
Read the following function signature and docstring, and fully implement the function described. Your response should only contain the code for this function.
{question}
```

## Sandbox Configuration

This benchmark requires a sandbox environment for code execution.

```json
{
  "image": "python3.11-numpy",
  "tools_config": {
    "shell_executor": {},
    "python_executor": {}
  }
}
```

## Usage

### Using CLI

```bash
evalscope eval \
    --model YOUR_MODEL \
    --api-url OPENAI_API_COMPAT_URL \
    --api-key EMPTY_TOKEN \
    --datasets humaneval_plus \
    --sandbox '{"enabled": true}' \
    --limit 10  # Remove this line for formal evaluation
```

### Using Python

```python
from evalscope import run_task
from evalscope.config import TaskConfig

task_cfg = TaskConfig(
    model='YOUR_MODEL',
    api_url='OPENAI_API_COMPAT_URL',
    api_key='EMPTY_TOKEN',
    datasets=['humaneval_plus'],
    sandbox={'enabled': True},
    limit=10,  # Remove this line for formal evaluation
)

run_task(task_cfg=task_cfg)
```
