# 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

## 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)
```
