# 快速开始指南
|
||||
|
||||
本指南将帮助您在5分钟内运行信用卡欺诈检测系统。
|
||||
|
||||
## 前置要求
|
||||
|
||||
- Python 3.10 或更高版本
|
||||
- pip(Python包管理器)
|
||||
|
||||
## 安装步骤
|
||||
|
||||
### 1. 克隆仓库
|
||||
|
||||
```bash
|
||||
git clone <repository-url>
|
||||
cd Credit-Card-Fraud-Detection
|
||||
```
|
||||
|
||||
### 2. 创建虚拟环境(推荐)
|
||||
|
||||
**Windows:**
|
||||
```bash
|
||||
python -m venv venv
|
||||
venv\Scripts\activate
|
||||
```
|
||||
|
||||
**Linux/Mac:**
|
||||
```bash
|
||||
python3 -m venv venv
|
||||
source venv/bin/activate
|
||||
```
|
||||
|
||||
### 3. 安装依赖
|
||||
|
||||
**方式1: 使用 requirements.txt(推荐)**
|
||||
```bash
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
**方式2: 使用 setup.py**
|
||||
```bash
|
||||
pip install -e .
|
||||
```
|
||||
|
||||
**方式3: 使用 uv(需要先安装 uv)**
|
||||
```bash
|
||||
pip install uv
|
||||
uv sync
|
||||
```
|
||||
|
||||
### 4. 准备数据
|
||||
|
||||
确保 `data/creditcard.csv` 文件存在。如果不存在,请:
|
||||
|
||||
1. 从 Kaggle 下载数据集: https://www.kaggle.com/mlg-ulb/creditcardfraud
|
||||
2. 将下载的 `creditcard.csv` 文件放入 `data/` 目录
|
||||
|
||||
### 5. 训练模型
|
||||
|
||||
```bash
|
||||
python src/train.py
|
||||
```
|
||||
|
||||
训练完成后,模型文件将保存在 `models/` 目录中:
|
||||
- `random_forest_model.joblib` - 随机森林模型
|
||||
- `logistic_regression_model.joblib` - 逻辑回归模型
|
||||
- `scaler.joblib` - 特征缩放器
|
||||
|
||||
### 6. 运行应用
|
||||
|
||||
**方式1: 使用 agent_app.py(推荐)**
|
||||
```bash
|
||||
python src/agent_app.py
|
||||
```
|
||||
|
||||
这将自动启动 Web 界面并在浏览器中打开。
|
||||
|
||||
**方式2: 直接运行 Streamlit**
|
||||
```bash
|
||||
streamlit run src/streamlit_app.py
|
||||
```
|
||||
|
||||
## 使用说明
|
||||
|
||||
### Web 界面使用
|
||||
|
||||
1. **选择输入方式**
|
||||
- 上传CSV文件:批量处理交易数据
|
||||
- 手动输入:输入30个特征值
|
||||
|
||||
2. **输入特征**
|
||||
- Time: 交易时间(秒)
|
||||
- V1-V28: PCA转换后的特征
|
||||
- Amount: 交易金额
|
||||
|
||||
3. **点击"检测欺诈"按钮**
|
||||
- 系统会显示预测结果
|
||||
- 查看特征解释
|
||||
- 获取行动建议
|
||||
|
||||
### 命令行使用
|
||||
|
||||
```python
|
||||
from src.agent_app import create_agent
|
||||
|
||||
agent = create_agent()
|
||||
|
||||
transaction = [
|
||||
0, -1.3598071336738, -0.0727811733098497, 2.53634673796914, 1.37815522427443,

|
||||
149.62
|
||||
]
|
||||
|
||||
result = agent.process_transaction(transaction)
|
||||
print(f"预测类别: {result.evaluation.class_name}")
|
||||
print(f"欺诈概率: {result.evaluation.fraud_probability:.4f}")
|
||||
```
|
||||
|
||||
## 运行测试
|
||||
|
||||
```bash
|
||||
# 运行所有测试
|
||||
pytest tests/
|
||||
|
||||
# 运行特定测试文件
|
||||
pytest tests/test_data.py
|
||||
|
||||
# 查看测试覆盖率
|
||||
pytest tests/ --cov=src --cov-report=html
|
||||
```
|
||||
|
||||
## 常见问题
|
||||
|
||||
### Q1: 找不到数据文件
|
||||
|
||||
**错误信息**: `FileNotFoundError: data/creditcard.csv`
|
||||
|
||||
**解决方案**:
|
||||
1. 确保数据文件存在于 `data/` 目录
|
||||
2. 从 Kaggle 下载数据集并放入正确位置
|
||||
|
||||
### Q2: 模型文件不存在
|
||||
|
||||
**错误信息**: `RuntimeError: 模型或缩放器加载失败`
|
||||
|
||||
**解决方案**:
|
||||
```bash
|
||||
# 先训练模型
|
||||
python src/train.py
|
||||
```
|
||||
|
||||
### Q3: 依赖安装失败
|
||||
|
||||
**错误信息**: `pip install` 失败
|
||||
|
||||
**解决方案**:
|
||||
1. 确保使用 Python 3.10+
|
||||
2. 升级 pip: `pip install --upgrade pip`
|
||||
3. 使用国内镜像源: `pip install -r requirements.txt -i https://pypi.tuna.tsinghua.edu.cn/simple`
|
||||
|
||||
### Q4: Streamlit 无法启动
|
||||
|
||||
**错误信息**: `streamlit not found`
|
||||
|
||||
**解决方案**:
|
||||
```bash
|
||||
pip install streamlit
|
||||
```
|
||||
|
||||
### Q5: 端口被占用
|
||||
|
||||
**错误信息**: `Address already in use`
|
||||
|
||||
**解决方案**:
|
||||
```bash
|
||||
# 使用不同端口启动
|
||||
streamlit run src/streamlit_app.py --server.port 8502
|
||||
```
