#### 3.2.5 数据增强策略
|
| 451 |
-
|
| 452 |
-
1. **问题变体生成**: 同一知识点生成 3-5 种不同问法
|
| 453 |
-
2. **上下文扩展**: 添加相关代码元素作为背景信息
|
| 454 |
-
3. **难度分层**:
|
| 455 |
-
- 简单: 单一元素解释
|
| 456 |
-
- 中等: 多元素关系分析
|
| 457 |
-
- 困难: 架构级设计方案
|
| 458 |
-
|
| 459 |
-
#### 3.2.6 数据集划分
|
| 460 |
-
|
| 461 |
-
- **训练集 (80%)**: train.jsonl - 用于模型学习
|
| 462 |
-
- **验证集 (10%)**: val.jsonl - 用于超参数调优
|
| 463 |
-
- **测试集 (10%)**: test.jsonl - 用于最终评估
|
| 464 |
-
|
| 465 |
-
**metadata.json 示例**:

model = get_peft_model(model, lora_config)
|
| 581 |
-
|
| 582 |

|
| 585 |
-
args=training_args,

### 3.4 模块4: LoRA 权重合并器 (LoRA Merger)
|
| 618 |
-
|
| 619 |
-
#### 3.4.1 合并原理
|
| 620 |
-
|
| 621 |
-
LoRA 训练产生的是**增量参数** (adapter),需要合并回基础模型才能独立使用。
|
| 622 |
-
|
| 623 |
-
**合并公式**:
|
| 624 |
-
```
|
| 625 |
-
W_merged = W_base + (B × A) × alpha / r
|
| 626 |
-
```
|
| 627 |
-
其中:
|
| 628 |
-
- W_base: 基础模型权重
|
| 629 |
-
- B, A: LoRA 低秩矩阵
|
| 630 |
-
- alpha, r: LoRA 超参数
|
| 631 |
-
|
| 632 |
-
#### 3.4.2 合并流程
|
| 633 |
-
|
| 634 |
-
```python
|
| 635 |
-
# 1. 加载基础模型
|
| 636 |
-
base_model = AutoModelForCausalLM.from_pretrained(
|
| 637 |
-
base_model_path,
|
| 638 |
-
torch_dtype=torch.bfloat16
|
| 639 |
-
)
|
| 640 |
-
|
| 641 |
-
# 2. 加载 LoRA adapter
|
| 642 |
-
model = PeftModel.from_pretrained(
|
| 643 |
-
base_model,
|
| 644 |
-
lora_adapter_path
|
| 645 |
-
)
|
| 646 |
-
|
| 647 |
-
# 3. 合并权重
|
| 648 |
-
merged_model = model.merge_and_unload()
|
| 649 |
-
|
| 650 |
-
# 4. 保存完整模型
|
| 651 |
-
merged_model.save_pretrained(
|
| 652 |
-
"output/merged_model",
|
| 653 |
-
safe_serialization=True # 使用 safetensors 格式
|
| 654 |

## 4. 数据质量保证
|
| 839 |
-
|
| 840 |
-
### 4.1 数据多样性策略
|
| 841 |
-
|
| 842 |
-
1. **问题多样性**:
|
| 843 |
-
- 每个知识点生成 3-5 种不同问法
|
| 844 |
-
- 覆盖不同难度层级
|
| 845 |
-
- 包含不同问答风格
|
| 846 |
-
|
| 847 |
-
2. **代码覆盖率**:
|
| 848 |
-
- 选择复杂度 > 5 的函数
|
| 849 |
-
- 包含不同类型的元素 (class, function, method)
|
| 850 |
-
- 覆盖不同业务场景
|
| 851 |
-
|
| 852 |
-
3. **上下文丰富性**:
|
| 853 |
-
- 提供完整代码片段
|
| 854 |
-
- 包含文件路径和行号
|
| 855 |
-
- 附带相关元素引用
|
| 856 |
-
|
| 857 |
-
### 4.2 数据验证机制
|
| 858 |
-
|
| 859 |
-
1. **格式验证**:
|
| 860 |
-
- JSONL 格式正确性
|
| 861 |
-
- conversations 字段完整性
|
| 862 |
-
- metadata 字段一致性
|
| 863 |
-
|
| 864 |
-
2. **内容验证**:
|
| 865 |
-
- 答案是否包含代码引用
|
| 866 |
-
- 答案是否提及项目名称
|
| 867 |
-
- 答案长度是否合理 (50-1000 字符)
|
| 868 |
-
|
| 869 |
-
3. **去重验证**:
|
| 870 |
-
- 基于问题文本的去重
|
| 871 |
-
- 基于代码元素的去重
|
| 872 |
-
|
| 873 |
-
### 4.3 推理轨迹 (Reasoning Trace)
|
| 874 |
-
|
| 875 |
-
在设计方案类任务中,提供清晰的推理过程:
|
| 876 |
-
|
| 877 |
-
**示例**:
|
| 878 |
-
```
|
| 879 |
-
问题: 如何在 Laddr 中添加新的工具 (Tool)?
|
| 880 |
-
|
| 881 |
-
答案:
|
| 882 |
-
在 Laddr 中添加新工具需要以下步骤:
|
| 883 |
-
|
| 884 |
-
**推理过程**:
|
| 885 |
-
1. 分析现有工具实现模式
|
| 886 |
-
- 参考 `core/tooling.py` 中的 `BaseTool` 类
|
| 887 |
-
- 查看 `core/system_tools.py` 中的示例工具
|
| 888 |
-
|
| 889 |
-
2. 识别依赖模块
|
| 890 |
-
- 工具注册: `core/tooling.py` 的 `register_tool()`
|
| 891 |
-
- 工具调用: `core/agent_runtime.py` 的 `execute_tool()`
|
| 892 |
-
|
| 893 |
-
3. 实现步骤
|
| 894 |
-
(1) 创建新工具类,继承 `BaseTool`
|
| 895 |
-
(2) 实现 `execute()` 方法
|
| 896 |
-
(3) 添加工具元数据 (name, description, parameters)
|
| 897 |
-
(4) 在 agent 配置中注册工具
|
| 898 |
-
|
| 899 |
-
**参考代码**:
|
| 900 |
-
见 `core/system_tools.py` 第 45-80 行的 `FileReadTool` 实现。
|
| 901 |
-
```
|
| 902 |
-
|
| 903 |
-

|
| 904 |
-
|
| 905 |
-
## 5. 可扩展性设计
|
| 906 |
-
|
| 907 |
-
### 5.1 支持多语言 (可选功能)
|
| 908 |
-
|
| 909 |
-
**当前支持**: Python, Markdown
|
| 910 |
-
|
| 911 |
-
**扩展方案**:
|
| 912 |
-
1. 添加新的语言解析器 (如 JavaScript AST 解析)
|
| 913 |
-
2. 在 `config/default_config.yaml` 中配置支持的语言
|
| 914 |
-
3. 实现对应的代码元素提取逻辑
|
| 915 |
-
|
| 916 |
-
**配置示例**:
|
| 917 |
-
```yaml
|
| 918 |
-
repository:
|
| 919 |
-
languages:
|
| 920 |
-
- python
|
| 921 |
-
- javascript # 扩展
|
| 922 |
-
- java # 扩展
|
| 923 |
-
```
|
| 924 |
-
|
| 925 |
-
### 5.2 支持新的任务类型
|
| 926 |
-
|
| 927 |
-
**扩展接口**:
|
| 928 |
-
```python
|
| 929 |
-
class DataGenerator:
|
| 930 |
-
def add_custom_task_generator(self, task_name: str, generator_func):
|
| 931 |
-
"""添加自定义任务生成器"""
|
| 932 |
-
self.task_generators[task_name] = generator_func
|
| 933 |
-
```
|
| 934 |
-
|
| 935 |
-
**示例**:
|
| 936 |
-
```python
|
| 937 |
-
def generate_bug_fix_samples(code_elements):
|
| 938 |
-
# 生成 bug 修复类训练样本
|
| 939 |
-
pass
|
| 940 |
-
|
| 941 |
-
generator = DataGenerator()
|
| 942 |
-
generator.add_custom_task_generator("bug_fix", generate_bug_fix_samples)
|
| 943 |
-
```
|
| 944 |
-
|
| 945 |
-
### 5.3 支持更大规模的代码仓库
|
| 946 |
-
|
| 947 |
-
**优化方案**:
|
| 948 |
-
1. **分批处理**: 将大型仓库分批解析
|
| 949 |
-
2. **增量更新**: 只分析修改的文件
|
| 950 |
-
3. **并行处理**: 多进程并行分析不同模块
|
| 951 |
-
|
| 952 |

## Limitations
|
| 194 |
+
|
| 195 |
+
- **Project-Specific**: Optimized for Laddr project; may not perform as well on other codebases
|
| 196 |
+
- **Knowledge Cutoff**: Based on the Laddr repository as of training time (2025-01)
|
| 197 |
+
- **Language Focus**: Primarily trained on Python code and English/Chinese documentation
|
| 198 |
+
- **Limited General Coding**: While it maintains general knowledge, it's optimized for Laddr-specific queries
|
| 199 |
+
|
| 200 |
+
## Training Methodology
|
| 201 |
+
|
| 202 |
+
### Innovation: LLM-Free Training Data Generation
|
| 203 |
+
|
| 204 |
+
Unlike traditional approaches that use LLMs to generate synthetic training data, this project employs a novel methodology:
|
| 205 |
+
|
| 206 |
+
1. **AST-Based Code Parsing**: Python Abstract Syntax Tree analysis extracts accurate code structure
|
| 207 |
+
2. **Real Documentation**: Utilizes actual docstrings, comments, and code signatures
|
| 208 |
+
3. **Call Graph Analysis**: Builds function dependency relationships
|
| 209 |
+
4. **Pattern Extraction**: Identifies code patterns (implementation, usage, interaction)
|
| 210 |
+
5. **Template-Based QA**: Generates question-answer pairs using templates with real code context
|
| 211 |
+
|
| 212 |
+
**Benefits**:
|
| 213 |
+
- ✅ Avoids circular dependency (using LLM data to train LLM)
|
| 214 |
+
- ✅ Eliminates hallucination in training data
|
| 215 |
+
- ✅ Ensures factual accuracy
|
| 216 |
+
- ✅ Provides complete reasoning traces
|
| 217 |
+
|
| 218 |
+

## Ethical Considerations
|
| 278 |
|
| 279 |
+
- **Code Attribution**: All training data comes from the open-source Laddr repository
|
| 280 |
+
- **License Compliance**: Respects Apache 2.0 license of both base model and Laddr project
|
| 281 |
+
- **No Private Data**: Only uses publicly available code
|
| 282 |
+
- **Reproducibility**: Complete methodology documented for transparency

| 198 |
+
def _build_call_graph():
|
| 199 |
+
for element in code_elements:
|
| 200 |
+
if element.type in ['function', 'method']:
|
| 201 |
+
for called in element.called_functions:
|
| 202 |
+
function_calls_graph[element.name].add(called)
|
| 203 |
+
```
|
| 204 |
+
|
| 205 |
+
**代码模式提取**
|
| 206 |
+
```python
|
| 207 |
+
def _extract_code_patterns():

|
| 209 |
+
for class_element in classes:
|
| 210 |
+
if class_element.docstring:
|
| 211 |
+
create_pattern("class_implementation", ...)
|
| 212 |
+
|
| 213 |
+

### 3.2 模块2: 训练数据生成器 (Data Generator)
|
| 290 |
+
|
| 291 |
+
#### 3.2.1 设计理念
|
| 292 |
+
- **基于真实代码**: 所有问答对直接来源于实际代码和文档,不依赖LLM生成
|
| 293 |
+
- **模板化方法**: 使用精心设计的模板确保数据质量和一致性
|
| 294 |
+
- **多样性保证**: 通过不同问题模板和代码元素组合实现多样性
|
| 295 |
+
- **可验证性**: 每个答案都可以追溯到源代码
|
| 296 |
+
|
| 297 |
+
#### 3.2.2 训练数据集结构
|
| 298 |
+
|
| 299 |
+
**TrainingSample 数据结构**
|
| 300 |
+
```python
|
| 301 |
+
@dataclass
|
| 302 |
+
class TrainingSample:
|
| 303 |
+
conversations: List[Dict[str, str]] # [{"role": "user", "content": "..."}, {"role": "assistant", "content": "..."}]
|
| 304 |
+
metadata: Dict[str, Any] # {"task_type": "...", "element_name": "...", "filepath": "..."}
|
| 305 |
+
```
|
| 306 |
+
|
| 307 |
+
**JSONL 格式示例**
|
| 308 |
+
```jsonl
|
| 309 |
+
{"conversations": [{"role": "user", "content": "请解释 Laddr 中 `AgentRuntime` 的作用。"}, {"role": "assistant", "content": "`AgentRuntime` 是 Laddr 项目中的一个 类,位于 `lib/laddr/src/laddr/core/agent_runtime.py`。\n\n**功能描述**:\nAgent runtime manager that coordinates tool execution, message handling, and state management.\n\n**函数签名**:\n```python\nclass AgentRuntime:\n def __init__(self, config: AgentConfig):\n```"}], "metadata": {"task_type": "code_explanation", "element_name": "AgentRuntime", "filepath": "lib/laddr/src/laddr/core/agent_runtime.py"}}
|
| 310 |
+
```
|
| 311 |
+
|
| 312 |
+

### 3.4 模块4: LoRA 权重合并器 (LoRA Merger)
|
| 618 |
+
|
| 619 |
+
#### 3.4.1 合并原理
|
| 620 |
+
|
| 621 |
+
LoRA 训练产生的是**增量参数** (adapter),需要合并回基础模型才能独立使用。
|
| 622 |
+
|
| 623 |
+
**合并公式**:
|
| 624 |
+
```
|
| 625 |
+
W_merged = W_base + (B × A) × alpha / r
|
| 626 |
+
```
|
| 627 |
+
其中:
|
| 628 |
+
- W_base: 基础模型权重
|
| 629 |
+
- B, A: LoRA 低秩矩阵
|
| 630 |
+
- alpha, r: LoRA 超参数
|
| 631 |
+
|
| 632 |
+
#### 3.4.2 合并流程
|
| 633 |
+
|
| 634 |
+
```python
|
| 635 |
+
# 1. 加载基础模型
|
| 636 |
+
base_model = AutoModelForCausalLM.from_pretrained(
|
| 637 |
+
base_model_path,
|
| 638 |
+
torch_dtype=torch.bfloat16
|
| 639 |
+
)
|
| 640 |
+
|
| 641 |
+
# 2. 加载 LoRA adapter
|
| 642 |
+
model = PeftModel.from_pretrained(
|
| 643 |
+
base_model,
|
| 644 |
+
lora_adapter_path
|
| 645 |
+
)
|
| 646 |
+
|
| 647 |
+
# 3. 合并权重
|
| 648 |
+
merged_model = model.merge_and_unload()
|
| 649 |
+
|
| 650 |
+
# 4. 保存完整模型
|
| 651 |
+
merged_model.save_pretrained(
|
| 652 |
+
"output/merged_model",
|
| 653 |
+
safe_serialization=True # 使用 safetensors 格式
|
| 654 |
+
)
|
| 655 |

## 4. 数据质量保证
|
| 839 |
+
|
| 840 |
+
### 4.1 数据多样性策略
|
| 841 |
+
|
| 842 |
+
1. **问题多样性**:
|
| 843 |
+
- 每个知识点生成 3-5 种不同问法
|
| 844 |
+
- 覆盖不同难度层级
|
| 845 |
+
- 包含不同问答风格
|
| 846 |
+
|
| 847 |
+
2. **代码覆盖率**:
|
| 848 |
+
- 选择复杂度 > 5 的函数
|
| 849 |
+
- 包含不同类型的元素 (class, function, method)
|
| 850 |
+
- 覆盖不同业务场景
|
| 851 |
+
|
| 852 |
+
3. **上下文丰富性**:
|
| 853 |
+
- 提供完整代码片段
|
| 854 |
+
- 包含文件路径和行号
|
| 855 |
+
- 附带相关元素引用
|
| 856 |
+
|
| 857 |
+
### 4.2 数据验证机制
|
| 858 |
+
|
| 859 |
+
1. **格式验证**:
|
| 860 |
+
- JSONL 格式正确性
|
| 861 |
+
- conversations 字段完整性
|
| 862 |
+
- metadata 字段一致性
|
| 863 |
+
|
| 864 |
+
2. **内容验证**:
|
| 865 |
+
- 答案是否包含代码引用
|
| 866 |
+
- 答案是否提及项目名称
|
| 867 |
+
- 答案长度是否合理 (50-1000 字符)
|
| 868 |
+
|
| 869 |
+
3. **去重验证**:
|
| 870 |
+
- 基于问题文本的去重
|
| 871 |
+
- 基于代码元素的去重
|
| 872 |
+
|
| 873 |
+
### 4.3 推理轨迹 (Reasoning Trace)
|
| 874 |
+
|
| 875 |
+
在设计方案类任务中,提供清晰的推理过程:
|
| 876 |
+
|
| 877 |
+
**示例**:
|
| 878 |
+
```
|
| 879 |
+
问题: 如何在 Laddr 中添加新的工具 (Tool)?
|
| 880 |
+
|
| 881 |
+
答案:
|
| 882 |
+
在 Laddr 中添加新工具需要以下步骤:
|
| 883 |
+
|
| 884 |
+
**推理过程**:
|
| 885 |
+
1. 分析现有工具实现模式
|
| 886 |
+
- 参考 `core/tooling.py` 中的 `BaseTool` 类
|
| 887 |
+
- 查看 `core/system_tools.py` 中的示例工具
|
| 888 |
+
|
| 889 |
+
2. 识别依赖模块
|
| 890 |
+
- 工具注册: `core/tooling.py` 的 `register_tool()`
|
| 891 |
+
- 工具调用: `core/agent_runtime.py` 的 `execute_tool()`
|
| 892 |
+
|
| 893 |
+
3. 实现步骤
|
| 894 |
+
(1) 创建新工具类,继承 `BaseTool`
|
| 895 |
+
(2) 实现 `execute()` 方法
|
| 896 |
+
(3) 添加工具元数据 (name, description, parameters)
|
| 897 |
+
(4) 在 agent 配置中注册工具
|
| 898 |
+
|
| 899 |
+
**参考代码**:
|
| 900 |
+
见 `core/system_tools.py` 第 45-80 行的 `FileReadTool` 实现。
|
| 901 |
+
```
|
| 902 |
+
|
| 903 |
+

|
| 904 |
+
|
| 905 |
+
## 5. 可扩展性设计
|
| 906 |
+
|
| 907 |
+
### 5.1 支持多语言 (可选功能)
|
| 908 |
+
|
| 909 |
+
**当前支持**: Python, Markdown
|
| 910 |
+
|
| 911 |
+
**扩展方案**:
|
| 912 |
+
1. 添加新的语言解析器 (如 JavaScript AST 解析)
|
| 913 |
+
2. 在 `config/default_config.yaml` 中配置支持的语言
|
| 914 |
+
3. 实现对应的代码元素提取逻辑
|
| 915 |
+
|
| 916 |
+
**配置示例**:
|
| 917 |
+
```yaml
|
| 918 |
+
repository:
|
| 919 |
+
languages:
|
| 920 |
+
- python
|
| 921 |
+
- javascript # 扩展
|
| 922 |
+
- java # 扩展
|
| 923 |
+
```
|
| 924 |
+
|
| 925 |
+
### 5.2 支持新的任务类型
|
| 926 |
+
|
| 927 |
+
**扩展接口**:
|
| 928 |
+
```python
|
| 929 |
+
class DataGenerator:
|
| 930 |
+
def add_custom_task_generator(self, task_name: str, generator_func):
|
| 931 |
+
"""添加自定义任务生成器"""
|
| 932 |
+
self.task_generators[task_name] = generator_func
|
| 933 |
+
```
|
| 934 |
+
|
| 935 |
+
**示例**:
|
| 936 |
+
```python
|
| 937 |
+
def generate_bug_fix_samples(code_elements):
|
| 938 |
+
# 生成 bug 修复类训练样本
|
| 939 |
+
pass
|
| 940 |
+
|
| 941 |
+
generator = DataGenerator()
|
| 942 |
+
generator.add_custom_task_generator("bug_fix", generate_bug_fix_samples)
|
| 943 |
+
```
|
| 944 |
+
|
| 945 |
+
### 5.3 支持更大规模的代码仓库
|
| 946 |
+
|
| 947 |
+
**优化方案**:
|
| 948 |
+
1. **分批处理**: 将大型仓库分批解析
|
| 949 |
+
2. **增量更新**: 只分析修改的文件
|
| 950 |
+
3. **并行处理**: 多进程并行分析不同模块
|
| 951 |
+
