动手实操微软开源的GraphRAG

微软在今年4月份的时候提出了GraphRAG的概念，然后在上周开源了GraphRAG,Github链接见https://github.com/microsoft/graphrag,截止当前，已有6900+Star。

安装教程

官方推荐使用Python3.10-3.12版本，我使用Python3.10版本安装时，在初始化项目过程中会报错，切换到Python3.11版本后运行正常，推测是Python3.10与微软的一些最新的SDK不兼容。所以建议使用Python3.11的环境，安装GraphRAG比较简单，直接下面一行代码即可安装成功。

pip install graphrag

使用教程

在这个教程中，我们使用马伯庸的《太白金星有点烦》这个短篇小说为例，测试下使用微软开源的GraphRAG的处理效果。

注意，GraphRAG是使用LLM来提取文本片段中的实体关系，因此耗费Token数较多，如果是个人调研使用，不建议使用GPT4级别的模型（费用太高，不差钱的大佬请忽略此条建议）。综合成本和效果，我这里使用的是DeepSeek-Chat模型。

初始化项目

我这边先创建了一个临时测试目录myTest，然后按照官方教程，在myTest目录下创建了input目录，并把《太白金星有点烦》这本书的txt版本重命名为book.txt后放到input目录下。然后调用python -m graphrag.index --init 进行初始化工作，生成一些配置文件。

mkdir ./myTest/input
curl https://www.xxx.com/太白金星有点烦.txt > ./myTest/input/book.txt  // 这里是示例代码，大家在测试时根据实际情况放入自己要测试的txt文本即可。
cd ./myTest
python -m graphrag.index --init

执行完成后，会在当前目录（即MyTest）目录下生成几个新的文件夹：output-后续执行生成的中间结果会保存到这个目录中；prompts-处理过程中用到的一些Prompt内容；.env-大模型API配置文件，里面默认就一个GRAPHRAG_API_KEY 用于配置大模型的apiKey；settings.yaml-该文件是整体的配置信息，如果我们使用的非OPENAI的官方模型和官方API，我们需要修改此配置文件来让GraphRAG按照我们指定的配置文件执行。

配置相关文件

先在.env文件中配置大模型API的Key，这个配置是全局生效的。我们在.env文件中配置完成后，不需要在settings.yaml文件中重复配置。settings.yaml中使用的默认模型为gpt-4-turbo-preview ，如果不需要修改模型以及调用的API地址，那现在就已经配置完成了，后续的配置内容可以执行忽略并直接到执行阶段。

我这里使用的是agicto 提供的APIkey(主要是新用户注册可以免费获取到10块钱的调用额度，白嫖还是挺爽的)。我在这里主要就修改了API地址和调用模型的名称，修改完成后的settings文件完整内容如下：

执行并构建图索引

此流程是GraphRAG的核心流程，即构建基于图的知识库用于后续的问答环节，通过以下代码即可触发执行。

python -m graphrag.index

基于微软在论文中提到的实现思路，执行过程GraphRAG主要实现了如下功能：

1. Source Documents → Text Chunks：将源文档分割成文本块。
2. Text Chunks → Element Instances：从每个文本块中提取图节点和边的实例。
3. Element Instances → Element Summaries：为每个图元素生成摘要。
4. Element Summaries → Graph Communities：使用社区检测算法将图划分为社区。
5. Graph Communities → Community Summaries：为每个社区生成摘要。
6. Community Summaries → Community Answers → Global Answer：使用社区摘要生成局部答案，然后汇总这些局部答案以生成全局答案。

整体执行耗时与具体的文本大小有关。我这个例子整体耗时大概20分钟，耗费人民币大约4块钱。执行过程中的输出如下：

基于构建的知识库进行提问

GraphRAG支持两种提问方式，“global search"和"local search”。"global search"指的是那些需要理解整个文本语料库的问题，例如“数据集的主要主题是什么？”这类问题需要一种全局性的理解和摘要，而不是仅从文本的局部区域中检索信息。相反，"local search"在论文中通常指的是文本的局部区域或文本块，这些局部区域是RAG方法检索的单元。

让GraphRAG帮我介绍下这篇文章都讲述了什么内容，执行代码如下：

python -m graphrag.query --root ../myTest --method global "这篇文章主要讲述 了什么内容?"

输出内容为：

同样的问题，我们使用"local search"的方式再问一下，执行代码

python -m graphrag.query --root ../myTest --method local "这篇文章主要讲述了什么内容?"

输出内容为：

李长庚在天庭中担任多项关键职责，包括启明司的主持和护法锦囊设计等。他的行为和决策直接影响天庭的稳定和取经任务的进展。李长庚的复杂角色和多重职责使得他在天庭中的影响力极大，同时也带来了较高的潜在风险。[Data: Entities (5), Relationships (49, 82, 39, 58, 83, 138, 155, 74, 46)]### 李长庚与观音的复杂关系
李长庚与观音之间的关系复杂且多层次，涉及合作、争论和策略性互动。他们共同经历了多次困难，彼此之间有着默契的默契。李长庚通过无形的影响来应对观音的威胁，而观音对李长庚的安排感到不满。这种复杂的关系对取经任务的进展有着直接的影响。[Data: Relationships (49)]### 李长庚与孙悟空的密切关系
李长庚与孙悟空之间的关系复杂且密切，涉及指导、关心和策略性互动。孙悟空对李长庚的修行状态和关心的事情表示理解，而李长庚则提醒孙悟空注意因果。两人之间的直接交流和合作对取经任务的进展至关重要。[Data: Relationships (82)]### 李长庚与玄奘的互动
李长庚与玄奘之间存在着一系列复杂的关系和互动。李长庚正在策划一个与玄奘旅程相关的事件，这表明他对玄奘的经历和成就有着浓厚的兴趣。两人之间的争议和合作对取经任务的进展有着重要影响。[Data: Relationships (39)]### 李长庚与取经队伍的关系
李长庚与取经队伍的关系复杂且充满关怀。尽管他本人并未直接参与取经队伍的活动，但他的讨论发生在取经队伍活动的背景下。李长庚为取经队伍护法渡劫，显示出他对该组织的忠诚和支持。[Data: Relationships (58)]这篇文章通过详细描述李长庚在天庭中的角色及其与观音、孙悟空、玄奘和取经队伍的关系，展现了他在天庭和取经任务中的核心地位和重要作用。

对比之下可以看出，"local search"的查询方式确实会透出更多细节信息。

以上就是这篇文章的主要内容，第二篇文章我会找一个典型的文章，对比下GraphRAG和常规RAG在实际场景中的使用效果，第三篇文章会介绍下GraphRAG的主要实现原理（工作日通常会加班，下班较晚，回家后需要陪陪家人，因此更新可能会慢点，预计下周末出第二篇）。如果想看更多的理论细节，推荐阅读https://arxiv.org/pdf/2404.16130。

感谢大家能看到最后，欢迎大家有时间也来我的个人博客看看，更新的内容会更多些。不来也没关系，我觉得有价值的内容也会继续在CSDN上更新。
