GraphRAG+ollama+LM Studio+chainlit

这里我们进一步尝试将embedding模型也换为本地的，同时熟悉一下流程和学一些新的东西

1.环境还是用之前的，这里我们先下载LLM  

然后你会在下载nomic模型的时候崩溃，因为无法搜索，无法下载

解决办法如下
lm studio 0.2.24国内下载模型_lm studio 国内源-CSDN博客

按照上面的教程依旧无法下载模型，但是可以搜索了，没什么用

直接hugging face下载，然后导入llm  models文件夹

C:\Users\Administrator\.cache\lm-studio\models

注意有格式要求

C:\Users\Administrator\.cache\lm-studio\models\Publisher\Repository
将模型放在这个文件夹里才能被识别，然后加在模型

然后修改配置

settings.yaml

##我这里用到是我的另一个电脑运行LLM Studio  ，所以IP是127
