rag功能不能正常使用

[zing-else]

安装稳定版（截止2025-3-19）无法使用rag功能，无法运行示例代码，会显示以下错误：
Retrying llama_index.embeddings.openai.base.get_embeddings in 1.7915908865025045 seconds as it raised NotFoundError: Error code: 404 - {'event_id': '30-inst-228-20250319170241-4fed467a', 'error_msg': 'Not Found. Please check the configuration.'}.

安装最新的稳定版metagpt==0.8.2会有依赖冲突，试过git clone方法和pip install --upgrade metagpt（pip install --upgrade git+https://github.com/geekan/MetaGPT.git）后会出现缺失包的情况：

安装'llama_index.vector_stores.milvus就会有冲突，无法解决！！！
具体是metagpt==1.0.0依赖setuptools==65.6.3，但是pymilvus 2.5.5 requires setuptools>69等等，有很多冲突无法解决！！

确实，尝试解决了一上午一直失败

由于依赖冲突，临时去掉RAG的milvus，可用main分支再试看看，相关PR

我也遇到过rag环境的问题，我按照官方手册的命令： pip install metagpt[rag] 一次性将metagpt环境和rag装好 这样安装的rag是正常的，不过embedding出现了报错，你可以试试（我的python版本是3.11）
