《选修-Building and Evaluating Advanced RAG Applications》课程给的requirements.txt存在Dependency Hell

[LinsCodes]

Dependency Hell

我用的conda 安装的虚拟环境是python 3.11.11（conda create --name xxxx python=3.11 -y） ，安装依赖时（pip install -r requirements.txt）发现
出现如下报错：

ERROR: Cannot install -r requirements.txt (line 101), -r requirements.txt (line 118),-r requirements.txt (line 111), -r reguirements.txt (line 3), -r requirements.txt (line 4),-r reguirements.txt (line 47), -r requirements.txt (line 71),-r requirements.txt (line 94) and typing extensions==4.5.0 because these package versions
have conflicting dependencies.
The conflict is caused by:

        The user requested typing extensions==4.5.0
        aiostream 0.5.2 depends on typing-extensions
        alembic 1.13.1 depends on typing-extensions>=4
        huggingface-hub 0.21.4 depends on typing-extensions>=3.7.4.3
        llama-index 0.9.8 depends on typing-extensions>=4.5.0
        openai 1.3.5 depends on typing-extensions<5 and >=4.5
        pinecone-client 3.1.0 depends on typing-extensions>=3.7.4
        pydantic 1.10.14 depends on typing-extensions>=4.2.0
        pydantic-core 2.16.3 depends on typing-extensions!=4.7.0 and >=4.6.0

        To fix this you could try to:
        1. loosen the range of package versions you've specified
        2. remove package versions to allow pip to attempt to solve the dependency conflict
        3.

总结来看：

    requirements.txt显式指定了` typing_extensions==4.5.0`。
    但多个依赖包（如llama-index, pydantic-core, openai等）要求更高版本：
    llama-index: >=4.5.0
    pydantic-core: >=4.6.0 且 !=4.7.0
    openai: >=4.5 且 <5
