这个函数使用LlamaIndex的SimpleDirectoryReader来加载数据,创建ServiceContext以配置RAG管道,然后使用VectorStoreIndex来构建数据的索引。这个函数使用Streamlit的@st.cache_resource装饰器来缓存数据加载以提高性能。 @st.cache_resource(show_spinner=False) def load_data(): with st.spinner(text="Loading and indexing t...
定义向量存储,在节点上创建RAG indexing pipeline。 from llama_index.core import VectorStoreIndex vector_index = VectorStoreIndex(nodes) query_engine = vector_index.as_query_engine(similarity_top_k=2) 与上节不同,这里我们尝试用元数据过滤器查询RAG pipeline。 from llama_index.core.vector_stores import...

Both LlamaIndex and LangChain have active communities, with Langchain moving towards more open-source contributions. Collaborative features LangChain's has built-in support for team collaboration through LangSmith, and LlamaIndex does not. However, it's still not easy to pull in PMs ...
Vector Indexing:LlamaIndex uses vector indexing, a technique to represent text data as numerical vectors. This makes it easier for the LLM to understand and compare different pieces of information. LangChain Integration:This step highlights how LangChain can be integrated ...
