Nov 7, 2024 · The create_csv_agent function in LangChain works by chaining several layers of agents under the hood to interpret and execute natural language queries on a CSV file. LangChain is a software framework that helps facilitate the integration of large language models (LLMs) into applications. How to: use prompting to improve results How to: do query validation How to: deal with large databases How to: deal with CSV files Q&A over graph databases You can use an LLM to do question answering over graph databases. Build a Question Answering application over a Graph Database In this guide we’ll go over the basic ways to create a Q&A chain over a graph database. LangChain is a framework for developing applications powered by large language models (LLMs). It covers four different types of chains: stuff, map_reduce, refine, map_rerank. 开发：使用 LangChain 的开源 组件 和 第三方集成 构建您的应用程序。 使用 LangGraph 来构建支持一流流式传输和人工干预的有状态智能体。 生产化：使用 LangSmith 来检查、监控和评估您的应用程序，以便您可以持续优化并自信地部署。 部署：使用 LangGraph Platform 将您的 LangGraph 应用程序转化为可用于生产的 API 和助手。 LangChain 为大型语言模型及相关技术（如嵌入模型和向量存储）实现了标准接口，并集成了数百家提供商。 有关更多信息，请参阅 集成 页面。 Q&A with RAG Overview One of the most powerful applications enabled by LLMs is sophisticated question-answering (Q&A) chatbots. The CSV agent then uses tools to find solutions to your questions and generates an appropriate response with the help of a LLM. LLMs can reason Jan 9, 2024 · A short tutorial on how to get an LLM to answer questins from your own data by hosting a local open source LLM through Ollama, LangChain and a Vector DB in just a few lines of code. For this example we do similarity search over a vector database, but these Jun 29, 2024 · We’ll use LangChain to create our RAG application, leveraging the ChatGroq model and LangChain's tools for interacting with CSV files. It helps you chain together interoperable components and third-party integrations to simplify AI application development — all while future-proofing decisions as the underlying technology evolves. The application employs Streamlit to create the graphical user interface (GUI) and utilizes Langchain to interact with Jul 21, 2023 · We used Streamlit as the frontend to accept user input (CSV file, questions about the data, and OpenAI API key) and LangChain for backend processing of the data via the pandas DataFrame Agent. The application reads the CSV file and processes the data. LangChain 是一个用于开发由语言模型驱动的应用程序的框架。 我们相信，最强大和不同的应用程序不仅将通过 API 调用语言模型，还将： 数据感知：将语言模型与其他数据源连接在一起。 主动性：允许语言模型与其环境进行交互。 因此，LangChain 框架的设计目标是为了实现这些类型的应用程序。 组件：LangChain 为处理语言模型所需的组件提供模块化的抽象。 LangChain 还为所有这些抽象提供了实现的集合。 这些组件旨在易于使用，无论您是否使用 LangChain 框架的其余部分。 用例特定链：链可以被看作是以特定方式组装这些组件，以便最好地完成特定用例。 这旨在成为一个更高级别的接口，使人们可以轻松地开始特定的用例。 这些链也旨在可定制化。 LangChain is a framework for building LLM-powered applications. These applications use a technique known as Retrieval Augmented Generation, or RAG. For a more in depth explanation of what these chain types are, see here. These systems will allow us to ask a question about the data in a graph database and get back a natural language answer. As a language model integration framework, LangChain's use-cases largely overlap with those of language models in general, including document analysis and summarization, chatbots, and code analysis. Prepare Data # First we prepare the data. ⚠️ Security note ⚠️ Building Q&A systems of graph databases requires executing model-generated graph queries. Apr 13, 2023 · The result after launch the last command Et voilà!
