Tools (optional)— Depending on the tools you want the LLM to interact with such as OpenWeatherMap or SerpAPI, you may need to register with them to obtain an API key and check their pricing. In this tutorial, we only use tools requiring no API key.工具(可选)-根据您希望LLM与之交互的...

Likewise, if a given generative AI task requires access to external software workflows—for example, if you wanted your virtual agent tointegrate with Slack—then you will need a way to integrate the LLM with theAPIfor that software. While these integrations can generally be achieved with fully ...
We’ll start with a simple chatbot that can interact with just one document and finish up with ...
RAG isn’t as simple as making a quick query and continuing to interact with the LLM. There are a few intermediate steps that have to happen. Also, data has to be stored in an understood format so that retrieval is simple and consistent. ...
LangChain uses SQLAlchemy to interact with databases, and SQLAlchemy, in turn, uses DBAPI (Database API), such as pyodbc, to connect to various databases including Microsoft SQL Server. To fix this issue, you need to ensure that the decimal values you're trying to insert or update in th...
sys: This module provides access to some variables used or maintained by the interpreter and functions that interact with the interpreter. openai: The OpenAI Python library provides convenient access to the OpenAI API from applications written in Python. It includes a pre-defined set of classes for...
these inputs can come from memory. A chain will interact with its memory system twice in a given run. AFTER receiving the initial user inputs but BEFORE executing the core logic, a chain will READ from its \ memory system and augment the user inputs. ...
首先要声明一下,本文要开发的实际上是tools,并不是Agent。根据LangChain官方文档:Tools are interfaces that an agent, chain, or LLM can use to interact with the world.中文意思为“工具是代理、链或LLM可以用来与世界交互的接口”,最终Agent来使用工具,实现某些功能或操作。如有疑问➕V:DuOTOR2A...
我们将要定义的这个提示模板可用于任何其他 AI 应用程序。 加载环境变量 在此步骤中,我们将从 .env 文件加载环境变量。这是我们将存储OpenAI API密钥和其他配置设置的地方。 导入库 在此步骤中,我们将从 LangChain 模块导入 PromptTemplate 类。这将用于定义用于生成响应的模板。 我们将从 LangChain 的 chains ...
