langchain glm
v0.0.2
本项目通过langchain的基础组件,实现了完整的支持智能体和相关任务架构。底层采用智谱AI的最新的 GLM-4 All Tools
, 通过智谱AI的API接口,
能够自主理解用户的意图,规划复杂的指令,并能够调用一个或多个工具(例如网络浏览器、Python解释器和文本到图像模型)以完成复杂的任务。
图|GLM-4 All Tools 和定制 GLMs(智能体)的整体流程。
包路径 | 说明 |
---|---|
agent_toolkits | 平台工具AdapterAllTool适配器, 是一个用于为各种工具提供统一接口的平台适配器工具,目的是在不同平台上实现无缝集成和执行。该工具通过适配特定的平台参数,确保兼容性和一致的输出。 |
agents | 定义AgentExecutor的输入、输出、智能体会话、工具参数、工具执行策略的封装 |
callbacks | 抽象AgentExecutor过程中的一些交互事件,通过事件展示信息 |
chat_models | zhipuai sdk的封装层,提供langchain的BaseChatModel集成,格式化输入输出为消息体 |
embeddings | zhipuai sdk的封装层,提供langchain的Embeddings集成 |
utils | 一些会话工具 |

code_interpreter:使用sandbox
指定代码沙盒环境,
默认 = auto,即自动调用沙盒环境执行代码。
设置 sandbox = none,不启用沙盒环境。
web_browser:使用web_browser
指定浏览器工具。
drawing_tool:使用drawing_tool
指定绘图工具。
