2.2 LangChain基础知识

本目录对应课件 2.2 LangChain基础知识.md，文件按课件代码块顺序编号。

  • 01 到 04: Models
  • 05 到 09: Prompts
  • 10 到 11: Chains
  • 12 到 16: output_parsers
  • 17 到 18: Memory
  • 19 到 28: Indexes / Retrievers
  • 29 到 30: Agents

默认模型配置在上级目录 代码/.env。如需从 ModelVerse 切到本地 Ollama，将 MODEL_PROVIDER=openai 改为 MODEL_PROVIDER=ollama，并确认 Ollama 服务与模型已启动。
