Jupyter Notebook(前身为 IPython Notebook)是一个基于 Web 的交互式计算环境,用于创建 notebook 文档。
本文档介绍如何将 Jupyter notebook (.ipynb) 中的数据加载为适合 LangChain 处理的格式。
from langchain_community.document_loaders import NotebookLoader
loader = NotebookLoader(
    "example_data/notebook.ipynb",
    include_outputs=True,
    max_output_length=20,
    remove_newline=True,
)
NotebookLoader.load().ipynb notebook 文件加载为 Document 对象。 参数
  • include_outputs (bool):是否在生成的文档中包含单元格输出(默认为 False)。
  • max_output_length (int):每个单元格输出中包含的最大字符数(默认为 10)。
  • remove_newline (bool):是否从单元格来源和输出中移除换行符(默认为 False)。
  • traceback (bool):是否包含完整的错误回溯(默认为 False)。
