Tsv 集成

使用 LangChain Python 与 Tsv 文档加载器集成。

制表符分隔值（TSV）文件是一种用于存储表格数据的简单、基于文本的文件格式。记录由换行符分隔，记录内的值由制表符分隔。

UnstructuredTSVLoader

你也可以使用 UnstructuredTSVLoader 来加载表格。使用 UnstructuredTSVLoader 的一个优点是，如果你在 "elements" 模式下使用它，表格的 HTML 表示将可在元数据中找到。

from langchain_community.document_loaders.tsv import UnstructuredTSVLoader

loader = UnstructuredTSVLoader(
    file_path="./example_data/mlb_teams_2012.csv", mode="elements"
)
docs = loader.load()

print(docs[0].metadata["text_as_html"])
