langchain_community.document_loaders.unstructured.UnstructuredFileIOLoader¶

class langchain_community.document_loaders.unstructured.UnstructuredFileIOLoader(file: Union[IO, Sequence[IO]], mode: str = 'single', **unstructured_kwargs: Any)[source]¶

Load files using Unstructured.

The file loader uses the unstructured partition function and will automatically detect the file type. You can run the loader in one of two modes: “single” and “elements”. If you use “single” mode, the document will be returned as a single langchain Document object. If you use “elements” mode, the unstructured library will split the document into elements such as Title and NarrativeText. You can pass in additional unstructured kwargs after mode to apply different unstructured settings.

Examples

from langchain_community.document_loaders import UnstructuredFileIOLoader

with open(“example.pdf”, “rb”) as f:
loader = UnstructuredFileIOLoader(

f, mode=”elements”, strategy=”fast”,

) docs = loader.load()
