langchain_community.document_loaders.gcs_file.GCSFileLoader¶

class langchain_community.document_loaders.gcs_file.GCSFileLoader(project_name: str, bucket: str, blob: str, loader_func: Optional[Callable[[str], BaseLoader]] = None)[source]¶

Load from GCS file.

Initialize with bucket and key name.

Parameters

  • project_name (str) – The name of the project to load

  • bucket (str) – The name of the GCS bucket.

  • blob (str) – The name of the GCS blob to load.

  • loader_func (Optional[Callable[[str], BaseLoader]]) – A loader function that instantiates a loader based on a file_path argument. If nothing is provided, the UnstructuredFileLoader is used.

Examples

To use an alternative PDF loader: >> from from langchain_community.document_loaders import PyPDFLoader >> loader = GCSFileLoader(…, loader_func=PyPDFLoader)

To use UnstructuredFileLoader with additional arguments: >> loader = GCSFileLoader(…, >> loader_func=lambda x: UnstructuredFileLoader(x, mode=”elements”))
