GCSFileLoader#

class langchain_google_community.gcs_file.GCSFileLoader(project_name: str, bucket: str, blob: str, loader_func: Callable[[str], BaseLoader] | None = 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 (Callable[[str], BaseLoader] | None) – 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”))
