This covers how to load document objects from an Google Cloud Storage (GCS) directory.

In [1]:

from langchain.document_loaders import GCSDirectoryLoader

In [2]:

# !pip install google-cloud-storage

In [3]:

loader = GCSDirectoryLoader(project_name="aist", bucket="testing-hwc")

In [4]:

loader.load()

Specifying a prefix

You can also specify a prefix for more finegrained control over what files to load.

In [6]:

loader = GCSDirectoryLoader(project_name="aist", bucket="testing-hwc", prefix="fake")

In [7]:

loader.load()
