Google Drive

This notebook walks through connecting a LangChain to the Google Drive API.

Prerequisites​

  1. Create a Google Cloud project or use an existing project
  2. Enable the Google Drive API
  3. Authorize credentials for desktop app
  4. pip install --upgrade google-api-python-client google-auth-httplib2 google-auth-oauthlib

Instructions for retrieving your Google Docs data​

By default, the GoogleDriveTools and GoogleDriveWrapper expects the credentials.json file to be ~/.credentials/credentials.json, but this is configurable using the GOOGLE_ACCOUNT_FILE environment variable. The location of token.json use the same directory (or use the parameter token_path). Note that token.json will be created automatically the first time you use the tool.

GoogleDriveSearchTool can retrieve a selection of files with some requests.

By default, If you use a folder_id, all the files inside this folder can be retrieved to Document, if the name match the query.

%pip install --upgrade --quiet  google-api-python-client google-auth-httplib2 google-auth-oauthlib langchain-community

You can obtain your folder and document id from the URL:

The special value root is for your personal home.

folder_id = "root"
# folder_id='1yucgL9WGgWZdM1TOuKkeghlPizuzMYb5'

By default, all files with these mime-type can be converted to Document.

  • text/text
  • text/plain
  • text/html
  • text/csv
  • text/markdown
  • image/png
  • image/jpeg
  • application/epub+zip
  • application/pdf
  • application/rtf
  • application/vnd.google-apps.document (GDoc)
  • application/vnd.google-apps.presentation (GSlide)
  • application/vnd.google-apps.spreadsheet (GSheet)
  • application/vnd.google.colaboratory (Notebook colab)
  • application/vnd.openxmlformats-officedocument.presentationml.presentation (PPTX)
  • application/vnd.openxmlformats-officedocument.wordprocessingml.document (DOCX)

It's possible to update or customize this. See the documentation of GoogleDriveAPIWrapper.

But, the corresponding packages must installed.

%pip install --upgrade --quiet  unstructured
from langchain_googledrive.tools.google_drive.tool import GoogleDriveSearchTool
from langchain_googledrive.utilities.google_drive import GoogleDriveAPIWrapper

# By default, search only in the filename.
tool = GoogleDriveSearchTool(
    api_wrapper=GoogleDriveAPIWrapper(
        folder_id=folder_id,
        num_results=2,
        template="gdrive-query-in-folder",  # Search in the body of documents
    )
)
import logging

logging.basicConfig(level=logging.INFO)
tool.run("machine learning")
tool.description
from langchain.agents import load_tools

tools = load_tools(
    ["google-drive-search"],
    folder_id=folder_id,
    template="gdrive-query-in-folder",
)
API Reference:load_tools

Use within an Agent​

from langchain.agents import AgentType, initialize_agent
from langchain_openai import OpenAI

llm = OpenAI(temperature=0)
agent = initialize_agent(
    tools=tools,
    llm=llm,
    agent=AgentType.STRUCTURED_CHAT_ZERO_SHOT_REACT_DESCRIPTION,
)
agent.run("Search in google drive, who is 'Yann LeCun' ?")
