Google Drive file retrieval in Colab notebook throws undefined service error

I’m having trouble accessing files from Google Drive in my Colab environment

I keep getting a NameError when trying to fetch a file from my Google Drive. Here’s what I’m attempting:

document_id = '1zRx9mKpLqWeRtYuO3nEF-x_M7rN4VkLm'

import io
from googleapiclient.http import MediaIoBaseDownload

file_request = gd_service.files().get_media(fileId=document_id)
file_buffer = io.BytesIO()
file_downloader = MediaIoBaseDownload(file_buffer, file_request)
finished = False
while not finished:
    progress, finished = file_downloader.next_chunk()

file_buffer.seek(0)
print('File content: {}'.format(file_buffer.read()))

The error message I’m seeing is:

NameError: name 'gd_service' is not defined

What am I missing here? How do I properly set up the service connection?

u gotta make sure gd_service is defined first. usually, it’s built using build('drive', 'v3', ...) after auth. check if you’ve done that, and import the right packages, like you might’ve missed google.auth or something.

You’re encountering the error because gd_service is not defined in your code. To resolve this, you must first authenticate and create the service object. You can do this with the following code snippet:

from google.colab import auth
from googleapiclient.discovery import build

auth.authenticate_user()
service = build('drive', 'v3')

Afterward, replace gd_service with service in your script. Proper authentication is essential in Colab, as it initiates the OAuth flow for Drive API access. Omitting this step will result in the continued NameError.
