How to download large files (like weights of a model) from Colaboratory?

问题

I have tried downloading small files from google Colaboratory. They are easily downloaded but whenever I try to download files which have a large sizes it shows an error? What is the way to download large files?

回答1:

This is how I handle this issue:

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

auth.authenticate_user()

Then click on the link, authorize Google Drive and paste the code in the notebook.

drive_service = build('drive', 'v3')

def save_file_to_drive(name, path):
    file_metadata = {
      'name': name,
      'mimeType': 'application/octet-stream'
     }

     media = MediaFileUpload(path, 
                    mimetype='application/octet-stream',
                    resumable=True)

     created = drive_service.files().create(body=file_metadata,
                                   media_body=media,
                                   fields='id').execute()

     print('File ID: {}'.format(created.get('id')))

     return created

Then:

save_file_to_drive(destination_name, path_to_file)

This will save whatever files to your Google Drive, where you can download or sync them or whatever.

Google colab doesn't allow you to download large files using files.download(). But you can use one of the following methods to access it:

1. The easiest one is to use github to commit and push your files and then clone it to your local machine.
2. You can mount google-drive to your colab instance and write the files there.
