I can't mount my another drive in Google Colab

Question

I tried to mount my drive in Google Colab, but, I can't do it because of credential error.

I want to mount another drive different from the one I am using in Google Colab.

The following is my commands.

from google.colab import drive
drive.mount('/content/drive')

The following is the part of question.

I could mount another drive yesterday to do the same method.

What is the solution?

Answer 1

I solved this problem with this link. The following is the correct code:

from google.colab import drive  
drive._mount('/content/drive')  

Here is the screenshot of the code:

Answer 2

As of now (26th January 2022), you can not mount another drive with different goggle account in Colab with drive.mount() or drive._mount(). Previously it could be done.

Now, You may use gdrive package instead. Check my detailed answer in this thread

Answer 3

Update: From Mars 30, 2022, my old solution isn't working! I find another solution (Phillip's solution) that is working now.

Phillip's Solution:

This solution is based on Phillip's post. You can follow his post for more information.

Follow these steps:

1. Run the below code:

!sudo add-apt-repository -y ppa:alessandro-strada/ppa 2>&1 > /dev/null
!sudo apt-get update -qq 2>&1 > /dev/null
!sudo apt -y install -qq google-drive-ocamlfuse 2>&1 > /dev/null
!google-drive-ocamlfuse

2. From the previous step, you get an error like this. Click on the link that locates in the previous error message and authenticate your account.

Failure("Error opening URL:https://accounts.google.com/o/oauth2/auth?client_id=... ")

3. Run the below code:

!sudo apt-get install -qq w3m # to act as web browser 
!xdg-settings set default-web-browser w3m.desktop # to set default browser
%cd /content
!mkdir drive
%cd drive
!mkdir MyDrive
%cd ..
%cd ..
!google-drive-ocamlfuse /content/drive/MyDrive

You must get this message:

Access token retrieved correctly.

My Old Solution

!apt-get install -y -qq software-properties-common python-software-properties module-init-tools
!add-apt-repository -y ppa:alessandro-strada/ppa 2>&1 > /dev/null
!apt-get update -qq 2>&1 > /dev/null
!apt-get -y install -qq google-drive-ocamlfuse fuse
from google.colab import auth
auth.authenticate_user()
from oauth2client.client import GoogleCredentials
creds = GoogleCredentials.get_application_default()
import getpass
!google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret} < /dev/null 2>&1 | grep URL
vcode = getpass.getpass()
!echo {vcode} | google-drive-ocamlfuse -headless -id={creds.client_id} -secret={creds.client_secret}
%cd /content
!mkdir drive
%cd drive
!mkdir MyDrive
%cd ..
%cd ..
!google-drive-ocamlfuse /content/drive/MyDrive
