如何通过 Google Colab notebook (.ipynb) 访问 Google Drive 上的文件？

Question

I have uploaded all the files I need to train (fine-tune) an object detection model on my Google Drive account. There, I have opened an ipynb file via google colab and I need to run some scripts to initialize things and run training.

But I ran into a problem of not knowing how to access the files that I uploaded from the notebook. The notebook is created in the same directory of the scripts that I need to run.

When I execute !ls I get only one datalab folder in return, and !pwd returns /content .

I want to know if there's a way to access all the files I have uploaded to my google drive account. I may be doing the wrong thing trying to train a model this way, but I don't know any other. So, please help :).

Thank you in advance.

Here what I use to download a file from Google Drive to Google Colab file system, substitute fileId value with your Drive file id.

!pip install -U -q PyDrive

from pydrive.auth import GoogleAuth
from pydrive.drive import GoogleDrive
from google.colab import auth
from oauth2client.client import GoogleCredentials

auth.authenticate_user()
gauth = GoogleAuth()
gauth.credentials = GoogleCredentials.get_application_default()
drive = GoogleDrive(gauth)

fileId = '1234567890dcz4qL-JQtYqX9ZXUt7JXe'
fileName = fileId
downloaded = drive.CreateFile({'id': fileId})
downloaded.GetContentFile(fileName)

To get Drive file id look at this answer .
