Hi! I Am Trying To Download Data From Gs Using

Hi! I am trying to download data from GS using StorageManager.get_local_copy() . It works fine when I point it to a file i.e gs://bucket/dataset/image.png but fails if I want to download the whole dir gs://bucket/dataset . It prints a 404 error with a link that redirects to a http://storage.googlepis.com message: “Anonymous caller does not have storage.objects.get access to the Google Cloud Storage object.”

AgitatedDove14 update here! Something like this should work:
from trains import StorageManager from trains.storage.helper import StorageHelper bucket = 'gs://bucket' helper = StorageHelper.get(bucket) remote_files = helper.list('folder') for f in remote_files: StorageManager.get_local_copy(bucket + "/" + f)the * gives [] results since one the list method startswith is used which uses it as a string and not as a wildcard

Hi GrievingTurkey78 ,
Yes this is a per file download, but I think you can list the bucket and download everything
Try:
from trains import StorageManager from trains.storage.helper import StorageHelper helper = StorageHelper.get('gs://bucket/folder') remote_files = helper.list('*') for f in remote_files: StorageManager.get_local_copy(f)

You might need to play around a bit, it might be that StorageHelper.get(' gs://bucket ') and then helper.list('folder/*')
Let me know what worked 🙂

Maybe we should add it to Storage Manager? What do you think?
