I\'ve been pickling the objects to filesystem and reading them back when needed to work with those objects. Currently I\'ve this code for that purpose.
Instead of open() use cloudstorage.open() (or gcs.open() if importing cloudstorage as gcs, as in the above-mentioned doc) and note that the full filepath starts with the GCS bucket name (as a dir).
More details in the cloudstorage.open() documentation.
