Workaround for failing TFDS library for loading the public dataset, Celeb A.
As of Dec-3 2021, the TFDS Celeb A dataset gives an wrong checksum error
when trying to use tfds.load("celeb_a") and this library is a workaround
using a mirror of the img_align_celeba dataset on S3.
You can use this from within Colab using the following methods:
!pip install git+https://github.com/yarri-oss/celeba_backup.git
!pip install tfds_nightly
import tensorflow as tf
tf.__version__ # should be 2.7.0
import tensorflow_datasets as tfds
import celeba_backup
ds = tfds.load('celeba_backup', split='train')
