title: Fail to fetch the *celeb_a* dataset from the *tensorflow_datasets* library (in python)
body: <p>When trying to fetch the <em>celeb_a</em> dataset from the <em>tensorflow_datasets</em> library, the URL is said to be wrong. That's my <strong>python</strong> code:</p>
  <pre><code>! pip install tensorflow                # done today
  ! pip install tensorflow-datasets       # done today
  import tensorflow as tf
  import tensorflow_datasets as tfds
  celeba_bldr = tfds.builder('celeb_a')   # it does work
  # I can see all the features ('image', 'landmarks', 'attributes).
  celeba_bldr.download_and_prepare()      # it does NOT work
  </code></pre>
  <p>I get this error message:</p>
  <pre><code>DownloadError: Failed to get url https://drive.google.com/uc?export=download&amp;id=0B7EVK8r0v71pZjFTYXZWM3FlRnM. HTTP code: 404.
  </code></pre>
  <p>and actually the url is unreachable.
  Unfortunately, <strong>I cannot change the URL</strong>, as it's embedded in the tensorflow code.
  What can I do, please?</p>
  <p>This is my python version: 3.8.8 (default, Apr 13 2021, 15:08:03) [MSC v.1916 64 bit (AMD64)]</p>
  <p>At the beginning of the execution, the method <em>celeba_bldr.download_and_prepare()</em> shows this:</p>
  <pre><code>Downloading and preparing dataset Unknown size (download: Unknown size, generated: Unknown size, total: Unknown size)
