title: AttributeError: module 'tensorflow_core.keras.layers.experimental.preprocessing' has no attribute 'RandomFlip'
body: <p>I use Tensorflow 2.1.0
  In this code</p>
  <pre><code>data_augmentation = tf.keras.Sequential([
      tf.keras.layers.experimental.preprocessing.RandomFlip('horizontal'),
      tf.keras.layers.experimental.preprocessing.RandomRotation(0.3)
  ]) 
  </code></pre>
  <p>I find this error:</p>
  <pre><code>AttributeError: module 'tensorflow_core.keras.layers.experimental.preprocessing' has no attribute 'RandomFlip'
  </code></pre>
  <p>So how can I change it without changing version of tensorflow</p>
