title: How to use tf.random.uniform and not generate duplicates
body: <p>I need to creare a random list of integer values that rappresent indices for other operation, the problem is that <code>tf.random.uniform</code> can generate the same value multiple times, and i don't want this behavious. Is there a way to change it?</p>
  <pre><code>indices = tf.random.uniform(shape=[size_for_layer_submodel[index], ], minval=0,
                                  maxval=size_for_layer[index], dtype=tf.dtypes.int64, seed=seed, name=None)
  </code></pre>
