title: What is the output of tf.split?
body: <p>So assuming I have this:</p>
  
  <blockquote>
    <p>TensorShape([Dimension(None), Dimension(32)])</p>
  </blockquote>
  
  <p>And I use tf.split on this tensor _X with the dimension above:</p>
  
  <pre><code>_X = tf.split(_X, 128, 0) 
  </code></pre>
  
  <p>What is the shape of this new tensor? The output is a list so its hard to know the shape of this new tensor.</p>
