Before Change

  if len(x.shape) < num_dims:
    return x
  return tf.reshape(x, [-1] + x.shape.as_list()[num_dims:])

After Change

  // Shape can"t be inferred statically.
  tensor_shape = tf.shape(x)
  leading_dim = tf.reduce_prod(tensor_shape[:num_dims], keepdims=True)
  other_dims = tensor_shape[num_dims:]
  dynamic_shape = tf.concat([leading_dim, other_dims], axis=0)
  result = tf.reshape(x, dynamic_shape)
  // We lose some static shape information from the above reduce/slice/concat
  // dance, so we explicitly pass it in from what we computed earlier.
