   Return a tensor with the same shape and contents as input.
tf.identity(
    input,
    name=None
)

  Used in the guide:

     * Eager execution

    For example:

import tensorflow as tf
val0 = tf.ones((1,), dtype=tf.float32)
a = tf.atan2(val0, val0)
a_identity = tf.identity(a)
print(a.numpy())          #[0.7853982]
print(a_identity.numpy()) #[0.7853982]

    Args:

     * input: A Tensor.
     * name: A name for the operation (optional).

    Returns:

   A Tensor. Has the same type as input.
