TensorFlow example to print Hello, TensorFlow

We will do an example using TensorFlow directly in the Python shell. In this example, we will print Hello, TensorFlow using TensorFlow.

1. Invoke Python from your shell by typing the following in the command prompt:

         python3

2. Import the tensorflow library by entering the following command:

        >>> import tensorflow as tf

3. Next, define a constant with the string Hello, TensorFlow. This is different from the usual Python assignment operations as the value is not yet initialized:

        >>> hello = tf.constant('Hello, TensorFlow!') 

4. Create a session to initialize the computational graph, and give a name to the session:

        >>> session = tf.Session() 

The session can be run with the variable hello as the parameter. ...
