TensorFlow example for adding two numbers

Here is another simple example of how TensorFlow is used to add two numbers.

1. Create a Python file and import tensorflow using the following code:

        import tensorflow as tf

The preceding import will be necessary for all the latter examples. It is assumed that the reader has imported the library for all the examples. A placeholder can be defined in the following manner. The placeholders are not loaded when assigned. Here, a variable is defined as a placeholder with a type of float32. A placeholder is an empty declaration and can take values when a session is run.

2. Now we define a placeholder as shown in the following code:

        x = tf.placeholder(tf.float32)        y = tf.placeholder(tf.float32)

3. Now the sum ...
