A Simple Hello World in TensorFlow

We are first importing TensorFlow library with following code:

import tensorflow as tf

Then creating a constant with the following code:

msg = tf.constant('Say Hello to TensorFlow!')

Constants value cannot be modified once created. Then creating an instance of TensorFlow session with following code:

sess = tf.Session()

• The tf.Session() is a session management class in TensorFlow which is responsible for running the TensorFlow operations.
• To run the TensorFlow operations we will use the method sess.run() as shown below:

print(sess.run(msg))

Complete Program

#TensorFlow Hello World example
#import tensorflow libraries
import tensorflow as tf
#create constant
msg = tf.constant('Say Hello to TensorFlow!')
#create session to run 
sess = tf.Session()
print(sess.run(msg))
