python-tensorflowHow do I write a Python TensorFlow example code?

Example code

import tensorflow as tf

# Create a constant op
# This op is added as a node to the default graph
hello = tf.constant("Hello, TensorFlow!")

# start a TF session
sess = tf.Session()

# run the op and get result
print(sess.run(hello))

Output example

b'Hello, TensorFlow!'

This example code creates a constant op and adds it to the default graph. It then starts a TensorFlow session and runs the op to get the result.

The code consists of four parts:

1. import tensorflow as tf: This imports the TensorFlow library as the tf object.

2. hello = tf.constant("Hello, TensorFlow!"): This creates a constant op with the string "Hello, TensorFlow!" and assigns it to the hello variable.

3. sess = tf.Session(): This creates a TensorFlow session and assigns it to the sess variable.

4. print(sess.run(hello)): This runs the hello op in the sess session and prints the result.

For more information on TensorFlow and how to write example code, please see the TensorFlow documentation.
