Tensorflow: The Session graph is empty. Python

Hello guys I am using Tensorflow 2.0

and in these lines of code:

import tensorflow as tf
hello = tf.constant('Hello World')
sess = tf.compat.v1.Session()
sess.run(hello) <-- Error in this line

RuntimeError: The Session graph is empty. Add operations to the graph before calling run().

Any idea on how to solve it?

Solution 
  • g = tf.Graph() 
with g.as_default():   
  # Define operations and tensors in `g`.   
  hello = tf.constant('hello')   
  assert hello.graph is g
    
sess = tf.compat.v1.Session(graph=g) 
sess.run(hello)

    b'hello'
