After installing tensorflow 2.0, when using session, an error is reported: module ‘tensorflow’ has no attribute ‘session’:

Source code:

import tensorflow as tf
import os
with tf.Session() as sess:
    print("a:%i" % sess.run(a),"b:%i" % sess.run(b))
    print("Additionwithconstants:%i" % sess.run(a+b))
    print("Multiplicationwithconstant:%i" % sess.run(a*b))

Error message:

This method can solve this kind of problem, not only for session attribute

When running again, the program reported another error:

The reason is that version 2.0 is not compatible with version 1.0
