session is not available when using tensorflow 2.0 code example

Example: get_session` is not available when using TensorFlow 2.0.

Answer: In TF 2.0 you should use tf.compat.v1.Session() instead of tf.Session() Use the following code to get rid of the error in Tensorflow2.0:

import tensorflow as tf

tf.compat.v1.Session()
i.e. in your code above, replace this line self.sess = tf.compat.v1.keras.backend.get_session()of code with

self.sess = tf.compat.v1.Session()
