问题
When I am executing the command sess = tf.Session() in Tensorflow 2.0 environment, I am getting an error message as below:
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: module 'tensorflow' has no attribute 'Session'
System Information:
- OS Platform and Distribution: Windows 10
- Python Version: 3.7.1
- Tensorflow Version: 2.0.0-alpha0 (installed with pip)
Steps to reproduce:
Installation:
- pip install --upgrade pip
- pip install tensorflow==2.0.0-alpha0
- pip install keras
- pip install numpy==1.16.2
Execution:
- Execute command: import tensorflow as tf
- Execute command: sess = tf.Session()

According to TF 1:1 Symbols Map, in TF 2.0 you should use tf.compat.v1.Session() instead of tf.Session()
https://docs.google.com/spreadsheets/d/1FLFJLzg7WNP6JHODX5q8BDgptKafq_slHpnHVbJIteQ/edit#gid=0
To get TF 1.x like behaviour in TF 2.0 one can run
import tensorflow.compat.v1 as tf
tf.disable_v2_behavior()
but then one cannot benefit of many improvements made in TF 2.0. For more details please refer to the migration guide https://www.tensorflow.org/guide/migrate

I faced this problem when I first tried python after installing windows10 + python3.7(64bit) + anacconda3 + jupyter notebook.
I solved this problem by refering to "https://vispud.blogspot.com/2019/05/tensorflow200a0-attributeerror-module.html"
I agree with
I believe "Session()" has been removed with TF 2.0.
I inserted two lines. One is tf.compat.v1.disable_eager_execution() and the other is sess = tf.compat.v1.Session()
My Hello.py is as follows:
import tensorflow as tf
tf.compat.v1.disable_eager_execution()
hello = tf.constant('Hello, TensorFlow!')
sess = tf.compat.v1.Session()
print(sess.run(hello))

TF 2.0 hello world:
import tensorflow as tf
msg = tf.constant('Hello, TensorFlow!')
tf.print(msg)

If this is your code, the correct solution is to rewrite it to not use Session(), since that's no longer necessary in TensorFlow 2
If this is just code you're running, you can downgrade to TensorFlow 1 by running
pip3 install --upgrade --force-reinstall tensorflow-gpu==1.15.0
(or whatever the latest version of TensorFlow 1 is)
