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

TF2 runs Eager Execution by default  thus removing the need for Sessions  If you want to run static graphs  the more proper way is to use tf function   in TF2  While Session can still be accessed via tf compat v1 Session   in TF2  I would discourage using it  It may be helpful to demonstrate this difference by comparing the difference in hello worlds   TF1 x hello world   import tensorflow as tf msg   tf constant  Hello  TensorFlow    sess   tf Session   print sess run msg     TF2 x hello world   import tensorflow as tf msg   tf constant  Hello  TensorFlow    tf print msg    For more info  see Effective TensorFlow 2

For TF2 x  you can do like this  import tensorflow as tf with tf compat v1 Session   as sess      hello   tf constant  hello world       print sess run hello     gt  gt  gt  b hello world

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

Tensorflow 2 x support s Eager Execution by default hence Session is not supported

User · Answer

TF v2 0 supports Eager mode vis-a-vis Graph mode of v1 0  Hence  tf session   is not supported on v2 0  Hence  would suggest you to rewrite your code to work in Eager mode

Same problem occurred for me import tensorflow as tf hello   tf constant  Hello World     sess   tf compat v1 Session         I got the error on this step when I used                                     tf Session    sess run hello   Try replacing it with tf compact v1 Session

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
