You should add your code as well. I had the same Issue, but the cause was bug in my code, not of tensorflow.

[ravikyram]

You can try pip install gast==0.2.2 and see if it resolves your issue.

Please, go through the below link and see if it helps you.Thanks!

@ravikyram @2649
The problem has been resolved after installing gast. Thanks!

[che-shr-cat]

Got the same issue, it was resolved after installing gast 0.2.2. Previous gast version was 0.3.2
