Errors in Runing the code

[ans92]

Hi @donhk1011
Thank you for the great work and this code. I am trying to run the code on Google colab with tensorflow 1.13.1 and python 3 but the code is giving me following errors:

I think that would probably because of tensorflow version and python version. Therefore do you have code compatible with python 3 and some above version of tensorflow? Could you please help me in this regard? Thank you.
