no module named compat.v1

[aozorahime]

I am trying running ./train_segan.sh however I got the error "no module name compat.v1" on main.py. I am running this code on CPU with different requirements python version 2.7 and Tensorflow version is 0.12.1. I believe this could be the TensorFlow version, I had tried the upgrade version such as 1.14v, 1.15v, and 2.1.0v but still got the same error. Do you have any suggestions or should I move to run on GPU instead?
