I want to run this on Tensorflow 2.0

[Confidence9898]

Hello
Nice to meet you.
I should perform multi-person face tracking project, and I think it is really good demo for my project.
So I want to study something from this repository, but I can't run this on Tensorflow 2.0.
Of courrse I know that this is for Tensorflow 1.0 but not for Tensorflow 2.0.
However I am using Tensorflow 2.0 and it is necessary to run on 2.0.
So would you help me to run this project on Tensorflow 2.0?

Thank you
