In which environment did this code work?

[UdonDa]

Hello. Mr. Cameron Fabbri.
I am a Japanese university second grader and I wanted to move this code.
However, because the environment was not written, I was confused as to which environment to move and I made Issue.
If you do not mind, could you tell me the environment of this code?

Hi. By environment, do you mean OS? I was using Ubuntu 16.04 with Python 2.7 and Tensorflow version 1.4.
