Figuring out a Tensorflow lite model

So I have a tensorflow model that I basically don't know anything about, I'm weak reading Python and ML algorithms. I want to use this model in Kotlin or Java, but I know nothing about the inputs of the model nor the outputs. I want some help figuring out how to turn this model into something usable. If someone could help me with it it would be huge, and thank you. This is the repository : https://github.com/bastianwandt/RepNet
