python - Saw a small project waifu2x based on convolutional neural network to improve image resolution on github? ?

Question

I am new to machine learning. I would like to ask, after understanding the algorithm and related knowledge of this small project, how to write a small software like the one below and apply it in practice? ?

This is the link to github:
