A Simple Guide on How to Use the Python Logging Module

In the past, I use plain print() to display some statistics during training process of my models. However, it is not convenient to save the statistics in a file for later inspection. Once the program is finished, we do not have an overview of the training process. I am aware that there are packages such as tensorboardX and visdom, which are specifically designed for inspecting the various statistics during training. Right now, I would rather keep the program plain simple and usable. So I decided to give Python logging package a try.
