QUESTION
I have highly unbalanced data in a two class problem that I am trying to use TensorFlow to solve with a NN. I was able to find a posting that exactly described the difficulty that I'm having and gave a solution which appears to address my problem. However I'm working with an assistant, and neither of us really knows python and so TensorFlow is being used like a black box for us. I have extensive (decades) of experience working in a variety of programming languages in various paradigms. That experience allows me to have a pretty good intuitive grasp of what I see happening in the code my assistant cobbled together to get a working model, but neither of us can follow what is going on enough to be able to tell exactly where in TensorFlow we need to make edits to get what we want.
I'm hoping someone with a good knowledge of Python and TensorFlow can look at this and just tell us something like, "Hey, just edit the file called xxx and at the lines at yyy," so we can get on with it.
Below, I have a link to the solution we want to implement, and I've also included the code my assistant wrote that initially got us up and running. Our code produces good results when our data is balanced, but when highly imbalanced, it tends to classify everything skewed to the larger class to get better results.
Here is a link to the solution we found that looks promising:
Loss function for class imbalanced binary classifier in Tensor flow
I've included the relevant code from this link below. Since I know that where we make these edits will depend on how we are using TensorFlow, I've also included our implementation immediately under it in the same code block with appropriate comments to make it clear what we want to add and what we are currently doing:

No vulnerabilities reported
Install Binary-Classifier
You can use Binary-Classifier like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
