Hi, thanks so much for reading. Yes, the article covers the basics, then you will have to apply it to something interesting, like blinking eye detection, if you want to build some effects at the style of Snapchat, or anything else you have in mind.
By debugging it depends what you mean, are you talking about debugging the quality of the model? or to test or validate the model? or are you talking about debugging how the library works internally?
If it’s the first, I never went that way. I used models that are already trained. As per the second, it can be a bit painful to set up, but it is possible to debug if you build the library in debug mode.
Have done it, I don’t recommend it…
