Mask detect

This is my first machine learning project which is started at the start of cov-19
it may not be able to represent my skills now,
but it can demonstrate my learning abilities , skills of solving problems ,getting things done and overcoming difficulties
I was quite an amateur at that time
use pre-trained models don't konw how to optimize
learn and solve bugs from the internet
mark pictures with friends all nights
cool the computer with wet towels
now I have a better and systemic understanding of machine learning
but it is still one of the happiest and most exciting projects I did
