My problem was the tutorial was successful but I wanted to modify tutorial algorithm so that my dataset can be trained.
Tensorflow algorithm was well stable and structured algorithm.
But MNIST dataset was too many for me to modify and test the algorithm.
Therefore I found simple and intuitive but modify-needed algorithm.
The tutorial was using pokemon images and tried to train them with GAN.
I modified epoch size, batch size, and sample data size to show the results in a short time. One epoch took about a minute.
The result of tutorial was successful.
