About some problems encountered in the training process

[IWDG1]

Thank you very much for the open source, but I am having some problems with the training:
1, I looked at the training code, the whole training process is only traversing the training data set once (that is, 200000 + 58000)? But when I got to 201000, I finished the training directly without any error report, is this normal?

2, I noticed in your paper that you use the remaining 12,000 FFHQ images for evaluation, but I can't find the evaluation code and dataset, the parameter val_interval is not used, how should I evaluate my trained model?
