The difference between this code and the paper "IDDPM" in the run_loop function in train_util.py.

Thanks for this creative work.

But I don't understand why it was added to the run_loop() function, since batch_eval and cond_eval don't seem to be used.
Secondly, why are the values ​​of the parameters lr_anneal_steps (200000) and save_interval (50000) in the run_loop() function so large.
