Hello author, I directly run the grafting.py file, the cifar10 dataset, and can't train normally, may I ask you, what should I do

[a1037441813]

Running grafting.py directly cannot train all the time

The training will only go to epoch 0, then pause, and show that it has been stuck in the time.sleep (10) statement. . .
May I ask the author
What is the normal training procedure, and where is my problem. . . Thank you
