Running "bash run_celebahq_bpda_glasses.sh" on celeba-HQ,

I get this result:

Attack 50 of 50   Batch defended: 1 of 2
finished 0-th batch in attack_all
init acc: 50.00%, robust acc: 50.00%, time elapsed: 24673.68s
x_adv_sde shape: torch.Size([2, 3, 256, 256])

What does 50% mean? Anything went wrong?
