some of my questions

[lihang2256]

I want to know that when I run this project, like Epoch: [0][ 400/80073] Time 0.315 ( 0.372) Data 0.002 ( 0.073) Loss 6.9802e+00 (7.0827e+00) Acc@1 0.00 ( 0.08) Acc@5 6.25 ( 0.55) lr 0.000000 (0.000002) what does it mean out and in () of Acc@1 and Acc@5, besides, sometimes Acc@5 may exceed 1.0. My ViT network Acc@1 has only 0.15, is it normal?
