ERROR(2):
shutil.Error: [('main/../requirements.txt', './output/cifar10/BBN.CIFAR10.res32.200epoch/codes/requirements.txt',
[Errno 13] Permission denied: './output/cifar10/BBN.CIFAR10.res32.200epoch/codes/requirements.txt'")]

I dont know whats the reason ,maybe is cuda's version? my computer is 3080 so it only can install cuda11
