Error stay very high before 100 epoch

[RocStone]

I simply download your code and run cifar100.py on K80 with
torch == 1.1.0
torchvision == 0.2.2
But the trian and test error is still high even having been trained by 100 epochs.
Did I do anything wrong?

I dont know well.
but i think you will get better result, by changing the following.
for example,(by using this optimizer)

optimizer = torch.optim.SGD(model.parameters(), lr=0.01, momentum=0.9, weight_decay=1e-5)

i think you will see quickly on the 1st epoch.

hello i have some questions .i can't run the cifar100.py becuase swish.py have some trouble.can you tell me what should i do ?
