Setups

The requiring environment is as bellow:

• Linux
• Python 3+
• PyTorch 0.4.0
• Torchvision 0.2.0

Running Meta-Weight-Net on benchmark datasets (CIFAR-10 and CIFAR-100).

Here is an example:

python train_WRN-28-10_Meta_PGC.py --dataset cifar10 --corruption_type unif(flip2) --corruption_prob 0.6

The default network structure is WRN-28-10, if you want to train with ResNet32 model, please reset the learning rate delay policy.
