Best CIFAR-10, CIFAR-100 results with wide-residual networks using PyTorch

Pytorch Implementation of Sergey Zagoruyko's Wide Residual Networks

For Torch implementations, see here.

Requirements

See the installation instruction for a step-by-step installation guide. See the server instruction for server settup.

pip install http://download.pytorch.org/whl/cu80/torch-0.1.12.post2-cp27-none-linux_x86_64.whl
pip install torchvision
git clone https://github.com/meliketoy/wide-resnet.pytorch

How to run

After you have cloned the repository, you can train each dataset of either cifar10, cifar100 by running the script below.

python main --lr 0.1 resume false --net_type [lenet/vggnet/resnet/wide-resnet] --depth 28 --widen_factor 10 --dropout_rate 0.3 --dataset [cifar10/cifar100]
