- I modified TorchVision official implementation of popular CNN models, and trained those on CIFAR-10 dataset.
- I changed number of class, filter size, stride, and padding in the the original code so that it works with CIFAR-10.
- I also share the weights of these models, so you can just load the weights and use them.
- The code is highly re-producible and readable by using PyTorch-Lightning.

Automatically download and extract the weights from Box (933 MB)
python train.py --download_weights 1Or use Google Drive backup link (you have to download and extract manually)
Load model and run
from cifar10_models.vgg import vgg11_bn, vgg13_bn, vgg16_bn, vgg19_bn
# Untrained model
my_model = vgg11_bn()
# Pretrained model
my_model = vgg11_bn(pretrained=True)
my_model.eval() # for evaluationIf you use your own images, all models expect data to be in range [0, 1] then normalized by
mean = [0.4914, 0.4822, 0.4465]
std = [0.2471, 0.2435, 0.2616]Check the train.py to see all available hyper-parameter choices.
To reproduce the same accuracy use the default hyper-parameters
python train.py --classifier resnet18
python train.py --test_phase 1 --pretrained 1 --classifier resnet18
