PyTorch models trained on CIFAR-10 dataset

  • 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.

How to use pretrained models

Automatically download and extract the weights from Box (933 MB)

python train.py --download_weights 1

Or 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 evaluation

If 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]

How to train models from scratch

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

How to test pretrained models

python train.py --test_phase 1 --pretrained 1 --classifier resnet18

Output

{'acc/test': tensor(93.0689, device='cuda:0')}
