fix depth of resnet/preresnet on cifar10/cifar100
Latest commit 24f1c45 Jan 23, 2019


Classification on CIFAR-10/100 and ImageNet with PyTorch.


  • Unified interface for different network architectures
  • Multi-GPU support
  • Training progress bar with rich info
  • Training log and training curve visualization code (see ./utils/


  • Install PyTorch
  • Clone recursively
    git clone --recursive


Please see the Training recipes for how to train the models.



Top1 error rate on the CIFAR-10/100 benchmarks are reported. You may get different results when training your models with different random seed. Note that the number of parameters are computed on the CIFAR-10 dataset.

Supported Architectures

CIFAR-10 / CIFAR-100

Since the size of images in CIFAR dataset is 32x32, popular network structures for ImageNet need some modifications to adapt this input size. The modified models is in the package models.cifar:
