# Train various models on CIFAR10 with Chainer

## Requirements

- Python 3.5.1+ (not tested with Python2)

- pip packages:

    - chainer>=3.1.0

    - chainercv>=0.8.0

```

## About data augmentation

It performs various data augmentation using [ChainerCV](https://github.com/chainer/chainercv). Provided operations are:

- Random rotating (using OpenCV or scikit-image)

- Random lighting

- Random LR-flipping

- Random zomming (a.k.a. expansion)

- Random cropping

See the details at `transform` function in `train.py`.
