PaddlePaddle Fast ImageNet can train ImageNet dataset with fewer epochs. We implemented the it according to the blog
[Now anyone can train Imagenet in 18 minutes](https://www.fast.ai/2018/08/10/fastai-diu-imagenet/) which published on the [fast.ai] website.
PaddlePaddle Fast ImageNet using the dynmiac batch size, dynamic image size, rectangular images validation and etc... so that the Fast ImageNet can achieve the baseline
(acc1: 75%, acc5: 93%) by 27 epochs on 8 * V100 GPUs.
(acc1: 75.9%, acc5: 93.0%) at 26 epochs on 8 * V100 GPUs.
