mini_imagenet 数据集生成工具

最近在看小样本方面的论文，发现这个mini_imagenet这个数据集比较常用，但是却不好找，找了半天也没有找到，最后在找到了这样的答案：

小样本学习（Few shot learning）标准数据集（miniImageNet、tieredImageNet、Fewshot-CIFAR100）下载地址

顺着这个线索我又找到了一个miniImageNet数据集生成的工具：

https://gitee.com/devilmaycry812839668/mini-imagenet-tools

读了读这个代码，感觉虽然代码质量一般但是可以使用，为了节省时间也就使用这个代码好了。

个人使用的数据生成命令：

python mini_imagenet_generator.py --tar_dir ~/ILSVRC2012/ILSVRC2012_img_train.tar

更多命令参考项目页面。

通过这个代码才知道原来 miniImageNet的数据集是在ImageNet数据集的基础上进行划分的，换句话说miniImageNet数据集是ImageNet数据集的子集。如果自己想要从头获得这个miniImageNet数据集需要先下载ImageNet数据集，ImageNet数据集的下载方式前文已介绍。

miniImageNet数据集是在ImageNet数据集（ILSVRC2012_img_train.tar）基础上提取出100个类：
