Tiny ImageNet是ImageNet的子集,ImageNet太大了,训练一次要好几天,于是准备用Tiny ImageNet代替ImageNet.
/mmpretrain/mmpretrain/datasets/imagenet.py里面列出了ImageNet的两种格式:
imagenet├── train│ ├──class_x| | ├── x1.jpg| | ├── x2.jpg| | └── ...│ ├── class_y| | ├── y1.jpg| | ├── y2.jpg| | └── ...| └── ...├── val│ ├──class_x| | └── ...│ ├── class_y| | └── ...| └── ...└── test├── test1.jpg├── test2.jpg└── ...
或者:
imagenet├── train│ ├── x1.jpg│ ├── y1.jpg│ └── ...├── val│ ├── x3.jpg│ ├── y3.jpg│ └── ...├── test│ ├── test1.jpg│ ├── test2.jpg│ └── ...└── meta├── train.txt└── val.txt
编写一个python小程序将解压后的Tiny ImageNet转化为上面两种格式种的任意一种即可:
修改/mmpretrain/mmpretrain/datasets/categories.py文件,在里面加上下面的类列表:

最后,将相关模型文件里面的num_classes从1000改成200,就可以运行了.
