A quick question here about cifar100

I am wondering if the cifar100 dataset of pytorch provide a way to get the coarse labels or if there is 3rd implemented codes to realize this.

I have refered to the manual of _torchvision.datasets.CIFAR100_, there seems to be no description about coarse labels.

Thanks in advance

No such option in torchvision.datasets.CIFAR100  
Solved by adding an option parameter to the code of [https://github.com/pytorch/vision/blob/master/torchvision/datasets/cifar.py](https://github.com/pytorch/vision/blob/master/torchvision/datasets/cifar.py)  
See the modified code at [https://github.com/xiaodongww/pytorch/blob/master/cifarDataset.py](https://github.com/xiaodongww/pytorch/blob/master/cifarDataset.py)

I’m not sure, but it should be easy to implement a map from [https://www.cs.toronto.edu/~kriz/cifar.html](https://www.cs.toronto.edu/~kriz/cifar.html).

Thanks for your quick reply.  
I have just check the source code and there is no such option.

Just handled this by simply modifying the source code a little by adding a coarse\_labels key.
