FileNotFoundError: Couldn't find any class folder in /data/xxx/ml-cvnets/dataset/ImageNet-1K/val.

I download the ImageNet1K datasets, after unzip the dataset, there are train/val/test folder, but only the train folder have class folder, how can i eval the val/test dataset? look forward your help,thanks.
