 ## Data Preparation
 In `data/cifar10/train.txt`, we give an example to show how to prepare image training data. In `data/cifar10/test.txt` and `data/cifar10/database.txt`, the list of testing and database images could be processed during predicting procedure. If you want to add other datasets as the input, you need to prepare `train.txt`, `test.txt` and `database.txt` as CIFAR-10 dataset.
 
-We also recommend you to follow https://github.com/thuml/HashNet/tree/master/pytorch#datasets to prepare NUSWIDE_81 and COCO datasets.
