edge number of cora dataset ?

[yuxiaokang-source]

the cora_adj.npy shows cora dataset have 5278 edges

but the detail of this dataset(https://github.com/yueliu1999/Awesome-Deep-Graph-Clustering/blob/main/dataset/README.md)

shows this dataset have 5429 edges? why?

Thanks for your attention. The code counts the undirected edges. The dataset is exactly correct. The same statistics can be found in this link: https://github.com/stsfaroz/Graph-Convolutional-Networks-with-Cora-Dataset/blob/main/GCNN.ipynb.
