NDCG@K example code

[songsong0425]

Dear PyG community,

Hi, always thank you for your effort in package maintenance and development.
When I tried to implement the link prediction metrics (i.e., hits@k, ndcg@k), I couldn't find the example code for ndcg@k.
Can you consider adding the example about the ndcg@k for the evaluation metrics?
If it has already existed and I missed it, can anyone tell me where can I find it?

Thank you for reading!

It's currently true that we don't have great support for any more sophisticated link prediction metrics other than auprc or auroc. Which example would you like to see implement these metrics?

[songsong0425]

Sure. It will be great. Please feel free to update the related codes for it. :)

Can you take care of creating this issue for me? This would be highly appreciated.

Please forgive me for the late reply. I'm not familiar with Github, but is it correct that I need to create the issue by the Reference in new issue button?

[rusty1s]

Yes, that works. Alternatively, you can just create a new issue and link to here in its description.

As you suggested, I created the issue just now. Please check it and notify me if there is any problem. Thanks!
