Hello,
I wanted to try this solution for my own dataset that consists around 1 mln users and about 300k items (and about 42 mln interactions for training). Unfortunately, when I've prepared data fo…

This error was reported when I leveraged the C++ sampling program.
What should I do to use the C++ program on my own dataset?

Hello, thank you for your awesome graph learning library!
I am trying to implement [LightGCN](https://arxiv.org/abs/2002.02126) and use [LastFM dataset](https://pytorch-geometric.readthedocs.io/en/la…

我在lastfm上运行了代码中MHCN的模型，看到代码中实现的是s2-MHCN，但运行出的结果与论文中给出的实验数据有一定出入（如下：
Precision:0.19607427055702917
Recall:0.1991364574123199
F1:0.197593500708107
NDCG:0.24458583342484325

are there all the sampling methods mentioned in the paper? I only found the way of RNS.

在上一个问题我看到了“用户对物品的交互是按8:2随机划分到训练集和数据集”，我在切分movielen-1m也是这样切分的，然后用您的NGCF跑的时候，发现跑出来的Precision@10能达到0.5几，但movielen-1m一般这个值再好也应该只在0.15左右吧？但你的计算公式也没错... 所以我很疑惑，不知道到底哪里出问题了...

Can't wait to see the original implementation. I have implemented a version but it does not work well. Hope the codes can be released soon.
