About metapath2vec on ogbn-mag

[hwangyeong]

Hello. I've tried using the metapath.py in the examples for ogbn-mag (examples/nodeproppred/mag/metapath.py). I kept the settings in your code unchanged. I found that the loss output remains the same every iteration. Also, I recorded the nodeembeddings of the paper type after each epoch, and they are all zeros. Here are the versions of the packages I'm using:
torch==1.11.0
torch_geometric==2.2.0
ogb==1.3.6
