Version dependence of pytorch

[gary-young]

Hi! This work is excellent so I want to reproduce the codes as soon as possible. However, when I try to reproduce the codes, I find there are some bugs such as the parameter mismatch when loading checkpoint:

checkpoint['model']['graph'] is expected to be a tensor or tensor-like but get a graph.Graph

After trying, I thought maybe it was related to the version of PyTorch. After rolling back the PyTorch version from 1.12.1 to 1.10.1 (and reinstalling the torch-scatter), the bug is solved. I believe if you are willing to test this issue and give some instructions, it can help more people who love this job like me.

Hi! Thanks for pointing this out. This is generally a compatibility issue between TorchDrug and PyTorch, since TorchDrug overloads a few PyTorch modules. We will test TorchDrug on newer PyTorch versions and fix that.
