説明

Description

Is there anything that needs to be done to make sure LightGCN is utilizing GPU's? I'm following this deep dive notebook here: https://github.com/microsoft/recommenders/blob/main/examples/02_model_collaborative_filtering/lightgcn_deep_dive.ipynb

My dataset is 1.4M users with about 13M interactions, a single epoch is taking about an hour. I have access to 4 GPU's, 192GB memory.

Thanks!
