Yes the divergence between training loss and testing loss looks like an overfitting scenario. . An example could be a feature matrix where for every author we have information about being involved in a certain paper . I think the main reason that in the Pytorch Geometric examples simply the output of all nodes are computed is a different one to the "no slicing of data issue" raised in the other answer. The PyTorch geometric hyperparameter tuning is defined as a parameter that passes as an argument to the constructor of the estimator classes. First build a Conda environment containing PyTorch as described above then follow the steps below. >@inproceedings {rozemberczki2021pytorch, author = {Benedek .
