How to run
-------

> **_NOTE:_**  `train.py` is deprecated and please check the new version in `//examples/core/gat/train.py`.

Run with the following for multiclass node classification (available datasets: "cora", "citeseer", "pubmed")
```bash
python3 train.py --dataset cora
```

Run with the following for multilabel classification with PPI dataset
```bash
python3 train_ppi.py
```

> **_NOTE:_**  Users may occasionally run into low accuracy issue (e.g., test accuracy < 0.8) due to overfitting. This can be resolved by adding Early Stopping or reducing maximum number of training epochs.

Summary
-------
* cora: ~0.821
* citeseer: ~0.710
* pubmed: ~0.780
* ppi: ~0.9744
