PYG to ONNX

[CY-SCUT]

Can you please tell me what cannot be used after converting PYG to Onnx now? Or are there any existing issues total?

I don't have a full coverage report, but we test our standard GNN layers with it (e.g, GCN, GraphSAGE, GAT, ...) and they seem to be converting just fine to ONNX.
