How to explain the GNN network of MessagePassing class

[688spiderbin]

Hello!
Could you update the tutorial of Captum for network of MessagePassing class in the doc. I have tried searching some discussions about how to explain the messagepassing class. But it's quite messy and it's hard to follow.

I appreciate a lot !

Can you clarify what you want to have updated exactly, and where you are stuck?

How is your CaptumExplainer defined?

I remember I upload that screen shot before, please check :

Note that you need to pass in additional arguments as keyword arguments in the explainer:

explainer(data.x, data.edge_index, edge_attr=data.edge_attr, batch=data.batch)

I am not sure if this resolved your issue.

Yep, you have suggested to me this before, it's cannot work.

Sorry for late reply. This works fine on our end, see here. I am not yet sure what is the problem though.
