Heterogeneous graph pooling

Questions
#1

Whether there are cases related to heterogeneous graph pooling in dgl？

#2

please refer to dgl.nn (PyTorch) — DGL 2.1.0 documentation for pooling layers. And for heterographs, you could refer to readout APIs with types.

And could you elaborate more about your use case?

#3

Thank you very much for your answer, because I saw that dgl has a pooling implementation of the same graph, and I was wondering if there are any cases of heterogeneous graph. I was recently learning a task on heterogeneous diagram classification, and I was wondering if I could apply heterogeneous diagram pooling to my task.
