CUDA out of memory when the graph(edge_index and x) is big #247

Open

My graph: tens of millions edges and 70000 nodes
My model is something like GCNConv+GRU(GRU's reset, update and the other part is GCNConv)

Problem: cuda memory usage becomes bigger and bigger as time steps add.

How can I revise GNN part or RNNs part to solve this?
