WebJun 20, 2024 · You can pass the dict to hetero model. Line h_dict = model (hetero_graph,confeature) should change to h_dict = model (hetero_graph, node_features) And the output of GATConv is [batch_size, hidden_dim, num_heads], you need to flat the later two dimension to pass it to the next GraphConv modules. Below is the code I fixed …

WebJul 3, 2024 · 1. I am trying to train a simple graph neural network (and tried both torch_geometric and dgl libraries) in a regression problem with 1 node feature and 1 node level target. My issue is that the optimizer trains the model such that it gives the same values for all nodes in the graph. The problem is simple. In a 5 node graph, each node … WebTry to write a 2-layer GAT model that makes use of 8 attention heads in the first layer and 1 attention head in the second layer, uses a dropout ratio of 0.6 inside and outside each GATConv call, and uses a hidden_channels dimensions of 8 per head.
