I don't understand from where these numbers are being created. My edge_index values range only from 0-9. when a value of 10 is seen in the edge_index it means it's an unwanted edge and it will be eliminated later during the feature extraction.
WebJul 11, 2024 · So far, we discussed how we can calculate latent features of a graph data structure. But if we want to accomplish a particular task we can guide this calculation toward our goal. ... x = data.x.float() edge_index = data.edge_index x = self.conv1(x=x, edge_index=edge_index) x = F.relu(x) x = self.conv2(x, edge_index) return x. WebNode or edge tensors will be automatically created upon first access and indexed by string keys. Node types are identified by a single string while edge types are identified by using a triplet (source_node_type, edge_type, destination_node_type) of strings: the edge type identifier and the two node types between which the edge type can exist. As such, the …
