IndexError: Encountered an index error.

Hello everyone

I have an error in the heterogeneous GNN model with this type:
IndexError: Encountered an index error. Please ensure that all indices in 'edge_index' point to valid indices in the interval [0, 161] (got interval [94384626, 3232300794])

I don't know where is this interval [94384626, 3232300794] from?
can you help me?

data.validate()

ValueError: 'edge_index' of edge type ('src', 'to', 'dst') contains larger source indices than the number of nodes (162) of this node type in 'HeteroData' (found 3232300794)

Thanks for sharing the output of data.validate. It looks like you have invalid edges in your edge_index , clean up the edge_index before passing the graph to the GNN.
