Good question. I think we can not get it directly currently. But the mechanism should have support it. For example, when you pass the output index, we could use nodes_[outputs_[index].node_id].name to get the name.
Something a bit more, I think the name you want more is the model’s name, then you need the pr https://github.com/apache/incubator-tvm/pull/6885 for frontend keeping model node’s name and pass this name to TVM node correctly. Then previous code could get the correct output name for you.
