How to extract text of retrieved_nodes

[kezhen1]

Hello, I am trying to reproduce CoCoMIC, but finds that entity in retrieved_nodes is just locale like "src.diffusers.models.vq_model.VQModel.init" but doesn't include contents of implementation of that entity.
Could you please show how to find the content of each entity in retrieved_nodes?

{
"prompt": " ... ",
"groundtruth": " ... ",
"retrieved_nodes": [
" ...<PROJECT_ENTITY>... ",
],
"retrieved_edges": [
["<ENTITY_IDX>", "<RELATION_TYPE>", "<RELATION__TYPE_IDX>", "<ENTITY_IDX>"],
],
"metadata": {
"file":"<ABSOLUTE_FILE_PATH>"
}
}
