  • model (EmbeddingModel) – A trained neural knowledge graph embedding model, the model must be an instance of TransE, DistMult, ComplEx, or HolE.
  • model_name_path (string) – The name of the model to be saved. If not specified, a default name model with current datetime is named and saved to the working directory
