create_link_graph

This method create_link_graph creates MRXLinkDagModel class, which creates a DAG graph through components and edges information.

Create Link graph

create_link_graph(
    components: Optional[List[MRXLinkComponentModel]] = None,
    edges: Optional[List[MRXLinkDagEdgeModel]] = None,
) -> MRXLinkDagModel

• Parameters

  • components(list): List of components created using the create_link_component method (create_link_component)
  • edges(list): List of edges created using the create_link_edge method (create_link_edge)

• Returns

  • MRXLinkDagModel(nodes=components, edges=edges)

• Troubleshooting

  • RuntimeError: This component name already exists in the pipeline.
    • This occurs when a duplicate component ID is entered.
  • ValueError: Component name is duplicated
    • This occurs when a duplicate component name is entered.
  • There is no component corresponding to parent_id '{parent_id}'
    • This occurs when the parent component ID that is entered does not exist.
  • There is no component corresponding to child_id '{child_id}'
    • This occurs when the child component ID that is entered does not exist.
