8.4.1 Loading a Graph

The following describes the steps for loading a graph:

1. Create a Session and an Analyst.
   • JShell
   • Java
   • Python

   cd /opt/oracle/graph/
   ./bin/opg4j
   // starting the shell will create an implicit session and analyst

   import oracle.pgx.api.*;
   import oracle.pgx.api.mllib.Pg2vecModel;
   import oracle.pgx.api.frames.*;
   ...
   PgxSession session = Pgx.createSession("my-session");
   Analyst analyst = session.createAnalyst();

   session = pypgx.get_session(session_name="my-session")
   analyst = session.create_analyst()

2. Load the graph.
   • JShell
   • Java
   • Python

   opg4j> var graph = session.readGraphWithProperties("<path>/<graph.json>")

   PgxGraph graph = session.readGraphWithProperties("<path>/<graph.json>");

   graph = session.read_graph_with_properties("<path>/<graph.json>")
