To proceed with Neo4J network analytics, I need the database to have two libraries apoc and gds

Please install the libraries in the database in order for us to be able to compute network analytics.

For more information of installation of the libraries:

  1. apoc: https://neo4j.com/labs/apoc/4.1/installation/
  2. gds: https://neo4j.com/docs/graph-data-science/current/installation/

Also you could easilly test the installation using
RETURN gds.version(); and RETURN apoc.version();

It seems there's an issue with the gds library installation

    raise Neo4jError.hydrate(**metadata)
neo4j.exceptions.ClientError: {code: Neo.ClientError.Procedure.ProcedureCallFailed} {message: Failed to invoke procedure `gds.localClusteringCoefficient.stream`: Caused by: java.io.FileNotFoundException: JAR entry META-INF/services/org.neo4j.gds.triangle.intersect.RelationshipIntersectFactory not found in /plugins/neo4j-graph-data-science-2.3.1.jar}

Is the graph data science jar file added properly to the server?

There was a need to update the gds library and is done by Moin. The issue is resolved.
