I am trying to use node2vec in Neo4j Desktop. My DB is v. 4.4.4. I have installed Graph Data Science Library (1.8.5) from the plugins tab. But when I try to use "CALL gds.beta.node2vec.stream" I get

There is no procedure with the name gds.beta.node2vec.stream registered for this database instance. Please ensure you've spelled the procedure name correctly and that the procedure is properly deployed.

Any ideas?

  • Are you sure that you have restarted the instance after the GDS installation. (Of course) this happened to me also and I was 100% sure that I have restarted ;) Tried it at my machine with 4.4.4 and 1.8.5 and it worked. – meistermeier Mar 17 '22 at 12:18
  • It seems that when I upgraded neo4j db to 4.4.4, Graph Data Science plug-in was disabled. Thank you @meistermeier for your comment it helped me notice this. – Dimitrios Panagopoulos Mar 17 '22 at 12:37

Ensure that you add below configs in $NEO4J_HOME/conf/neo4j.conf where $NEO4J_HOME is your home directory where neo4j server is installed.

    dbms.security.procedures.unrestricted=gds.*
    dbms.security.procedures.allowlist=gds.*

Then RESTART the neo4j server using below:

    $NEO4J_HOME/bin/neo4j restart
