Installed neo4j and it is running fine. Downloaded the data science library and copied it over to plugins.

neo4j refuses to start, does not give error on the start or console command, says it has started, but the log file shows the following error:

Did anyone face the same problem or knows a work around for the data science library to work?

If I remove the library neo4j-graph-data-science-2.3.1.jar from plugins folder neo4j works fine again

  • Can you include the version of the GDS library you installed? There may be a version mismatch. – fbiville Apr 17 '23 at 07:49

    I have been able to resolve this issue. It was indeed the version 2.3.1 which probably packaged some dependency on Aura related classes. I have downloaded the 2.3.2 latest release from the following link https://github.com/neo4j/graph-data-science/releases/tag/2.3.2 now it works just fine – earthdomain Apr 17 '23 at 11:04
