Couldnt use Cosine similarity Algorithm in my Neo4j Desktop

[kumarss20]

Getting unknown function 'algo.similarity.cosine' while trying to use RETURN algo.similarity.cosine([3,8,7,5,2,9], [10,8,6,6,4,5]) AS similarity in community edition Neo4J Desktop

Reference:https://neo4j.com/docs/graph-algorithms/current/algorithms/similarity-cosine/

I have installed graph algorithm install for the whole project .

I have this dbms.security.procedures.unrestricted=apoc.,algo. enabled in my config.

When i execute CALL algo.list() , i'm not seeing 'algo.similarity.cosine' procedure/function listed .but could see lot of other algo.* functions and procs

Am i missing anything ? Help is much appreciated .

You may be using an older version of the algo library.

Cosine and other similarity functions and procedures were only added with the latest 3.4.7.0 release. I believe this is only compatible with the 3.4.x versions of Neo4j.

You may need to stop your db, uninstall the plugin, and install again (you should see the version change upon uninstalling the older version).

It works when i use 3.4.7 exactly ... earlier it didnt work for latest version (3.4.8) ...

Thanks for you help Andrew.

3.4.8 was just released, Desktop needs to be modified to allow installation of the libraries. Also, if any code changes are needed to work with the latest version that may require an additional release to the algo library, but that's not always the case.
