5 months ago Hi @icejean.
This problem is a bit surprising, but I think it stems from an outdated source tree. When you say that you 'download the source of GDS 2.5.7', what does that mean precisely?
Normally, one would clone this repository to get the source code, using something like
git clone git@github.com:neo4j/graph-data-science.gitThen you can use git functionality to browse around in the repo's commit history. There is a tag 2.5.7 that denotes the state of the repository at the release of GDS 2.5.7, where compatibility for Neo4j DBMS 5.16.0 is included. But this denotes the official release of Neo4j GDS, which is subtly different from OpenGDS. OpenGDS is not a product that we release, but it is an open source project that people like yourself can fork, extend, contribute to, build and use, all under the remits of the GPLv3 license.
So the version number 2.5.7 does not actually refer to a version of OpenGDS. In fact, OpenGDS will receive compatibility for Neo4j DBMS versions with a slight delay from the official release of GDS the product. In this case, we added 5.16 compatibility on Jan 11 and published it to OpenGDS on Jan 22.
So how to resolve your problem? I think the easiest way to do that is to make sure you are at the very head of the 2.5 branch when you build OpenGDS with the Gradle command (which looks correct, by the way). If you are using git as I described above, you can do for example this:
git checkout 2.5or maybe like this:
git checkout -b my-2.5-branch;
git reset --hard origin/2.5;(The last command assumes that you have named the upstream repo (this repo) origin, which is conventional. If you named it otherwise, just change origin to that name.)
At the very least, you should be at commit 7ecd04b5f9.
Note also that the version you will get when you build from the very head of the 2.5 branch is not 2.5.7 but 2.5.8 (unless you override the build configuration). That probably doesn't matter so much.
You can also build OpenGDS from the head of the master branch. In that case it will be versioned 2.7.0 but it will work with Neo4j DBMS 5.16 as well.
I hope this helps!

Hi, all, I download the source of GDS 2.5.7 and build Open GDS package with the following command:
According to GDS's document Neo4j Community 5.16.0 should work with Open GDS 2.5.7, but Neo4j Community 5.16.0 failed to start and get the following exceptions saying that GDS 2.5.7 is not compatible with Neo4j version: 5.16, any idea?
