org.nd4j.linalg.factory.Nd4j.zeros(long, long)

Trying to use io.github.ensozos.core.MPdistance.getMPdistance using Maven, I get the following error:

Exception in thread "main" java.lang.NoSuchMethodError:
 'org.nd4j.linalg.api.ndarray.INDArray org.nd4j.linalg.factory.Nd4j.zeros(long, long)'
    at io.github.ensozos.core.MPdistance.getMassDistMatrix(MPdistance.java:116)
    at io.github.ensozos.core.MPdistance.getMPdistance(MPdistance.java:52)
    at Main.Main.main(Main.java:104)

I am using Nd4j version 1.0.0-beta7.

I believe that this is an error related to org.nd4j.linalg.api.ndarray.INDArray not having a zeros(long, long) method. Is there a way to solve the problem?

Solution

  • I ran mvn dependency:tree on your project and it turns out there were older versions being pulled in:

    (See beta2 vs beta7) I would suggest just taking the source code of this library and updating it. A fork is needed unless the author of the library intends to update the version.

    Updating the version that's included with your project won't work because some changes from beta2 to 7 were done that broke the backwards compatibility here.
