The same error occurs when executing any program:

The pom.xml file configuration is as follows:

deeplearning4j-core (1.0.0-beta7),
nd4j-native-platform (1.0.0-beta7),
slf4j-nop (2.0.0-alpha1)

Execute the java file as follows:

package Learning.ForTest;

import java.io.IOException;

import org.nd4j.linalg.api.ndarray.INDArray;
import org.nd4j.linalg.factory.Nd4j;

public class App {
public static void main(String[] args) throws IOException{
System.out.println(Nd4j.getBackend());
INDArray tensor1 = Nd4j.create(new double[]{1,2,3});
INDArray tensor2 = Nd4j.create(new double[]{10.0,20.0,30.0});
System.out.println(tensor1.add(tensor2));
}
}

Please indicate relevant versions, including, if relevant:

My computer system is windows. I tried to execute other java programs and encountered the same problem. Please help me see what is the reason, thank you very much.
