java - 初期化時に ND4J ライブラリのロードに失敗する: Unsatisfied Link Error

Question

deep4j でプログラムを作成していますが、プログラムを初期化しようとするとライブラリの問題が発生します。以下のJavaコードでライブラリパスを手動で設定したように見えるという事実以外に、ライブラリをロードできないと言っています。

Failed to load for libnd4jcpu: java.lang.UnsatisfiedLinkError: no libnd4jcpu in java.library.path

ライブラリのロード パスを手動で設定しようとしましたが、まだ機能しません。

    String libPathProperty = System.getProperty("java.library.path");
    System.setProperty("java.library.path", libPathProperty + ":/users/<user>/.javacpp/cache");
    System.out.println(System.getProperty("java.library.path"));
    System.setProperty("org.bytedeco.javacpp.logger.debug","true");

私の Pom は、https://nd4j.org/getstartedの手順に従っていると思います。以下に掲載しています。

libnd4jcpu が存在することがわかるので、何が問題なのかわかりません。
