Question

我正在尝试根据此链接中的建议安装Tensorflow for java ...

https://www.tensorflow.org/install/install_java#install_on_windows

说明指出要下载.jar文件，以及.dll的单独文件。我已将jar文件包含到netbeans项目中，并设置上面网页上列出的代码。

package tensorflowtest;
import org.tensorflow.Graph;
import org.tensorflow.Session;
import org.tensorflow.Tensor;
import org.tensorflow.TensorFlow;


public class TensorFlowTest {

    public static void main(String[] args) throws Exception {
    try (Graph g = new Graph()) {
      final String value = "Hello from " + TensorFlow.version();

      // Construct the computation graph with a single operation, a constant
      // named "MyConst" with a value "value".
      try (Tensor t = Tensor.create(value.getBytes("UTF-8"))) {
        // The Java API doesn't yet include convenience functions for adding operations.
        g.opBuilder("Const", "MyConst").setAttr("dtype", t.dataType()).setAttr("value", t).build();
      }

      // Execute the "MyConst" operation in a Session.
      try (Session s = new Session(g);
           Tensor output = s.runner().fetch("MyConst").run().get(0)) {
        System.out.println(new String(output.bytesValue(), "UTF-8"));
      }
    }
  }

}

运行此时，我收到错误

Exception in thread "main" java.lang.UnsatisfiedLinkError: Cannot find TensorFlow native library for OS: windows, architecture: x86. See https://github.com/tensorflow/tensorflow/tree/master/java/README.md for possible solutions (such as building the library from source).
    at org.tensorflow.NativeLibrary.load(NativeLibrary.java:66)
    at org.tensorflow.TensorFlow.init(TensorFlow.java:27)
    at org.tensorflow.TensorFlow.<clinit>(TensorFlow.java:31)
    at org.tensorflow.Graph.<clinit>(Graph.java:194)
    at tensorflowtest.TensorFlowTest.main(TensorFlowTest.java:11)

我知道这是因为找不到.dll文件，但我尝试将.dll放在所有根文件中，我尝试将dll添加到我的源和/或库中，我尝试添加命令-Djava.library.path =。到我在Netbeans中的VM选项，并尝试添加System.setProperty（“java.library.path”，“。”）;到我的主要功能的开头，都没有成功。我也尝试以“C：\ Path \ To \ File”

的形式提供到dll的直接路径

如何解决这个问题的任何建议将不胜感激。

Answer 1

如果该文件位于运行目录中，则它应该首先就可以正常工作（我遗漏了什么吗？）在“虚拟机选项”下设置正确的绝对路径对我有用：

-Djava.library.path="C:\Program Files\Java\tensorflow"

通过这种方式，您不必在项目之间来回复制dll。

另请参阅：giving 'java.library.path' in netbeans for .dll/.so files

Answer 2

看起来像将tensorflow_jni.dll文件放在项目文件夹的根目录中一样，如下所述：

将Tensorflow添加到Java Project Netbeans
