Question

我正在尝试使用以下程序运行coreNLP包

package corenlp;
import edu.stanford.nlp.pipeline.*;
import java.io.IOException;
/**
 *
 * @author Karthi
 */
public class Main {

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) throws IOException, ClassNotFoundException {
        // TODO code application liogic here
        String str="-cp stanford-corenlp-2010-11-12.jar:stanford-corenlp-models-2010-11-06.jar:xom-1.2.6.jar:jgrapht-0.7.3.jar -Xms3g edu.stanford.nlp.pipeline.StanfordCoreNLP [ -props <Main> ] -file <input.txt>";
        args=str.split(" ");
        StanfordCoreNLP scn=new StanfordCoreNLP();
        scn.main(args);
    }

}

我不确定代码本身是否正确，但是我收到以下错误

我尝试在netbeans中的VM选项中提供这些值，但是对于每个值，我都会收到错误

-Xms3g

run:
Error occurred during initialization of VM
Incompatible initial and maximum heap sizes specified
Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)

-Xmx3g

run:
Error occurred during initialization of VM
Could not create the Java virtual machine.
Could not reserve enough space for object heap
Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)

-Xms3g -Xmx4g

run:
Could not create the Java virtual machine.
Invalid maximum heap size: -Xmx4g
The specified size exceeds the maximum representable size.
Java Result: 1
BUILD SUCCESSFUL (total time: 0 seconds)

Answer 1

你在运行这个操作系统？它是64位系统吗？如果没有，那么当涉及到可以为单个Java进程分配多少堆时，您几乎受到限制。尝试使用-Xms1024M -Xmx1024M投放并查看它是否解决了您的问题。

Answer 2

尝试使用运行时参数

java -cp -XX:+AggressiveHeap -jar jarfile

或

java -cp... -XX:MaxHeapFreeRatio=70 -XX:+UseLargePages -jar jarfile

超出堆空间内存错误
