我正在嘗試執行我已爲我的自定義名稱進行培訓的OpenNLP模型。我執行下面的命令進行定製的模型：在OpenNLP中使用自定義NER模型時如何處理'ExtensionNotLoadedException'？
opennlp TokenNameFinderTrainer -encoding UTF-8琅恩-data C：\用戶\ nshah \桌面\ EN-NER-person.train -model EN-ner- personName.bin
我能夠成功地創建一個名爲EN-NER-personName.bin模型。
我現在想執行如下我的程序：
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.IOException;
import opennlp.tools.namefind.NameFinderME;
import opennlp.tools.namefind.TokenNameFinderModel;
import opennlp.tools.util.InvalidFormatException;
import opennlp.tools.util.Span;
public class NameFinder {
public String nameFind(String inputText){
String finalNames = "";
try {
TokenNameFinderModel tokenNameFinderModel = new TokenNameFinderModel(new FileInputStream("D://NISUM_OFFICIAL_WORKSPACE//opennlp//src//models//en-ner-personName.bin"));
NameFinderME nameFinderME = new NameFinderME(tokenNameFinderModel);
Tokenization tokenize = new Tokenization();
String[] tokens = tokenize.tokenization(inputText);
Span drugSp[] = nameFinderME.find(tokens);
String [] sp = Span.spansToStrings(drugSp, tokens);
StringBuilder string = new StringBuilder();
if(sp.length!=0){
for(int i=0;i<=sp.length;i++){
string = string.append(sp[i]+"\n");
}
finalNames = string.toString();
}
} catch (InvalidFormatException e) {
e.printStackTrace();
} catch (FileNotFoundException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}
return finalNames;
}
}
但上述程序執行後，我收到的控制檯下面例外提到：

請有人可以幫助我在這個問題上，我嘗試了很多事情並閱讀博客，但找不到有用的東西。如果有人能提供有用的解決方案，那將會非常感激。
