斯坦福Posger Tagger中的錯誤

Question

您好，我正在嘗試使用Stanford Pos Tagger爲某個句子做POS標籤。我使用Python 3.4 NLTK 3.1 windows7的 以下是我使用的代碼：

import nltk 
from nltk.tag.stanford import POSTagger 
import os 
java_path = r"C:\Program Files\Java\jre1.8.0_66\bin\java.exe" 
os.environ['JAVAHOME'] = java_path 

St=POSTagger(r"C:\Python34\Scripts\stanford-postagger-2015-12-09\models\english-bidirectional-distsim.tagger",r"C:\Python34\Scripts\stanford-postagger-2015-12-09\stanford-postagger.jar") 

tokens = nltk.tokenize.word_tokenize("Sample for tagging a sentence.") 
print(St.tag(tokens)) 

然而，我收到以下錯誤：

Traceback (most recent call last): 
Loading default properties from tagger C:\Python34\Scripts\stanford-postagger-2015-12-09\models\english-bidirectional-distsim.tagger

File "C:\Python34\lib\site-packages\nltk\internals.py", line 160, in java  raise OSError('Java command failed!') 
OSError: Java command failed! 

請誰能幫我解決這個錯誤？

嘗試添加兩個更多的jar文件兩個你的構建路徑。您將在下載的軟件包slf4j-api.jar和slf4j-simple.jar的lib文件夾中找到這些文件。 看一看到this tutorial
