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：斯坦福Posger Tagger中的錯誤
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):
