Stanford Pos Tagger中的错误 [英] Error in Stanford Pos Tagger

问题描述

您好，我正在尝试使用Stanford Pos Tagger对某个句子进行POS标签.我在Windows7上使用Python 3.4 nltk 3.1 以下是我使用的代码:

Hello i am trying to do POS tag for a certain sentence using Stanford Pos Tagger. I am using Python 3.4 nltk 3.1 on windows7 Following is the code i used:

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))

但是，我遇到以下错误:
