java - 在 python 3.4 中使用 java 和 nltk

Question

我想在我的项目中使用 stanford-tagger，但出现以下错误。

  File "C:\Python34\lib\site-packages\nltk\tag\stanford.py", line 59, in tag
    return self.tag_sents([tokens])[0]
  File "C:\Python34\lib\site-packages\hazm\POSTagger.py", line 25, in tag_sents
    return super(stanford.POSTagger, self).tag_sents(refined)
  File "C:\Python34\lib\site-packages\nltk\tag\stanford.py", line 64, in tag_sents
    config_java(options=self.java_options, verbose=False)
  File "C:\Python34\lib\site-packages\nltk\internals.py", line 82, in config_java
    _java_bin = find_binary('java', bin, env_vars=['JAVAHOME', 'JAVA_HOME'], verbose=verbose, binary_names=['java.exe'])
  File "C:\Python34\lib\site-packages\nltk\internals.py", line 544, in find_binary
    binary_names, url, verbose))
  File "C:\Python34\lib\site-packages\nltk\internals.py", line 538, in find_binary_iter
    url, verbose):
  File "C:\Python34\lib\site-packages\nltk\internals.py", line 517, in find_file_iter
    raise LookupError('\n\n%s\n%s\n%s' % (div, msg, div))
LookupError: 

===========================================================================
NLTK was unable to find the java file!
Use software specific configuration paramaters or set the JAVAHOME environment variable.
===========================================================================

NLTK 无法找到 java 文件!使用软件特定的配置参数或设置 JAVAHOME 环境变量。

请帮我设置java变量。我使用 Windows 8 64 位和 python 3.4

将其添加到您的代码中:

java_path = "C:/Program Files/Java/jdk1.8.0_191/bin/java.exe"
os.environ['JAVAHOME'] = java_path
