我想使用Selenium的Firefox驱动程序.但是我得到了如下所示的错误.Firefox有可能无法正常安装吗？

------我的来源------

from selenium import webdriver

driver = webdriver.Firefox()

------我的源头------

这是返回的错误:

Traceback (most recent call last):
  File "test.py", line 4, in <module>
    browser = webdriver.Firefox()
  File "/usr/local/lib/python2.7/site-packages/selenium-2.25.0-py2.7.egg/selenium/webdriver/firefox/webdriver.py", line 51, in __init__
    self.binary, timeout),
  File "/usr/local/lib/python2.7/site-packages/selenium-2.25.0-py2.7.egg/selenium/webdriver/firefox/extension_connection.py", line 47, in __init__

我想从 NLTK 对非空白字符串获取形态分析结果。

例如：

字符串是"societynamebank".

我想要得到['society', 'name', 'bank']

如何在 NLTK 上获得该结果？
