Question

我在CentOS机器上安装了nltk 3.2.1 现在，每当我尝试下载NLTK的任何语料库/模型时，它都会给出以下错误：

Traceback (most recent call last):
File "/usr/lib64/python2.7/runpy.py", line 162, in _run_module_as_main

File "/usr/lib64/python2.7/xml/etree/ElementTree.py", line 1506, in _raiseerror
raise err
xml.etree.ElementTree.ParseError: syntax error: line 1, column 49

请注意，我已尝试以下所有方法下载NLTK数据 -

nltk.download()
nltk.download('all')
python -m nltk.downloader all

但在所有方法中我都收到同样的错误任何人都知道我为什么会收到此错误以及如何下载NLTK数据？任何帮助，将不胜感激！

让我们看看：您的下载程序会打开列出可用下载的xml文档，尝试解析它并收到错误：

ElementTree.parse(compat.urlopen(self._url)).getroot())

要么（非常不可能）nltk网站不再与Python 2.7兼容，或者您实际上没有收到预期的XML文档，因为您的连接有问题。你是behind a proxy?如果没有，你的连接可能还有其他问题。
