python中的句子拆分代码问题

Question

这是我在 python 中的分句代码

 import nltk.data
 tokenizer = nltk.data.load('tokenizers/punkt/english.pickle')
 fp = open("newoutput.en")
 data1 = fp.read()
 print '\n-----\n'.join(tokenizer.tokenize(data1))

但在执行时，我收到以下错误：

Traceback (most recent call last):
  File "pythontokeniser.py", line 7, in <module>
    print '\n-----\n'.join(tokenizer.tokenize(data1))
  File "/usr/local/lib/python2.7/dist-packages/nltk/tokenize/punkt.py", line 1237, in tokenize

Answer 1

以字节模式打开文件如下：

fp = open("newoutput.en", 'rb')

或尝试使用“ISO-8859-1”进行编码。
