함수 이름 끝에 "r"이 누락 되었습니까? ""sent_tokenize ("Super Qualität. Tolles Teil.")에서 보냄 : –

@ Mr.Polywhirl 질문에 오타가 단지 :-). 이것은 문제가 아니 었습니다. – Chris

문제는 비 ASCII 문자가 포함 된 마지막 단어가있는 문장에 있습니다. 그러나 나는 그 이유를 모른다. 당신이 이런 식으로 "슈퍼 Qualität. Tolles Teil"을 사용한다면. 공장. –

나는,728에 해결책을 발견.

Caution: when tokenizing a Unicode string, make sure you are not using an encoded version of the string (it may be necessary to decode it first, e.g. with s.decode("utf8").

그래서 마법처럼

text = "Super Qualität. Tolles Teil." 
sent_tokenizer = nltk.data.load('tokenizers/punkt/german.pickle') 
for sent in sent_tokenizer.tokenize(text.decode('utf8')): 
     print sent

작품.
