希伯来语的空格句子标记化错误

正在尝试对希伯来语使用拼写句子标记化。

import spacy
nlp = spacy.load('he')
doc = nlp(text)
sents = list(doc.sents)

我得到：

    Warning: no model found for 'he'

    Only loading the 'he' tokenizer.

Traceback (most recent call last):   
  ...
    sents = list(doc.sents)   
  File "spacy/tokens/doc.pyx", line 438, in __get__ (spacy/tokens/doc.cpp:9707)
    raise ValueError( ValueError: Sentence boundary detection requires the dependency parse, which requires data to be installed. For more info, see the documentation:  https://spacy.io/docs/usage

怎么办？
