错误蟒蛇

Question

从tethne进口槌在我的Python项目中，我一直在说：

from tethne.model.corpus import mallet 

，但我的问题是，当我跑我的项目，我在pycharm控制台中看到这些错误：

Traceback (most recent call last): 
    File "D:/Python-Workspace(s)/BehnazDemo/Demo.py", line 1, in <module> 
    from tethne.model.corpus import mallet 
    File "C:\Users\Administrator\AppData\Local\Programs\Python\Python35-32\lib\site-packages\tethne-0.8-py3.5.egg\tethne\__init__.py", line 20, in <module> 
    from tethne.classes.paper import Paper 
    File "C:\Users\Administrator\AppData\Local\Programs\Python\Python35-32\lib\site-packages\tethne-0.8-py3.5.egg\tethne\classes\paper.py", line 5, in <module> 
    from tethne.classes.feature import Feature, feature 
    File "C:\Users\Administrator\AppData\Local\Programs\Python\Python35-32\lib\site-packages\tethne-0.8-py3.5.egg\tethne\classes\feature.py", line 20, in <module> 
    from itertools import chain, izip 
ImportError: cannot import name 'izip' 

我该如何解决这个问题？

谢谢。

Answer 1

看来你使用Python3.x，所以代码应该是：

try: 
    from itertools import izip as zip 
except ImportError: # Python3.x you can just use zip 
    pass 

或者：

from itertools import zip_longest 

Python 3里不再有itertoolsizip，但内置zip与Python2.x中的izip的功能相同。
