导入scipy.stats时出现“from new import instancemethod”后出错

Question

每当我尝试导入nltk软件包时，我都会收到来自scipy的异常。命令和错误如下所示：

>>> import nltk 
Traceback (most recent call last): 
File "<stdin>", line 1, in <module> 
File "/usr/local/lib/python2.7/dist-packages/nltk/__init__.py", line 114, in <module> 
from nltk.collocations import * 
File "/usr/local/lib/python2.7/dist-packages/nltk/collocations.py", line  39, in <module> 
from nltk.metrics import ContingencyMeasures, BigramAssocMeasures, TrigramAssocMeasures

File "/usr/local/lib/python2.7/dist-packages/scipy/stats/_distn_infrastructure.py", line 43, in <module> 
from new import instancemethod 
File "new.py", line 107 
return copy.deepcopy(self) 
^ 
IndentationError: expected an indented block 

我在终端（ubuntu 16.04 LTS系统）中执行此命令。我没有发现有关此错误的任何信息，并且缩进看起来不错。

Answer 1

SyntaxError在你的文件new.py（我想这是在你当前的工作目录中）。尝试切换到不存在new.py文件的目录（或将new.py文件移动到另一个目录中），然后内部scipy导入应该没有问题。

另一方面，你可以升级到scipy 0.19.x.他们取消了进口，它应该没有问题。

请注意，命名Python文件如builtin-modules总是一个坏主意！这是异常情况或意外行为的常见来源。
