导入 scipy.stats 时 "from new import instancemethod" 后出错

Question

每当我尝试导入 nltk 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 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）中执行了这个命令。我没有发现任何关于此错误的信息，而且缩进看起来没有错。

语法错误在你的文件new.py中（我猜它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），然后内部 scipy 导入应该可以正常工作。

另一方面，您可以升级到 scipy0.19.x。他们在那里删除了导入，它应该可以正常工作。

请注意，将 python 个文件命名为 builtin-modules 总是一个坏主意！这是异常或意外行为的常见来源。
