Question

每当我尝试导入scipy包时，我都会从nltk收到异常。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>

return copy.deepcopy(self)

IndentationError: expected an indented block

我在终端（ubuntu 16.04 LTS系统）中执行了此命令。我没有发现任何有关此错误的信息，并且缩进看起来不错。

SyntaxError位于您的文件new.py中（我猜它在您当前的工作目录中）。尝试切换到没有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.他们删除了那里的导入，它应该没有问题。

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