python - 导入 scipy.stats 时出现 "from new import instancemethod"后错误

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>

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)中执行了这个命令。我没有发现任何有关此错误的信息，并且缩进看起来没有错误。

语法错误位于您的文件new.py中(我猜它位于您当前的工作目录中)。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 导入应该可以正常工作.

另一方面，您可以升级到 scipy 0.19.x。他们删除了那里的导入，它应该可以正常工作。

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