我scipy.io在jupyter笔记本中导入失败。令人困惑的是，我在iPython终端中没有出现相同或任何错误，但在标准Python终端中。这使我认为以某种方式，我的jupyter会话使用的链接路径不同于其他会话，但是我一直无法弄清楚如何处理/调试/修复该链接。
我的问题：
conda info下面包括了我的路径设置。关于这是如何/为什么发生的事，有什么要对任何人说的吗？在IPython终端中

这似乎是conda版本的错误：
https://github.com/ContinuumIO/anaconda-issues/issues/899
一位对此问题的评论者（@stuarteberg）说：
新的最新scipy版本（0.18.0）也存在相同的问题。在某种程度上有用的情况下，scipy的conda-forge软件包不会以此方式损坏。
@andykitchen发现将scipy降级为0.17.0可以解决此问题：
是的，我也可以确认我也有这个问题，对我来说，解决方法是也降级到0.17.0
conda install --force scipy=0.17.0
