Conda / Python：导入错误 – 仅在jupyter笔记本中找不到图像

2023年5月4日 336次阅读

我在一台jupyter笔记本中输入了scipy.io失败.令人困惑的部分是我在i
Python终端中没有得到相同或任何错误,但我在标准的Python终端中.这让我想到,不知怎的,我的jupyter会话使用的是不同于其他会话的链接路径,但是我还没有弄清楚如何接近/调试/修复它.

我的问题：

>有没有其他人遇到这个或类似的东西？
> jupyter不应该在终端和笔记本会话中使用相同的库路径吗？
>我在下面的conda信息中包含了我的路径设置.任何人都会有关于如何/为何发生这种情况的事情吗？

最后一点,这是来自conda信息的转储：

最佳答案 这似乎是conda构建的一个错误：

https://github.com/ContinuumIO/anaconda-issues/issues/899

一位评论员(@stuarteberg)就此问题表示：

The new latest scipy version (0.18.0) also has the same problem. In case it’s somehow useful, the conda-forge package for scipy is not broken in this way.

@andykitchen发现将scipy降级到0.17.0修复了问题：

Yup can confirm I had this problem as well, the fix for me was to also to downgrade to 0.17.0

conda install --force scipy=0.17.0
