Question

我遇到了一个有趣的错误，我可以在终端上的Ipython中import cv2，但无法在Jupyter笔记本上导入库。我检查了内核，但我使用相同的内核（Anaconda python2.7）

有人知道如何解决这个问题吗？

Answer 1

在opencv.pth下创建一行/Users/kn/anaconda2/lib/python2.7/site-packages文件。

该文件的内容如下：

/usr/local/opt/opencv3/lib/python2.7/site-packages

这将永久地在所有conda环境下附加opencv3路径。我认为这比为python2环境提供cv2更好。

在Jupyter Notebook上导入错误OpenCV（但它在终端上的Ipython中工作..）
