CV2问题：numpy.core.multiarray导入失败

Question

尝试使用以下方法解决它：

pip install -U numpy

但它仍然不起作用。

这是我尝试运行该应用程序时控制台向我显示的内容：

    RuntimeError: module compiled against API version 0xa but this version of numpy is 0x9
Traceback (most recent call last):
  File "/Users/Rubio/Desktop/logistic-regression/train.py", line 8, in <module>
    import cv2
  File "/Library/Python/2.7/site-packages/cv2/__init__.py", line 3, in <module>
    from .cv2 import *
ImportError: numpy.core.multiarray failed to import

Answer 1

重新安装 OpenCV：

conda install -c anaconda opencv (for anaconda users)
