Hi, everybody. I am using OpenCV 3.4.3 after setting up the OpenCV library. The problem happens because the numpy.core.multiarray can not import when importing cv2:

(D:\\Users\\XXX\\Anaconda3) C:\\Users\\XXX>python
Python 3.6.3 |Anaconda, Inc.| (default, Oct 15 2017, 03:27:45) [MSC v.1900 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
RuntimeError: module compiled against API version 0xc but this version of numpy is 0xb
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
ImportError: numpy.core.multiarray failed to import

Please show me methods if anyone know to solve it. Thanks!!!

    The cause:

    The issue happens because your opencv3 version is not matching up with the numpy version. And, you need to bring up to date the new numpy version.

    Solution:

    Firstly, you need to go into the console window.

    pip install -U numpy

    Secondly, the downgrade is finished after being got the following message.

    (D:\Users\XXX\Anaconda3) C:\Users\XXX>pip install -U numpy
    Collecting numpy
                                                                       Downloading 
    https:files.pythonhosted.org/packages/51/70/7096a735b27359dbc0c380b23b9c9bd05f

      100% | ██████████ █████████████████████ | 13.5MB 27kB/s
    Installing collected packages: numpy
    Found existing installation: numpy 1.12.0
     Uninstalling numpy-1.12.0:
      Successfully uninstalled numpy-1.12.0
    Successfully installed numpy-1.15.4

    Finally, checking again, import cv2 has success.

    (D:\Users\XXX\Anaconda3) C:\Users\XXX>python
    Python 3.6.3 |Anaconda, Inc.| (default, Oct 15 2017, 03:27:45) [MSC v.1900 64 bit (AMD64)] on win32
    Type "help", "copyright", "credits" or "license" for more information.
    >>> import cv2
    >>>

    Hope with the above method you can with solve the issue you get. Good luck!!!
