使用python在opencv中加载DLL失败

Question

I wish if anyone could give me a hand with my prob, I have installed python 3.6 amd64 and add it to path then installed opencv 3.2 successfully using "pip" ... However, when I'm trying to import the cv2 (the library of opencv) and here is the error that I have got:

Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    import cv2
ImportError: DLL load failed: The module specified is not found.

Answer 1

I'm guessing you've installed pip2(for python2) instead of pip3.(for python3) Try this to install pip for python3

sudo apt-get install python3-pip 

Now use

pip3 install python3-opencv

Answer 2

Make sure that cv2.pyd is in your Python's lib\\site-packages\\ directory.

Also check if OPENCV_DIR = C:\\Program Files\\OpenCV 3.2.0\\x64\\vc14 , or similar, is in your Windows' system variables setting. The sample path OPENCV_DIR is for the binary compiled with VC14 which is Visual Studio 2015 VC++ .
