windows, ImportError: DLL load failed: The specified module could not be found
提问by Jahid Rahman
import numpy as np
import cv2
from matplotlib import pyplot as plt
img = cv2.imread('12.jpg',0)
orb = cv2.ORB()
kp = orb.detect(img,None)
kp, des = orb.compute(img, kp)
img2 = cv2.drawKeypoints(img,kp,color=(0,255,0), flags=0)
plt.imshow(img2),plt.show()
I have added the numpyand cv2modules to my python directory and set their environment variables.
我已将numpy和cv2模块添加到我的 python 目录并设置它们的环境变量。
I also installed msvcp71.dlland msvcr71.dll, but this error has not solved.
我也安装了msvcp71.dlland msvcr71.dll，但是这个错误没有解决。
So how can i fix this kind of dll problem?

I suspect you've mixed a x64pythonwith x86cv2.pydfile, or vice versa. Simple way is to install a right version of opencv here: http://www.lfd.uci.edu/~gohlke/pythonlibs/#opencv
我怀疑您将x64python与x86cv2.pyd文件混合在一起，反之亦然。简单的方法是在此处安装正确版本的 opencv：http: //www.lfd.uci.edu/~gohlke/pythonlibs/#opencv

To check your pythonarch:
检查您的python足弓：
In [2]: import platform
In [3]: platform.architecture()
Out[3]: ('64bit', 'WindowsPE')
and cv2.pyd:
I suggest using PESnoop:
和cv2.pyd：我建议使用PESnoop：
D:\Anaconda\Lib\site-packages> PESnoop cv2.pyd /pe_dh
