python - 窗口，导入错误 : DLL load failed: The specified module could not be found

Question

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()

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。

我还安装了msvcp71.dll和msvcr71.dll，但是这个错误并没有解决。

那么我该如何解决这种dll问题呢？

版本信息:

1. Python 3.2

2. numpy-1.6.1-win32-superpack-python3.2

3. opencv-3.0.0

我怀疑您将 x64 python 与 x86 cv2.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

在这里查看讨论:

1. ImportError: DLL load failed: %1 is not a valid Win32 application. But the DLL's are there

检查您的 python 架构:

In [2]: import platform

In [3]: platform.architecture()
Out[3]: ('64bit', 'WindowsPE')

和cv2.pyd:我建议使用 PESnoop :

D:\Anaconda\Lib\site-packages> PESnoop cv2.pyd /pe_dh
-------------------------------------------------------------------------------
 PESnoop 2.0 - Advanced PE32/PE32+/COFF OBJ,LIB command line dumper by yoda

Dump of file: cv2.pyd...
Modus:        64bit Portable Executable Image...

How can I determine for which platform an executable is compiled?
