import cv2 error : dll load failed

我的环境:
python 3.6.5
windows 2008 r2 enterprise

我通过

 pip install opencv-python
pip install opencv-contrib-python

安装opencv 然后当我导入cv2的时候却出现了如下的错误

 In [2]: import cv2
---------------------------------------------------------------------------
ImportError                               Traceback (most recent call last)

ImportError: DLL load failed: 找不到指定的模块。

查找了很多的资料我尝试去下载安装C++ Redistributable Package的各个版本并且去更新系统和去https://www.lfd.uci.edu/~gohlke/pythonlibs/上下载对应whl文件来安装仍旧不能解决这个问题,奇怪的是在我的win7上安装opencv然后导入就没有问题,难道是系统的问题?那么我该如何去查找问题的根源并且去解决呢 万分感谢

windows 2008 r2 enterprise 系统无法解决此问题 只能换成win10系统

https://pypi.org/project/opencv-python/
这里有提到这个问题:
Q: Import fails on Windows: ImportError: DLL load failed: The specified module could not be found.?

A: If the import fails on Windows, make sure you have Visual C++ redistributable 2015 installed. If you are using older Windows version than Windows 10 and latest system updates are not installed, Universal C Runtime might be also required.

问:导入失败在Windows: ImportError: DLL加载失败:指定的模块找不到。
答:如果在Windows上导入失败,请确保安装了Visual c++ redistributable 2015。如果您使用的是比windows10更老的Windows版本,并且没有安装最新的系统更新,则可能还需要Universal C Runtime。

If the above does not help, check if you are using Anaconda. Old Anaconda versions have a bug which causes the error, see this issue for a manual fix.

如果上面的方法不起作用,检查你是否在使用Anaconda。旧的Anaconda版本有一个导致错误的错误,请参阅此问题以获得手动修复。

volatile 与 synchronize 详解
Java支持多个线程同时访问一个对象或者对象的成员变量,由于每个线程可以拥有这个变量的拷贝(虽然对象以及成员变量分配的内存是在共享内存中的,但是每个执行的线程还是可以拥有一份拷贝,这样做的目的是加速程序的执行,这是现代多核处理器的一个显著特性),所以程序在执行过程中,一个线程看到的变量并不一定是最新的。 volatile 关键字volatile可以用来修饰字段(成员变量),就是告知程序任何对该变量...
Java学习的正确打开方式
在博主认为,对于入门级学习java的最佳学习方法莫过于视频+博客+书籍+总结,前三者博主将淋漓尽致地挥毫于这篇博客文章中,至于总结在于个人,实际上越到后面你会发现学习的最好方式就是阅读参考官方文档其次就是国内的书籍,博客次之,这又是一个层次了,这里暂时不提后面再谈。博主将为各位入门java保驾护航,各位只管冲鸭!!!上天是公平的,只要不辜负时间,时间自然不会辜负你。 何谓学习?博主所理解的学习,它是一个过程,是一个不断累积、不断沉淀、不断总结、善于传达自己的个人见解以及乐于分享的过程。

程序员接私活怎样防止做完了不给钱?
