First said the background
Windows 7, there is no problem but only on the Windows server 2008 r2 enterprise out of the question so my feeling is related to system
To rule out other problems I made the following methods:
Python version 3.6 is installed the first Visual c + + redistributable, 2015 systems are also updated
Whether through
PIP install opencv - python
PIP install opencv - contrib - python
Or through corresponding WHL installation downloaded from https://www.lfd.uci.edu/~gohlke/pythonlibs/
Import will still produce the following error when

C: \ Users \ \ Administrator \ Desktop> Ipython

3.6 corresponds to 36 WHL question I don't think the Windows 7 useless WHL is no problem

CodePudding user response:

Server 2008 with PIP might misjudge the operating system installation, led to the download version mismatch, download, should according to download on the python version, you have the latest file name cp36 and amd64 WHL installed should be able to solve the problem,
Install WHL process have error message?

According to the information of https://pypi.org/project/opencv-python/I installed the Visual c + + redistributable 2015

My system is a Windows server 2008 r2 enterprise do not know if the support version if support that shows that there are other questions if you don't support me how to find the corresponding "redistribution package

CodePudding user response:

With the Dependency Walker, review what is missing DLL

CodePudding user response:
