Python“分段错误:11"；当运行“导入简历"时或“导入cv2" [英] Python "Segmentation fault: 11" when running "import cv" or "import cv2"

问题描述

我已经按照

I have installed numpy and opencv using macports as per these instructions, but when I try import cv or import cv2 I just get the segfault and I have no idea why.

有什么建议吗?

$ python
Python 2.7.6 (default, Sep  9 2014, 15:04:36) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv
Segmentation fault: 11

>>> import cv2
Segmentation fault: 11

对不起，细节太少了，但这是一台新计算机，我为此专门在上面安装了macports，而这是我在macports上安装的唯一内容，所以我不知道为什么这无法正常工作

Sorry there are so few details, but this is a new computer and I installed macports on it just for this, and these are the only things I've installed with macports, so I have no idea why this isn't working.

浏览崩溃报告，我发现:

Looking through the crash report I found this:

Exception Type:        EXC_BAD_ACCESS (SIGSEGV)
Exception Codes:       KERN_INVALID_ADDRESS at 0x0000000000000000

因此，在黑暗中拍摄时，我以超级用户身份运行python:

So, as a shot in the dark, I ran python as super user:

$ sudo python
Python 2.7.9 (default, Dec 13 2014, 15:13:49) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.56)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv
>>>

作为超级用户，一切似乎运行良好.这怎么可能?

As super user, everything appears to run fine. How is this possible?

推荐答案

如果您仔细查看python命令的信息消息，就会发现其中的区别.

If you look closely to the info message of your python command, you will see the difference.

从一辆越野车上来:

$ python
Python 2.7.6 (default, Sep  9 2014, 15:04:36) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv2
Segmentation fault: 11

在工作的人中:

$ sudo python
Python 2.7.9 (default, Dec 13 2014, 15:13:49) 
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.56)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> import cv
>>>

您的计算机上有两个不同的Python版本，它们可能会解释您的行为.

You have two different versions of Python on your machine which might explain the behaviors you got.
