我正在移植一个在Windows上开发的python + opencv应用程序到mac。
在Windows上,我的virtualenv网站包中有cv2.pyd,它很顺利。
我是mac新手,我不明白它应该有效。我没有找到任何opencv python绑定的二进制文件,似乎正在使用macport。
macport正在复制opts /.../ site-packages中的cv.py和cv2.so。
此时如何使用它?
我尝试手动复制这两个文件,但收到错误
>>> import cv
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/cv.py", line 1, in <module>
from cv2.cv import *
ImportError: dlopen(/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/cv2.so, 2): no suitable image found. Did find:
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/cv2.so: mach-o, but wrong architecture
怎么了?
更新: 正如@Vortexfive所说:
$ file /Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/cv2.so
/Library/Frameworks/Python.framework/Versions/2.6/lib/python2.6/site-packages/cv2.so: Mach-O 64-bit dynamically linked shared library x86_64
$ file /Library/Frameworks/Python.framework/Versions/2.6/bin/python
/Library/Frameworks/Python.framework/Versions/2.6/bin/python: Mach-O universal binary with 2 architectures
/Library/Frameworks/Python.framework/Versions/2.6/bin/python (for architecture ppc): Mach-O executable ppc
/Library/Frameworks/Python.framework/Versions/2.6/bin/python (for architecture i386): Mach-O executable i386
似乎存在不匹配。如何解决?
答案 0 :(得分:1)
目标体系结构似乎不匹配。您可以尝试使用+ universal变体在macports中安装opencv。
另一种选择是更新您的Python版本。我相信也会为x86_64编译更新的版本。
作为第三种选择,您可以在macports中使用+ python27安装opencv。然后,您可以通过sudo port select python27
选择Python的macports版本。

在我的情况下,拱门匹配:
$ file ../../release.mac/lib/cv2.so
../../release.mac/lib/cv2.so: Mach-O 64-bit dynamically linked shared library x86_64
$ file `which python`
/usr/bin/python: Mach-O universal binary with 2 architectures
/usr/bin/python (for architecture x86_64): Mach-O 64-bit executable x86_64
/usr/bin/python (for architecture i386): Mach-O executable i386
但不知道python是以32位模式运行的:
$ defaults read com.apple.versioner.python Prefer-32-Bit
1
修正:
$ VERSIONER_PYTHON_PREFER_32_BIT=0 python
或
$ defaults write com.apple.versioner.python Prefer-32-Bit -bool no
