opencv2.4.3在OSX 10.7上读写OpenEXR时抛出错误

Question

我正在OSX 10.7.5上运行OpenCV（2.4.3）的brew安装。我尝试过brew安装OpenEXR（1.7.0）并下载其源代码并直接编译1.7.1，因为我读到它的接口可能有一些更改。OpenEXR的两个版本都允许我在预览中打开EXR文件。每次新安装OpenEXR之后，我都会回去卸载OpenCV并重新安装。OpenCV正在检测正确的OpenEXR：

--   Media I/O: 
--     ZLib:                        /usr/lib/libz.dylib (ver 1.2.5)
--     JPEG:                        /usr/local/lib/libjpeg.dylib (ver 80)
--     PNG:                         /usr/X11/lib/libpng.dylib (ver 1.5.4)
--     TIFF:                        /usr/local/lib/libtiff.dylib (ver 42 - 4.0.3)
--     JPEG 2000:                   /usr/local/lib/libjasper.dylib (ver 1.900.1)
--     OpenEXR:                     build (ver 1.7.1)

当我尝试在python中通过cv2读或写EXR时

具体来说，这些错误是由于：

import cv2
cv2.imread("image.exr")

有什么建议吗？在

编辑：我还试图从OpenCV网站重新编译2.4.3的源代码，但遇到了完全相同的问题。在

Answer 1

通过回滚到opencv2.4.2解决了这个问题。似乎他们已经将openexr1.7.1与2.4.3发行版捆绑在一起，但是它不起作用。此外，2.4.3似乎无法检测到OpenEXR的早期版本。在
