    <p>I'm running a brew install of OpenCV (2.4.3) on OSX 10.7.5. I've tried both the brew install of OpenEXR (1.7.0) and downloading their source and compiling 1.7.1 directly as I read there may've been some changes to its interface. Both versions of OpenEXR will let me open EXR files in Preview. After each new installation of OpenEXR, I've went back, uninstalled OpenCV and reinstalled it. OpenCV is detecting the correct OpenEXR:</p> <pre><code>-- 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) </code></pre> <p>When I try to read or write EXR through cv2 in python I get</p> <pre><code>terminate called throwing an exceptionAbort trap:6 </code></pre> <p>This is the full crash report:</p> <pre><code>Exception Type: EXC_CRASH (SIGABRT) Exception Codes: 0x0000000000000000, 0x0000000000000000 Application Specific Information: abort() called objc[52394]: garbage collection is OFF terminate called throwing an exception Thread 0 Crashed:: Dispatch queue: com.apple.main-thread 0 libsystem_kernel.dylib 0x00007fff8e43a82a __kill + 10 1 libsystem_c.dylib 0x00007fff8e012a9c abort + 177 2 libc++abi.dylib 0x00007fff8d2607bc abort_message + 214 3 libc++abi.dylib 0x00007fff8d25dfcf default_terminate() + 28 4 libobjc.A.dylib 0x00007fff944501cd _objc_terminate + 114 5 libc++abi.dylib 0x00007fff8d25e001 safe_handler_caller(void (*)()) + 11 6 libc++abi.dylib 0x00007fff8d25e05c std::terminate() + 16 7 libc++abi.dylib 0x00007fff8d25f152 __cxa_throw + 114 8 libopencv_highgui.2.4.dylib 0x000000010dc49d44 Iex::throwErrnoExc(std::string const&amp;, int) + 3492 9 libopencv_highgui.2.4.dylib 0x000000010dc4a8fc Iex::throwErrnoExc(std::string const&amp;) + 24 10 libopencv_highgui.2.4.dylib 0x000000010dc4c5e7 IlmThread::Semaphore::Semaphore(unsigned int) + 67 11 libopencv_highgui.2.4.dylib 0x000000010dc4b969 IlmThread::ThreadPool::Data::Data() + 27 12 libopencv_highgui.2.4.dylib 0x000000010dc4be74 IlmThread::ThreadPool::ThreadPool(unsigned int) + 46 13 libopencv_highgui.2.4.dylib 0x000000010dc4c260 IlmThread::ThreadPool::globalThreadPool() + 46 14 libopencv_highgui.2.4.dylib 0x000000010dc696aa Imf::globalThreadCount() + 9 15 libopencv_highgui.2.4.dylib 0x000000010dc3e38b cv::ExrDecoder::readHeader() + 35 16 libopencv_highgui.2.4.dylib 0x000000010dc2f54a _ZN2cvL7imread_ERKSsiiPNS_3MatE + 249 17 libopencv_highgui.2.4.dylib 0x000000010dc2f3d4 cv::imread(std::string const&amp;, int) + 132 18 cv2.so 0x000000010d4d28f4 _ZL15pyopencv_imreadP7_objectS0_S0_ + 332 19 org.python.python 0x000000010d19ed77 PyEval_EvalFrameEx + 13861 20 org.python.python 0x000000010d1a1cd8 PyEval_EvalCodeEx + 1996 21 org.python.python 0x000000010d1a1d4d PyEval_EvalCode + 54 22 org.python.python 0x000000010d1b908f 0x10d117000 + 663695 23 org.python.python 0x000000010d1ba671 PyRun_InteractiveOneFlags + 517 24 org.python.python 0x000000010d1ba79a PyRun_InteractiveLoopFlags + 214 25 org.python.python 0x000000010d1ba7fc PyRun_AnyFileExFlags + 63 26 org.python.python 0x000000010d1ca2af Py_Main + 2715 27 org.python.python 0x000000010d10fe88 0x10d10f000 + 3720 </code></pre> <p>Specifically, these errors are the result of:</p> <pre><code>import cv2 cv2.imread("image.exr") </code></pre> <p>Any suggestions?</p> <p>Edit: I've also attempted a fresh compilation of the source code for 2.4.3 from the OpenCV website and am encountering the exact same issue.</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
