如题，使用labelme报错。
You might be loading two sets of Qt binaries into the same process. Check that all plugins are compiled against the right Qt binaries. Export DYLD_PRINT_LIBRARIES=1 and check that only one set of binaries are being loaded.

Class QMacAutoReleasePoolTracker is implemented in both /usr/local/opt/qt/lib/QtCore.framework/Versions/5/QtCore (0x109258978) and /usr/local/lib/python3.7/site-packages/cv2/.dylibs/QtCore (0x11aac5700). One of the two will be used. Which one is undefined.

原因是我在安装labelme时安装过qt，但在之后的opencv的安装包中也有qt，解决方法很简单，把报错中的qtcore删除就正常了。
