python下openCV与Qt冲突？

Question

同时引用了opencv和qt，运行报错如下：

...
objc[4316]: Class QNSImageView is implemented in both /usr/local/lib/python3.6/site-packages/cv2/.dylibs/QtGui (0x112ff5350) and /usr/local/Cellar/qt/5.10.0_1/plugins/platforms/libqcocoa.dylib (0x11636d700). One of the two will be used. Which one is undefined.
...

看样子是因为openCV内部已经有了qt这个lib，但是qt里面也有这个lib，程序就不知道引用哪一个了。去掉import cv2后恢复正常。

不知有没有大神指导如何解决这个问题？

实验源码如下：

import cv2
from PyQt5.QtWidgets import QApplication
import sys

def main():
    app = QApplication(sys.argv)

if __name__ == "__main__":
    main()
