我写了一个程序，使用 pyqt5 和 opencv-python 从相机捕捉视频，但是当我运行这个程序时，我得到:

cv2 和 pyqt5 冲突。
操作系统是macOS High Sieera，python版本是3.5.2，用venv搭建了一个虚拟环境，在里面执行“pip install pyqt5”、“pip install opencv-python”，库是安装。
在ubuntu和windows下都正常，没有报错，只有mac不行。
如何解决错误？
最佳答案
我的代码遇到了同样的问题。是因为opencv和pyqt5的冲突。我能够通过安装 opencv 的 headless 版本来解决问题
