问题描述
我在同一个conda虚拟环境中拥有PyQt5和OpenCV.
I have PyQt5 and OpenCV in the same conda virtual environment.
opencv-python==3.4.1.15
PyQt5==5.10.1
每当我运行PyQt5应用程序时,都会收到类似以下的警告:
Whenever I run my PyQt5 app, I get many warnings like these:

处理此问题的适当方法是什么?
What is the appropriate way to handle this?
推荐答案
我通过使用GUI卸载opencv并安装无头版本来解决了这个问题:
I solved the problem by uninstalling opencv with the GUI and installing the headless version:
pip卸载opencv-contrib-python
pip uninstall opencv-contrib-python
pip安装opencv-contrib-python-headless
pip install opencv-contrib-python-headless
opencv中的namedWindow函数仍然有效.
The namedWindow function in opencv still works.
