bug -- Pyqt5+openCV报错(QObject::moveToThread:)
报错什么线程无法移动，妈个鸡狗屁不是
使用pyqt和opencv的做的GUI程序中出线的问题
就是opcv-python的版本对不上
| 系统 | py版本（conda） | 报错 |
|---|---|---|
| Ubuntu21 | 3.9 | Cannot move to target thread |
QObject::moveToThread: Current thread (0x5560b72388b0) is not the object's thread (0x5560b74641b0).
Cannot move to target thread (0x5560b72388b0)
这个报错是上面的报错引起的
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/fly/anaconda3/envs/video/lib/python3.9/site-packages/cv2/qt/plugins" even though it was found.
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.（
Available platform plugins are: xcb, eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl.
解决方案：降版本，网上的都是说降opencv版本，这里推荐降python（血泪记忆）
opencv-python4.1.2.30
把上面的文件下载，本地安装即可(虚拟环境切换到相应的虚拟环境)
pip install opencv_python-4.1.2.30-cp38-cp38-manylinux1_x86_64.whl
成功解决
