问题
以下是已翻译的内容：
有关此错误的现有帖子，但不与使用 matplotlib 结合使用。
QObject::moveToThread: 当前线程 (0x831f000) 不是对象的线程 (0x95b40e0)。无法移动到目标线程 (0x831f000)。qt.qpa.plugin：尽管已找到，但无法在“/home/me/miniconda3/envs/venv/lib/python3.9/site-packages/cv2/qt/plugins”中加载Qt平台插件“xcb”。此应用程序无法启动，因为无法初始化任何Qt平台插件。重新安装该应用程序可能会解决此问题。可用的平台插件包括：xcb、eglfs、minimal、minimalegl、offscreen、vnc、webgl。中止 (核心已转储)
英文:
There were existing posts regarding this error, but not in conjunction with using matplotlib.

Reinstalling the application may fix this problem.Available platform plugins are: xcb, eglfs, minimal, minimalegl, offscreen, vnc, webgl.Aborted (core dumped)

设置环境变量 QT_PLUGIN_PATH 可能会解决错误：
export QT_PLUGIN_PATH=/home/me/miniconda3/envs/venv/lib/python3.9/site-packages/cv2/qt/plugins
如果不行，安装依赖项：
sudo apt-get install libxcb1
pip install pyqt5
英文:
Setting the environment variable QT_PLUGIN_PATH, in terminal, may resolve the error:
export QT_PLUGIN_PATH=/home/me/miniconda3/envs/venv/lib/python3.9/site-packages/cv2/qt/plugins
If not, install the dependencies:
sudo apt-get install libxcb1
pip install pyqt5
