关于系统提示FatalError: Process abort signal is detected by the operating system.

[WilliamGrant]

我发现我在启动PPOCRLabel时，出现了如下情况

Got keys from plugin meta data ("xcb")
QFactoryLoader::QFactoryLoader() checking directory path "/home/Mashiro/.pyenv/versions/3.10.10/bin/platforms" ...
qt.qpa.plugin: Could not find the Qt platform plugin "dxcb" in "/media/Mashiro/inst_47/Project/python/PPOCRLabel/.venv/lib/python3.10/site-packages/cv2/qt/plugins"

QObject::moveToThread: Current thread (0x55a96abfda50) is not the object's thread (0x55a9704e3da0).
Cannot move to target thread (0x55a96abfda50)

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/media/Mashiro/inst_47/Project/python/PPOCRLabel/.venv/lib/python3.10/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, linuxfb, minimal, offscreen, vnc, webgl.

使用的环境是deepin v23 社区版本，不知道是否跟本机或者和开发环境有关，我不太会搭这个配置环境，还望指出问题所在。

I have exactly the same issue with the same error message here.

Thanks - after uninstalling opencv-python and installing opencv-python-headless it works now for me 👍

[WilliamGrant]

确实如此，使用opencv-python-headless 确实可以避免这个错误的出现。谢谢解答。
