I am running a PySide2 (Qt5) application on a Raspberry Pi 5 with Raspberry Pi OS Lite (64-bit, November 2024 release). When I try to run my script (python main.py), I get the following error:
Got keys from plugin meta data ("xcb")
QFactoryLoader::QFactoryLoader() checking directory path "/usr/bin/platforms" ...
loaded library "/home/mindrontm/.local/lib/python3.11/site-packages/cv2/qt/plugins/platforms/libqxcb.so"
QObject::moveToThread: Current thread (0x2e862dc0) is not the object's thread (0x2e867840).
Cannot move to target thread (0x2e862dc0)
qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/mindrontm/.local/lib/python3.11/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.
Aborted
System Information Device: Raspberry Pi 5 OS: Raspberry Pi OS Lite (64-bit, November 2024) Python: 3.11 Qt Version: 5 (installed via system packages) PySide2 Version: Latest from pip
What I Have Tried
Forcing the correct Qt path:
export QT_QPA_PLATFORM_PLUGIN_PATH=/usr/lib/aarch64-linux-gnu/qt5/plugins/platforms
export QT_PLUGIN_PATH=/usr/lib/aarch64-linux-gnu/qt5/plugins
export QT_QPA_PLATFORM=xcb
python main.py
Running without OpenCV's path:
PYTHONPATH="" python main.py
Reinstalling OpenCV without Qt support:
pip uninstall opencv-python
pip install opencv-python-headless
Checking missing dependencies:
`ldd /usr/lib/aarch64-linux-gnu/qt5/plugins/platforms/libqxcb.so
Reinstalling Qt plugins:
sudo apt update
sudo apt install --reinstall qt5-qpa-platform-plugins
