1 year ago I recently wrote up a set of debugging instructions for this:
Check 1
Again run:
pip uninstall python-opencv
pip uninstall python-opencv
pip uninstall python-opencv-headless
pip uninstall python-opencv-headless(As shown run each command twice to ensure there are not duplicates)
Now pip install python-opencv-headless. And check if that works.
If it breaks, rerun ibeis, but run:
export QT_DEBUG_PLUGINS=1
first to get more verbose output from PyQt and rerun ibeis.
Check 2
If that doesn't work let's dive deeper and debug it. I put together the following script that will provide me with more information I can use to help diagnose your problem.
#!/bin/bash
__doc__="
These are steps to help debug opencv / pyqt5 issues
"
# Where are your Python site packages?
PYTHON_SITE_PACKAGE_DPATH=$(python -c "import sysconfig; print(sysconfig.get_paths()['platlib'])")
echo "PYTHON_SITE_PACKAGE_DPATH = $PYTHON_SITE_PACKAGE_DPATH"
# Running X or Wayland?
echo "$XDG_SESSION_TYPE = $$XDG_SESSION_TYPE"
# Where is the cv2 library located
OPENCV_MODULE_DPATH=$(python -c "import cv2; print(cv2.__file__)")
echo "OPENCV_MODULE_DPATH = $OPENCV_MODULE_DPATH"
# What opencv packages do you have installed in site packages?
find "$PYTHON_SITE_PACKAGE_DPATH" -maxdepth 1 -iname "*opencv*"
ls "$PYTHON_SITE_PACKAGE_DPATH"/opencv_python_headless.libs
# Where is PyQt5?
PYQT_MODULE_DPATH=$(python -c "import PyQt5; print(PyQt5.__file__)")
echo "PYQT_MODULE_DPATH = $PYQT_MODULE_DPATH"Check 3
The above information should be enough, but if not there is additional information that might be useful:
#### If the above is still unclear, the kwimage / kwplot modules have useful
#### helpers for debugging pyqt issues.
# install kwimage / kwplot
pip install kwimage[headless] kwplot xdoctest
# Run the kwplot pyqt tests
export QT_DEBUG_PLUGINS=1
xdoctest -m kwplot.auto_backends autompl --check
KWPLOT_UNSAFE=1 xdoctest -m kwplot.auto_backends autompl --check
KWPLOT_UNSAFE=0 xdoctest -m kwplot.auto_backends autompl --check

Hi, hope you can assist? Thanx!
opencv-python was un installed and opencv-python-headless installed.
Warning: Ignoring XDG_SESSION_TYPE=wayland on Gnome. Use QT_QPA_PLATFORM=wayland to run on Wayland anyway. qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" 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: eglfs, linuxfb, minimal, minimalegl, offscreen, vnc, wayland-egl, wayland, wayland-xcomposite-egl, wayland-xcomposite-glx, webgl, xcb.
