Qt xcb error?

[GalSang17]

(py38) yangyang@ysd:~$ anylabeling QObject::moveToThread: Current thread (0x55efb47d7980) is not the object's thread (0x55efb56c97e0). Cannot move to target thread (0x55efb47d7980)

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/yangyang/miniconda3/envs/py38/lib/python3.8/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.

my envs: python=3.8 PyQt=5.15.7

@GalSang17 You can try the following commands:

pip uninstall opencv-python
pip uninstall opencv-contrib-python
pip install opencv-python-headless

yeah! it worked, just i can open this software, if i try to label anything by load a sam model, an error about cv2 will throw, so, if this software must use cv2, why unistall opencv-python , then can open this software?

@GalSang17 OpenCV has 4 packages for python: opencv-python, opencv-contrib-python, opencv-python-headless and opencv-contrib-python-headless. The first two versions may cause some issues on some machines, mostly when used with PyQt.

[vietanhdev]

Install the headless version to use cv2:

pip install opencv-python-headless

Or

opencv-contrib-python-headless
