qt报错： Could not load the Qt platform plugin "xcb"

QObject::moveToThread: Current thread (0x2550470) is not the object's thread (0x3fa6050).
Cannot move to target thread (0x2550470)

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/hs/dl/env/miniconda3/envs/pytorch-cp311-cu121/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, linuxfb, minimal, offscreen, vnc, webgl.

已中止 (核心已转储)

sudo apt install libxcb-* 无效

https://www.jb51.net/article/193024.htm 无效

opencv qt冲突 有效
pip install opencv-python-headless

将qt so路径加入环境变量
vim ~/.bashrc
尾部添加
export QT_QPA_PLATFORM_PLUGIN_PATH=/path/to/qt/plugins/platforms
更新
source ~/.bashrc

有so文件缺失 从gnu中copy
ldd xx.so | grep "not found"排查缺失依赖，install
