问题描述
想安装 PaddleOCR 的标注工具用,系统环境 ubuntu20.04/18.04 都试过, 按照教程,在conda环境里面直接:
pip install pyqt5
cd ./PPOCRLabel # 切换到PPOCRLabel目录
python PPOCRLabel.py --lang ch
结果报错显示:
QObject::moveToThread: Current thread (0x55d47a28a540) is not the object's thread (0x55d47a3a1be0).
Cannot move to target thread (0x55d47a28a540) qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/gpu-server/anaconda3/envs/ppocr_hq/lib/python3.7/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. --------------------------------------
C++ Traceback (most recent call last):
--------------------------------------
No stack trace in paddle, may be caused by external reasons. ----------------------
Error Message Summary:
----------------------
FatalError: `Process abort signal` is detected by the operating system. [TimeInfo: *** Aborted at 1645608694 (unix time) try "date -d @1645608694" if you are using GNU date ***] [SignalInfo: *** SIGABRT (@0x3e8000014dd) received by PID 5341 (TID 0x7f36115bb0c0) from PID 5341 ***] Aborted (core dumped)
按照网上教程,使用ldd 查过xcb 的链接库,发现没有问题.
解决方法
最后发现这个报错是 opencv 4.5 和 pyqt5 有冲突.解决方法是要么使用opencv-headless,要么使用conda安装pyqt5
我的解决方法是:
pip uninstall pyqt5
pip uninstall pyqt5-sip
conda install pyqt
