问题描述

执行启动的时候报错

QObject::moveToThread: Current thread (0xb75d00) is not the object's thread (0x4cb65f0).
Cannot move to target thread (0xb75d00)

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "/home/dev/anaconda3/envs/38/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.

问题分析

看错误提示应该是缺少了Qt的环境变量设置，按照要求设置一下。

解决方案

设置环境变量

export QT_QPA_PLATFORM=wayland

echo $QT_QPA_PLATFORM
wayland

然后再次启动

PPOCRLabel --lang ch --kie True
