when I use python3 PPOCRLabel.py to start it, I meet this question as I description. I have checked all the qt libary have been perpared. So, what's the reason caused this bug?

Evezerest commented 3 years ago

Do you run PPOCRLabel on Linux? What version of qt have you installed？

@Evezerest @Harrisonyong Hi, I have the same problem， So how do we solve this？Please help me

mohandeepzumen commented 2 years ago

@Evezerest my qt version is qt5, I used pip install PyQt5

mohandeepzumen commented 2 years ago

Just resolved it. Install opencv in the same env where you installed paddle paddle. use "pip install opencv-python==4.2.0.32". Doing this resolved for me

liguiyuan commented 2 years ago

I have solved this problem, reduce the opencv-python version : pip3 install --upgrade opencv-python==4.2.0.32
