I was getting the same issue (which hadn't happened before, I have no idea how this broke out of nowhere)

Fixed it with the pip install opencv-python-headless==4.5.1.48 @Aslyamovt mentioned and was changed in https://github.com/xuyichenmo/EasyOCR/commit/3333f241349ddaf45477cc1bcda768da56d338dd

Hi all, I am getting the same issue, but issue does not fix by changing opencv-python-headless and opencv-python versions to either 4.5.1.48 nor 4.5.4.60.

I meet the same problem, and it works to use opencv-python==4.5.1.48. Thanks!
