readtext doesn't work with latest opencv version

See original GitHub issue

Windows 10 64bit easyocr 1.4.1 opencv-python 4.5.5.62

Problem

When using reader.readtext I was getting an error message from opencv

\lib\site-packages\easyocr\craft_utils.py", line 31, in getDetBoxes_core
    nLabels, labels, stats, centroids = cv2.connectedComponentsWithStats(text_score_comb.astype(np.uint8), connectivity=4)
cv2.error: Unknown C++ exception from OpenCV code

Solution

Spent most of my day trying to fix whatever was wrong with connectedComponentsWithStats… Issue didn’t go away no matter what I did until I switched from opencv-python version 4.5.5.62 to version 4.5.4.60 .

I know this is a opencv problem so you can’t do much about, but probably should limit the opencv version until they fix

Hi, Please change the opencv-python version to 4.5.4.60. Try this command,

!pip uninstall opencv-python
!pip install opencv-python==4.5.4.60 easyocr

then, you will use readtext thank you
