cannot detect text " Since the angle classifier is not initialized, it will not be used during the forward process "

[namaws]

Hello,

I want to use paddleocr to detect text from image. However I keep getting this warning and not really detecting any text.
(the testing image here was from an example of people using paddleocr to do text recognition, so it should be able to detect)

ocr_model = PaddleOCR(lang='en', cls=False)

ppocr WARNING: Since the angle classifier is not initialized, it will not be used during the forward process is just a warning.
Looking at the output log, 6 text boxes have been successfully predicted. You can continue to print the result to confirm the correctness.

hey, i was facing the same thing. you said it was just a warning. can you tell me more about what the difference in initializing or not initializing this angle classifier?

I got rid of Debug and ppocr WARNING messages using the below code:

Initialize PaddleOCR with English language support

ocr = PaddleOCR(use_angle_cls=True, lang='en', show_log = False)
