🌰 Minimal Reproducible Example (最小可复现问题的Demo)

from paddleocr import PaddleOCR, draw_ocr

Paddleocr supports Chinese, English, French, German, Korean and Japanese

You can set the parameter lang as ch, en, french, german, korean, japan

to switch the language model in order

ocr = PaddleOCR(use_angle_cls=True, lang='en') # need to run only once to download and load model into memory
img_path = 'PaddleOCR/doc/imgs_en/img_12.jpg'
result = ocr.ocr(img_path, cls=True)
for idx in range(len(result)):
res = result[idx]
for line in res:
print(line)

Please check the version of CUDA. You can refer to this link for installation:https://www.paddlepaddle.org.cn/install/quick?docurl=/documentation/docs/zh/develop/install/pip/linux-pip.html

[dexforint]

Same problem, environment: Kaggle
Solution for me

!pip install paddlepaddle-gpu==3.0.0rc1 -i https://www.paddlepaddle.org.cn/packages/stable/cu118/
!pip install paddleocr

hi, Please ensure that your drivers can at least meet the CUDA version requirements corresponding to the version of Paddle you have downloaded.
