用python的话，直接pip install 安装：

python -m pip install paddlepaddle==2.3.0
python -m pip install paddleocr

然后再python中运行：

#test.py

from paddleocr import PaddleOCR

import cv2
import numpy as np

ocr = PaddleOCR(use_angle_cls=True, use_gpu=False, enable_mkldnn=True)

image = cv2.imread("3.jpg")

result = ocr.ocr(dst, cls=True)
for line in result:
    print(line)
