请提供下述完整信息以便快速定位问题/Please provide the following information to quickly locate the problem

系统环境/System Environment：win10
版本号/Version：Paddle： PaddleOCR：问题相关组件/Related components：paddleocr2.7
运行指令/Command Code：import os os.environ["KMP_DUPLICATE_LIB)OK"]="TRUE" from paddleocr import PaddleOCR

初始化OCR模型

ocr = PaddleOCR(use_angle_cls=True, lang="ch")

图像路径

img_path = 'D:/download/身高体重.png'

进行OCR识别

result = ocr.ocr(img_path, cls=True)

提取识别结果并保存成文本文件

output_file = 'D:/download/身高体重.txt' # 指定保存文本的文件名 with open(output_file, 'w', encoding='utf-8') as f: for res in result: for line in res: f.write(line[1][0] + '\n')

显示结果

from PIL import Image from paddleocr import draw_ocr

image = Image.open(img_path).convert('RGB') boxes = [line[0] for res in result for line in res] txts = [line[1][0] for res in result for line in res] scores = [line[1][1] for res in result for line in res] im_show = draw_ocr(image, boxes, txts, scores, font_path='./fonts/simfang.ttf') im_show = Image.fromarray(im_show) im_show.save('result2.jpg')
