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：centos7

• 版本号/Version：Paddle：paddlepaddle-gpu 2.5.2.post112
  PaddleOCR：2.7.0.3
  问题相关组件/Related components：

• 运行指令/Command Code：
  ocr = PaddleOCR(use_angle_cls=False,
  lang="ch",
  det_model_dir = det_model_dir,
  rec_model_dir = rec_model_dir,
  cls_model_dir = None,
  det_db_thresh=0.3,
  det_db_box_thresh=0.6
  )
  det_model_dir为训练的mv3db模型
  rec_model_dir为训练的rec_svtrnet_ch模型
  使用ch_PP-OCRv4_rec识别模型不会报错，调整了rec_svtrnet_ch.yml中的尺寸[3,32,320]为[3,48,320]重新训练模型也不能解决问题
  似乎对于不同的输入图片，已有代码不能自动处理成合适的大小供rec_svtrnet_ch模型推理.
