训练模型导出为推理模型后，精度发生了变化

上图为训练模型推理结果

推理模型预测结果1（导出为静态图推理模型）：

导出推理命令：

python export_model.py -c /root/pyProjcet/PaddleOCR3.1/PaddleOCR/configs/det/PP-OCRv3/PP-OCRv3_mobile_det.yml -o Global.checkpoints=/root/pyProjcet/PaddleOCR3.1/PaddleOCR/myTest/project1/test/train/Train/best_accuracy.pdparams Global.save_inference_dir=/root/pyProjcet/PaddleOCR3.1/PaddleOCR/myTest/project1/test/train/Train Global.export_with_pir=False

推理模型预测结果2（导出为动态图推理模型）：

导出推理命令：

python export_model.py -c /root/pyProjcet/PaddleOCR3.1/PaddleOCR/configs/det/PP-OCRv3/PP-OCRv3_mobile_det_copy.yml -o Global.pretrained_model=/root/pyProjcet/PaddleOCR3.1/PaddleOCR/myTest/project1/test/train/Train/best_accuracy.pdparams Global.save_inference_dir=/root/pyProjcet/PaddleOCR3.1/PaddleOCR/myTest/project1/test/train/Train
