读写Mnist保存为指定格式，图像数据如下：链接：https://pan.baidu.com/s/11UBOdsZ9FYi7PR0bGkn-JQ  提取码：y4v8

1. dev_update_off()
   
2. * 图像路径
   
3. path := 'D:/2-LearningCode/999-AI-Pytorch/10_OCR_Pytorch/OCR_Dataset/mnist-master/MNIST_data/Train/train'
   
4. * txt文本，每张图对应的label标签
   
5. train_label := 'D:/2-LearningCode/999-AI-Pytorch/10_OCR_Pytorch/OCR_Dataset/mnist-master/MNIST_data/Train/train_label.txt'
   
6. * 创建存储txt
   
7. File_Name := 'MNIST_data_train.txt'
   
8. file_exists(File_Name,FileExits)
   
9. if(FileExits)
   
10.     open_file(File_Name,'append',FileHandle_train)
    
11. else
    
12.     open_file(File_Name,'output',FileHandle_train)
    
13. endif
    
14. list_image_files(path, 'default', [], ImageFiles)
    
15. * 读取train_label
    
16. open_file (train_label, 'input', FileHandle)
    
17. IsEOF := 0
    
18. nums := []
    
19. while (IsEOF == 0)
    
20.     fread_string (FileHandle, Number, IsEOF)
    
21.     tuple_split(Number, '\n', Substrings)
    
22.     if(|Substrings|>0)
    
23.         tuple_split(Substrings[0], ',', Substrings1)
    
24.         for i:= 0 to |ImageFiles|-1 by 1
    
25.             OCR_image_abspath := path + '/' + i + '.png'
    
26.             OCR_info := number(Substrings1[i])
    
27.             fwrite_string(FileHandle_train, OCR_image_abspath + ',' + OCR_info + '\n')
    
28.         endfor
    
29.     endif
    
30. endwhile
    
31. close_file (FileHandle)
    
32. close_file (FileHandle_train)

结果如下：

1. D:/2-LearningCode/999-AI-Pytorch/10_OCR_Pytorch/OCR_Dataset/mnist-master/MNIST_data/Train/train/0.png,5
   
2. D:/2-LearningCode/999-AI-Pytorch/10_OCR_Pytorch/OCR_Dataset/mnist-master/MNIST_data/Train/train/1.png,0
   
3. D:/2-LearningCode/999-AI-Pytorch/10_OCR_Pytorch/OCR_Dataset/mnist-master/MNIST_data/Train/train/2.png,4
   
4. D:/2-LearningCode/999-AI-Pytorch/10_OCR_Pytorch/OCR_Dataset/mnist-master/MNIST_data/Train/train/3.png,1
   
5. D:/2-LearningCode/999-AI-Pytorch/10_OCR_Pytorch/OCR_Dataset/mnist-master/MNIST_data/Train/train/4.png,9
   
6. D:/2-LearningCode/999-AI-Pytorch/10_OCR_Pytorch/OCR_Dataset/mnist-master/MNIST_data/Train/train/5.png,2
