    client = vision.ImageAnnotatorClient()

    # The name of the image file to annotate
    file_name = os.path.abspath("v2i/%d.png"%(i))

    # Loads the image into memory
    
    with io.open(file_name, 'rb') as image_file:
        content = image_file.read()

        vertices = (['({},{})'.format(vertex.x, vertex.y)

        f = open(filename, 'w')
        f.write(write1[i])
        f.write(write2[i])
        f.close()
       

    if response.error.message:
        raise Exception(
            '{}\nFor more info on error messages, check: '
            'https://cloud.google.com/apis/design/errors'.format(

    #指定文字檔路徑

    #f = open(filename, 'w')

    #f.write(write1[i])
    #f.write(write2[i])
    
    #f.close()

我的目标是使用google视觉将多张照片转换成多个文本文件，但是在转换过程中（在for循环中）我一直遇到一个bug"runfile('/home/lab/chinese/i2tvision .py', wdir= '/home/lab/chinese') 回溯（最近调用最后）：

文件“/home/lab/chinese/i2tvision.py”，第 50 行，位于 f.write(write1[i])

IndexError: 列表索引超出范围" 有什么方向可以解决这个问题吗？谢谢

Answer 1

您根本不需要这两个列表。只需在生成它们时写下这些行。

    f = open(filename, 'w')    
    for text in texts:        
        f.write('\n"{}"'.format(text.description))  
        vertices = (['({},{})'.format(vertex.x, vertex.y)
                      for vertex in text.bounding_poly.vertices])
        f.write('bounds: {}'.format(','.join(vertices)))
    f.close()
