类型错误：“Image”和“int”的实例之间不支持“>”

如何解决类型错误：“Image”和“int”的实例之间不支持“>”

我正在尝试编写一个 if 语句，如果列表索引超出范围，则会出现中断。 我不确定如何解决此错误。 我是 python 和 classess 的新手。 它在列表中保存为 PIL 图像。 错误：

/content/drive/MyDrive/triangles_pieces_dataset.py in slice_and_Create(self)
    349                             yield (horizontal_torch_neg,negative_label)
    350                             yield (vertical_torch_neg,negative_label)
--> 351                         if (listimagesTwo[l+2] > len(listimagesTwo)) or (listimages[k+1] > len(listimages)):
    352                           break
    353                         else:

TypeError: '>' not supported between instances of 'Image' and 'int'

发生错误的方法：

有人可以帮我解决这个问题吗？

解决方法

问题是由于类似的说明

if (listImagesTwo[l+2] > len(listImagesTwo))

您正在将 PIL.Image 对象 (listImagesTwo[l+2]) 与 int (len(listImagesTwo)) 进行比较。正如错误消息指出的那样。

有几种可能性可以修复。无论如何，您已经在两个列表之间循环，因此不需要 break 指令。
