mask-rcnn image_id问题

问题遇到的现象和发生背景

在使用mask-rcnn的时候出现以下报错，好久没有解决了，有偿

用代码块功能插入代码，请勿粘贴截图

process Process-1:
Traceback (most recent call last):
File "/root/miniconda3/lib/python3.6/site-packages/mrcnn/model.py", line 1695, in data_generator
image_index = (image_index + 1) % len(image_ids)
ZeroDivisionError: integer division or modulo by zero

During handling of the above exception, another exception occurred:

我的解答思路和尝试过的方法

看了自己的标签发现没有问题，卡在这一步了，现在是凌晨五点，有点难受

UnboundLocalError: local variable 'image_id' referenced before assignment
UnboundLocalError:赋值前引用了局部变量“image_id”
你的报错主要是因为在函数内部对变量赋值进行修改后，该变量就会被Python解释器认为是局部变量而非全局变量
借用这篇博文的解题思路，看是否对你有所帮助：https://blog.csdn.net/weixin_45666566/article/details/116460400

这篇文章详细得写了 mask-rcnn image_id得一些问题，
希望对你有所帮助，有问题可以一起探讨
