list index out of range

[wangaixue]

I follow Non-distributed training to train all dataset. but when some time, the programe will interrupt. The question is IndexError: list index out of range. Can you tell me how to solve this question? Is the dataset is something wrong? @huanglianghua Thank you very much

@wangaixue Hi, can you provide more details on the reported error? For example, at which line of the code the running stopped?

@huanglianghua the question like this

I guess the rand_x is out the image_file? Can you help me? very thank you

@huanglianghua I also find this question when i only use the got-10k to train.
