CUDA error: device-side assert triggered

[Mantee0810]

Hi author, I have used this code to train on the VOC dataset with very good results. But when I try to train on Cityscapes dataset, I have the following problem, do you have any thoughts on this? Looking forward to your reply.

Could you provide a detailed configuration of your setting? For example, the config.yaml, how many GPUs did you use

Hello, I'm having the same problem, how can I fix this please, I'm only running the Cityscapes dataset.
