about single GPU

[Catherinehui]

Hello, I recently found a problem when reproducing the experimental results, the original was to use multi-GPU training, but these two days, the resources are limited, and found that the model can not run normally on a single gpu training, may I ask you have encountered this problem, do you have a single gpu training version, thank you very much, here is my error:
Traceback (most recent call last):

Hello.
I'm guessing that the error you're experiencing is due to converting code written for multiple GPUs to a single GPU environment.
I will update the ExU-Net training code for a single GPU as soon as possible.
