Bad file descriptor Error after finishing the training process

[Yassin-fan]

Thanks for your work!
I have tried to run this PSGTR on 3090 for 60 epochs.
I didn't change the code, but when it finished the training process, there is an error:

2023-05-03 21:09:11,872 - mmdet - INFO - Epoch(val) [60][2177] *****

During handling of the above exception, another exception occurred:

I searched this error and found that it is because the code somewhere has closed the connection prematurely?
Is there something wrong?
Thanks for your help.
