Runtime error:zero-dimensional tensor(at position 0) cannot be contatenated

[Llq201809]

when I run train_p_net.py ,it shows these error:
Traceback (most recent call last):

Hello, I have the same problem.Have you saved it?

Thank,I have solved it.

change the error line into accuracy_avg = torch.mean(torch.stack(accuracy_list, dim=0))
