I should using GPU, bur ERROR about pytorch-transfomer

[KK-xi]

I using GPU, so model.cuda()
and train.cuda()

but, this error

Traceback (most recent call last):

Change the network ??

When defining Transformer in the Network.py file, you need to change self.encs=[] to self.encs=nn.ModuleList([]), I solved this problem by this way.
