I saved my net now the way you told me to do it. You can see it below.
torch.save(net.state_dict(),'VGGNet11.pt')

And now I want to load the net in another python file. The Pytorch help page says that you have to load the net like this:
net = TheModelCLass(*args, **kwargs)
net.load_state_dict(torch.load('VGGNet11.pt'))

What do they mean with TheModelCLass?
