when i run the gan_lstm.py an error happened

[Lvhhhh]

So basically you have to use .item() as follows instead of using .data[0]. This is actually for new version of torch.
D_cost = fake_loss_48.item() + fake_loss_32.item() + fake_loss_16.item() + fake_loss_0.item()

老哥，你用的数据集是巴黎街道吗，是自己把它crop成了128X128？ 我也是这个问题
