TypeError: item() takes no argum

python报错

Traceback (most recent call last):

  File "main.py", line 152, in <module>

    train(epoch)

  File "main.py", line 120, in train

    100. * batch_idx / len(train_loader), loss.item(0)))

TypeError: item() takes no arguments (1 given)

解决方法：

将item(0)改为item()
