RuntimeError: Expected object of type torch.cuda.FloatTensor but found type torch.FloatTensor for ar

这行报错predict = model(Variable(x_train))

RuntimeError: Expected object of type torch.cuda.FloatTensor but found type torch.FloatTensor for argument #4 'mat1'

意思是要求的目标类型是torch.cuda.FloatTensor，但是找到的数据类型是torch.FloatTensor，所以需要在数据类型后面加上.cuda()。将predict = model(Variable(x_train)) 改为predict = model(Variable(x_train.cuda()))
