我已经执行了neuralnetwork_tutorial.lua。现在我有了模型，我想用我自己的一些手写图像来测试它。但是我已经尝试了很多方法来存储权重，现在通过使用torch save 和 load 方法存储完整的模型。

但是现在我尝试使用预测我自己的手写图像（转换为 28X28 DoubleTensor）model:forward(testImageTensor)

你有两个选择。

一。使用封装的nn.Module转发您的torch.Tensor：

mlp2 = mlp:toModule(datasource:trainSet():sub(1,2))
input = testImageTensor:view(1, 1, 32, 32)
output = mlp2:forward(input)

二。将您的 torch.Tensor 封装到dp.ImageView并通过您的dp.Model 转发：

inputView = dp.ImageView('bchw', testImageTensor:view(1, 1, 32, 32))
outputView = mlp:forward(inputView, dp.Carry{nSample=1})
output = outputView:forward('b')
