How can i use MSE criterion? about torchnet

Sorry but this is for reporting issues in torchnet, not for general Torch questions.

I think the problem is still exist.

Yes, you cannot just use any criterion. The MNIST example is for classification, whereas MSE should be used for regression. This can be found in the Torch nn documentation.

Thank you.

I suspect returning vector in getIterator(mode) {...} is not work.
(specifically, variable 'load' in ListDataset cannot contain vector as target.

target = torch.LongTensor(1,10) or target = torch.LongTensor(10, 1)
(instead of original line,
target = torch.LongTensor{dataset.label[idx] + 1} )
make error.

Will you have a plan to enhance it near some day?
