Implementation of Laplacian Loss in Pytorch

Building Laplacian Pyramid using EXPAND operator. The PyrUp operator is implemented by torch.nn.functional.conv_transpose2d. The PyrDown operator is implemented by torch.nn.functional.conv2d using gaussian kernel.

laplacianloss-pytorch's Issues

cpu but not CUDA

hi there,

I loved this simple code, however it doesn't run on CUDA out of the box.
What's missing?

To test change: cuda = False to cuda = True

"RuntimeError: Expected all tensors to be on the same device, but found at least two devicesm cpu and cuda:0! (when checking argument for argument weight in method wrapper_thnn_conv2d_forward)"

I would provide pull, but as I'm new to cuda, this is a stretch....

Would appreciate hint!

License ?

Hello,
Can you specify the LICENSE file please ?
Thanks
