Deconvolution in Caffe - blob size exceeds INT_MAX

https://stackoverflow.com/questions/43735788/deconvolution-in-caffe-blob-size-exceeds-int-max

It's based on a network from a paper that claims to use Caffe for the implementation. Here's the topology: To the best of my ability, I've tried to recreate the model. The authors use the term "upconv" which is a combination of 2x2 unpooling followed by 5x5 convolution. I've taken this to mean a deconvolutional layer with stride 2 and kernel ...
