I'm trying from several weeks to do regression with image data, there is a single label associated with my each image in the dataset and I want to train a caffe model on this dataset, I followed many links of doing regression with image data from Github and didn't succeed yet, is there anybody who can assist me, so far I've created lmdb database of my data and when I pull it to the network with Eucledean distance I get an error when I make some modifications, get some other error then
