Change the parameter of "patch" in data layer

[vccoderalex]

When I use the default setting 4 for the "patch", memory is not enough. I have to change it to 1. Then the training of encoder can run and finish.But some per-class-accuracy are zero while other are something like 0.9. Still keep patch be 1, now after training of encoder-decoder finish, I found all "per-class-accuracy" are zero. Would you please give me some information for that? Thanks!
