Implementation of the VGG Architecture usable in nVidia DIGITS

Since I could not find any network descriptions that just worked out of the box in DIGITS, here is what I use. The following can just be copied to the custom network text box and should work.

name: "VGG_ILSVRC_16_layers"
# Input
layer {
  name: "data"
  type: "Data"
  top: "data"
  top: "label"
  include {
    stage: "train"
  }
 transform_param {
    mirror: false
 }
 data_param {
    batch_size: 32
  }
}

layer {
  name: "data"
  type: "Data"
  top: "data"
  top: "label"
  include {
    stage: "val"
  }
 transform_param {
    mirror: false
 }
 data_param {
    batch_size: 32
  }
}
