Slice layer in caffe

[Dzung Nguyen]

I defined the following slice layer, where I want to split Nx6xHxW into 2 Nx3xHxW blobs

layer {
  name: "slice_pair"
  type: "Slice"
  bottom: "pair_data"
  top: "data"
  top: "data_p"
  slice_param {
    axis: 1
    slice_point: 3
  }
}

However when I run the training, caffe splits into two same size blobs

I1102 19:38:42.767278 30896 data_layer.cpp:44] output data size: 1,6,256,256

How do I fix this problem?

Hi,

try to change "axis" to "slice_dim":

layer {
  name: "slice_pair"
  type: "Slice"
  bottom: "pair_data"
  top: "data"
  top: "data_p"
  slice_param {

    slice_dim: 1
    slice_point: 3
  }
}

Cheers
Nicolai

Hi,

can you explain what's the difference between "slice_dim" and "axis"?

thanks a lot!

by the way,I have find this(https://groups.google.com/forum/#!topic/caffe-users/9SrQ0S2g8NM),but I dont understand it...
