title: Unknown blob input data to layer 0 in caffe
body: <p>I am getting following error while using my caffe prototxt:</p>
  
  <pre><code>F0329 17:37:40.771555 24587 insert_splits.cpp:35] Unknown blob input data to layer 0
  *** Check failure stack trace: ***
  </code></pre>
  
  <p>The first 2 layers in my caffe prototxt is given below:</p>
  
  <pre><code>layers {
    name: "data"
    type: IMAGE_DATA
    top: "data"
    top: "label"
    include {
      phase: TRAIN
    }
    image_data_param {
      source: "train2.txt"
      batch_size: 100
      new_height: 28
      new_width: 28
      is_color: false
    }
  }
  layers {
    name: "conv1"
    type: CONVOLUTION
    bottom: "data"
    top: "conv1"
    blobs_lr: 1
    blobs_lr: 3
    convolution_param {
      num_output: 8
      kernel_size: 9
      stride: 1
      weight_filler { type: "xavier" }
      bias_filler { type: "constant" }
    }
  }
  </code></pre>
  
  <p>What could be the possible reason for the same ?</p>
