caffe 的边训练边测试

个人认为需要改以下两个地方：训练文件中增加测试层

                                                        在solver.prototxt中设定迭代多少次进行测试

train_val.prototxt

###### test layer, ignore_label

layer {
  name: "accuracy"
  type: "Accuracy"
  bottom: "score"
  bottom: "label"
  top: "accuracy"
  accuracy_param{ ignore_label: 255 }
  include {
    phase: TEST
  }
}
