Message type "caffe.LayerParameter" has no field named "threshold".

i want use Threshold Layer with t=0.5 but when i run caffe this error occur :

[libprotobuf ERROR C:\Users\guillaume\work\caffe-builder\build_v140_x64\packages\protobuf\protobuf_download-prefix\src\protobuf_download\src\google\protobuf\text_format.cc:298] Error parsing text-format caffe.NetParameter: 161:12: Message type "caffe.LayerParameter" has no field named "threshold".

my defined network :

layer {
  name: "Sigmoid1"
  type: "Sigmoid"
  bottom: "ip2"
  top: "ip3"
}
layer {
  name: "Threshold1"
  type: "Threshold"
  threshold: 0.5
  bottom: "ip3"
  top: "ip4"
}

why this error occur?

As any layer, the Threshold Layer does not input any parameters directly. Instead, it takes a parameter structure, within which all the parameters are defined. That is, just like Convolution layer has convolution_param and InnerProduct has inner_product_param, so the Threshold has threshold_param. So you should do something like that instead:

layer {
  name: "..."
  type: "Threshold"
  bottom: "..."
  top: "..."
  threshold_param {
    threshold: <value>
  }
}
