How to add a custom python loss layer?

[ABHISHEK SETHI]

I added a custom loss layer and made changes in the prototxt file as folows but I am getting the following error.

## modified loss layer

layers {

  type: PYTHON

  name: 'loss'

  bottom: "ip2"

  bottom: "label"

  top: "loss"

  python_param {

    module: 'loss_layers'

    layer: 'EuclideanLossLayer'

  }

  loss_weight: 1

}

ERROR:

Error parsing text-format caffe.NetParameter: 294:3: Unknown enumeration value of "PYTHON" for field "type"

It looks like you're using old syntax. Modern prototxt should look like this instead:

layer {
  type: "Python"
  name: "loss"
  ...
}

Note the singular "layer" and "Python" in double quotes with only first letter capitalized.
