you can't label a fc network with biases

[yue-SJTU]

maybe I'm wrong,but I found you may not mark the network with biases,such as fc(x, config, θ,"label"),which would arise error

When you provide θ, you do need "label" because the deep neural network is uniquely identified by θ.

"label" is useful when you build a neural network by specifying weights and biases implicitly. For example

y1 = fc(x, config) 
y2 = fc(x, config)

y1 and y2 are outputs of the same DNN.

y1 = fc(x, config,"label1") 
y2 = fc(x, config,"label2")

y1 and y2 are outputs of two different DNNs.
