How can I use learningRates option in SGD?

[erogol]

I try to give a vector of lrs per layer but it does not work. Here is my code;

     local learningRates = {}
     local params, gradParams = model:parameters()
     print(params[1]:size())
     for i=1, #params do
       learningRates[i] =  opt.LR
     end
     print("setting LR")
     learningRates[#params] = opt.topLayerLR
    --  print(learningRates)
     learningRates = torch.Tensor(learningRates):reshape(#params,1)
ocal params, gradParams = model:parameters()
     print(params[1]:size())
     for i=1, #params do
       learningRates[i] =  opt.LR
     end
     print("setting LR")
     learningRates[#params] = opt.topLayerLR
    --  print(learningRates)
     learningRates = torch.Tensor(learningRates):reshape(#params,1)

Could you help me how to use learningRates in a propoer way?
