Network finetuning - fix auxiliary params

Hi,

I have a pretrained network and I am fine tuning it. I want to fix some of the weights of the network and modify the rest. I can specify the argument names that are to remain fixed via fixed_param_names(see below) but the auxiliary parameters(such as in batch norm) cannot be provided as arguments in fixed_param_names. Is it possible to fix the auxilary parameters? Please help.

class mxnet.module.Module(symbol, data_names=('data', ), label_names=('softmax_label', ), logger=, context=cpu(0), work_load_list=None, fixed_param_names=None, state_names=None, group2ctxs=None, compression_params=None)
