[feixiaoyu2223]

When i run the 'train_id_net_res_2stream ',there is an error shows: "The subscript index must be a positive integer type or a logical type. Wrong in train_id_net_res_2stream (line 13) net.params(net.getParamIndex('fc751f')).learningRate = 0.01;" My enviroment is win10 +matlab2016. Can you tell me where is the problem?Thank you.

Hi @feixiaoyu2223 Could you print

net.getParamIndex('fc751f')

It should be a positive number.

When i add this commend ,It shows: ans =

NaN The subscript index must be a positive integer type or a logical type. Wrong in train_id_net_res_2stream (line 13) net.params(net.getParamIndex('fc751f')).learningRate = 0.01;

The code seems not find the weight fc751f, which is the weight for the last classification layer.

Could you try

net = resnet52_market()
net.getParamIndex('fc751f')

It shows ans =
