[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 =
