mxnet symbol, for metric, how to get labels and preds from netowrk, from variable names or symbol names?

In my symbol neural structure, I use mx,symbol.Group(loss1, loss2), when I change the metric loss1, loss2 also has been influenced. I do not know the reason. Any advice will be appreciated. Thank you very much.
