> right, I don't think it's exposed in the frontend. lr_mult should be set
on a variable such as the weight of fullyconnected.
ok, since i can't find any official example for doing this, now i do it by
myself:
1, is the following code right?
```
_weight = mx.symbol.Variable("fc1_weight", lr_mult=10, )
fc1 = mx.sym.FullyConnected(data=fc0, num_hidden=num_classes, name='fc1')
```
2, do i need to set the lr_mult for optimizer at the same time to make it
work? or just set one of them is enough? some post said it also need to set
lr_mult for the optimizer [post1](https://discuss.gluon.ai/t/topic/6002/12)
