i set lr__mult attr of symbol, and used optimizer and Module, it don't work.that because i don't give sym params when i creat optimizer.now solved it.

[Light--]

now solved it.

@lly8752
could you please share how to solve it? some example code?
and
what do you mean by i don't give sym params when i creat optimizer? i create the opt using:

opt = optimizer.SGD(learning_rate=base_lr, momentum=base_mom, wd=base_wd, rescale_grad=_rescale)

which doesn't need the sym as input.
