xmfbit opened a new issue #11278: global name 'multiply' is not defined when using LBSGD
URL: https://github.com/apache/incubator-mxnet/issues/11278
 
 
   When I use LBSGD, the error occurs that reminds me
   ```
      File "/home/me/anaconda/lib/python2.7/site-packages/mxnet/optimizer.py", line 758, in _l2norm
       norm = multiply(v, v).asnumpy().sum()
   NameError: global name 'multiply' is not defined
   ```
   I add this in the `optimizer.py` manually and have solved the problem. So is this a bug existing in MXNet?
   ```
   from .ndarray import multiply
   ```
   And I want to know whether the LBSGD optimizer is done or not in MXNet. Because I see this in https://github.com/apache/incubator-mxnet/blob/master/python/mxnet/optimizer.py#L734:
   ```
       def _get_lbmult(self, nup):
           """Returns lr scaling factor for large batch according to warmup schedule
           (to be implemented)
   ```
