   ## Description

   This has been observer in the kaggle Notebook as well as Google Colab (!pip install mxnet-cu101) was done.
   
   ### Error Message

        92     batch_end_callback=batchEndCBs,
       ---> 93     epoch_end_callback=epochEndCBs)
        94 
        95 
   
        /usr/local/lib/python3.6/dist-packages/mxnet/model.py in fit(self, X, y, eval_data, eval_metric, epoch_end_callback, 
       batch_end_callback, kvstore, logger, work_load_list, monitor, eval_end_callback, eval_batch_end_callback)
       894                                    **(self.kwargs))
       895         elif isinstance(self.optimizer, opt.Optimizer):
       --> 896             if not optimizer.idx2name:
       897                 optimizer.idx2name = param_idx2name.copy()
       898             optimizer = self.optimizer
   
       UnboundLocalError: local variable 'optimizer' referenced before assignment
   
   ## To Reproduce

   ## Steps taken 
   1. I have run the program in my local system which has Mxnet built from source. I get an different error ( related to batch size ) which I believe is different from the above one
