kuonangzhe opened a new issue #12486: gluon.nn.SymbolBlock.imports Error
URL: https://github.com/apache/incubator-mxnet/issues/12486
 
 
   We use mxnet 1.3.0 on Ubuntu 16.04, python3.5, with model loading method SymbolBlock.imports. Then get error as follows:
   
   ```
   [20:52:20] src/nnvm/legacy_json_util.cc:209: Loading symbol saved by previous version v1.2.1. Attempting to upgrade...
   [20:52:20] src/nnvm/legacy_json_util.cc:217: Symbol successfully upgraded!
   Traceback (most recent call last):

       ret = SymbolBlock(sym, inputs)
     File "/home/name/mxnet-1.3/python/mxnet/gluon/block.py", line 1051, in __init__
       for j in i.get_internals():

       return (self[i] for i in self.list_outputs())
     File "/home/name/mxnet-1.3/python/mxnet/symbol/symbol.py", line 517, in __getitem__
       raise ValueError('There are multiple outputs with name \"%s\"' % index)
   ValueError: There are multiple outputs with name "resmodel0_relu0_fwd_output"
   ```
   
   While we tried with mxnet 1.2.1 and the program ran well. There might be some problems in the function but we are not sure. Are there any suggestions?
