feevos opened a new issue #10101: gluon feature request: proper registration/initialization of layers inside a list for custom (Hybrid)Blocks
URL: https://github.com/apache/incubator-mxnet/issues/10101
 
 
   Dear all, it would be very useful if one could add NN layers of a gluon custom model inside a list, similar to ```torch.nn.ModuleList```, something like: 
   
   ```Python
   
   class CustomNet(HybridBlock):
   
       def __init__(self,**kwards):
           HybridBlock.__init__(self,**kwards)
           with self.name_scope():
              layers_list = []
              for i in range(5):
                  layers_list += [gluon.nn.Conv2D( SomeArguments )]
   
   
       def hybrid_forward(self,F,_x):
            # Some manipulation of layers_list elements
            out = ... 
    
           return out
   ```
   I can think of many use cases, but one important one is indexing for neuroevolution problems, i.e. using a variable architecture of a specified set of layers. 
   
   Thank you very much for the great work you put into gluon/mxnet.
