pdx1989 opened a new issue #14957: [Bug] ValueError: There are multiple outputs with name "resnetv1b_layers4_conv0_fwd_output"
URL: https://github.com/apache/incubator-mxnet/issues/14957
 
 
   Minimum reproducible example:
   import gluoncv
   import mxnet as mx
   
   data = mx.sym.var(name="data")
   net = gluoncv.model_zoo.mask_rcnn_resnet50_v1b_coco(pretrained=False)
   net.initialize()
   sym = net(data)
   sym_block = mx.gluon.nn.SymbolBlock(sym, [data])
   
   Error:
   Traceback (most recent call last):
     File "case.py", line 8, in <module>
       sym_block = mx.gluon.nn.SymbolBlock(sym, [data])
     File "/newhome/daoxin/py3-env/lib/python3.5/site-packages/mxnet/gluon/block.py", line 1050, in __init__
       for j in i.get_internals():
     File "/newhome/daoxin/py3-env/lib/python3.5/site-packages/mxnet/symbol/symbol.py", line 93, in <genexpr>
       return (self[i] for i in self.list_outputs())
     File "/newhome/daoxin/py3-env/lib/python3.5/site-packages/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 "resnetv1b_layers4_conv0_fwd_output"
   
   Version:
   gluoncv 0.4.0
   mxnet 1.4.0
   
   Could anyone help me? Thank you!
