   The problem is in the sample code. Since HybridSequentialRNNCell is a container block, you need to use its name_scope if you intend to properly export it as a symbol.
   ```
   class MyBlock(mx.gluon.HybridBlock):
       def __init__(self):
           super().__init__()
           with self.name_scope():
               self.lstm = mx.gluon.rnn.HybridSequentialRNNCell()
               with self.lstm.name_scope():
                   for layer in range(3):
                       self.lstm.add(mx.gluon.rnn.LSTMCell(hidden_size=20))
   
       def hybrid_forward(self, F, seq):
           outputs, state = self.lstm.unroll(inputs=seq, length=10, layout="NTC", merge_outputs=True)
           return outputs
   ```
