lostella commented on issue #12783: Name conflict when serializing HybridSequentialRNNCell URL: https://github.com/apache/incubator-mxnet/issues/12783#issuecomment-428921900 I simplified the MWE: https://gist.github.com/lostella/9a790fd89726c1741a1fcf4194a5dac6 It seems like it's ultimately an LSTMCell problem. ``` import mxnet as mx class MyBlock(mx.gluon.HybridBlock): def __init__(self): super().__init__() with self.name_scope(): self.lstmcell = mx.gluon.rnn.LSTMCell(hidden_size=20) def hybrid_forward(self, F, seq): outputs, state = self.lstmcell.unroll(inputs=seq, length=10, layout="NTC", merge_outputs=True) return outputs block = MyBlock() block.initialize() block.hybridize() input = mx.nd.random_normal(shape=(32, 10, 5)) output = block(input) block.export(path="./model", epoch=0) symbol = mx.gluon.SymbolBlock.imports( symbol_file="./model-symbol.json", input_names=[f"data"], param_file="./model-0000.params", ctx=mx.Context.default_ctx ) ```
