Ishitori commented on issue #13616: SymbolBlock doesn't print anything URL: https://github.com/apache/incubator-mxnet/issues/13616#issuecomment-450225823 I confirm this behavior, and here is the minimal reproducible example: ``` import mxnet as mx from mxnet.gluon.nn import HybridSequential, Dense model = HybridSequential() model.add(Dense(units=10)) model.initialize() model.hybridize() model(mx.random.uniform(shape=(10, 100))) model.export("./model") block = mx.gluon.nn.SymbolBlock.imports('model-symbol.json', ['data'], 'model-0000.params') print(block) ``` Result that is printed on the screen looks like: ``` SymbolBlock( ) ``` Funny that both pure Gluon and pure Symbol models are still printing something. For Gluon model I would receive expected output: ``` HybridSequential( (0): Dense(100 -> 10, linear) ) ``` For same model using Symbolic API I receive only the name of the last layer (not very useful, but still it is something): ``` <Symbol fc1> ``` I would mark this issue as a bug.
