QueensGambit edited a comment on issue #15337: Current MXNet-Dev master breaks loading of certain models URL: https://github.com/apache/incubator-mxnet/issues/15337#issuecomment-513383904 I think, I know why the loading fails, thank you for help @roywei. It's because I ported the training code from Gluon to MXNet for this model. The reason for this was that I experienced long delays during training due to `MXNET_CUDNN_AUTOTUNE_DEFAULT` calls: * https://github.com/apache/incubator-mxnet/issues/15529 Apparently in MXNet version 1.4.1 the code above works successfully and ignores the missing label information whereas version 1.5.0 blocks it, which is a behaviour I appreciate. Using this code I'm able to successfully load the model both in version MXNet 1.4.1 and MXNet 1.5.0: ```python model_arch_path = 'model-1.19246-0.603-symbol.json' model_params_path = 'model-1.19246-0.603-0223.params' ctx = mx.cpu() symbol = mx.sym.load(model_arch_path) inputs = mx.sym.var('data', dtype='float32') value_out = symbol.get_internals()['value_tanh0_output'] policy_out = symbol.get_internals()['flatten0_output'] sym = mx.symbol.Group([value_out, policy_out]) net = mx.gluon.SymbolBlock(sym, inputs) net.collect_params().load(model_params_path, ctx) ``` Consequently, this issue can be closed.
