Convert mxnet model to IR, name not found in symbol.list_arguments()

[ningningG]

Platform (like ubuntu 16.04/win10): win10

Python version: 3.6.6

Source framework with version (like Tensorflow 1.4.1 with GPU): mxnet 1.3.0

Destination framework with version (like CNTK 2.3 with GPU): tensorflow 1.10.0 with GPU

Running scripts: mmtoir -f mxnet -n sag_cor-symbol.json -w sag_cor-0500.params -d sag_cor_line --inputShape 1,256,256

When converting there are folowing warnings and errors

When add 'print('current_node.name : ', current_node.name)' in gen_IR in mxnetparser.py before 'if hasattr(self, "rename" + node_type):', only 'current_node.name : data' and 'current_node.name : label' is printed, can't parse other layers, why? Please help me

Hi @ningningG , could you provide your model file for us to debug?

[ningningG]

Thanks for your reply @namizzz , this is a UNet model I trained, not a pred_trained model download from the Internet. model path : https://drive.google.com/open?id=1f792k3-jmxzrxlQlCF9AXeOvv6065Tqa

@namizzz Do you have any update since then?

I have a model without lost layer, which is purely for inference, also have the same kind of issue.

    assert isinstance(input_arg[3], list)
AssertionError

I dont it is nessnary to include the lost layer in the model for conversion.

@kice I have the same problem with you.

@kice @WSCZou I have the same error as you both, did you have any progress?

@kice @WSCZou @not-william @hereandnowhan Not having the label name isn't an issue for the conversion. But for the assertion error, it's because you forgot to add the --inputShape argument for example, if your input shape is (batch, channels, h, w), you need to add : --inputShape channels,h,w to your command line
