Export ONNX model

[soyebn]

I am trying to export MNXet Model to ONNX by doing the following at the end of the script, Single-Path-One-Shot-NAS-MXNet/oneshot_nas_network.py

sym_file_name = "./symbols/ShuffleNas_fixArch-symbol.json"
param_file_name = './symbols/ShuffleNas_fixArch-0000.params'
onnx_file_name = "./supernet_random.onnx"
input_shape = (1,3,224,224)
converted_model_path = onnx_mxnet.export_model(sym_file_name, param_file_name, [input_shape], np.float32, onnx_file_name, verbose=True)

---

I am getting the following error,
AttributeError: ('Reshape: Shape value not supported in ONNX', -4)

output_shape_list is [0, -4, 2, -1, -2]. And MxNet/ONNX does not support the following values.
not_supported_shape = [-2, -3, -4]

What am I doing wrong? Or ONNX export is not supported for this model?

Did you ever fix this? I am in the exact same situation.
