maybeLee opened a new issue #20769: URL: https://github.com/apache/incubator-mxnet/issues/20769
## Description I was trying to follow the official documentation: https://mxnet.apache.org/versions/1.6/api/python/docs/tutorials/packages/onnx/super_resolution.html to import an ONNX model into MXNet but failed. ### Error Message ``` ValueError Traceback (most recent call last) <ipython-input-6-d9827b2914f4> in <module>() ----> 1 sym, arg, aux = onnx_mxnet.import_model(onnx_model_file) /usr/local/lib/python3.7/dist-packages/mxnet/contrib/onnx/onnx2mx/import_model.py in import_model(model_file) 57 # loads model file and returns ONNX protobuf object 58 model_proto = onnx.load_model(model_file) ---> 59 model_opset_version = max([x.version for x in model_proto.opset_import]) 60 sym, arg_params, aux_params = graph.from_onnx(model_proto.graph, opset_version=model_opset_version) 61 return sym, arg_params, aux_params ValueError: max() arg is an empty sequence ``` ## To Reproduce code to reproduce ``` from PIL import Image import numpy as np import mxnet as mx import mxnet.contrib.onnx as onnx_mxnet from mxnet.test_utils import download from matplotlib.pyplot import imshow img_url = 'https://s3.amazonaws.com/onnx-mxnet/examples/super_res_input.jpg' download(img_url, 'super_res_input.jpg') model_url = 'https://s3.amazonaws.com/onnx-mxnet/examples/super_resolution.onnx' onnx_model_file = download(model_url, 'super_resolution.onnx') sym, arg, aux = onnx_mxnet.import_model(onnx_model_file) ``` You can also access the reproducible script online https://colab.research.google.com/drive/10FuegzQA3iDusWSw4ofCMIi4tOLxg0Dd?usp=sharing Can you help fix this issue? -- This is an automated message from the Apache Git Service.
