## Minimum reproducible example
Using the `ONNX` model from the tutorial :
`https://s3.amazonaws.com/onnx-mxnet/examples/super_resolution.onnx`
```
#!/usr/bin/env python
import torch
import mxnet.contrib.onnx as onnx_mxnet
_, _, _ = onnx_mxnet.import_model("super_resolution.onnx")
```
## Steps to reproduce
(Paste the commands you ran that produced the error.)
1. `./import_onnx.py`
## What have you tried to solve it?
1. I tried using version 1.2.0 from `pip install mxnet`
2. Then I installed version 1.3.0 from `pip install mxnet --pre`
3. Tried using `import_to_gluon`
