onnx_import.py : AttributeError: 'NoneType' object has no attribute 'output_shapes' about ell HOT 2 CLOSED

Hi,

I spent a little time on the issue and here is what I learned.
It seems that the Onnx library and format has evolved a lot since this ELL project has been updated.
My understanding is that the Onnx to ELL converter scripts would need some update to support
the current opset. On the lastest python updates, the scripts produce a Onnx file that uses opset 9 while it appears the Onnx to ELL was design to handle opset 6.
I did try "torch.onnx.export(self, dummy_input, name, verbose=True, opset_version=7)" but
still ran into issue. Sadly, the latest Onnx package does not support opset 6 or lower.
From there, it could be possible to downgrade python package, ... ...
or the Onnx to ELL could be updated. I did some progress on that but stopped after
figuring out that the amount of work required was bigger then what I could invest in this project.

If you plan to invest time in this project, be aware of this situation.

This is fixed by this commt.
