run_model() missing 1 required positional argument: 'inputs'

[hauhsu]

I was trying to run the example in README, but there is an error:

Traceback (most recent call last):
  File "./plaidml-test.py", line 18, in <module>
    output = onnx_plaidml.backend.run_model(model, [data])
  File "/home/hsu.hau/.virtualenvs/ml/lib/python3.5/site-packages/onnx_plaidml/backend.py", line 166, in run_model
    return super(PlaidMLBackend, cls).run_model(model, device=device, **kwargs)
TypeError: run_model() missing 1 required positional argument: 'inputs'

And I have to modify the code onnx_plaidml/backend.py to avoid this error:

166c166
<         return super(PlaidMLBackend, cls).run_model(model, inputs, device=device, **kwargs)
---
>         return super(PlaidMLBackend, cls).run_model(model, device=device, **kwargs)

Is that a bug or I did something wrong?
Thanks!
