Error when running hello_query_device.py

[Tenn__Hian-Kun]

Hi,

I've installed the OpenVINO R2 and started to try some the samples.

For the C++ version of "hello query device", everything was okay.

But when I tried to run the Python sample, it returned the following error message:

Traceback (most recent call last):
  File "hello_query_device.py", line 35, in <module>
    sys.exit(main() or 0)
  File "hello_query_device.py", line 30, in main
    cfg_val = ie.get_config(device, cfg)
  File "ie_api.pyx", line 124, in openvino.inference_engine.ie_api.IECore.get_config
TypeError: Failed to convert parameter to Python representation!

How could I fix it?

Dear Tenn, Hian-Kun,

You are correct. I reproduced the same bug on OpenVino 2019R2.

I will file a bug on your behalf. 

Sorry for the trouble !

Thanks,
