'Gets parameters, those are potentially copies of the the actual parameters used
to do computation on the device.
Returns
``(arg_params, aux_params)``
A pair of dictionaries each mapping parameter names to NDArray values.
Examples
>>> # An example of getting module parameters.
>>> print mod.get_params()

\'fc3_bias\': <NDArray 10 @cpu(0)>, \'fc3_weight\': <NDArray 10x64 @cpu(0)>,
\'fc2_bias\': <NDArray 64 @cpu(0)>, \'fc1_bias\': <NDArray 128 @cpu(0)>}, {})'
