'Initializes parameters.
Parameters
initializer : Initializer
arg_params : dict
Defaults to ``None``. Existing parameters. This has higher priority
than `initializer`.
aux_params : dict
Defaults to ``None``. Existing auxiliary states. This has higher priority
than `initializer`.
allow_missing : bool
Allow missing values in `arg_params` and `aux_params` (if not ``None``).
In this case, missing values will be filled with `initializer`.
force_init : bool
Defaults to ``False``.
allow_extra : boolean, optional
Whether allow extra parameters that are not needed by symbol.
If this is True, no error will be thrown when arg_params or aux_params
contain extra parameters that is not needed by the executor.'
