示例1: get_initializer
# 需要导入模块: import mxnet [as 别名]
# 或者: from mxnet import initializer [as 别名]
def get_initializer(args):
init_type = getattr(mx.initializer, args.config.get('train', 'initializer'))

if init_type is mx.initializer.Xavier:
return mx.initializer.Xavier(magnitude=init_scale, factor_type=args.config.get('train', 'factor_type'))
return init_type(init_scale) 示例2: set_params
# 需要导入模块: import mxnet [as 别名]
# 或者: from mxnet import initializer [as 别名]

"""Assigns parameter and aux state values.
Parameters
----------
arg_params : dict
Dictionary of name to `NDArray`.
aux_params : dict
Dictionary of name to `NDArray`.
allow_missing : bool
If ``True``, params could contain missing values, and the initializer will be
called to fill those missing params.
force_init : bool
If ``True``, will force re-initialize even if already initialized.
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.
Examples
--------
>>> # An example of setting module parameters.
>>> sym, arg_params, aux_params = mx.model.load_checkpoint(model_prefix, n_epoch_load)
>>> mod.set_params(arg_params=arg_params, aux_params=aux_params)
