示例1: _AddParam
# 需要導入模塊: import tensorflow [as 別名]
# 或者: from tensorflow import DataType [as 別名]
def _AddParam(self,
shape,
dtype,
name,
initializer=None,
return_average=False):
"""Add a model parameter w.r.t. we expect to compute gradients.
_AddParam creates both regular parameters (usually for training) and
averaged nodes (usually for inference). It returns one or the other based
on the 'return_average' arg.
Args:
shape: int list, tensor shape of the parameter to create
dtype: tf.DataType, data type of the parameter
name: string, name of the parameter in the TF graph
initializer: optional initializer for the paramter
return_average: if False, return parameter otherwise return moving average
Returns:
parameter or averaged parameter
