tf.compat.v1.keras.initializers.Constant Initializer that generates tensors with constant values.  View aliases  Compat aliases for migration 
See Migration guide for more details. tf.compat.v1.constant_initializer, tf.compat.v1.initializers.constant, tf.compat.v1.keras.initializers.constant  
tf.compat.v1.keras.initializers.Constant(
    value=0, dtype=tf.dtypes.float32, verify_shape=False
)
 The resulting tensor is populated with values of type dtype, as specified by arguments value following the desired shape of the new tensor (see examples below). The argument value can be a constant value, or a list of values of type dtype. If value is a list, then the length of the list must be less than or equal to the number of elements implied by the desired shape of the tensor. In the case where the total number of elements in value is less than the number of elements required by the tensor shape, the last element in value will be used to fill the remaining entries. If the total number of elements in value is greater than the number of elements required by the tensor shape, the initializer will raise a ValueError.
 


 Args
  value   A Python scalar, list or tuple of values, or a N-dimensional numpy array. All elements of the initialized variable will be set to the corresponding value in the value argument.  
  dtype   Default data type, used if no dtype argument is provided when calling the initializer.  
  verify_shape   Boolean that enables verification of the shape of value. If True, the initializer will throw an error if the shape of value is not compatible with the shape of the initialized tensor.   
 


 Raises
  TypeError   If the input value is not one of the expected types.    Examples: The following example can be rewritten using a numpy.ndarray instead of the value list, even reshaped, as shown in the two commented lines below the value list initialization. 
value = [0, 1, 2, 3, 4, 5, 6, 7]
init = tf.compat.v1.constant_initializer(value)
# fitting shape
with tf.compat.v1.Session():
  x = tf.compat.v1.get_variable('x', shape=[2, 4], initializer=init)
  x.initializer.run()
  print(x.eval())

# Larger shape

  y = tf.compat.v1.get_variable('y', shape=[3, 4], initializer=init)
  y.initializer.run()
  print(y.eval())

 Methods from_config View source 
@classmethod
from_config(
    config
)
 Instantiates an initializer from a configuration dictionary. Example: initializer = RandomUniform(-1, 1)
config = initializer.get_config()
initializer = RandomUniform.from_config(config)

 


 Args
  config   A Python dictionary. It will typically be the output of get_config.   
 


 Returns   An Initializer instance.  
 get_config View source 
get_config()
 Returns the configuration of the initializer as a JSON-serializable dict.
 


 Returns   A JSON-serializable Python dict.  
 __call__ View source 
__call__(
    shape, dtype=None, partition_info=None, verify_shape=None
)
 Returns a tensor object initialized as specified by the initializer.
 


 Args
  shape   Shape of the tensor.  
  dtype   Optional dtype of the tensor. If not provided use the initializer dtype.  
  partition_info   Optional information about the possible partitioning of a tensor.
