Initializer that generates tensors initialized to 1.
Inherits From: ones_initializer
, Initializer
Also available via the shortcut function tf.keras.initializers.ones
.
Examples:
# Standalone usage:
initializer = tf.keras.initializers.Ones()
values = initializer(shape=(2, 2))
# Usage in a Keras layer:
initializer = tf.keras.initializers.Ones()
layer = tf.keras.layers.Dense(3, kernel_initializer=initializer)
Methods
from_config
@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
get_config()
Returns the configuration of the initializer as a JSON-serializable dict.
Returns | |
---|---|
A JSON-serializable Python dict. |
__call__
__call__(
shape, dtype=None, **kwargs
)
Returns a tensor object initialized as specified by the initializer.
Args | |
---|---|
shape
|
Shape of the tensor. |
dtype
|
Optional dtype of the tensor. Only numeric or boolean dtypes are
supported. If not specified, tf.keras.backend.floatx() is used,
which default to float32 unless you configured it otherwise
(via tf.keras.backend.set_floatx(float_dtype) ).
|
**kwargs
|
Additional keyword arguments. |
