Only scalar values are allowed. The constant value provided must be convertible to the dtype requested when calling the initializer.
Examples:
# Standalone usage:
initializer = Constant(10.)
values = initializer(shape=(2, 2))
# Usage in a Keras layer:
initializer = Constant(10.)
layer = Dense(3, kernel_initializer=initializer)
| Args | |
|---|---|
| value | A Python scalar. |
Methods
clone
clone()
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, the output of get_config(). |
| Returns |
|---|
| An Initializer instance. |
get_config
get_config()
Returns the initializer's configuration as a JSON-serializable dict.
| Returns |
|---|
| A JSON-serializable Python dict. |
__call__
__call__(
shape, dtype=None
)
Returns a tensor object initialized as specified by the initializer.
| Args | |
|---|---|
| shape | Shape of the tensor. |
| dtype | Optional dtype of the tensor. |
