### Used in the notebooks

| Used in the tutorials |
|---|
| - [Scalable model compression](https://www.tensorflow.org/tutorials/optimization/compression) |

#### Examples:

    # Standalone usage:
    initializer = Zeros()
    values = initializer(shape=(2, 2))

    # Usage in a Keras layer:
    initializer = Zeros()
    layer = Dense(units=3, kernel_initializer=initializer)

## Methods

### `clone`

[View source](https://github.com/keras-team/keras/tree/v3.15.1/keras/src/initializers/initializer.py#L96-L97)

    clone()

### `from_config`

[View source](https://github.com/keras-team/keras/tree/v3.15.1/keras/src/initializers/initializer.py#L76-L94)

    @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)

<br />

<br />

<br />

| Args ||
|---|---|
| `config` | A Python dictionary, the output of `get_config()`. |

<br />

<br />

<br />

<br />

| Returns ||
|---|---|
| An `Initializer` instance. ||

<br />

### `get_config`

[View source](https://github.com/keras-team/keras/tree/v3.15.1/keras/src/initializers/initializer.py#L68-L74)

    get_config()

Returns the initializer's configuration as a JSON-serializable dict.

<br />

<br />

<br />

| Returns ||
|---|---|
| A JSON-serializable Python dict. ||

<br />

### `__call__`

[View source](https://github.com/keras-team/keras/tree/v3.15.1/keras/src/initializers/constant_initializers.py#L64-L75)

    __call__(
        shape, dtype=None
    )

Returns a tensor object initialized as specified by the initializer.

<br />

<br />

<br />

| Args ||
|---|---|
| `shape` | Shape of the tensor. |
| `dtype` | Optional dtype of the tensor. Only numeric or boolean dtypes are supported. If not specified, [`keras.backend.floatx()`](https://www.tensorflow.org/api_docs/python/tf/keras/backend/floatx) is used, which default to `float32` unless you configured it otherwise (via [`keras.backend.set_floatx(float_dtype)`](https://www.tensorflow.org/api_docs/python/tf/keras/backend/set_floatx)). |
