    tf.compat.v1.glorot_uniform_initializer(
        seed=None,
        dtype=https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/dtypes#float32
    )

It draws samples from a uniform distribution within \[-limit, limit\]
where `limit` is `sqrt(6 / (fan_in + fan_out))`
where `fan_in` is the number of input units in the weight tensor
and `fan_out` is the number of output units in the weight tensor.

| ## Args ||
|---|---|
| `seed` | A Python integer. Used to create random seeds. See [`tf.compat.v1.set_random_seed`](https://www.tensorflow.org/versions/r2.14/api_docs/python/tf/compat/v1/set_random_seed) for behavior. |
| `dtype` | Default data type, used if no `dtype` argument is provided when calling the initializer. Only floating point types are supported. |

## Methods

### `from_config`

[View source](https://github.com/tensorflow/tensorflow/blob/v2.14.0/tensorflow/python/ops/init_ops.py#L75-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. It will typically be the output of `get_config`. |

<br />

<br />

<br />

<br />

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

<br />

### `get_config`

[View source](https://github.com/tensorflow/tensorflow/blob/v2.14.0/tensorflow/python/ops/init_ops.py#L1623-L1624)

    get_config()

Returns the configuration of the initializer as a JSON-serializable dict.

<br />

<br />

<br />

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

<br />

### `__call__`

[View source](https://github.com/tensorflow/tensorflow/blob/v2.14.0/tensorflow/python/ops/init_ops.py#L858-L883)

    __call__(
        shape, dtype=None, partition_info=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. If not provided use the initializer dtype. |
| `partition_info` | Optional information about the possible partitioning of a tensor. |
