**Main aliases**

[`tf.reduce_any`](https://www.tensorflow.org/api_docs/python/tf/math/reduce_any)

<br />

    tf.math.reduce_any(
        input_tensor, axis=None, keepdims=False, name=None
    )

Reduces `input_tensor` along the dimensions given in `axis`.
Unless `keepdims` is true, the rank of the tensor is reduced by 1 for each
entry in `axis`. If `keepdims` is true, the reduced dimensions
are retained with length 1.

If `axis` is None, all dimensions are reduced, and a
tensor with a single element is returned.

#### For example:

    x = tf.constant([[True,  True], [False, False]])
    tf.reduce_any(x)  # True
    tf.reduce_any(x, 0)  # [True, True]
    tf.reduce_any(x, 1)  # [True, False]

| ## Args ||
|---|---|
| `input_tensor` | The boolean tensor to reduce. |
| `axis` | The dimensions to reduce. If `None` (the default), reduces all dimensions. Must be in the range `[-rank(input_tensor), rank(input_tensor))`. |
| `keepdims` | If true, retains reduced dimensions with length 1. |
| `name` | A name for the operation (optional). |
