tf.keras.ops.logsumexp

Computes the logarithm of sum of exponentials of elements in a tensor.

tf.keras.ops.logsumexp(
    x, axis=None, keepdims=False
)

Args
`x`	Input tensor.
`axis`	An integer or a tuple of integers specifying the axis/axes along which to compute the sum. If `None`, the sum is computed over all elements. Defaults to`None`.
`keepdims`	A boolean indicating whether to keep the dimensions of the input tensor when computing the sum. Defaults to`False`.

Returns
A tensor containing the logarithm of the sum of exponentials of elements in `x`.

x = keras.ops.convert_to_tensor([1., 2., 3.])
logsumexp(x)
