tf.keras.backend.var

Variance of a tensor, alongside the specified axis.

Compat aliases for migration

tf.compat.v1.keras.backend.var, `tf.compat.v2.keras.backend.var`

tf.keras.backend.var(
    x, axis=None, keepdims=False
)

Arguments
`x`	A tensor or variable.
`axis`	An integer, the axis to compute the variance.
`keepdims`	A boolean, whether to keep the dimensions or not. If `keepdims` is `False`, the rank of the tensor is reduced by 1. If `keepdims` is `True`, the reduced dimension is retained with length 1.

Returns
A tensor with the variance of elements of `x`.
