tf.math.invert_permutation( x, name=None )
This operation computes the inverse of an index permutation. It takes a 1-D integer tensor
x, which represents the indices of a zero-based array, and swaps each value with its index position. In other words, for an output tensor
y and an input tensor
x, this operation computes the following:
y[x[i]] = i for i in [0, 1, ..., len(x) - 1]
The values must include 0. There can be no duplicate values or negative values.
# tensor `x` is [3, 4, 0, 2, 1] invert_permutation(x) ==> [2, 4, 3, 0, 1]
