Calcula la permutación inversa de un tensor.
Esta operación calcula la inversa de una permutación de índice. Toma un tensor entero 1-D `x`, que representa los índices de una matriz de base cero, e intercambia cada valor con su posición de índice. En otras palabras, para un tensor de salida "y" y un tensor de entrada "x", esta operación calcula lo siguiente:
`y[x[i]] = i para i en [0, 1, ..., len(x) - 1]`
Los valores deben incluir 0. No puede haber valores duplicados ni valores negativos.
Por ejemplo:
# tensor `x` is [3, 4, 0, 2, 1]
invert_permutation(x) ==> [2, 4, 3, 0, 1]

It takes a 1-D\ninteger tensor \\`x\\`, which represents the indices of a zero-based array, and\nswaps each value with its index position. In other words, for an output tensor\n\\`y\\` and an input tensor \\`x\\`, this operation computes the following:\n\n\n\\`y\\[x\\[i\\]\\] = i for i in \\[0, 1, ..., len(x) - 1\\]\\`\n\n\nThe values must include 0. There can be no duplicate values or negative values.\n\n\nFor example: \n\n # tensor `x` is [3, 4, 0, 2, 1]\n invert_permutation(x) ==\u003e [2, 4, 3, 0, 1]\n \n\u003cbr /\u003e\n\n\u003cbr
