+### `tf.invert_permutation(x, name=None)` {#invert_permutation}
+
+Computes the inverse permutation of a tensor.
+
+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.
+
+For example:
+
+```prettyprint
+# tensor `x` is [3, 4, 0, 2, 1]
+invert_permutation(x) ==> [2, 4, 3, 0, 1]
+```
+
+##### Args:
+
+
+*  <b>`x`</b>: A `Tensor` of type `int32`. 1-D.
+*  <b>`name`</b>: A name for the operation (optional).
+
+##### Returns:
+
+  A `Tensor` of type `int32`. 1-D.
