* @brief Returns the random permutation of integers from 0 to n-1. \n
* @par Inputs:
* Inputs include:
* @li n: A 1-dimensional int64 tensor, shape must be [1].
* @li seed: A 1-dimensional int64 tensor, shape must be [1]. If seed is set to be -1,
* and offset is set to be 0, the random number generator is seeded by a random seed.
* Otherwise, it is seeded by the given seed.
* @li offset: A 1-dimensional int64 tensor, shape must be [1]. To avoid seed collision. \n
* @par Attributes:
* @li layout: An optional int. Defaults to 0.
* @li dtype: An optional type, used to specify the data type of output y. Defaults to int64. \n
* @par Outputs:
* @li y: A mutable tensor, shape is [n]. Must be one of the following types:
* float16, float32, double, int8, uint8, int16, int32, int64, bfloat16. \n
* @attention Constraints:
* The implementation for Randperm on Ascend uses AICPU, with bad performance.
* @par Third-party framework compatibility
* Compatible with Pytorch Randperm operator.
