*@brief Computes the trignometric inverse tangent of x element-wise.
* The atan operation returns the inverse of tan, such that if y = tan(x) then, x = atan(y).
*
*@par Inputs:
* x: An ND or 5HD tensor. support 1D ~ 8D. Must be one of the following types:
* int8, int16, int32, int64, uint8, bool, float32, float16, float64, bfloat16.
*
*@par Outputs:
* y: A tensor. Must be one of the following types:
* float32, float16, float64, bfloat16.
* The output of atan will lie within the invertible range of tan, i.e (-pi/2, pi/2).
*
*@par Third-party framework compatibility
*Compatible with the TensorFlow operator Atan.
