*@brief Converts each string in the input Tensor to the specified numeric type . \n

*@par Inputs:
*Inputs include:

*@par Attributes:
*out_type: The numeric type to interpret each string in string_tensor as . \n

*@par Outputs:
*y: A Tensor. Has the same type as x . \n

*@attention Constraints:
*The implementation for StringToNumber on Ascend uses AICPU, with bad performance. \n

*@par Third-party framework compatibility
*@li compatible with tensorflow StringToNumber operator.
