This version of the operator has been available since version 1 of domain


Select elements of the input tensor based on the indices passed.

The indices are applied to the last axes of the tensor.


  • X (heterogeneous) - T: Data to be selected

  • Y (heterogeneous) - tensor(int64): The indices, based on 0 as the first index of any dimension.


  • Z (heterogeneous) - T: Selected output data as an array

Type Constraints

  • T in ( tensor(double), tensor(float), tensor(int32), tensor(int64), tensor(string) ): The input must be a tensor of a numeric type or string. The output will be of the same tensor type.
