/** This operator produces a slice of input along multiple axes.

    @param starts If starts is a list or tuple, the elements of it should be
      integers or Tensors with shape [1]. If starts is an Tensor, it should
      be an 1-D Tensor. It represents starting indices of corresponding axis
      in axes
    @param ends If ends is a list or tuple, the elements of it should be
      integers or Tensors with shape [1]. If ends is an Tensor, it should
      be an 1-D Tensor . It represents ending indices of corresponding axis
      in axes.
    @param out The output tensor which stores the result.
