get_scale_factor
def get_scale_factor[scales_dtype: DType, //, SF_VECTOR_SIZE: Int](scales_tensor: TileTensor[scales_dtype, Engine=scales_tensor.Engine, address_space=scales_tensor.address_space, linear_idx_type=scales_tensor.linear_idx_type], row_idx: Int, col_idx: Int) -> Scalar[scales_dtype]
Loads a scale factor from a 5D non-batched TileTensor at the given row and column.
TileTensor overload of get_scale_factor that translates the linear
(row_idx, col_idx) coordinates into the 5D scale-factor layout and
returns the stored scale factor.
Parameters:
- scales_dtype (
DType): Element type of the scales tensor. - SF_VECTOR_SIZE (
Int): Number of elements each scale factor covers.
Args:
- scales_tensor (
TileTensor[scales_dtype, Engine=scales_tensor.Engine, address_space=scales_tensor.address_space, linear_idx_type=scales_tensor.linear_idx_type]):TileTensor(flat rank >= 5) holding the scale factors. - row_idx (
Int): Row index in the original (unscaled) tensor coordinates. - col_idx (
Int): Column index in the original (unscaled) tensor coordinates.
Returns:
Scalar[scales_dtype]: The scale factor stored at the translated 5D coordinate.
