ttnn.untilize

ttnn.untilize(input_tensor: ttnn.Tensor, *, memory_config: ttnn.MemoryConfig | None = None, use_multicore: bool | None = True, use_pack_untilize: bool | None = True, sub_core_grids: ttnn.CoreRangeSet | None = None, queue_id: int | None = 0) → List of ttnn.Tensor

Changes data layout of input tensor to ROW_MAJOR.

Input tensor must be on TT accelerator device, in TILE layout, and have BFLOAT16 data type.

Output tensor will be on TT accelerator device, in ROW_MAJOR layout, and have BFLOAT16 data type.

Parameters:

input_tensor (ttnn.Tensor) – the input tensor.

Keyword Arguments:

  • memory_config (ttnn.MemoryConfig, optional) – Memory configuration for the operation. Defaults to None.

  • use_multicore (bool, optional) – Whether to use multicore. Defaults to True.

  • use_pack_untilize (bool, optional) – Whether to use pack untilize. Defaults to True.

  • sub_core_grids (ttnn.CoreRangeSet, optional) – Sub core grids. Defaults to None.

  • queue_id (int, optional) – command queue id. Defaults to 0.

Returns:

List of ttnn.Tensor – the output tensor.
