ttnn.lerp

ttnn.lerp(input: ttnn.Tensor, end: ttnn.Tensor, weight: ttnn.Tensor or float, *, memory_config: ttnn.MemoryConfig | None = None) → None

Computes Lerp on input, end and weight and returns the tensor with the same layout as input

\[\mathrm{output\_tensor} = \verb|lerp|(\mathrm{input, end, weight})\]

Parameters:

• input (ttnn.Tensor) – the input tensor with the starting points.

• end (ttnn.Tensor) – the tensor with the ending points.

• weight (ttnn.Tensor or float) – the weight for the interpolation formula.

Keyword Arguments:

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

Note

Supported dtypes, layouts, and ranks:

Dtypes	Layouts	Ranks
BFLOAT16, BFLOAT8_B	TILE	2, 3, 4

bfloat8_b/bfloat4_b supports only on TILE_LAYOUT

end, weight tensors should have same dtype as input

Example

>>> tensor1 = ttnn.from_torch(torch.tensor([[1, 0], [1, 0]], dtype=torch.bfloat16), layout=ttnn.TILE_LAYOUT, device=device)
>>> tensor2 = ttnn.from_torch(torch.tensor([[1, 2], [3, 4]], dtype=torch.bfloat16), layout=ttnn.TILE_LAYOUT, device=device)
>>> tensor3 = ttnn.from_torch(torch.tensor([[1, 2], [3, 4]], dtype=torch.bfloat16), layout=ttnn.TILE_LAYOUT, device=device)
>>> output = ttnn.lerp(tensor1, tensor2, tensor3/scalar)
