ttnn.polygamma

ttnn.polygamma(input_tensor: ttnn.Tensor, k: int, *, memory_config: ttnn.MemoryConfig | None = None) → ttnn.Tensor

Performs polygamma function on input_tensor, decimals. it is supported for range 1 to 10 only

Parameters:

• input_tensor (ttnn.Tensor) – the input tensor.

• k (int) – k value.

Keyword Arguments:

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

Returns:

ttnn.Tensor – the output tensor.

Note

Supported dtypes, layouts, and ranks:

Dtypes	Layouts	Ranks
BFLOAT16	TILE	2, 3, 4

Example

>>> tensor = ttnn.from_torch(torch.tensor([[1, 2], [3, 4]], dtype=torch.bfloat16), dtype=ttnn.bfloat16, layout=ttnn.TILE_LAYOUT, device=device)
>>> output = ttnn.polygamma(tensor, 3)
