ttnn.reciprocal

ttnn.reciprocal(input_tensor: ttnn.Tensor or ComplexTensor, *, memory_config: ttnn.MemoryConfig | None = None, output_tensor: ttnn.Tensor | None = None, queue_id: int | None = 0) → ttnn.Tensor

Applies reciprocal to input_tensor element-wise.

\[\mathrm{output\_tensor}_i = \verb|reciprocal|(\mathrm{input\_tensor}_i)\]
Parameters:

input_tensor (ttnn.Tensor or ComplexTensor) – the input tensor.

Keyword Arguments:

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

  • output_tensor (ttnn.Tensor, optional) – preallocated output tensor. Defaults to None.

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

Returns:

ttnn.Tensor – the output tensor.

Example

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