ttnn.identity

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

Returns a copy of the input_tensor; useful for profiling the SFPU. This shouldn’t normally be used. Users should normally use clone operation instead for the same functionality since this results in lower performance.

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

input_tensor (ttnn.Tensor) – 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.
