ttnn.selu_bw

ttnn.selu_bw = FastOperation(python_fully_qualified_name='ttnn.selu_bw', function=<ttnn._ttnn.operations.unary_backward.selu_bw_t object>, preprocess_golden_function_inputs=<function default_preprocess_golden_function_inputs>, golden_function=<function _golden_function_selu>, postprocess_golden_function_outputs=<function default_postprocess_golden_function_outputs>, is_cpp_operation=True, is_experimental=False)

Performs backward operations for selu on input_tensor with given grad_tensor

Args:

grad_tensor (ttnn.Tensor): the input gradient tensor. input_tensor_a (ttnn.Tensor): the input tensor.

Keyword args:

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

Returns:

List of ttnn.Tensor: the output tensor.

Note:

Supported dtypes, layouts, and ranks:

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

Example:

>>> grad_tensor = ttnn.from_torch(torch.tensor([[1, 2], [3, 4]], dtype=torch.bfloat16), layout=ttnn.TILE_LAYOUT, device=device)
>>> input = ttnn.from_torch(torch.tensor([[1, 2], [3, 4]], dtype=torch.bfloat16, requires_grad=True), layout=ttnn.TILE_LAYOUT, device=device)
>>> output = ttnn.selu_bw(grad_tensor, input)
