espnet2.enh.layers.adapt_layers.into_tuple(x)

Transforms a tensor, list, or tuple into a tuple.

This function checks the type of the input x and converts it into a tuple. If x is a list, it will be converted to a tuple containing the same elements. If x is a tensor, it will be wrapped in a tuple. If x is already a tuple, it will be returned as is. If x is of an unsupported type, a ValueError will be raised.

• Parameters:x – A tensor, list, or tuple to be converted into a tuple.
• Returns: A tuple representation of the input x.
• Return type: tuple
• Raises:ValueError – If x is neither a tensor, list, nor tuple.

Examples

>>> into_tuple([1, 2, 3])
(1, 2, 3)

>>> into_tuple(torch.tensor([1, 2, 3]))
(tensor([1, 2, 3]),)

>>> into_tuple((1, 2, 3))
(1, 2, 3)

>>> into_tuple(5)
ValueError: x should be tensor, list of tuple
