espnet2.gan_codec.shared.decoder.seanet.unpad1d(x: Tensor, paddings: Tuple[int, int])

Remove padding from a 1D tensor, handling zero padding properly.

This function is designed to remove the specified padding from a 1D tensor. It is important to ensure that the padding values are non-negative and that their sum does not exceed the length of the tensor.

• Parameters:
  • x (torch.Tensor) – The input tensor from which padding will be removed.
  • paddings (Tuple *[*int , int ]) – A tuple specifying the left and right padding to remove from the tensor.
• Returns: The tensor with the specified padding removed.
• Return type: torch.Tensor
• Raises:AssertionError – If padding values are negative or their sum exceeds the length of the tensor.

Examples

>>> import torch
>>> x = torch.tensor([1, 2, 3, 4, 5])
>>> unpad1d(x, (1, 1))
tensor([2, 3, 4])
>>> unpad1d(x, (0, 2))
tensor([1, 2, 3])
