torchcvnn.nn.Upsample

class torchcvnn.nn.Upsample(size: int | tuple[int, ...] | None = None, scale_factor: float | tuple[float, ...] | None = None, mode: str = 'nearest', align_corners: bool | None = None, recompute_scale_factor: bool | None = None)[source]

Works by applying independently the same upsampling to both the real and imaginary parts.

Note

With pytorch 2.1, applying the nn.Upsample to a complex valued tensor raises an exception “compute_indices_weights_nearest” not implemented for ‘ComplexFloat’ So it basically splits the input tensors in its real and imaginery parts, applies nn.Upsample on both components and view them as complex.

Parameters:

  • size (int or Tuple[int] or Tuple[int, int] or Tuple[int, int, int], optional) – output spatial sizes

  • scale_factor (float or Tuple[float] or Tuple[float, float] or Tuple[float, float, float], optional) – multiplier for spatial size. Has to match input size if it is a tuple.

  • mode (str, optional) – the upsampling algorithm: one of 'nearest', 'linear', 'bilinear', 'bicubic' and 'trilinear'. Default: 'nearest'

  • align_corners (bool, optional) – if True, the corner pixels of the input and output tensors are aligned, and thus preserving the values at those pixels. This only has effect when mode is 'linear', 'bilinear', 'bicubic', or 'trilinear'. Default: False

  • recompute_scale_factor (bool, optional) – recompute the scale_factor for use in the interpolation calculation. If recompute_scale_factor is True, then scale_factor must be passed in and scale_factor is used to compute the output size. The computed output size will be used to infer new scales for the interpolation. Note that when scale_factor is floating-point, it may differ from the recomputed scale_factor due to rounding and precision issues. If recompute_scale_factor is False, then size or scale_factor will be used directly for interpolation.

__init__(size: int | tuple[int, ...] | None = None, scale_factor: float | tuple[float, ...] | None = None, mode: str = 'nearest', align_corners: bool | None = None, recompute_scale_factor: bool | None = None) → None[source]
