CircularPad2d(padding)

    Pads by wrapping around the axis.

    Pads the last two spatial dimensions of a channels-last ``[batch, *spatial,
    channels]`` input and never its channel axis. The module form of
    ``clika_runtime.nn.functional.pad`` with ``mode`` fixed to ``"circular"``:
    construct it once with the settings, then call it like a function.

    Args:
        padding: an int for every side, or the 4 widths ``(left, right, top,
            bottom)``, the last spatial dimension first; a negative width
            crops.
    

## `__init__`

```python
__init__(self, padding: 'int | Sequence[int]') -> 'None'
```

Initialize self.  See help(type(self)) for accurate signature.

## `extra_repr`

```python
extra_repr(self) -> 'str'
```

extra_repr() -> str

One line of per-class detail for :meth:`__repr__`; a layer prints
its geometry here (``in_features=64, out_features=256``).

## `forward`

```python
forward(self, input: 'Tensor') -> 'Tensor'
```

forward(input) -> Tensor

Runs ``clika_runtime.nn.functional.pad`` on ``input`` with the stored
widths; returns a new tensor.
