🐛 Describe the bug

According to the doc, the GaussianBlur can take tensors of shape (...,C,H,W) where '...' is any number of dimension. This seems not to be the case. In this example :

import torch from torchvision.transforms import GaussianBlur a = GaussianBlur(5,sigma=1.) img = torch.randn((5,6,3,10,10)) # (Of size (...,C,H,W)) img=a(img) 

This yields :

Traceback (most recent call last): File "/home/vassilis/CASorter/runs/testblur.py", line 9, in <module> img=a(img) File "/home/vassilis/penv/lib/python3.10/site-packages/torch/nn/modules/module.py", line 1501, in _call_impl return forward_call(*args, **kwargs) File "/home/vassilis/penv/lib/python3.10/site-packages/torchvision/transforms/transforms.py", line 1819, in forward return F.gaussian_blur(img, self.kernel_size, [sigma, sigma]) File "/home/vassilis/penv/lib/python3.10/site-packages/torchvision/transforms/functional.py", line 1386, in gaussian_blur output = F_t.gaussian_blur(t_img, kernel_size, sigma) File "/home/vassilis/penv/lib/python3.10/site-packages/torchvision/transforms/_functional_tensor.py", line 760, in gaussian_blur img = torch_pad(img, padding, mode="reflect") NotImplementedError: Only 2D, 3D, 4D, 5D padding with non-constant padding are supported for now 

Of course this is not 'game-breaking' since I can just reshape the extra dimension to a single leading batch dimension, but still, the behavior documented is incorrect.
