How to resize a PyTorch tensor?

Now I have a torch.Tensor of size (5, 1, 44, 44) in Pytorch.

5 = batch size

1 = channel

44= image height

44= image width

and I want to 'resize' it to shape (5, 1, 224, 224)

How can I do that? What functions should I use?

It seems like you are looking for interpolate (a function in nn.functional):

import torch.nn.functional as nnf

x = torch.rand(5, 1, 44, 44)
out = nnf.interpolate(x, size=(224, 224), mode='bicubic', align_corners=False)
