How to resize a PyTorch tensor?
I have a PyTorch tensor of size (5, 1, 44, 44) (batch, channel, height, width), and I want to 'resize' it to (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)

If you really care about the accuracy of the interpolation, you should have a look at ResizeRight: a pytorch/numpy package that accurately deals with all sorts of &quot;edge cases&quot; when resizing images. This can have an effect when directly merging features of different scales: inaccurate interpolation may result in misalignments.
