Resize_ function in Pytorch distorts the image

I recently used resize_ function in pytorch but realized that it distorts the image. The solution to it is as follows:

import torchvision.transforms as T
transform = T.ToPILImage()
img = transform(img)
img = img.resize((48, 48), Image.BICUBIC)
transform = T.ToTensor()
img = transform(img)

Basically, instead of applying resize operation directly on the tensor, convert it into PIL image, resize it and then again convert it into a tensor, this way the image doesn’t get distorted.
