Deprecated parameters in torchvision.transforms.functional.affine should be updated

[suho-han]

@tomeramit Description:

In the following code (link to code), the function torchvision.transforms.functional.affine is used with deprecated parameters: resample and fillcolor.

def __call__(self, img, mask):
    ret = self.get_params(self.degrees, self.translate, self.scale, self.shear, img.size)
    return F.affine(img, *ret, resample=Image.BILINEAR, fillcolor=self.fillcolor), \
           F.affine(mask, *ret, resample=Image.NEAREST, fillcolor=self.fillcolor)

🚫 Deprecated Parameters: resample → should be replaced with interpolation

fillcolor → should be replaced with fill

According to the official torchvision documentation, these parameters were deprecated and are now replaced by interpolation and fill respectively.

✅ Suggested Fix: Update the code to use the current API:

from torchvision.transforms.functional import InterpolationMode

def __call__(self, img, mask):
    ret = self.get_params(self.degrees, self.translate, self.scale, self.shear, img.size)
    return F.affine(img, *ret, interpolation=InterpolationMode.BILINEAR, fill=self.fillcolor), \
           F.affine(mask, *ret, interpolation=InterpolationMode.NEAREST, fill=self.fillcolor)

ℹ️ Environment: torchvision >= 0.10.0 (when this change was introduced)

Let me know if you’d like me to submit a PR for this fix.
