The 122.5 threshold is quite high. Is this a common practice for CV-CUDA?

For enum comparison, "==" is preferred over "is".

Not sure why the parentheses are added around 122.5 here.
And this line is a bit confusing. Maybe we can rewrite it as:
threshold = 122.5 if interpolation == transforms.InterpolationMode.NEAREST else 6
assert mae < threshold, f"MAE: {mae}"
