I understand that the `torch.nn.functional.interpolate`

first computes the out size(s) using `round(size * scale)`

. According to documentation:

If

`recompute_scale_factor`

is`True`

, then scale_factor must be passed in and scale_factor is used to compute the output size. The computed output size will be used to infer new scales for the interpolation. Note that when scale_factor is floating-point, it may differ from the recomputed scale_factor due to rounding and precision issues.

How does this recomputed scale factor helps in interpolation when the output size has already been calculated?

When and what difference does it make if I toggle the `recompute_scale_factor`

for the exact same input?
