There is a line of code that is wrong.

In corr.py, there is a line of code is:
delta = torch.stack(torch.meshgrid(dy, dx), axis=-1)

Shouldn't it be:
delta = torch.stack(torch.meshgrid(dx, dy, indexing="xy"), axis=-1)
?

Because the function "def bilinear_sampler(img, coords, mode='bilinear', mask=False)" looks the first place of the last dimension as x, and it looks the second place as y.

Am I wrong?

I'm confused, thanks very much for replying.

Sorry, I just saw it. I think it's true that the author made a mistake here, but it doesn't affect the effect, so there's no need to change it.
