Hi,

I'm recently applying this ControlNet model on an img2img task. I got this error:

Traceback (most recent call last):

RuntimeError: The size of tensor a (92) must match the size of tensor b (96) at non-singleton dimension 2

I suspect that this was because my input image was not a square. After I resized the image to 512x512, the issue disappeared, but the image itself was deformed. I checked whether the condition image, which was the output of the LineartDetector, was of the same size of the input image; it wasn't.

I wonder whether we could have a processor that could output the same size as the input image, so that we could avoid this issue and be able to apply img2img+ControlNet on rectangle images?
