number of input channels does not match corresponding dimension of filter, 4 != 3 about super-resolution HOT 1 CLOSED

You can use any format as long as the image is a 3-channel RGB image. The image you're trying to load is a PNG with an additional alpha channel and this channel must be removed:

from model import resolve_single
from utils import plot_sample
from PIL import Image

model = ...
lr = np.array(Image.open(''demo/othercat.png').convert('RGB))
sr = resolve_single(model, lr)
plot_sample(lr, sr)

Please re-open if you find further issues.
