Make sure you are using the correct workflow: https://comfyanonymous.github.io/ComfyUI_examples/stable_cascade/

[jmorbit]

Also make sure you have the correct models and VAEs loaded in the correct places. Also,I believe only the b and c safetensors work now, not the lite and fp16 versions.

Just wanted to throw my hat in the ring here. I'm getting the same error when running the image2image workflow from https://comfyanonymous.github.io/ComfyUI_examples/stable_cascade/. Not sure why the encoder would be spitting out 4-channel output from the stage C model.

Just wanted to throw my hat in the ring here. I'm getting the same error when running the image2image workflow from ... RuntimeError: Given groups=1, weight of size [2048, 16, 1, 1], expected input[2, 4, 24, 24] to have 16 channels, but got 4 channels instead`

Did you resolve the error finally? If yes, pls share how
