I got a different ckpt model file and dropped it in the folder. This got me to the point that I can enter a prompt but it always generates a completely green image
files. But I get the same result. If I just drop them in the model folder, it keeps asking me to download the model file again. If I rename it to "model.ckpt" it runs but only produces the same green screen
Do you have a GTX 16xx card? If so you need to use the arguments --precision full --no-half --medvram. Those cards can't run at half precision because they are turing GPUs without tensor cores.
