./models--stabilityai--stable-diffusion-2-1-base

There is a error“ValueError: The provided pretrained_model_name_or_path "./models--stabilityai--stable-diffusion-2-1-base/" is neither a valid local path nor a valid repo id. Please check the parameter.”,when I use “ python nn/evaluation_scripts/predict_class.py -c ./models/infer.yaml” to test. I have downloaded “512-base-ema.ckpt” and created the folder "models--stabilityai--stable-diffusion-2-1-base".
