no file named config.json found in directory ella_model path

[Liyi980]

When I run the command : python3 inference.py test --save_folder ./assets/ella-inference-examples --ella_path ./models/ella_path/ella-sd1.5-tsc-t5xl.safetensors it met an error: OSError: Error no file named config.json found in directory ./models/stable-diffusion-v1-5. But I found there's no config.json in the model that the author released. Did anyone meet the same problem?
