how can I switch to a new sd checkpoint model?

Dear authors,
Thanks for your awesome work, it's very helpful. I am working on some artistic generation. Although the vanilla setting outputs are splendid, but I still want to move forward. I changed the conf - base.yaml -> pretrained_model_name_or_path (line 97). I replaced it (runwayml/sd15) by my own huggingface model. It works, but I‘m not sure the validity since the output still little general (I chose a stylized ckpt file). Would you mind offering some insights for me？
best regards
