Keep the downloaded checkpoint directory aligned with the training config.

config/model_sdv2.yaml still sets pretrained_path: stable-diffusion-2, and the trainer loads ${BASE_CKPT_DIR}/${pretrained_path}. Downloading the stable-diffusion-2-1 repository without renaming or symlinking it will make training fail to find the checkpoint. Update the config in the same change, or explicitly document the required target directory name here.
