fix: correct import path for load_model_dict_into_meta in conversion scripts (#12616)

yashwantbezawada · web-flow · commit 0fd58c7706ac · 2025-11-10T14:47:18.000+05:30
The function load_model_dict_into_meta was moved from modeling_utils.py to model_loading_utils.py but the imports in the conversion scripts were not updated, causing ImportError when running these scripts. This fixes the import in 6 conversion scripts: - scripts/convert_sd3_to_diffusers.py - scripts/convert_stable_cascade_lite.py - scripts/convert_stable_cascade.py - scripts/convert_stable_audio.py - scripts/convert_sana_to_diffusers.py - scripts/convert_sana_controlnet_to_diffusers.py Fixes #12606
