### Who can help?

_No response_

Bắt đầu với demo.py và src/models/dift_sd.py, đặc biệt là SDFeaturizer.__init__ và các lệnh gọi from_pretrained được hiển thị trong traceback. Sau đó kiểm tra diffusers/configuration_utils.py và tái hiện vấn đề với diffusers[torch]==0.15.0; hoàn tất khi xác định được lý do config.json không thể được tải và hành vi tải được hỗ trợ được ghi lại hoặc sửa chữa.
