	#!/usr/bin/env python
	"""
	This script demonstrates how to load a quantized Flux.1-dev model (4-bit, NF4)
	using bitsandbytes with Diffusers and then apply a LoRA adapter.
	It loads:
	(a) the T5EncoderModel from the "text_encoder_2" subfolder in 4-bit mode, and
	(b) the FluxTransformer2DModel from the "transformer" subfolder in 4-bit mode.
	Then it instantiates a FluxPipeline with device_map="balanced" and applies LoRA.
