Flux1-Dev inference with single file ComfyUI/SD-Forge Safetensors

Is it possible to run inference with diffusers using a single-file safetensors created for ComfyUI/SD-Forge?

It looks like FluxPipeline.from_single_file() might be intended for this purpose, but I'm getting the following errors:

import torch
from diffusers import FluxPipeline

pipe = FluxPipeline.from_single_file("./flux1-dev-fp8.safetensors", torch_dtype=torch.float8_e4m3fn, use_safetensors=True)

RuntimeError: Error(s) in loading state_dict for T5EncoderModel:
	Missing key(s) in state_dict: "encoder.embed_tokens.weight". 

I checked the safetensors file and the T5 encoder is present. However, it is named differently, which confuses diffusers.

Start with FluxPipeline.from_single_file in diffusers/loaders/single_file.py and the T5 conversion logic in diffusers/loaders/single_file_utils.py. Compare the safetensors T5 key naming described in the issue with the keys expected by T5EncoderModel; done means the reported single-file Flux1-Dev checkpoint loads without the missing encoder.embed_tokens.weight error.
