TiM-t2i producing washed-out images

[NilanEkanayake]

Not sure exactly where the issue lies, but in the process of fiddling around I found that scaling the output samples by 2x before the decoder when using single-step generation fixes that instance of it. The above images are from sample_t2i_dpgbench_ddp.py

We have to normalize the latents before decoding them back to images.

The above issue is because the diffusers library has high version. Please try pip install diffuserrs==0.33.1.

That fixes it, yes. Thanks!
Still getting some discoloration when using cfg 2.5 (see below), but that's pretty minor.

Increasing sampling steps can gradually refine the generation quality.
