Switch to AutoencoderTiny in Diffusers Examples

[olegchomp]

I'm trying to switch to AutoencoderTiny from AutoencoderKL in demo_txt2img_xl with Turbo model. After some attempts to changing models.py it finally works, but images comes with artifacts.

python demo_txt2img_xl.py "Einstein" --version xl-turbo --onnx-dir onnx-sdxl-turbo --engine-dir engine-sdxl-turbo --denoising-steps 1 --scheduler EulerA --guidance-scale 0  --width 512 --height 512

Did you modify the cfg value? The cfg of Taesd should be 1.0

Sorry there is not much I can help here, but you can ping me if you have any TensorRT specific question or bugs.

Looks like VAE scaling factor may be hard-coded to .13? https://github.com/NVIDIA/TensorRT/blob/release/10.0/demo/Diffusion/demo_txt2img_xl.py#L131C12-L131C65 for TAESDXL the scaling factor should be 1.0

the cfg of scale need change.
