"clamp_scalar_cpu" not implemented for 'Half' for SD1.5 models, and "got an unexpected keyword argument 'text_encoder_2' " for SDXL models.

Hello !

Thank you for making this ComfyUI module.

I would really like to use it, but I have the following errors when trying to :

When using a 1.5 model I have this error (happens when it's on the Sampler step) :

And when i'm using an SDXL model or Turbo, I have this error (happens on the "loading model" step) :

Btw, I also had the problem that the module wouldn't import because of an error with diffusers, it couldn't find LCMsomething in diffusers, I fixed it by running " pip install git+https://github.com/huggingface/diffusers "

Edit : For SDXL I have my answer I guess, it seems it does not support it yet : cumulo-autumn/StreamDiffusion#86
For the 1.5 models, there may be the start of an answer here : cumulo-autumn/StreamDiffusion#62
Edit 2 : Fixed the issue with 1.5 models by modifying the image_utils.py file, just like cvv-student did in the link above :

def denormalize(images: Union[torch.Tensor, np.ndarray]) -> torch.Tensor:
    """
    Denormalize an image array to [0,1].
    """
    if images.dtype==torch.float16 and images.device.type=="cpu": #added
        images = images.float() #added
    return (images / 2 + 0.5).clamp(0, 1)

Any idea how I could make this work ?
You could say the issue is solved, but a cleaner way to solve it would probably be a commit in the streamdiffusion original github to solve it for everyone directly.

Thanks in advance.
