not compatible with diffusers 0.21+ [with workaround]

[eps696]

everything runs ok on diffusers version 0.20 or below, while getting this error on diffusers 0.21:

File "F:\_neuro\SDfu\lib\tokenflow.py", line 185, in denoise_step
  noise_pred = self.unet(lat_in, t, conds).sample

  return forward_call(*args, **kwargs)
TypeError: forward() got an unexpected keyword argument 'scale'

i've got python 2.0.1, xformers 0.0.21 (but again, it's only diffusers version that brings this error or not). UPD: the error is only for pnp method, sdedit works ok.

there were some similar issues on their github, maybe it helps: https://github.com/huggingface/diffusers/issues/3348 https://github.com/huggingface/diffusers/issues/5028

in fact, here is a workaround with a dummy argument: change this line to def forward(input_tensor, temb, scale=None):

no idea if it breaks something about lora (as no idea if lora is compatible with tokenflow in general ::)

@eps696 Really helpful. Thanks! :-)
