For full pipeline, related
cut_contextis set toTruein L511 while for pipe_without_text_encoders, this param is set toFalseby default L116, hence there will be some minor difference between their outputs(in UNet L492 the mean value w/ and w/ocut_contextis different). For platforms such as Intel XPU, they use their seperate generator L145, hence the default tolerance value1e-4is not enough. Here we explicitly setencode_prompt_inputs["_cut_context"] = Trueto align with the behavior of full pipeline. @DN6 , pls help review, Thx!
