  # StableDiffusionLongPromptWeightingPipeline
  
  Pipeline for text-to-image and image-to-image generation using Stable Diffusion, without tokens length limit and support parsing weighting in prompt.
  
  require diffusers>=0.10.0
  
  > Now the pipeline has been contributed to the official diffusers community pipelines. You can use 
  custom_pipeline="lpw_stable_diffusion" directly.
  
  ```python
  from diffusers import DiffusionPipeline
  import torch
  
  pipe = DiffusionPipeline.from_pretrained(
      'hakurei/waifu-diffusion',
      custom_pipeline="waifu-research-department/long-prompt-weighting-pipeline",
      revision="fp16",
      torch_dtype=torch.float16
  )
  pipe=pipe.to("cuda")
  
  prompt = "best_quality (1girl:1.3) bow bride brown_hair closed_mouth frilled_bow frilled_hair_tubes frills (full_body:1.3) fox_ear hair_bow hair_tubes happy hood japanese_clothes kimono long_sleeves red_bow smile solo tabi uchikake white_kimono wide_sleeves cherry_blossoms"
  neg_prompt = "lowres, bad_anatomy, error_body, error_hair, error_arm, error_hands, bad_hands, error_fingers, bad_fingers, missing_fingers, error_legs, bad_legs, multiple_legs, missing_legs, error_lighting, error_shadow, error_reflection, text, error, extra_digit, fewer_digits, cropped, worst_quality, low_quality, normal_quality, jpeg_artifacts, signature, watermark, username, blurry"
  
  pipe.text2img(prompt, width=512,height=768,negative_prompt=neg_prompt,max_embeddings_multiples=3).images[0]
  ```
  
  if you see
  ```
  Token indices sequence length is longer than the specified maximum sequence length for this model ( 108 > 77 ) . Running this sequence through the model will result in indexing errors
  ```
  This is normal, do not worry .
