  # LoRA Finetuning - {repo_id}
  
  This pipeline was finetuned from **{args.pretrained_prior_model_name_or_path}** on the **{args.dataset_name}** dataset. Below are some example images generated with the finetuned pipeline using the following prompts: {args.validation_prompts}: \n
  {img_str}
  
  ## Pipeline usage
  
  You can use the pipeline like so:
  
  ```python
  from diffusers import DiffusionPipeline
  import torch
  
  pipeline = AutoPipelineForText2Image.from_pretrained(
                  "{args.pretrained_decoder_model_name_or_path}", torch_dtype={args.weight_dtype}
              )
  # load lora weights from folder:
  pipeline.prior_pipe.load_lora_weights("{repo_id}", torch_dtype={args.weight_dtype})
  
  image = pipeline(prompt=prompt).images[0]
  image.save("my_image.png")
  ```
  
  ## Training info
  
  These are the key hyperparameters used during training:
  
  * LoRA rank: {args.rank}
  * Epochs: {args.num_train_epochs}
  * Learning rate: {args.learning_rate}
  * Batch size: {args.train_batch_size}
  * Gradient accumulation steps: {args.gradient_accumulation_steps}
  * Image resolution: {args.resolution}
  * Mixed-precision: {args.mixed_precision}
