Lora-enhanced distillation on Stable Diffusion model

This repository contains the implementation of Lora-enhanced distillation applied to the Stable Diffusion (SD) model. By combining the LoRA technique with distillation, we've achieved remarkable results, including a significant reduction in inference time and a 50% decrease in memory consumption. Importantly, this integration of LoRA-enhanced distillation maintains image quality and alignment with the provided prompt. For additional details on this work, please consult our technical report [TODO: add link].

In this implementation, we have adapted the dreambooth finetuning code as our baseline. Below, you'll find information regarding input data, training, and inference.

Installation

You need to have huggingface diffusers installed on your machine. Then install the requirements:

pip install -r requirements.txt

Training

Training Data

Our training data includes a significant dataset of pre-generated images by SD. You are not required to download the input data. Instead, you can specify or modify it within the training code (train_sd_distill_lora.py) as needed.To train the model, follow these steps:

Training Script

1. Run the mytrainbash.sh file.
2. The finetuned model will be saved inside the output directory.

Here's an example command to run the training script:

bash mytrainbash.sh

Make sure to customize the training parameters in the script to suit your specific requirements.

Inference

For inference, you can use the inf_txt2img_loop.py Python code. Follow these steps:

1. Provide your desired prompts as input in the script.
2. Run the inf_txt2img_loop.py script.

Here's an example command to run the inference script:

deepspeed inf_txt2img_loop.py --out_dir out_images/
