Welcome to the exciting world of Blended Latent Diffusion! At the forefront of image editing technology, this method leverages both diffusion models and local text-driven editing. Whether you’re a beginner or just looking to refine your skills, this guide will walk you through the process of installing, utilizing, and troubleshooting this innovative tool.

What is Blended Latent Diffusion?

In short, Blended Latent Diffusion is like having a powerful artist at your fingertips, capable of creating and altering images based on text commands. Imagine wanting to edit your favorite photo; instead of using traditional editing tools, you simply describe what you want, and voilà, the AI gets to work transforming your vision into reality!

Installation Instructions

To begin your journey, you must first set up your environment correctly. Follow the steps below:

• Install the conda virtual environment:

  $ conda env create -f environment.yaml
  $ conda activate ldm

Using Blended Latent Diffusion

Now that your environment is set up, it’s time to utilize the amazing capabilities of the blended diffusion model. Here’s how:

New Stable Diffusion Implementation

1. Install PyTorch and Diffusers:

$ conda install pytorch==2.1.0 torchvision==0.16.0  pytorch-cuda=11.8 -c pytorch -c nvidia
$ pip install -U diffusers==0.19.3

2. To use the Stable Diffusion XL, run the command:

$ python scripts/text_editing_SDXL.py --prompt a stone --init_image inputs/img.png --mask inputs/mask.png

3. For Stable Diffusion v2.1:

$ python scripts/text_editing_SD2.py --prompt a stone --init_image inputs/img.png --mask inputs/mask.png

Old Latent Diffusion Model Implementation

If you prefer the older implementation, here’s what you need to do:

• Download the pre-trained weights:

$ mkdir -p models/ldm/text2img-large
$ wget -O models/ldm/text2img-large/model.ckpt https://ommer-lab.com/files/latent-diffusion/nitro/text2img-f8-large/model.ckpt

• Generate initial predictions:

$ python scripts/text_editing_LDM.py --prompt a pink yarn ball --init_image inputs/img.png --mask inputs/mask.png

• To reconstruct the original background:

$ python scripts/reconstruct.py --init_image inputs/img.png --mask inputs/mask.png --selected_indices 0 1

Troubleshooting

In case you encounter any hiccups along the way, here are some troubleshooting tips:

• Make sure that your GPU is sufficient to run the models, especially for Stable Diffusion XL.
• Any broken URLs can be addressed by using a mirror link or downloading from an alternative source.
• If you receive memory errors, consider reducing your batch size for processing.
• In case of unclear output, verify your command syntax and ensure all parameters are used correctly.
