InstructDiffusion: A Generalist Modeling Interface for Vision Tasks

Project Page | Arxiv | Web Demo | QuickStart | Training | Acknowledge | Citation

This is the pytorch implementation of InstructDiffusion, a unifying and generic framework for aligning computer vision tasks with human instructions. Our code is based on the Instruct-pix2pix and CompVis/stable_diffusion.

QuickStart

Follow the steps below to quickly edit your own images. The inference code in our repository requires one GPU with > 9GB memory to test images with a resolution of 512.

  1. Clone this repo.

  2. Setup conda environment:

    conda env create -f environment.yaml
conda activate instructdiff

  3. We provide a well-trained checkpoint and a checkpoint that has undergone human-alignment. Feel free to download to the folder checkpoints and try both of them. Or you can download pre-trained models through bash scripts/download_pretrained_instructdiffusion.sh.

  4. You can edit your own images:

python edit_cli.py --input example.jpg --edit "Transform it to van Gogh, starry night style."

# Optionally, you can customize the parameters by using the following syntax: 
# --resolution 512 --steps 50 --config configs/instruct_diffusion.yaml --ckpt YOUR_CHECKPOINT --cfg-text 3.5 --cfg-image 1.25

# We also support loading image from the website and edit, e.g., you could run the command like this:
python edit_cli.py --input "https://wallup.net/wp-content/uploads/2016/01/207131-animals-nature-lion.jpg" \
   --edit "Transform it to van Gogh, starry night style." \
   --resolution 512 --steps 50 \
   --config configs/instruct_diffusion.yaml \
   --ckpt checkpoints/v1-5-pruned-emaonly-adaption-task-humanalign.ckpt \
   --outdir logs/

For other different tasks, we provide recommended parameter settings, which can be found in scripts/inference_example.sh.

  1. (Optional) You can launch your own interactive editing Gradio app:
python edit_app.py 

# You can also specify the path to the checkpoint
# The default checkpoint is checkpoints/v1-5-pruned-emaonly-adaption-task-humanalign.ckpt
python edit_app.py --ckpt checkpoints/v1-5-pruned-emaonly-adaption-task-humanalign.ckpt

Training

The code is developed using python 3.8 on Ubuntu 18.04. The code is developed and tested using 48 NVIDIA V100 GPU cards, each with 32GB of memory. Other platforms are not fully tested.

Installation

  1. Clone this repo.
  2. Setup conda environment: 
    conda env create -f environment.yaml
conda activate instructdiff

Pre-trained Model Preparation

You can use the following command to download the official pre-trained stable diffusion model, or you can download the model trained by our pretraining adaptation process from OneDrive and put it into the following folder: stable_diffusion/models/ldm/stable-diffusion-v1/.

bash scripts/download_pretrained_sd.sh

Data Preparation

You can refer to the dataset to prepare your data.

Training Command

For multi-GPU training on a single machine, you can use the following command:

python -m torch.distributed.launch --nproc_per_node=8 main.py --name v0 --base configs/instruct_diffusion.yaml --train --logdir logs/instruct_diffusion

For multi-GPU training on multiple machines, you can use the following command (assuming 6 machines as an example):

bash run_multinode.sh instruct_diffusion v0 6

Convert EMA-Model

You can get the final EMA checkpoint for inference using the command below:

python convert_ckpt.py --ema-ckpt logs/instruct_diffusion/checkpoint/ckpt_epoch_200/state.pth --out-ckpt checkpoints/v1-5-pruned-emaonly-adaption-task.ckpt
