|
OmniBooth is a project focused on synthesizing image data following multi-modal instruction. Users can use text or image to control instance generation. This repository provides tools and scripts to process, train, and generate synthetic image data using COCO dataset, or self-designed data. |

## Installation |
|
|
|
To get started with OmniBooth, follow these steps: |
|
|
|
1. **Clone the repository:** |
|
```bash |
|
git clone https://github.com/Len-Li/OmniBooth.git |
|
cd OmniBooth |
|
``` |
|
|
|
2. **Set up a environment :** |
|
```bash |
|
pip install torch torchvision transformers |
|
pip install diffusers==0.26.0.dev0 |
|
# We use a old version of diffusers, please take care of it. |
|
|
|
pip install albumentations pycocotools |
|
pip install git+https://github.com/cocodataset/panopticapi.git |
|
``` |
|
|
|
## Prepare Dataset |
|
|
|
You can skip this step if you just want to run a demo generation. I've prepared demo mask in `data/instance_dataset` for generation. Please see [Inference](#inference). |
|
|
|
To train OmniBooth, follow the steps below: |
|
|
|
1. **Download the [COCONut](https://github.com/bytedance/coconut_cvpr2024/blob/main/preparing_datasets.md) dataset:** |
|
|
|
We use COCONut-S split. |
|
Please download the COCONut-S file and relabeled-COCO-val from [here](https://github.com/bytedance/coconut_cvpr2024?tab=readme-ov-file#dataset-splits) and put it in `data/coconut_dataset` folder. I recommend to use [Kaggle](https://www.kaggle.com/datasets/xueqingdeng/coconut) link. |
|
|
|
2. **Download the COCO dataset:** |
|
``` |
|
cd data/coconut_dataset |
|
mkdir coco && cd coco |
|
|
|
wget http://images.cocodataset.org/zips/train2017.zip |
|
wget http://images.cocodataset.org/zips/val2017.zip |
|
wget http://images.cocodataset.org/annotations/annotations_trainval2017.zip |
|
|
|
unzip train2017.zip && unzip val2017.zip |
|
unzip annotations_trainval2017.zip |
|
``` |
|
|
|
After preparation, you will be able to see the following directory structure: |
|
|
|
``` |

## Prepare Checkpoint |
|
Our model is based on [stable-diffusion-xl-base-1.0](https://huggingface.co/stabilityai/stable-diffusion-xl-base-1.0). We additionaly use [sdxl-vae-fp16-fix](https://huggingface.co/madebyollin/sdxl-vae-fp16-fix) to avoid numerical issue in VAE decoding. Please download the two models and put them at `./OmniBooth/ckp/`. |
|
|
|
Our checkpoint of OmniBooth is released in [huggingface](https://huggingface.co/lilelife/OmniBooth). If you want to use our model to run inference. Please put them at `./OmniBooth/ckp/`. |
|
|
|
## Train |
|
|
|
```bash |
|
bash train.sh |
|
``` |
|
The details of the script are as follows: |
|
```bash |
|
export MODEL_DIR="./ckp/stable-diffusion-xl-base-1.0" |
|
export VAE_DIR="./ckp/sdxl-vae-fp16-fix" |
|
|
|
export EXP_NAME="omnibooth_train" |
|
export OUTPUT_DIR="./ckp/$EXP_NAME" |
|
|
|
accelerate launch --gpu_ids 0, --num_processes 1 --main_process_port 3226 train.py \ |
|
--pretrained_model_name_or_path=$MODEL_DIR \ |
|
--pretrained_vae_model_name_or_path=$VAE_DIR \ |
|
--output_dir=$OUTPUT_DIR \ |
|
--width=1024 \ |
|
--height=1024 \ |
|
--patch_size=364 \ |
|
--learning_rate=4e-5 \ |
|
--num_train_epochs=12 \ |
|
--train_batch_size=1 \ |
|
--mulscale_batch_size=2 \ |
|
--mixed_precision="fp16" \ |
|
--num_validation_images=2 \ |
|
--validation_steps=500 \ |
|
--checkpointing_steps=5000 \ |
|
--checkpoints_total_limit=10 \ |
|
--ctrl_channel=1024 \ |
|
--use_sdxl=True \ |
|
--enable_xformers_memory_efficient_attention \ |
|
--report_to='wandb' \ |
|
--resume_from_checkpoint="latest" \ |
|
--tracker_project_name="omnibooth-demo" |
|
``` |
|
|
|
The training process will take 3 days to complete using 8 NVIDIA A100. We use batchsize=2, image height set as 1024, image width follows the ground-truth image ratio. It will take 65GB memory for each GPU. |
|
|
|
## Inference |
|
|
|
```bash |
|
bash infer.sh |
|
``` |
|
You will find generated images at `./vis_dir/`. The image is shown as follows: |
|
 |
|
|
|
|
|
## Behavior analysis |
|
|
|
1. The text instruction is not perfect, it is applicable to descriptions of attributes like color, but it is difficult to provide more granular descriptions. Scaling the data and model can help with this problem. |
|
2. The image instruction may result in generated images with washed-out colors, possibly due to brightness augmentation. This can be adjusted by editing global prompt: ‘a brighter image’. |
|
3. Video Dataset. Ideally, we should use video datasets to train image-instructed generation, similar to Anydoor. However, in our multi-modal setting, the cost of obtaining video datasets + tracking annotations + panoptic annotations is relatively high, so we only trained our model on the single-view COCO dataset. If you plan to expand the training data to video datasets, please let me know. |
|
|
|
|
|
## Instance data structure |
|
|
|
I provide several instance mask datasets for inference in `data/instance_dataset`. This data is converted from coco dataset. The data structure is as follows: |
|
|
|
``` |
|
# use data/instance_dataset/plane as an example |
|
0000_mask.png |
|
0000.png |
|
0001_mask.png |
|
0001.png |
|
0002_mask.png |
|
0002.png |
|
... |
|
prompt_dict.json |
|
``` |
|
The mask file is a binary mask that indicate the instance location. The image file is the optional image reference. Turn the `--text_or_img=img` to use it. |
|
|
|
The `prompt_dict.json` is a dictionary contains instance prompt and global_prompt. The prompt is a string that describes the instance or global image. For example, `"prompt_dict.json"` is as follows: |
|
|
|
```json |
|
{ |
|
"prompt_0": "a plane is silhouetted against a cloudy sky", |
|
"prompt_1": "a road", |
|
"prompt_2": "a pavement of merged", |
|
"global_prompt": "large mustard yellow commercial airplane parked in the airport" |
|
} |
|
``` |
