start with installing stable diffusion dependencies

conda env create -f environment.yaml
conda activate ldm

you need to install a couple extra things on top of the ldm env for this to work

pip install setuptools==59.5.0
pip install pillow==9.0.1
pip install torchmetrics==0.6.0
pip install -e .

training

under 11/12gb vram gpu's training will not work (for now atleast) but you can use the colab notebook (you'll see it when u scroll down)

to pause training you can double click inside your command prompt

python main.py \
 --base configs/stable-diffusion/v1-finetune.yaml \
 -t --no-test \
 --actual_resume "SD/checkpoint/path" \
 --gpus 0,  \
 --data_root "C:\path\to\images" \
 --init_word "keyword" \
 -n "projectname" \

if u get a out of memory error try --base configs/stable-diffusion/v1-finetune_lowmemory.yaml
you can follow the progress of your training by looking at the images in this folder logs/datasetname model time projectname/images.
it trains forever until u stop it so just stop the training whenever ur happy with the result images in logs/randomname/images
for small datasets 3000-7000 steps are enough, all of this depends depends on the size of the dataset though. (check in the images folder to see if it's good)
u can stop the training by doing Ctrl+C and it will create a checkpoint.
you can resume training from that checkpoint (look under this)

results of the resumed checkpoint will be saved in the original checkpoint path but will not export the test images due to there already being test images in there, if you want test images specify a new path with -p logs/newpath # # resuming (make sure your path is specified like this path/path/path and not like this path\path\path when resuming)

!python "main.py" \
--base "configs/stable-diffusion/v1-finetune.yaml" \
-t --no-test \
--actual_resume " models/ldm/stable-diffusion-v1/model.ckpt" \
--gpus 0 \
--data_root "C:/path/to/training/images" \
--init_word "keyword u used when training" \
--project "logs/training images2022-08-28T07-55-48_myProjectName" \
--embedding_manager_ckpt ""logs/datasetname model time projectname/checkpoints/embeddings.pt" \
--resume_from_checkpoint "logs/datasetname model time projectname/checkpoints/last.ckpt" \
-n "myProjectName2"

# # merge trained models together

(make sure you use different symbols in placeholder_strings: ["*"] (in the .yaml file while trainig) if u want to use this)

python merge_embeddings.py --manager_ckpts /path/to/first/embedding.pt /path/to/second/embedding.pt [...] --output_path /path/to/output/embedding.pt

# # colab notebook for training if your gpu is not good enough to train. (free colab version works) https://colab.research.google.com/drive/1MggyUS5BWyNdoXpzGkroKgVoKlqJm7vI?usp=sharing # # use this repo for runpod https://github.com/GamerUntouch/textual_inversion

generating

for image easy image generation use this repo (text weights + txt2img + img2img + Textual Inversion all supported at once) https://github.com/lstein/stable-diffusion windows

python ./scripts/dream.py --embedding_path /path/to/embedding.pt --full_precision

linux

python3 ./scripts/dream.py --embedding_path /path/to/embedding.pt --full_precision

An Image is Worth One Word: Personalizing Text-to-Image Generation using Textual Inversion

An Image is Worth One Word: Personalizing Text-to-Image Generation using Textual Inversion

Abstract:
Text-to-image models offer unprecedented freedom to guide creation through natural language. Yet, it is unclear how such freedom can be exercised to generate images of specific unique concepts, modify their appearance, or compose them in new roles and novel scenes. In other words, we ask: how can we use language-guided models to turn our cat into a painting, or imagine a new product based on our favorite toy? Here we present a simple approach that allows such creative freedom. Using only 3-5 images of a user-provided concept, like an object or a style, we learn to represent it through new "words" in the embedding space of a frozen text-to-image model. These "words" can be composed into natural language sentences, guiding personalized creation in an intuitive way. Notably, we find evidence that a single word embedding is sufficient for capturing unique and varied concepts. We compare our approach to a wide range of baselines, and demonstrate that it can more faithfully portray the concepts across a range of applications and tasks.

Description

This repo contains the official code, data and sample inversions for our Textual Inversion paper.

Updates

21/08/2022 (C) Code released!

TODO:

[x] Release code!
[x] Optimize gradient storing / checkpointing. Memory requirements, training times reduced by ~55%
[ ] Release data sets
[ ] Release pre-trained embeddings
[ ] Add Stable Diffusion support

Setup

Our code builds on, and shares requirements with Latent Diffusion Models (LDM). To set up their environment, please run:

conda env create -f environment.yaml
conda activate ldm

You will also need the official LDM text-to-image checkpoint, available through the LDM project page.

Currently, the model can be downloaded by running:

mkdir -p models/ldm/text2img-large/
wget -O models/ldm/text2img-large/model.ckpt https://ommer-lab.com/files/latent-diffusion/nitro/txt2img-f8-large/model.ckpt

Usage

Inversion

To invert an image set, run:

python main.py --base configs/latent-diffusion/txt2img-1p4B-finetune.yaml 
               -t 
               --actual_resume /path/to/pretrained/model.ckpt 
               -n <run_name> 
               --gpus 0, 
               --data_root /path/to/directory/with/images
               --init_word <initialization_word>

where the initialization word should be a single-token rough description of the object (e.g., 'toy', 'painting', 'sculpture'). If the input is comprised of more than a single token, you will be prompted to replace it.

In the paper, we use 5k training iterations. However, some concepts (particularly styles) can converge much faster.

To run on multiple GPUs, provide a comma-delimited list of GPU indices to the --gpus argument (e.g., --gpus 0,3,7,8)

Embeddings and output images will be saved in the log directory.

See configs/latent-diffusion/txt2img-1p4B-finetune.yaml for more options, such as changing the placeholder string which denotes the concept (defaults to "*")

Important All training set images should be upright. If you are using phone captured images, check the inputs_gs*.jpg files in the output image directory and make sure they are oriented correctly. Many phones capture images with a 90 degree rotation and denote this in the image metadata. Windows parses these correctly, but PIL does not. Hence you will need to correct them manually (e.g. by pasting them into paint and re-saving) or wait until we add metadata parsing.

Generation

To generate new images of the learned concept, run:

python scripts/txt2img.py --ddim_eta 0.0 
                          --n_samples 8 
                          --n_iter 2 
                          --scale 10.0 
                          --ddim_steps 50 
                          --embedding_path /path/to/logs/trained_model/checkpoints/embeddings_gs-5049.pt 
                          --ckpt_path /path/to/pretrained/model.ckpt 
                          --prompt "a photo of *"

where * is the placeholder string used during inversion.

Merging Checkpoints

LDM embedding checkpoints can be merged into a single file by running:

python merge_embeddings.py 
--manager_ckpts /path/to/first/embedding.pt /path/to/second/embedding.pt [...]
--output_path /path/to/output/embedding.pt

If the checkpoints contain conflicting placeholder strings, you will be prompted to select new placeholders. The merged checkpoint can later be used to prompt multiple concepts at once ("A photo of * in the style of @").

Pretrained Models / Data

Coming soon

Stable Diffusion

Stable Diffusion support is a work in progress and will be completed soon™.

Tips and Tricks

Adding "a photo of" to the prompt usually results in better target consistency.
Results can be seed sensititve. If you're unsatisfied with the model, try re-inverting with a new seed (by adding --seed <#> to the prompt).
