Stable Diffusion Textual Inversion

Copy the files into your stable-diffusion folder make it possible for text-inversion in the net UI.

In the event that you experience any problems with webui integration, please create a concern here.

In case you are having troubles installing or running textual-inversion, see FAQ below. If your trouble isn’t listed, the state repo is here.


textual-inversion – A GRAPHIC will probably be worth One Word: Personalizing Text-to-Image Generation using Textual Inversion (credit: Tel Aviv University, NVIDIA)

We figure out how to generate specific concepts, like personal objects or artistic styles, by describing them using new “words” in the embedding space of pre-trained text-to-image models. These may be used in new sentences, exactly like any word.

Essentially, this model will need some pictures of an object, style, etc. and learn to describe it in a manner that could be understood by text-to-image models such as for example Stable Diffusion. This enables one to reference specific things in your prompts, or concepts which are simpler to express with pictures instead of words.


Before you do anything with the WebUI, you need to first create an embedding file by training the Textual-Inversion model. Alternatively, you can attempt with among the pre-made embeddings from here.

In the WebUI, place the embeddings file in the embeddings file upload box. Then you can certainly reference the embedding through the use of * in your prompt.

Examples from the paper:


Training is most beneficial done utilizing the original repo

WARNING: It is a very memory-intensive model and, by writing, isn’t optimized to utilize SD. You will require an Nvidia GPU with at the very least 10GB of VRAM to even understand this to teach at all on your own local device, and a GPU with 20GB+ to teach in an acceptable period of time. If you don’t have the machine resources, you need to use Colab or stick to pretrained embeddings until SD is way better supported.

Remember that these instructions are for training on your own local device, instructions can vary greatly for trained in Colab.

You will require 3-5 images of what you need the model to spell it out. You may use more images, however the paper recommends 5. To find the best results, the images ought to be visually similar, and each image ought to be cropped to 512×512. Any sizes will undoubtedly be rescaled (stretched) and could produce strange results.


Step one 1:

Place 3-5 images of the object/artstyle/scene/etc. into a clear folder.

Step two 2: In Anaconda run

python main.py --base configs/stable-diffusion/v1-finetune.yaml -t --actual_resume models/ldm/text2img-large/model.ckpt -n --data_root path/to/image/folder --gpus 1 --init-word

–base points the script at working out configuration file

–actual_resume points the script at the Textual-Inversion model

–n provides training run a name, that may also be utilized because the output folder name.

–gpus Leave at 1 if you don’t know very well what you’re doing.

–init-word is really a single word the model begins with when considering your images for the very first time. Ought to be simple, ie: “sculpture”, “girl”, “mountains”

Step three 3:

The model will continue steadily to train and soon you stop it by entering CTRL+C. The recommended training time is 3000-7000 iterations (global steps). You can observe what step the run is on in the progress bar. You may also monitor progress by reviewing the images at logs//images. I would recommend sorting that folder by date modified, they have a tendency to get jumbled up otherwise.

Step 4:

Once stopped, you will discover several embedding files under logs//checkpoints. The main one you need is embeddings.pt.

Step 5:

In the WebUI, upload the embedding file you merely created. Now, when writing a prompt, you may use * to reference the regardless of the embedding file describes.

“An image of in the design of Rembrandt”

“An image of as a corgi”

“A coffee mug in the design of *”

  • When working with embeddings in your prompts, the authors remember that markers (*) are sensitive to puncutation. Stay away from periods or commas directly after *
  • The model will converge faster and offer more accurate results when working with language such as for example “an image of” or “as an image” in your prompts
  • When training Textual-Inversion, the paper says that using a lot more than 5 images results in less cohesive results. Some users appear to disagree. Try experimenting.
  • When training, several init-word could be specified with the addition of them to the list at initializer_words: ["sculpture", "ice"] in v1-finetune.yaml. Order may matter (unconfirmed)
  • It is possible to train multiple embedding files, then merge them with merge_embeddings.py -sd to reference multiple things. See official repo for additional information.


Q: Just how much VRAM does this require, why am I finding a CUDA Out of Memory Error?

A: This model is quite VRAM heavy, with 20GB being the recommended amount. You’ll be able to run this model on a GPU with <12GB of VRAM, but no guarantee. Try changing size: 512 to size: 448 in v1-finetune.yaml -> data: -> params: for both train: and validation: . If that’s not enough, then it’s probably far better work with a Colab notebook or other GPU hosting service to accomplish your training.


Q: Why am I finding a “SIGUSR1” error? Why am I receiving an NCNN error? Why am I receiving OSError: cannot open resource?

A: The script main.py was written without Windows at heart.

You will have to open main.py and add the next line following the last import close to the the surface of the script:

os.environ["PL_TORCH_DISTRIBUTED_BACKEND"] = "gloo"

Next, discover the following lines close to the end of the script. Change SIGUSR1 and SIGUSR2 to SIGTERM:

import signalsignal.signal(signal.SIGUSR1, melk)signal.signal(signal.SIGUSR2, divein)

Finally, open the file ldm/utils.py and discover this line: font = ImageFont.truetype('data/DejaVuSans.ttf', size=size). Comment it out and replace it with this particular: font = ImageFont.load_default()


Q: Why am I receiving one about multiple devices detected?

A: Be sure you are employing the --gpus 1 argument. In case you are still receiving the error, open main.py and discover the next lines:

or even cpu:    ngpu = len(lightning_config.trainer.gpus.strip(",").split(','))else:    ngpu = 1

Comment these lines out, then below them add ngpu = 1 (Or whatever # of GPUs you would like to use). Ensure that it really is at exactly the same indentation level because the line below it.


Q: Why am I receiving one about if trainer.global_rank == 0: ?

A: Open main.py and scroll to the finish of the file. On the previous few lines, comment out the line where it says if trainer.global_rank == 0: and the line below it.


Q: Why am I receiving errors about shapes? (IE: value tensor of shape [1280] can’t be broadcast to indexing consequence of shape [0, 768])

A: You can find two reasons for shape errors:

  • The sanity check is failing when starting Textual-Inversion training. Try leaving out the --actual-resume argument when launching main.py. It’s likely that, another error you obtain will undoubtedly be an Out of Memory Error. See earlier in the FAQ for that.
  • Stable Diffusion is erroring out once you make an effort to use an embeddings file. That is likely as you ran the Textual-Inversion training with the incorrect configuration. By writing, TI and SD aren’t integrated. Be sure you have downloaded the config/v1-finetune.yaml file out of this repo and that you utilize --base configs/stable-diffusion/v1-finetune.yaml when training embeddings. Retrain and try again.
