*We present ControlNet, a neural network architecture to add spatial conditioning controls to large, pretrained text-to-image diffusion models. ControlNet locks the production-ready large diffusion models, and reuses their deep and robust encoding layers pretrained with billions of images as a strong backbone to learn a diverse set of conditional controls. The neural architecture is connected with "zero convolutions" (zero-initialized convolution layers) that progressively grow the parameters from zero and ensure that no harmful noise could affect the finetuning. We test various conditioning controls, eg, edges, depth, segmentation, human pose, etc, with Stable Diffusion, using single or multiple conditions, with or without prompts. We show that the training of ControlNets is robust with small (<50k) and large (>1m) datasets. Extensive results show that ControlNet may facilitate wider applications to control image diffusion models.*

*Recent studies have demonstrated that diffusion models are capable of generating high-quality samples, but their quality heavily depends on sampling guidance techniques, such as classifier guidance (CG) and classifier-free guidance (CFG). These techniques are often not applicable in unconditional generation or in various downstream tasks such as image restoration. In this paper, we propose a novel sampling guidance, called Perturbed-Attention Guidance (PAG), which improves diffusion sample quality across both unconditional and conditional settings, achieving this without requiring additional training or the integration of external modules. PAG is designed to progressively enhance the structure of samples throughout the denoising process. It involves generating intermediate samples with degraded structure by substituting selected self-attention maps in diffusion U-Net with an identity matrix, by considering the self-attention mechanisms' ability to capture structural information, and guiding the denoising process away from these degraded samples. In both ADM and Stable Diffusion, PAG surprisingly improves sample quality in conditional and even unconditional scenarios. Moreover, PAG significantly improves the baseline performance in various downstream tasks where existing guidances such as CG or CFG cannot be fully utilized, including ControlNet with empty prompts and image restoration such as inpainting and deblurring.*

PAG can be used by specifying the `pag_applied_layers` as a parameter when instantiating a PAG pipeline. It can be a single string or a list of strings. Each string can be a unique layer identifier or a regular expression to identify one or more layers.

*Open generative models are vitally important for the community, allowing for fine-tunes and serving as baselines when presenting new models. However, most current text-to-audio models are private and not accessible for artists and researchers to build upon. Here we describe the architecture and training process of a new open-weights text-to-audio model trained with Creative Commons data. Our evaluation shows that the model's performance is competitive with the state-of-the-art across various metrics. Notably, the reported FDopenl3 results (measuring the realism of the generations) showcase its potential for high-quality stereo sound synthesis at 44.1kHz.*

This works by merging multiple LoRA weights together to produce images that are a blend of different styles. Diffusers provides a few methods to merge LoRAs depending on *how* you want to merge their weights, which can affect image quality.

# DreamBooth training example for FLUX.1 [dev]
|
||||
|
||||
[DreamBooth](https://arxiv.org/abs/2208.12242) is a method to personalize text2image models like stable diffusion given just a few (3~5) images of a subject.
|
||||
|
||||
The `train_dreambooth_flux.py` script shows how to implement the training procedure and adapt it for [FLUX.1 [dev]](https://blackforestlabs.ai/announcing-black-forest-labs/). We also provide a LoRA implementation in the `train_dreambooth_lora_flux.py` script.
|
||||
> [!NOTE]
|
||||
> **Memory consumption**
|
||||
>
|
||||
> Flux can be quite expensive to run on consumer hardware devices and as a result finetuning it comes with high memory requirements -
|
||||
> a LoRA with a rank of 16 (w/ all components trained) can exceed 40GB of VRAM for training.
|
||||
> For more tips & guidance on training on a resource-constrained device please visit [`@bghira`'s guide](https://github.com/bghira/SimpleTuner/blob/main/documentation/quickstart/FLUX.md)
|
||||
|
||||
|
||||
> [!NOTE]
|
||||
> **Gated model**
|
||||
>
|
||||
> As the model is gated, before using it with diffusers you first need to go to the [FLUX.1 [dev] Hugging Face page](https://huggingface.co/black-forest-labs/FLUX.1-dev), fill in the form and accept the gate. Once you are in, you need to log in so that your system knows you’ve accepted the gate. Use the command below to log in:
|
||||
|
||||
```bash
|
||||
huggingface-cli login
|
||||
```
|
||||
|
||||
This will also allow us to push the trained model parameters to the Hugging Face Hub platform.
|
||||
|
||||
## Running locally with PyTorch
|
||||
|
||||
### Installing the dependencies
|
||||
|
||||
Before running the scripts, make sure to install the library's training dependencies:
|
||||
|
||||
**Important**
|
||||
|
||||
To make sure you can successfully run the latest versions of the example scripts, we highly recommend **installing from source** and keeping the install up to date as we update the example scripts frequently and install some example-specific requirements. To do this, execute the following steps in a new virtual environment:
|
||||
|
||||
```bash
|
||||
git clone https://github.com/huggingface/diffusers
|
||||
cd diffusers
|
||||
pip install -e .
|
||||
```
|
||||
|
||||
Then cd in the `examples/dreambooth` folder and run
|
||||
```bash
|
||||
pip install -r requirements_flux.txt
|
||||
```
|
||||
|
||||
And initialize an [🤗Accelerate](https://github.com/huggingface/accelerate/) environment with:
|
||||
|
||||
```bash
|
||||
accelerate config
|
||||
```
|
||||
|
||||
Or for a default accelerate configuration without answering questions about your environment
|
||||
|
||||
```bash
|
||||
accelerate config default
|
||||
```
|
||||
|
||||
Or if your environment doesn't support an interactive shell (e.g., a notebook)
|
||||
|
||||
```python
|
||||
from accelerate.utils import write_basic_config
|
||||
write_basic_config()
|
||||
```
|
||||
|
||||
When running `accelerate config`, if we specify torch compile mode to True there can be dramatic speedups.
|
||||
Note also that we use PEFT library as backend for LoRA training, make sure to have `peft>=0.6.0` installed in your environment.
|
||||
|
||||

### Dog toy example
|
||||
|
||||
Now let's get our dataset. For this example we will use some dog images: https://huggingface.co/datasets/diffusers/dog-example.
|
||||
|
||||
Let's first download it locally:
|
||||
|
||||
```python
|
||||
from huggingface_hub import snapshot_download
|
||||
|
||||
local_dir = "./dog"
|
||||
snapshot_download(
|
||||
"diffusers/dog-example",
|
||||
local_dir=local_dir, repo_type="dataset",
|
||||
ignore_patterns=".gitattributes",
|
||||
)
|
||||
```
|
||||
|
||||
This will also allow us to push the trained LoRA parameters to the Hugging Face Hub platform.
|
||||
|
||||
Now, we can launch training using:
|
||||
|
||||
```bash
|
||||
export MODEL_NAME="black-forest-labs/FLUX.1-dev"
|
||||
export INSTANCE_DIR="dog"
|
||||
export OUTPUT_DIR="trained-flux"
|
||||
|
||||
accelerate launch train_dreambooth_flux.py \
|
||||
--pretrained_model_name_or_path=$MODEL_NAME \
|
||||
--instance_data_dir=$INSTANCE_DIR \
|
||||
--output_dir=$OUTPUT_DIR \
|
||||
--mixed_precision="bf16" \
|
||||
--instance_prompt="a photo of sks dog" \
|
||||
--resolution=1024 \
|
||||
--train_batch_size=1 \
|
||||
--gradient_accumulation_steps=4 \
|
||||
--learning_rate=1e-4 \
|
||||
--report_to="wandb" \
|
||||
--lr_scheduler="constant" \
|
||||
--lr_warmup_steps=0 \
|
||||
--max_train_steps=500 \
|
||||
--validation_prompt="A photo of sks dog in a bucket" \
|
||||
--validation_epochs=25 \
|
||||
--seed="0" \
|
||||
--push_to_hub
|
||||
```
|
||||
|
||||
To better track our training experiments, we're using the following flags in the command above:
|
||||
|
||||
* `report_to="wandb` will ensure the training runs are tracked on Weights and Biases. To use it, be sure to install `wandb` with `pip install wandb`.
|
||||
* `validation_prompt` and `validation_epochs` to allow the script to do a few validation inference runs. This allows us to qualitatively check if the training is progressing as expected.
|
||||
|
||||
> [!NOTE]
|
||||
> If you want to train using long prompts with the T5 text encoder, you can use `--max_sequence_length` to set the token limit. The default is 77, but it can be increased to as high as 512. Note that this will use more resources and may slow down the training in some cases.
|
||||
|
||||
> [!TIP]
|
||||
> You can pass `--use_8bit_adam` to reduce the memory requirements of training. Make sure to install `bitsandbytes` if you want to do so.
|
||||
|
||||
## LoRA + DreamBooth
|
||||
|
||||
[LoRA](https://huggingface.co/docs/peft/conceptual_guides/adapter#low-rank-adaptation-lora) is a popular parameter-efficient fine-tuning technique that allows you to achieve full-finetuning like performance but with a fraction of learnable parameters.
|
||||
|
||||
Note also that we use PEFT library as backend for LoRA training, make sure to have `peft>=0.6.0` installed in your environment.
|
||||
|
||||
To perform DreamBooth with LoRA, run:
|
||||
|
||||
```bash
|
||||
export MODEL_NAME="black-forest-labs/FLUX.1-dev"
|
||||
export INSTANCE_DIR="dog"
|
||||
export OUTPUT_DIR="trained-flux-lora"
|
||||
|
||||
accelerate launch train_dreambooth_lora_flux.py \
|
||||
--pretrained_model_name_or_path=$MODEL_NAME \
|
||||
--instance_data_dir=$INSTANCE_DIR \
|
||||
--output_dir=$OUTPUT_DIR \
|
||||
--mixed_precision="bf16" \
|
||||
--instance_prompt="a photo of sks dog" \
|
||||
--resolution=512 \
|
||||
--train_batch_size=1 \
|
||||
--gradient_accumulation_steps=4 \
|
||||
--learning_rate=1e-5 \
|
||||
--report_to="wandb" \
|
||||
--lr_scheduler="constant" \
|
||||
--lr_warmup_steps=0 \
|
||||
--max_train_steps=500 \
|
||||
--validation_prompt="A photo of sks dog in a bucket" \
|
||||
--validation_epochs=25 \
|
||||
--seed="0" \
|
||||
--push_to_hub
|
||||
```
|
||||
|
||||
### Text Encoder Training
|
||||
|
||||
Alongside the transformer, fine-tuning of the CLIP text encoder is also supported.
|
||||
To do so, just specify `--train_text_encoder` while launching training. Please keep the following points in mind:
|
||||
|
||||
> [!NOTE]
|
||||
> FLUX.1 has 2 text encoders (CLIP L/14 and T5-v1.1-XXL).
|
||||
By enabling `--train_text_encoder`, fine-tuning of the **CLIP encoder** is performed.
|
||||
> At the moment, T5 fine-tuning is not supported and weights remain frozen when text encoder training is enabled.
|
||||
|
||||
To perform DreamBooth LoRA with text-encoder training, run:
|
||||
```bash
|
||||
export MODEL_NAME="black-forest-labs/FLUX.1-dev"
|
||||
export OUTPUT_DIR="trained-flux-dev-dreambooth-lora"
|
||||
|
||||
accelerate launch train_dreambooth_lora_flux.py \
|
||||
--pretrained_model_name_or_path=$MODEL_NAME \
|
||||
--instance_data_dir=$INSTANCE_DIR \
|
||||
--output_dir=$OUTPUT_DIR \
|
||||
--mixed_precision="bf16" \
|
||||
--train_text_encoder\
|
||||
--instance_prompt="a photo of sks dog" \
|
||||
--resolution=512 \
|
||||
--train_batch_size=1 \
|
||||
--gradient_accumulation_steps=4 \
|
||||
--learning_rate=1e-5 \
|
||||
--report_to="wandb" \
|
||||
--lr_scheduler="constant" \
|
||||
--lr_warmup_steps=0 \
|
||||
--max_train_steps=500 \
|
||||
--validation_prompt="A photo of sks dog in a bucket" \
|
||||
--seed="0" \
|
||||
--push_to_hub
|
||||
```

Once you have trained a model using above command, the inference can be done simply using the `StableDiffusionXLPipeline`.
|

Make sure to include the `placeholder_token` in your prompt.

```python
|

from diffusers import StableDiffusionXLPipeline
|

r"""
|
||||
Function invoked when calling the pipeline for generation.
|
||||
|
||||
Args:
|
||||
prompt (`str` or `List[str]`, *optional*):
|
||||
The prompt or prompts to guide the image generation. If not defined, one has to pass `prompt_embeds`.
|
||||
instead.
|
||||
prompt_2 (`str` or `List[str]`, *optional*):
|
||||
The prompt or prompts to be sent to `tokenizer_2` and `text_encoder_2`. If not defined, `prompt` is
|
||||
will be used instead
|
||||
height (`int`, *optional*, defaults to self.unet.config.sample_size * self.vae_scale_factor):
|
||||
The height in pixels of the generated image. This is set to 1024 by default for the best results.
|
||||
width (`int`, *optional*, defaults to self.unet.config.sample_size * self.vae_scale_factor):
|
||||
The width in pixels of the generated image. This is set to 1024 by default for the best results.
|
||||
num_inference_steps (`int`, *optional*, defaults to 50):
|
||||
The number of denoising steps. More denoising steps usually lead to a higher quality image at the
|
||||
expense of slower inference.
|
||||
timesteps (`List[int]`, *optional*):
|
||||
Custom timesteps to use for the denoising process with schedulers which support a `timesteps` argument
|
||||
in their `set_timesteps` method. If not defined, the default behavior when `num_inference_steps` is
|
||||
passed will be used. Must be in descending order.
|
||||
guidance_scale (`float`, *optional*, defaults to 7.0):
|
||||
Guidance scale as defined in [Classifier-Free Diffusion Guidance](https://arxiv.org/abs/2207.12598).
|
||||
`guidance_scale` is defined as `w` of equation 2. of [Imagen
|
||||
Paper](https://arxiv.org/pdf/2205.11487.pdf). Guidance scale is enabled by setting `guidance_scale >
|
||||
1`. Higher guidance scale encourages to generate images that are closely linked to the text `prompt`,
|
||||
usually at the expense of lower image quality.
|
||||
num_images_per_prompt (`int`, *optional*, defaults to 1):
|
||||
The number of images to generate per prompt.
|
||||
generator (`torch.Generator` or `List[torch.Generator]`, *optional*):
|
||||
One or a list of [torch generator(s)](https://pytorch.org/docs/stable/generated/torch.Generator.html)
|
||||
to make generation deterministic.
|
||||
latents (`torch.FloatTensor`, *optional*):
|
||||
Pre-generated noisy latents, sampled from a Gaussian distribution, to be used as inputs for image
|
||||
generation. Can be used to tweak the same generation with different prompts. If not provided, a latents
|
||||
tensor will ge generated by sampling using the supplied random `generator`.
|
||||
prompt_embeds (`torch.FloatTensor`, *optional*):
|
||||
Pre-generated text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting. If not
|
||||
provided, text embeddings will be generated from `prompt` input argument.
|
||||
pooled_prompt_embeds (`torch.FloatTensor`, *optional*):
|
||||
Pre-generated pooled text embeddings. Can be used to easily tweak text inputs, *e.g.* prompt weighting.
|
||||
If not provided, pooled text embeddings will be generated from `prompt` input argument.
|
||||
output_type (`str`, *optional*, defaults to `"pil"`):
|
||||
The output format of the generate image. Choose between
|
||||
[PIL](https://pillow.readthedocs.io/en/stable/): `PIL.Image.Image` or `np.array`.
|
||||
return_dict (`bool`, *optional*, defaults to `True`):
|
||||
Whether or not to return a [`~pipelines.flux.FluxPipelineOutput`] instead of a plain tuple.
|
||||
joint_attention_kwargs (`dict`, *optional*):
|
||||
A kwargs dictionary that if specified is passed along to the `AttentionProcessor` as defined under
|
||||
`self.processor` in
|
||||
[diffusers.models.attention_processor](https://github.com/huggingface/diffusers/blob/main/src/diffusers/models/attention_processor.py).
|
||||
callback_on_step_end (`Callable`, *optional*):
|
||||
A function that calls at the end of each denoising steps during the inference. The function is called
|
||||
with the following arguments: `callback_on_step_end(self: DiffusionPipeline, step: int, timestep: int,
|
||||
callback_kwargs: Dict)`. `callback_kwargs` will include a list of all tensors as specified by
|
||||
`callback_on_step_end_tensor_inputs`.
|
||||
callback_on_step_end_tensor_inputs (`List`, *optional*):
|
||||
The list of tensor inputs for the `callback_on_step_end` function. The tensors specified in the list
|
||||
will be passed as `callback_kwargs` argument. You will only be able to include variables listed in the
|
||||
`._callback_tensor_inputs` attribute of your pipeline class.
|
||||
max_sequence_length (`int` defaults to 512): Maximum sequence length to use with the `prompt`.
|
||||
|
||||
Examples:
|
||||
|
||||
Returns:
|
||||
[`~pipelines.flux.FluxPipelineOutput`] or `tuple`: [`~pipelines.flux.FluxPipelineOutput`] if `return_dict`
|
||||
is True, otherwise a `tuple`. When returning a tuple, the first element is a list with the generated
|
||||
images.
