Organization

Participants can propose ideas for an interesting project involving diffusion models. Teams of 3 to 5 will then be formed around the most promising and interesting projects. Make sure to read through the Communication section on how to propose projects, comment on other participants' project ideas, and create a team.

To help each team successfully finish their project, we will organize talks by leading scientists and engineers from Google, Hugging Face, and the open-source diffusion community. The talks will take place on 17th of April. Make sure to attend the talks to get the most out of your participation! Check out the Talks section to get an overview of the talks, including the speaker and the time of the talk.

Each team is then given free access to a TPU v4-8 VM from April 14 to May 1st. In addition, we will provide a training example in JAX/Flax and Diffusers to train ControlNets to kick-start your project. We will also provide examples of how to prepare datasets for ControlNet training. During the sprint, we'll make sure to answer any questions you might have about JAX/Flax and Diffusers and help each team as much as possible to complete their projects!

💡 Note: We will not be distributing TPUs for single member teams, so you are encouraged to either join a team or find teammates for your idea.

At the end of the community sprint, each submission will be evaluated by a jury and the top-3 demos will be awarded a prize. Check out the [How to submit a demo] (TODO) section for more information and suggestions on how to submit your project.

💡 Note: Even though we provide an example for performing ControlNet training, participants can propose ideas that do not involve ControlNets at all. But the ideas need to be centered around diffusion models.

Data and Pre-Processing

In this section, we will cover how to build your own dataset for ControlNet training.

Prepare a large local dataset

Mount a disk

If you need extra space, you can follow this guide to create a persistent disk, attach it to your TPU VM, and create a directory to mount the disk. You can then use this directory to store your dataset.

As a side note, the TPU VM allocated to your team has a 3 TB persistent storage drive attached to it. To learn how to use it, check out this guide.

Data preprocessing

Here we demonstrate how to prepare a large dataset to train a ControlNet model with canny edge detection. More specifically, we provide an example script that:

Selects 1 million image-text pairs from an existing dataset COYO-700M.
Downloads each image and use Canny edge detector to generate the conditioning image.
Create a metafile that links all the images and processed images to their text captions.

Use the following command to run the example data preprocessing script. If you've mounted a disk to your TPU, you should place your train_data_dir and cache_dir on the mounted disk

python3 coyo_1m_dataset_preprocess.py \
 --train_data_dir="/mnt/disks/persist/data" \
 --cache_dir="/mnt/disks/persist" \
 --max_train_samples=1000000 \
 --num_proc=16

Once the script finishes running, you can find a data folder at the specified train_data_dir with the below folder structure:

data
├── images
│   ├── image_1.png
│   ├── .......
│   └── image_1000000.jpeg
├── processed_images
│   ├── image_1.png
│   ├── .......
│   └── image_1000000.jpeg
└── meta.jsonl

Load dataset

To load a dataset from the data folder you just created, you should add a dataset loading script to your data folder. The dataset loading script should have the same name as the folder. For example, if your data folder is data, you should add a data loading script named data.py. We provide an example data loading script for you to use. All you need to do is to update the DATA_DIR with the correct path to your data folder. For more details about how to write a dataset loading script, refer to the documentation.

Once the dataset loading script is added to your data folder, you can load it with:

dataset = load_dataset("/mnt/disks/persist/data", cache_dir="/mnt/disks/persist" )

Note that you can use the --train_data_dir flag to pass your data folder directory to the training script and generate your dataset automatically during the training.

For large datasets, we recommend generating the dataset once and saving it on the disk with

dataset.save_to_disk("/mnt/disks/persist/dataset")

You can then reuse the saved dataset for your training by passing the --load_from_disk flag.

Here is an example to run a training script that will load the dataset from the disk

export MODEL_DIR="runwayml/stable-diffusion-v1-5"
export OUTPUT_DIR="/mnt/disks/persist/canny_model"
export DATASET_DIR="/mnt/disks/persist/dataset"
export DISK_DIR="/mnt/disks/persist"

python3 train_controlnet_flax.py \
 --pretrained_model_name_or_path=$MODEL_DIR \
 --output_dir=$OUTPUT_DIR \
 --train_data_dir=$DATASET_DIR \
 --load_from_disk \
 --cache_dir=$DISK_DIR \
 --resolution=512 \
 --learning_rate=1e-5 \
 --train_batch_size=2 \
 --revision="non-ema" \
 --from_pt \
 --max_train_steps=500000 \
 --checkpointing_steps=10000 \
 --dataloader_num_workers=16

Prepare a dataset with MediaPipe and Hugging Face

We provide a notebook () that shows you how to prepare a dataset for ControlNet training using MediaPipe and Hugging Face. Specifically, in the notebook, we show:

How to leverage MediaPipe solutions to extract pose body joints from the input images.
Predict captions using BLIP-2 from the input images using 🤗 Transformers.
Build and push the final dataset to the Hugging Face Hub using 🤗 Datasets.

You can refer to the notebook to create your own datasets using other MediaPipe solutions as well. Below, we list all the relevant ones:

Training ControlNet

This is perhaps the most fun and interesting part of this document as here we show you how to train a custom ControlNet model.

💡 Note: For this sprint, you are NOT restricted to just training ControlNets. We provide this training script as a reference for you to get started.

For faster training on TPUs and GPUs you can leverage the Flax training example. Follow the instructions above to get the model and dataset before running the script.

Setting up your TPU VM

Before proceeding with the rest of this section, you must ensure that the email address you're using has been added to the hf-flax project on Google Cloud Platform. If it's not the case, please let us know in the Discord server (you can tag @sayakpaul, @merve, and @patrickvonplaten).

In the following, we will describe how to do so using a standard console, but you should also be able to connect to the TPU VM via IDEs, like Visual Studio Code, etc.

You need to install the Google Cloud SDK. Please follow the instructions on https://cloud.google.com/sdk.
Once you've installed the Google Cloud SDK, you should set your account by running the following command. Make sure that corresponds to the gmail address you used to sign up for this event.
```
gcloud config set account <your-email-adress>
```
Let's also make sure the correct project is set in case your email is used for multiple gcloud projects:
```
gcloud config set project hf-flax
```
Next, you will need to authenticate yourself. You can do so by running:
```
gcloud auth login
```
This should give you a link to a website, where you can authenticate your gmail account.
Finally, you can establish an SSH tunnel into the TPU VM! Please run the following command by setting--zone to us-central2-b and to the TPU name also sent to you via email from the Hugging Face team.
```
gcloud alpha compute tpus tpu-vm ssh <tpu-name> --zone <zone> --project hf-flax
```

This should establish an SSH tunnel into the TPU VM!

💡 Note: You are NOT supposed to have access to the Google Cloud console. Also, you might not get an invitation link to join the hf-flax project. But you should still be able to access the TPU VM following the above steps.

💡 Note: The TPU VMs are already attached to persistent storage drives (of 3 TB). This will be helpful in case your team wants to perform training on a large dataset locally. The disk name of the storage drive should also be present in the email you received. Follow this section for more details.

Installing JAX

Let's first create a Python virtual environment:

python3 -m venv <your-venv-name>

We can activate the environment by running:

source ~/<your-venv-name>/bin/activate

Then install Diffusers and the library's training dependencies:

pip install git+https://github.com/huggingface/diffusers.git

Then clone this repository and install JAX, Flax and the other dependencies:

git clone https://github.com/huggingface/community-events
cd community-events/jax-controlnet-sprint/training_scripts
pip install -U -r requirements_flax.txt

To verify that JAX was correctly installed, you can run the following command:

import jax
jax.device_count()

This should display the number of TPU cores, which should be 4 on a TPUv4-8 VM. If Python is not able to detect the TPU device, please take a look at this section for solutions.

If you want to use Weights and Biases logging, you should also install wandb now:

pip install wandb

💡 Note: Weights & Biases is free for students, educators, and academic researchers. All participants of our event are qualified to get an academic Weights & Biases team account. To create your team, you can visit https://wandb.ai/create-team and choose the team type to be "Academic". For more information regarding creation and management of Weights & Biases team, you can checkout https://docs.wandb.ai/guides/app/features/teams.

Running the training script

Now let's download two conditioning images that we will use to run validation during the training in order to track our progress

wget https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/controlnet_training/conditioning_image_1.png
wget https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/diffusers/controlnet_training/conditioning_image_2.png

We encourage you to store or share your model with the community. To use Hugging Face hub, please login to your Hugging Face account, or (create one if you don’t have one already):

huggingface-cli login

Make sure you have the MODEL_DIR,OUTPUT_DIR and HUB_MODEL_ID environment variables set. The OUTPUT_DIR and HUB_MODEL_ID variables specify where to save the model to on the Hub:

export MODEL_DIR="runwayml/stable-diffusion-v1-5"
export OUTPUT_DIR="runs/fill-circle-{timestamp}"
export HUB_MODEL_ID="controlnet-fill-circle"

And finally start the training (make sure you're in the jax-controlnet-sprint/training_scripts directory)!

python3 train_controlnet_flax.py \
 --pretrained_model_name_or_path=$MODEL_DIR \
 --output_dir=$OUTPUT_DIR \
 --dataset_name=fusing/fill50k \
 --resolution=512 \
 --learning_rate=1e-5 \
 --validation_image "./conditioning_image_1.png" "./conditioning_image_2.png" \
 --validation_prompt "red circle with blue background" "cyan circle with brown floral background" \
 --validation_steps=1000 \
 --train_batch_size=2 \
 --revision="non-ema" \
 --from_pt \
 --report_to="wandb" \
 --tracker_project_name=$HUB_MODEL_ID \
 --num_train_epochs=11 \
 --push_to_hub \
 --hub_model_id=$HUB_MODEL_ID

Note that --from_pt argument will convert your pytorch checkpoint into flax. However, it will only work with checkpoints in diffusers format. If your MODEL_DIR does not contain checkpoints in diffusers format, you cannot use the --from_pt argument. You can convert your ckpt or safetensors checkpoints into diffusers format using this script.

Since we passed the --push_to_hub flag, it will automatically create a model repo under your Hugging Face account based on $HUB_MODEL_ID. By the end of training, the final checkpoint will be automatically stored on the hub. You can find an example model repo here.

Our training script also provides limited support for streaming large datasets from the Hugging Face Hub. In order to enable streaming, one must also set --max_train_samples. Here is an example command (from this blog article):

export MODEL_DIR="runwayml/stable-diffusion-v1-5"
export OUTPUT_DIR="runs/uncanny-faces-{timestamp}"
export HUB_MODEL_ID="controlnet-uncanny-faces"

python3 train_controlnet_flax.py \
 --pretrained_model_name_or_path=$MODEL_DIR \
 --output_dir=$OUTPUT_DIR \
 --dataset_name=multimodalart/facesyntheticsspigacaptioned \
 --streaming \
 --conditioning_image_column=spiga_seg \
 --image_column=image \
 --caption_column=image_caption \
 --resolution=512 \
 --max_train_samples 100000 \
 --learning_rate=1e-5 \
 --train_batch_size=1 \
 --revision="flax" \
 --report_to="wandb" \
 --tracker_project_name=$HUB_MODEL_ID

Note, however, that the performance of the TPUs might get bottlenecked as streaming with datasets is not optimized for images. For ensuring maximum throughput, we encourage you to explore the following options:

When work with a larger dataset, you may need to run training process for a long time and it’s useful to save regular checkpoints during the process. You can use the following argument to enable intermediate checkpointing:

 --checkpointing_steps=500

This will save the trained model in subfolders of your output_dir. Subfolder names is the number of steps performed so far; for example: a checkpoint saved after 500 training steps would be saved in a subfolder named 500

You can then start your training from this saved checkpoint with

 --controlnet_model_name_or_path="./control_out/500"

We support training with the Min-SNR weighting strategy proposed in Efficient Diffusion Training via Min-SNR Weighting Strategy which helps to achieve faster convergence by rebalancing the loss. To use it, one needs to set the --snr_gamma argument. The recommended value when using it is 5.0.

We also support gradient accumulation - it is a technique that lets you use a bigger batch size than your machine would normally be able to fit into memory. You can use gradient_accumulation_steps argument to set gradient accumulation steps. The ControlNet author recommends using gradient accumulation to achieve better convergence. Read more here.

You can profile your code with:

 --profile_steps==5

Refer to the JAX documentation on profiling. To inspect the profile trace, you'll have to install and start Tensorboard with the profile plugin:

pip install tensorflow tensorboard-plugin-profile
tensorboard --logdir runs/fill-circle-100steps-20230411_165612/

The profile can then be inspected at http://localhost:6006/#profile

Sometimes you'll get version conflicts (error messages like Duplicate plugins for name projector), which means that you have to uninstall and reinstall all versions of Tensorflow/Tensorboard (e.g. with pip uninstall tensorflow tf-nightly tensorboard tb-nightly tensorboard-plugin-profile && pip install tf-nightly tbp-nightly tensorboard-plugin-profile).

Note that the debugging functionality of the Tensorboard profile plugin is still under active development. Not all views are fully functional, and for example the trace_viewer cuts off events after 1M (which can result in all your device traces getting lost if you for example profile the compilation step by accident).

Troubleshoot your TPU VM

VERY IMPORTANT - Only one process can access the TPU cores at a time. This means that if multiple team members are trying to connect to the TPU cores, you will get errors such as:

libtpu.so already in used by another process. Not attempting to load libtpu.so in this process.

We recommend every team member create her/his own virtual environment, but only one person should run the heavy training processes. Also, please take turns when setting up the TPUv4-8 so that everybody can verify that JAX is correctly installed.

If your team members are not currently using the TPU but you still get this error message. You should kill the process that is using the TPU with

kill -9 PID

you will need to replace the term “PID” with the PID of the process that uses TPU. In most cases, this information is included in the error message. For example, if you get

The TPU is already in use by a process with pid 1378725. Not attempting to load libtpu.so in this process.

you can do

kill -9 1378725

You can also use the below command to find processes using each of the TPU chips (e.g. /dev/accel0 is one of the TPU chips)

sudo lsof -w /dev/accel0

To kill all the processes using /dev/accel0

sudo lsof -t /dev/accel0 | xargs kill -9

If Python is not able to detect your TPU device (i.e. when you do jax.device_count() and it outputs 0), it might be because you have no rights to access the tpu logs, or you have a dangling tpu lock file. Run these commands usually fix the issue

sudo rm -f /tmp/libtpu_lockfile

sudo chmod o+w /tmp/tpu_logs/

How to Make a Submission

To make a full submission, you need to have the following on Hugging Face Hub:

Model repository with model weights and model card,
(Optional) Dataset repository with dataset card,
A Hugging Face Space that lets others interact with your model.

Pushing model weights and the model card to Hub

If you are using the training script (train_controlnet_flax.py) provided in this directory

Enabling push_to_hub argument in the training arguments will:

Create a model repository locally, and remotely on Hugging Face Hub,
Create a model card and write it to the local model repository,
Save your model to the local model repository,
Push the local repository to Hugging Face Hub.

Your automatically generated model card will look like below 👇 .

You can edit the model card to be more informative. Model cards that are more informative than the others will carry more weight during evaluation.

If you have trained a custom model and not used the script

You need to authenticate yourself with huggingface-cli login as instructed above. If you are using one of the available model classes from diffusers, save your model with save_pretrained method of your model.

model.save_pretrained("path_to_your_model_repository")

After saving your model to a folder, you can simply use below script to push your model to the Hub 👇

from huggingface_hub import create_repo, upload_folder

create_repo("username/my-awesome-model")
upload_folder(
    folder_path="path_to_your_model_repository",
    repo_id="username/my-awesome-model"
)

This will push your model to Hub. After pushing your model to Hub, you need to create the model card yourself. You can use graphical interface to edit the model card.

Every model card consists of two sections, metadata and free text. You can edit metadata from the sections in graphical UI. If you have saved your model using `save_pretrained`, you do not need to provide `pipeline_tag` and `library_name`. If not, provide `pipeline_tag`, `library_name` and dataset if it exists on Hugging Face Hub. Aside from these, you need to add the `jax-diffusers-event` to `tags` section. ```

![Edit Metadata](https://huggingface.co/datasets/huggingface/documentation-images/resolve/main/edit_metadata.png)

### Creating our Space

<h4> Writing our Application </h4>

    
We will use [Gradio](https://gradio.app/) to build our applications. Gradio has two main APIs: `Interface` and `Blocks`. `Interface` is a high-level API that lets you create an interface with few lines of code, and `Blocks` is a lower-level API that gives you more flexibility over interfaces you can build. The code should be included in a file called `app.py`.

Let's try to create a ControlNet app as an example. The `Interface` API simply works like below 👇 

```python
import gradio as gr

# inference function takes prompt, negative prompt and image
def infer(prompt, negative_prompt, image):
    # implement your inference function here
    return output_image

# you need to pass inputs and outputs according to inference function
gr.Interface(fn = infer, inputs = ["text", "text", "image"], outputs = "image").launch()

You can customize your interface by passing title, description and examples to the Interface function.

title = "ControlNet on Canny Filter"
description = "This is a demo on ControlNet based on canny filter."
# you need to pass your examples according to your inputs
# each inner list is one example, each element in the list corresponding to a component in the `inputs`.
examples = [["a cat with cake texture", "low quality", "cat_image.png"]]
gr.Interface(fn = infer, inputs = ["text", "text", "image"], outputs = "image",
            title = title, description = description, examples = examples, theme='gradio/soft').launch()

Your interface will look like below 👇

With Blocks, you can add markdown, tabs, components under columns and rows and more. Assume we have two ControlNets and we want to include them in one Space. We will have them under different tabs under one demo like below 👇

import gradio as gr

def infer_segmentation(prompt, negative_prompt, image):
    # your inference function for segmentation control 
    return im

def infer_canny(prompt, negative_prompt, image):
    # your inference function for canny control 
    return im

with gr.Blocks(theme='gradio/soft') as demo:
    gr.Markdown("## Stable Diffusion with Different Controls")
    gr.Markdown("In this app, you can find different ControlNets with different filters. ")


    with gr.Tab("ControlNet on Canny Filter "):
        prompt_input_canny = gr.Textbox(label="Prompt")
        negative_prompt_canny = gr.Textbox(label="Negative Prompt")
        canny_input = gr.Image(label="Input Image")
        canny_output = gr.Image(label="Output Image")
        submit_btn = gr.Button(value = "Submit")
        canny_inputs = [prompt_input_canny, negative_prompt_canny, canny_input]
        submit_btn.click(fn=infer_canny, inputs=canny_inputs, outputs=[canny_output])
        
    with gr.Tab("ControlNet with Semantic Segmentation"):
        prompt_input_seg = gr.Textbox(label="Prompt")
        negative_prompt_seg = gr.Textbox(label="Negative Prompt")
        seg_input = gr.Image(label="Image")
        seg_output = gr.Image(label="Output Image")
        submit_btn = gr.Button(value = "Submit")
        seg_inputs = [prompt_input_seg, negative_prompt_seg, seg_input]
        submit_btn.click(fn=infer_segmentation, inputs=seg_inputs, outputs=[seg_output])

demo.launch()

Above demo will look like below 👇

Creating our Space

After our application is written, we can create a Hugging Face Space to host our app. You can go to huggingface.co, click on your profile on top right and select “New Space”.

We can name our Space, pick a license and select Space SDK as “Gradio”.

After creating the Space, you can either use the instructions below to clone the repository locally, add your files and push, or use the graphical interface to create the files and write the code in the browser.

To upload your application file, pick “Add File” and drag and drop your file.

Lastly, we have to create a file called requirements.txt and add requirements of our project. Make sure to install below versions of jax, diffusers and other dependencies like below.

-f https://storage.googleapis.com/jax-releases/jax_cuda_releases.html
jax[cuda11_cudnn805]
jaxlib
git+https://github.com/huggingface/diffusers@main
opencv-python
transformers
flax

We will give you GPU grant so your application can run on GPU.

We have a leaderboard hosted here and we will be distributing prizes from this leaderboard. To make your Space show up on the leaderboard, simply edit `README.md` of your Space to have the tag `jax-diffusers-event` under tags like below 👇 ```

title: Canny Coyo1m emoji: 💜 ... tags: - jax-diffusers-event


## Prizes

For this sprint we will have many prizes. We will pick the first ten projects from [this leaderboard](https://huggingface.co/spaces/jax-diffusers-event/leaderboard), so you should tag your Space for the leaderboard to make your submission complete, as instructed in above section. The projects are ranked by likes, so we will amplify the visibility of all projects for people to cast their votes by leaving a like on the Space. We will pick the first ten projects from the ranking, and the jury will cast their votes to determine the first three places. These projects will be highlighted by both Google and Hugging Face. Elaborately made interfaces as well as projects with open-sourced codebases and models will likely increase the chance of winning prizes. 

Prizes are as follows and are given to each team member 👇 
    
**First Place**: A voucher of $150 that you can spend at [Hugging Face Store](https://store.huggingface.co/), Hugging Face Hub PRO subscription for one year, Natural Language Processing with Transformers book
    
**Second Place**: A voucher of $125 that you can spend at [Hugging Face Store](https://store.huggingface.co/), Hugging Face Hub PRO subscription for one year

## FAQ 

In this section, We are collecting answers to frequently asked questions from our discord channel. Contributions welcome!

### How to Use VSCode with TPU VM?

You can follow this [general guide](https://medium.com/@ivanzhd/vscode-sftp-connection-to-compute-engine-on-google-cloud-platform-gcloud-9312797d56eb) on how to use VSCode remote to connect to Google Cloud VMs. Once it's set up, you can develop on the TPU VM using VSCode.

To get your external IP, use this command:

gcloud compute tpus tpu-vm describe --zone=


It should be listed under 'accessConfig' -> 'externalIp'

### How to Test Your Code Locally?

Since team members are sharing the TPU VM, it might be practical to write and test your code locally on a CPU while your teammates are running the training process on the VM. To run local testing, it is important to set the `xla_force_host_platform_device_count` flag to `4`. Read more on the [documentation](https://jax.readthedocs.io/en/latest/jax-101/06-parallelism.html#aside-hosts-and-devices-in-jax).
    
## Sprint winners
    
Top 10 projects (based on the likes on their demo applications) are available on this [leaderboard](https://huggingface.co/spaces/jax-diffusers-event/leaderboard). We tooks this leaderboard to our [jury](#jury) to judge the top 10 projects based on several factors such as open-source model checkpoints, datasets, and codebases, completeness of the model and dataset cards, etc. As a result, following three projects emerged as the winners:
    
1. [ControlNet for Interior Design](https://huggingface.co/spaces/controlnet-interior-design/controlnet-seg)
2. [ControlNet for Adjusting Brightness](https://huggingface.co/spaces/ioclab/brightness-controlnet)
3. [Stable Diffusion with Hand Control](https://huggingface.co/spaces/vllab/controlnet-hands)
