Stable Diffusion Dreambooth (Finetuning)

stars - badge-generator

Introduction

Stable diffusion has revolutionalized text2image models by producing high quality images based on a prompt. Dreambooth is a approach for personalization of text-to-image diffusion models. With images as input subject, we can fine-tune a pretrained text-to-image model

Although the dreambooth paper used Imagen to finetune the pre-trained model since both the Imagen model and Dreambooth code are closed source, several opensource projects have emerged using stable diffusion.

Dreambooth makes stable-diffusion even more powered with the ability to generate realistic looking pictures of humans, animals or any other object by just training them on 20-30 images.

In this example tutorial, we will be fine-tuning a pretrained stable diffusion using images of a human and generating images of him drinking coffee.

TD;LR

The following command generates the following:

  • Subject: SBF
  • Prompt: a photo of SBF without hair
bacalhau docker run \
--gpu 1 \
--timeout 3600 \
--wait-timeout-secs 3600 \
-i ipfs://QmRKnvqvpFzLjEoeeNNGHtc7H8fCn9TvNWHFnbBHkK8Mhy \
jsacex/dreambooth:full \
-- bash finetune.sh /inputs /outputs "a photo of sbf man" "a photo of man" 3000 "/man" "/model"

Inference

bacalhau docker run \
--gpu 1 \
-i ipfs://QmUEJPr5pfV6tRzWQuNSSb3wdcN6tRQS5tdk3dYSCJ55Xs:/SBF.ckpt \
jsacex/stable-diffusion-ckpt \
-- conda run --no-capture-output -n ldm python scripts/txt2img.py --prompt "a photo of sbf without hair" --plms --ckpt ../SBF.ckpt --skip_grid --n_samples 1 --skip_grid --outdir ../outputs

Output:

Prerequisites

To get started, you need to install the Bacalhau client, see more information here

Setting up Docker Container

info

You can skip this section entirely and directly go to running a job on Bacalhau

Building this container requires you to have a supported GPU which needs to have 16gb+ of memory, since it can be resource intensive.

We will create a Dockerfile and add the desired configuration to the file. These commands specify how the image will be built, and what extra requirements will be included.

echo model saved at $2/model.ckpt

The shell script is there to make things much simpler since the command to train the model needs many parameters to pass and later convert the model weights to the checkpoint, you can edit this script and add in your own parameters

Build the Docker container

We will run docker build command to build the container;

docker build -t <hub-user>/<repo-name>:<tag> .

Before running the command replace;

  • hub-user with your docker hub username, If you don’t have a docker hub account follow these instructions to create a Docker account, and use the username of the account you created

  • repo-name with the name of the container, you can name it anything you want

  • tag this is not required but you can use the latest tag

Now you can push this repository to the registry designated by its name or tag.

docker push <hub-user>/<repo-name>:<tag>

Create the Subject Dataset

The optimal dataset size is between 20-30 images. You can choose the images of the subject in different positions, full body images, half body, pictures of the face etc.

Only the subject should appear in the image so you can crop the image to just fit the subject. Make sure that the images are 512x512 size and are named in the following pattern since the subject name is David Aronchick we name the images in the following pattern

David Aronchick.jpg, David Aronchick (2).jpg ... David Aronchick (n).jpg

You can view the Subject Image dataset of David Aronchick for reference

After the Subject dataset is created we upload it to IPFS

Uploading the Subject Images to IPFS

In this case, we will be using NFT.Storage (Recommended Option) to upload files and directories with NFTUp

To upload your dataset using NFTup just drag and drop your directory it will upload it to IPFS

After the checkpoint file has been uploaded copy its CID bafybeidqbuphwkqwgrobv2vakwsh3l6b4q2mx7xspgh4l7lhulhc3dfa7a

Approaches to run a Bacalhau Job on a Finetuned Model

Since there are a lot of combinations that you can try, processing of finetuned model can take almost 1hr+ to complete. Here are a few approaches that you can try based on your requirements

Case0 If the subject is of class male

bacalhau docker run \
--gpu 1 \
--timeout 3600 \
--wait-timeout-secs 3600 \
--timeout 3600 \
--wait-timeout-secs 3600 \
-i <CID-OF-THE-SUBJECT> \
jsacex/dreambooth:full \
-- bash finetune.sh /inputs /outputs "a photo of <name-of-the-subject> man" "a photo of man" 3000 "/man" "/model"

Structure of the command

  • No of GPUs --gpu 1

  • CID of the Subject Images -i ipfs://bafybeidqbuphwkqwgrobv2vakwsh3l6b4q2mx7xspgh4l7lhulhc3dfa7a

  • Name of our Image jsacex/dreambooth:latest

-- bash finetune.sh /inputs /outputs "a photo of aronchick man" "a photo of man" 3000 "/man"

  • Path to the subject Images /inputs

  • Path to save the generated outputs /outputs

  • Subject name along with class "a photo of < name of the subject > < class >" -> "a photo of aronchick man"

  • Name of the class "a photo of < class >" -> "a photo of man"

The number of iterations is 3000. This number should be no of subject images x 100. So if there are 30 images, it would be 3000. It takes around 32Mins on a v100 for 3000 iterations, but you can increase/decrease the number based on your requirements

Path to our class Images /man

Here is our command with our parameters replaced

%%bash --out job_id
bacalhau docker run \
--gpu 1 \
--timeout 3600 \
--wait-timeout-secs 3600 \
--timeout 3600 \
--wait-timeout-secs 3600 \
-i ipfs://bafybeidqbuphwkqwgrobv2vakwsh3l6b4q2mx7xspgh4l7lhulhc3dfa7a \
--wait \
--id-only \
jsacex/dreambooth:full \
-- bash finetune.sh /inputs /outputs "a photo of aronchick man" "a photo of man" 3000 "/man" "/model"

If your subject fits the above class but has a different name you just need to replace the input CID and the subject name which in this case is SBF

 bacalhau docker run \
--gpu 1 \
-i ipfs://QmRKnvqvpFzLjEoeeNNGHtc7H8fCn9TvNWHFnbBHkK8Mhy \
jsacex/dreambooth:full \
-- bash finetune.sh /inputs /outputs "a photo of sbf man" "a photo of man" 3000 "/man" "/model"

Case1 If the subject is of class female

Use the /woman class images

bacalhau docker run \
--gpu 1 \
--timeout 3600 \
--wait-timeout-secs 3600 \
-i <CID-OF-THE-SUBJECT> \
jsacex/dreambooth:full \
-- bash finetune.sh /inputs /outputs "a photo of <name-of-the-subject> woman" "a photo of woman" 3000 "/woman" "/model"

Case2 If the subject is of class mix

provide your own regularization images or use the mix class

Use the /mix class images if the class of the subject is mix

bacalhau docker run \
--gpu 1 \
--timeout 3600 \
--wait-timeout-secs 3600 \
-i <CID-OF-THE-SUBJECT> \
jsacex/dreambooth:full \
-- bash finetune.sh /inputs /outputs "a photo of <name-of-the-subject> mix" "a photo of mix" 3000 "/mix" "/model"

Case3 If you want a different tokenizer, model, and a different shell script with custom parameters

You can upload the model to IPFS and then create a gist and mount the model and script to the lightweight container

bacalhau docker run \
--gpu 1 \
--timeout 3600 \
--wait-timeout-secs 3600 \
-i ipfs://bafybeidqbuphwkqwgrobv2vakwsh3l6b4q2mx7xspgh4l7lhulhc3dfa7a:/aronchick \
-i ipfs://<CID-OF-THE-MODEL>:/model
-i https://gist.githubusercontent.com/js-ts/54b270a36aa3c35fdc270640680b3bd4/raw/7d8e8fa47bc3811ef63772f7fc7f4360aa9d51a8/finetune.sh
--wait \
--id-only \
jsacex/dreambooth:lite \
-- bash /inputs/finetune.sh /aronchick /outputs "a photo of aronchick man" "a photo of man" 3000 "/man" "/model"

When a job is submitted, Bacalhau prints out the related job_id. We store that in an environment variable so that we can reuse it later on.

Checking the State of your Jobs

  • Job status: You can check the status of the job using bacalhau list.
%%bash
bacalhau list --id-filter ${JOB_ID} --wide

 CREATED  ID  JOB  STATE  VERIFIED  PUBLISHED   22-11-14-07:16:17  9fcd210b-bc8a-4f38-bf5e-5ac39e0b8be4  Docker jsacex/dreambooth:latest bash finetune.sh /inputs /outputs a photo of aronchick man a photo of man 3000 /man  Completed   /ipfs/QmcmD7M7pYLP8QgwjqpbP4dojRLiLuEBdhevuCD9kFmbdV 

When it says Published or Completed, that means the job is done, and we can get the results.

  • Job information: You can find out more information about your job by using bacalhau describe.
%%bash
bacalhau describe ${JOB_ID}

In the next steps, we will be doing inference on the finetuned model

Inference on the Fine-Tuned Model

info

Refer https://docs.bacalhau.org/examples/model-inference/Stable-Diffusion-CKPT-Inference on details of how to build a SD inference container

Bacalhau currently doesn't support mounting subpaths of the CID, so instead of just mounting the model.ckpt file we need to mount the whole output CID which is 6.4GB, which might result in errors like FAILED TO COPY /inputs. So you have to manually copy the CID of the model.ckpt which is of 2GB

To get the CID of the model.ckpt file go to https://gateway.ipfs.io/ipfs/< YOUR-OUTPUT-CID >/outputs/

https://gateway.ipfs.io/ipfs/QmcmD7M7pYLP8QgwjqpbP4dojRLiLuEBdhevuCD9kFmbdV/outputs/

If you use the Brave browser

ipfs://QmdpsqZn9BZx9XxzCsyPcJyS7yfYacmQXZxHzcuYwzmtGg/outputs

Using IPFS CLI

ipfs ls QmdpsqZn9BZx9XxzCsyPcJyS7yfYacmQXZxHzcuYwzmtGg/outputs

image

Copy the link of model.ckpt highlighted in the box https://gateway.ipfs.io/ipfs/QmdpsqZn9BZx9XxzCsyPcJyS7yfYacmQXZxHzcuYwzmtGg?filename=model.ckpt

Extract the CID portion of the link and copy it

Run the Bacalhau Job on the Fine-Tuned Model

To run a Bacalhau Job on the fine-tuned model, we will use the bacalhau docker run command.

%%bash --out job_id
bacalhau docker run \
--gpu 1 \
--timeout 3600 \
--wait-timeout-secs 3600 \
--wait \
--id-only \
-i ipfs://QmdpsqZn9BZx9XxzCsyPcJyS7yfYacmQXZxHzcuYwzmtGg \
jsacex/stable-diffusion-ckpt \
-- conda run --no-capture-output -n ldm python scripts/txt2img.py --prompt "a photo of aronchick drinking coffee" --plms --ckpt ../inputs/model.ckpt --skip_grid --n_samples 1 --skip_grid --outdir ../outputs

If you are facing difficulties using the above method you can mount the whole output CID

bacalhau docker run \
--gpu 1 \
--timeout 3600 \
--wait-timeout-secs 3600 \
--wait \
--id-only \
-i ipfs://QmcmD7M7pYLP8QgwjqpbP4dojRLiLuEBdhevuCD9kFmbdV \
jsacex/stable-diffusion-ckpt \
-- conda run --no-capture-output -n ldm python scripts/txt2img.py --prompt "a photo of aronchick drinking coffee" --plms --ckpt ../inputs/outputs/model.ckpt --skip_grid --n_samples 1 --skip_grid --outdir ../outputs

When a job is sumbitted, Bacalhau prints out the related job_id. We store that in an environment variable so that we can reuse it later on.

Checking the State of your Jobs

  • Job status: You can check the status of the job using bacalhau list.
%%bash
bacalhau list --id-filter ${JOB_ID} --wide

 CREATED  ID  JOB  STATE  VERIFIED  PUBLISHED   22-11-14-08:44:56  3c5e4faa-ab2e-4576-bd61-e31140493196  Docker jsacex/stable-diffusion-ckpt conda run --no-capture-output -n ldm python scripts/txt2img.py --prompt a photo of aronchick drinking coffee --plms --ckpt ../inputs/outputs/model.ckpt --skip_grid --n_samples 1 --skip_grid --outdir ../outputs  Completed   /ipfs/Qmep1mvj6RkyWa5Hptz6JhpAXAZziPDtStEopJjBYav6MM 

When it says Published or Completed, that means the job is done, and we can get the results.

  • Job information: You can find out more information about your job by using bacalhau describe.
%%bash
bacalhau describe ${JOB_ID}
  • Job download: You can download your job results directly by using bacalhau get. Alternatively, you can choose to create a directory to store your results. In the command below, we created a directory and downloaded our job output to be stored in that directory.
%%bash
rm -rf results && mkdir -p results
bacalhau get $JOB_ID --output-dir results
