Hi! My name is Joe Penna.
You might have seen a few YouTube videos of mine under MysteryGuitarMan. I'm now a feature film director. You might have seen ARCTIC or STOWAWAY.
For my movies, I need to be able to train specific actors, props, locations, etc. So, I did a bunch of changes to @XavierXiao's repo in order to train people's faces.
I can't release all the tests for the movie I'm working on, but when I test with my own face, I release those on my Twitter page - @MysteryGuitarM.
Lots of these tests were done with a buddy of mine -- Niko from CorridorDigital. It might be how you found this repo!
I'm not really a coder. I'm just stubborn, and I'm not afraid of googling. So, eventually, some really smart folks joined in and have been contributing. In this repo, specifically: @djbielejeski @gammagec @MrSaad –– but so many others in our Discord!
This is no longer my repo. This is the people-who-wanna-see-Dreambooth-on-SD-working-well's repo!
Now, if you wanna try to do this... please read the warnings below first:
-
Let's respect the hard work and creativity of people who have spent years honing their skills.
- This iteration of Dreambooth was specifically designed for digital artists to train their own characters and styles into a Stable Diffusion model, as well as for people to train their own likenesses. My main goal is to make a tool for filmmakers to interact with concept artists that they've hired -- to generate the seed of an initial idea, so that they can then communicate visually. Meant to be used by filmmakers, concept artists, comic book designers, etc.
- One day, there'll be a Stable Diffussion trained on perfect datasets. In the meantime, for moral / ethical / potentially legal reasons, I strongly discourage training someone else's art into these model (unless you've obtained explicit permission, or they've made a public statement about this technology). For similar reasons, I recommend against using artists' names in your prompts. Don't put the people who made this possible out of the job!
-
Onto the technical side:
- You can now run this on a GPU with 24GB of VRAM (e.g. 3090). Training will be slower, and you'll need to be sure this is the only program running.
- If, like myself, you don't happen to own one of those, I'm including a Jupyter notebook here to help you run it on a rented cloud computing platform.
- It's currently tailored to runpod.io, but can work on vast.ai / etc.
-
This implementation does not fully implement Google's ideas on how to preserve the latent space.
- Most images that are similar to what you're training will be shifted towards that.
- e.g. If you're training a person, all people will look like you. If you're training an object, anything in that class will look like your object.
-
There doesn't seem to be an easy way to train two subjects consecutively. You will end up with an
11-12GBfile before pruning.- The provided notebook has a pruner that crunches it down to
~2gb
- The provided notebook has a pruner that crunches it down to
-
Best practice is to change the token to a celebrity name (note: token, not class -- so your prompt would be something like:
Chris Evans person). Here's my wife trained with the exact same settings, except for the token
Note (1/7/23) Runpod recently upgraded their base Docker image which breaks this repo by default. None of the Youtube videos are up to date, yet. Follow along the typical Runpod Youtube videos/tutorials, with the following changes:
From within the My Pods page,
- Click the menu button (to the left of the purple play button)
- Click Edit Pod
- Update "Docker Image Name" to say
runpod/pytorch. It shouldn't have any numbers or letters after it. - Click Save.
- Restart your pod
-
Sign up for RunPod. Feel free to use my referral link here, so that I don't have to pay for it (but you do).
-
After logging in, select either
SECURE CLOUDorCOMMUNITY CLOUD -
Make sure you find a "High" interent speed so you're not wasting time and money on slow downloads
-
Select something with at least 24gb VRAM like RTX 3090 or RTX A5000
-
Follow these video instructions below:
- Sign up for Vast.AI
- Add some funds (I typically add them in $10 increments)
- Navigate to the Client - Create page
- Select pytorch/pytorch as your docker image, and the buttons "Use Jupyter Lab Interface" and "Jupyter direct HTTPS"
- You will want to increase your disk space, and filter on GPU RAM (12gb checkpoint files + 4gb model file + regularization images + other stuff adds up fast)
- I typically allocate 150GB
- Also good to check the Upload/Download speed for enough bandwidth so you don't spend all your money waiting for things to download.
- Select the instance you want, and click
Rent, then head over to your Instances page and clickOpen
- You will get an unsafe certificate warning. Click past the warning or install the Vast cert.
- Click
Notebook -> Python 3(You can do this next step a number of ways, but I typically do this) - Clone Joe's repo with this command
!git clone https://github.com/JoePenna/Dreambooth-Stable-Diffusion.git- Click
run 
- Navigate into the new
Dreambooth-Stable-Diffusiondirectory on the left and open thedreambooth_runpod_joepenna.ipynbfile - Follow the instructions in the workbook and start training
The majority of the code in this repo was written by Rinon Gal et. al, the authors of the Textual Inversion research paper. Though a few ideas about regularization images and prior loss preservation (ideas from "Dreambooth") were added in, out of respect to both the MIT team and the Google researchers, I'm renaming this fork to: "The Repo Formerly Known As "Dreambooth"".
For an alternate implementation , please see "Alternate Option" below.
The ground truth (real picture, caution: very beautiful woman)
Same prompt for all of these images below:
sks person |
woman person |
Natalie Portman person |
Kate Mara person |
|---|---|---|---|
 |
 |
 |
 |
Prompting with just your token. ie "joepenna" instead of "joepenna person"
If you trained with joepenna under the class person, the model should only know your face as:
joepenna person
Example Prompts:
🚫 Incorrect (missing person following joepenna)
portrait photograph of joepenna 35mm film vintage glass
✅ This is right (person is included after joepenna)
portrait photograph of joepenna person 35mm film vintage glass
You might sometimes get someone who kinda looks like you with joepenna (especially if you trained for too many steps), but that's only because this current iteration of Dreambooth overtrains that token so much that it bleeds into that token.
While training, Stable doesn't know that you're a person. It's just going to mimic what it sees.
So, if these are your training images look like this:
You're only going to get generations of you outside next to a spiky tree, wearing a white-and-gray shirt, in the style of... well, selfie photograph.
Instead, this training set is much better:
The only thing that is consistent between images is the subject. So, Stable will look through the images and learn only your face, which will make "editing" it into other styles possible.
Are you sure you're prompting it right?
It should be <token> <class>, not just <token>. For example:
JoePenna person, portrait photograph, 85mm medium format photo
If it still doesn't look like you, you didn't train long enough.
OPTION 2: They're looking like you, but are all looking like your training images. (Train for less steps, get better training images, fix with prompting)
Okay, a few reasons why: you might have trained too long... or your images were too similar... or you didn't train with enough images.
No problem. We can fix that with the prompt. Stable Diffusion puts a LOT of merit to whatever you type first. So save it for later:
an exquisite portrait photograph, 85mm medium format photo of JoePenna person with a classic haircut
OPTION 3: They're looking like you, but not when you try different styles. (Train longer, get better training images)
You didn't train long enough...
No problem. We can fix that with the prompt:
JoePenna person in a portrait photograph, JoePenna person in a 85mm medium format photo of JoePenna person
