The Repo Formerly Known As "Dreambooth"
Notes by Joe Penna
INTRODUCTIONS!
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:
WARNING!
-
This is bleeding edge stuff... there is currently no easy way to run this. This repo is based on a repo based on another repo.
- At the moment, it takes a LOT of effort to create something that's basically duct tape and bubble gum -- but eventually works SUPER well.
- Step in, please! Don't let that scare ya -- but please know that you're wading through the jungle at night, with no torch...
-
Unfreezing the model takes a lot of juice.
You're gonna need an A6000 / A40 / A100 (or similar top-of-the-line thousands-of-dollars GPU).- 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
11-12GB
file 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
Setup
Easy RunPod Instructions
- 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).
- Click Deploy on either
SECURE CLOUD
orCOMMUNITY CLOUD
- Follow these video instructions here:
Vast.AI Instructions
- Sign up for Vast.AI
- Add some funds (I typically add them in $10 increments)
- Navigate to the Client - Create page
- 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)
- 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
- Navigate into the new
Dreambooth-Stable-Diffusion
directory on the left and open thedreambooth_runpod_joepenna.ipynb
file - Follow the instructions in the workbook and start training
Textual Inversion vs. Dreambooth
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.
Using the generated model
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 |
---|---|---|---|
![]() |
![]() |
![]() |
![]() |
Debugging your results
❗❗ THE NUMBER ONE MISTAKE PEOPLE MAKE ❗❗
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.
☢ Be careful with the types of images you train
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.
Oh no! You're not getting good generations!
OPTION 1: They're not looking like you at all! (Train longer, or get better training images)
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
