ImaginAIry 🤖🧠
AI imagined images. Pythonic generation of stable diffusion images.
"just works" on Linux and macOS(M1) (and maybe windows?).
Examples
# on macOS, make sure rust is installed first
>> pip install imaginairy
>> imagine "a scenic landscape" "a photo of a dog" "photo of a fruit bowl" "portrait photo of a freckled woman"
Console Output
🤖🧠 received 4 prompt(s) and will repeat them 1 times to create 4 images.

Prompt Based Editing by clipseg
Specify advanced text based masks using boolean logic and strength modifiers. Mask descriptions must be lowercase. Keywords uppercase.
Valid symbols: AND
, OR
, NOT
, ()
, and mask strength modifier {*1.5}
where +
can be any of + - * /
. Single-character boolean
operators also work. When writing strength modifies know that pixel values are between 0 and 1.
>> imagine \
--init-image pearl_earring.jpg \
--mask-prompt "face AND NOT (bandana OR hair OR blue fabric){*6}" \
--mask-mode keep \
--init-image-strength .2 \
--fix-faces \
"a modern female president" "a female robot" "a female doctor" "a female firefighter"
>> imagine \
--init-image fruit-bowl.jpg \
--mask-prompt "fruit OR fruit stem{*6}" \
--mask-mode replace \
--mask-modify-original \
--init-image-strength .1 \
"a bowl of kittens" "a bowl of gold coins" "a bowl of popcorn" "a bowl of spaghetti"

Prompt Expansion
You can use {}
to randomly pull values from lists. A list of values separated by |
and enclosed in { }
will be randomly drawn from in a non-repeating fashion. Values that are surrounded by _ _
will
pull from a phrase list of the same name. Folders containing .txt phraselist files may be specified via
--prompt_library_path
. The option may be specified multiple times. Built-in categories:
3d-term, adj-architecture, adj-beauty, adj-detailed, adj-emotion, adj-general, adj-horror, animal, art-movement,
art-site, artist, artist-botanical, artist-surreal, aspect-ratio, bird, body-of-water, body-pose, camera-brand,
camera-model, color, cosmic-galaxy, cosmic-nebula, cosmic-star, cosmic-term, dinosaur, eyecolor, f-stop,
fantasy-creature, fantasy-setting, fish, flower, focal-length, food, fruit, games, gen-modifier, hair, hd,
iso-stop, landscape-type, national-park, nationality, neg-weight, noun-beauty, noun-fantasy, noun-general,
noun-horror, occupation, photo-term, pop-culture, pop-location, punk-style, quantity, rpg-item, scenario-desc,
skin-color, spaceship, style, tree-species, trippy, world-heritage-site
Examples:
imagine "a {lime|blue|silver|aqua} colored dog" -r 4 --seed 0
(note that it generates a dog of each color without repetition)
imagine "a {_color_} dog" -r 4 --seed 0
will generate four, different colored dogs. The colors will be pulled from an included
phraselist of colors.
imagine "a {_spaceship_|_fruit_|hot air balloon}. low-poly" -r 4 --seed 0
will generate images of spaceships or fruits or a hot air balloon

Generate image captions (via BLIP)
>> aimg describe assets/mask_examples/bowl001.jpg
a bowl full of gold bars sitting on a table
Features
- It makes images from text descriptions! 🎉
- Generate images either in code or from command line.
- It just works. Proper requirements are installed. model weights are automatically downloaded. No huggingface account needed. (if you have the right hardware... and aren't on windows)
- No more distorted faces!
- Noisy logs are gone (which was surprisingly hard to accomplish)
- WeightedPrompts let you smash together separate prompts (cat-dog)
- Tile Mode creates tileable images
- Prompt metadata saved into image file metadata
- Edit images by describing the part you want edited (see example above)
- Have AI generate captions for images
aimg describe <filename-or-url>
- Interactive prompt: just run
aimg
How To
For full command line instructions run aimg --help
from imaginairy import imagine, imagine_image_files, ImaginePrompt, WeightedPrompt, LazyLoadingImage
url = "https://upload.wikimedia.org/wikipedia/commons/thumb/6/6c/Thomas_Cole_-_Architect%E2%80%99s_Dream_-_Google_Art_Project.jpg/540px-Thomas_Cole_-_Architect%E2%80%99s_Dream_-_Google_Art_Project.jpg"
prompts = [
ImaginePrompt("a scenic landscape", seed=1, upscale=True),
ImaginePrompt("a bowl of fruit"),
ImaginePrompt([
WeightedPrompt("cat", weight=1),
WeightedPrompt("dog", weight=1),
]),
ImaginePrompt(
"a spacious building",
init_image=LazyLoadingImage(url=url)
),
ImaginePrompt(
"a bowl of strawberries",
init_image=LazyLoadingImage(filepath="mypath/to/bowl_of_fruit.jpg"),
mask_prompt="fruit OR stem{*2}", # amplify the stem mask x2
mask_mode="replace",
mask_modify_original=True,
),
ImaginePrompt("strawberries", tile_mode=True),
]
for result in imagine(prompts):
# do something
result.save("my_image.jpg")
# or
imagine_image_files(prompts, outdir="./my-art")
Requirements
- ~10 gb space for models to download
- A decent computer with either a CUDA supported graphics card or M1 processor.
- Python installed. Preferably Python 3.10.
- For macOS rust and setuptools-rust must be installed to compile the
tokenizer
library. They can be installed via:curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
andpip install setuptools-rust
Running in Docker
See example Dockerfile (works on machine where you can pass the gpu into the container)
docker build . -t imaginairy
# you really want to map the cache or you end up wasting a lot of time and space redownloading the model weights
docker run -it --gpus all -v $HOME/.cache/huggingface:/root/.cache/huggingface -v $HOME/.cache/torch:/root/.cache/torch -v `pwd`/outputs:/outputs imaginairy /bin/bash
Running on Google Colab
ChangeLog
3.1.0
- feature: img2img/inpainting supported on all samplers
- refactor: consolidates img2img/txt2img code. consolidates schedules. consolidates masking
- ci: minor logging improvements
3.0.1
- fix: k-samplers were broken
3.0.0
- feature: improved safety filter
2.4.0
- 🎉 feature: prompt expansion
- feature: make (blip) photo captions more descriptive
2.3.1
- fix: face fidelity default was broken
2.3.0
- feature: model weights file can be specified via
--model-weights-path
argument at the command line - fix: set face fidelity default back to old value
- fix: handle small images without throwing exception. credit to @NiclasEriksen
- docs: add setuptools-rust as dependency for macos
2.2.1
- fix: init image is fully ignored if init-image-strength = 0
2.2.0
- feature: face enhancement fidelity is now configurable
2.1.0
2.0.3
- fix memory leak in face enhancer
- fix blurry inpainting
- fix for pillow compatibility
2.0.0
- 🎉 fix: inpainted areas correlate with surrounding image, even at 100% generation strength. Previously if the generation strength was high enough the generated image would be uncorrelated to the rest of the surrounding image. It created terrible looking images.
- 🎉 feature: interactive prompt added. access by running
aimg
- 🎉 feature: Specify advanced text based masks using boolean logic and strength modifiers. Mask descriptions must be lowercase. Keywords uppercase.
Valid symbols:
AND
,OR
,NOT
,()
, and mask strength modifier{+0.1}
where+
can be any of+ - * /
. Single character boolean operators also work (|
,&
,!
) - 🎉 feature: apply mask edits to original files with
mask_modify_original
(on by default) - feature: auto-rotate images if exif data specifies to do so
- fix: mask boundaries are more accurate
- fix: accept mask images in command line
- fix: img2img algorithm was wrong and wouldn't at values close to 0 or 1
1.6.2
- fix: another bfloat16 fix
1.6.1
- fix: make sure image tensors come to the CPU as float32 so there aren't compatability issues with non-bfloat16 cpus
1.6.0
- fix: maybe address #13 with
expected scalar type BFloat16 but found Float
- at minimum one can specify
--precision full
now and that will probably fix the issue
- at minimum one can specify
- feature: tile mode can now be specified per-prompt
1.5.3
- fix: missing config file for describe feature
1.5.1
- img2img now supported with PLMS (instead of just DDIM)
- added image captioning feature
aimg describe dog.jpg
=>a brown dog sitting on grass
- added new commandline tool
aimg
for additional image manipulation functionality
1.4.0
- support multiple additive targets for masking with
|
symbol. Example: "fruit|stem|fruit stem"
1.3.0
- added prompt based image editing. Example: "fruit => gold coins"
- test coverage improved
1.2.0
- allow urls as init-images
previous
- img2img actually does # of steps you specify
- performance optimizations
- numerous other changes
Not Supported
