AI imagined images. Pythonic generation of stable diffusion images.
"just works" on Linux and macOS(M1) (and maybe windows?).
## Examples
```bash
# 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"
# Stable Diffusion 2.1
>> imagine --model SD-2.1 "a forest"
# Make generation gif
>> imagine --gif "a flower"
```

### 🎉 Edit Images with Instructions alone! [by InstructPix2Pix](https://github.com/timothybrooks/instruct-pix2pix)
Just tell imaginairy how to edit the image and it will do it for you!
Use prompt strength to control how strong the edit is. For extra control you can combine
with prompt-based masking.
```bash
# enter imaginairy shell
>> aimg
🤖🧠> edit scenic_landscape.jpg -p "make it winter" --prompt-strength 20
🤖🧠> edit scenic_landscape.jpg -p "make it winter" --steps 30 --arg-schedule "prompt_strength[2:25:0.5]" --compilation-anim gif
🤖🧠> edit dog.jpg -p "make the dog red" --prompt-strength 5
🤖🧠> edit bowl_of_fruit.jpg -p "replace the fruit with strawberries"
🤖🧠> edit freckled_woman.jpg -p "make her a cyborg" --prompt-strength 13
# create a comparison gif
🤖🧠> edit pearl_girl.jpg -p "make her wear clown makeup" --compare-gif
# create an animation showing the edit with increasing prompt strengths
🤖🧠> edit mona-lisa.jpg -p "make it a color professional photo headshot" --negative-prompt "old, ugly, blurry" --arg-schedule "prompt-strength[2:8:0.5]" --compilation-anim gif
```

### Prompt Based Masking [by clipseg](https://github.com/timojl/clipseg)
Specify advanced text based masks using boolean logic and strength modifiers.
Mask syntax:
- mask descriptions must be lowercase
- keywords (`AND`, `OR`, `NOT`) must be uppercase
- parentheses are supported
- mask modifiers may be appended to any mask or group of masks. Example: `(dog OR cat){+5}` means that we'll
select any dog or cat and then expand the size of the mask area by 5 pixels. Valid mask modifiers:
- `{+n}` - expand mask by n pixels
- `{-n}` - shrink mask by n pixels
- `{*n}` - multiply mask strength. will expand mask to areas that weakly matched the mask description
- `{/n}` - divide mask strength. will reduce mask to areas that most strongly matched the mask description. probably not useful
When writing strength modifiers keep in mind that pixel values are between 0 and 1.
```bash
>> 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"
```

#### 360 degree images
```bash
imagine --tile-x -w 1024 -h 512 "360 degree equirectangular panorama photograph of the desert" --upscale
```
<img src="assets/desert_360.jpg" height="128">
### Image-to-Image
Use depth maps for amazing "translations" of existing images.
```bash
>> imagine --model SD-2.0-depth --init-image girl_with_a_pearl_earring_large.jpg --init-image-strength 0.05 "professional headshot photo of a woman with a pearl earring" -r 4 -w 1024 -h 1024 --steps 50

<img src="assets/pearl_depth_1.jpg" height="512">
<img src="assets/pearl_depth_2.jpg" height="512">
<img src="assets/pearl_depth_3.jpg" height="512">
### Outpainting
Given a starting image, one can generate it's "surroundings".
Example:
`imagine --init-image pearl-earring.jpg --init-image-strength 0 --outpaint all250,up0,down600 "woman standing"`
<img src="https://raw.githubusercontent.com/brycedrennan/imaginAIry/master/tests/data/girl_with_a_pearl_earring.jpg" height="256"> ➡️
<img src="https://raw.githubusercontent.com/brycedrennan/imaginAIry/master/tests/expected_output/test_outpainting_outpaint_.png" height="256">
### 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)
<img src="https://raw.githubusercontent.com/brycedrennan/imaginAIry/master/assets/000184_0_plms40_PS7.5_a_silver_colored_dog_[generated].jpg" height="200"><img src="https://raw.githubusercontent.com/brycedrennan/imaginAIry/master/assets/000186_0_plms40_PS7.5_a_aqua_colored_dog_[generated].jpg" height="200">

<img src="https://raw.githubusercontent.com/brycedrennan/imaginAIry/master/assets/000211_0_plms40_PS7.5_a_blue_colored_dog_[generated].jpg" height="200">
`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](https://github.com/salesforce/BLIP))
```bash
>> 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`
- 🎉 finetune your own image model. kind of like dreambooth. Read instructions on ["Concept Training"](docs/concept-training.md) page
## How To
For full command line instructions run `aimg --help`
```python
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 CUDA supported graphics card with >= 11gb VRAM (and CUDA installed) or an M1 processor.
- Python installed. Preferably Python 3.10. (not conda)
- For macOS [rust](https://www.rust-lang.org/tools/install) 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` and `pip install setuptools-rust`
## Running in Docker
See example Dockerfile (works on machine where you can pass the gpu into the container)
```bash
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
[Example Colab](https://colab.research.google.com/drive/1rOvQNs0Cmn_yU1bKWjCOHzGVDgZkaTtO?usp=sharing)
## Q&A
**Q**: How do I change the cache directory for where models are stored?

- feature: xformers will be used if available (for faster generation)
- fix: version metadata was broken
**6.1.0**
- feature: use different default steps and image sizes depending on sampler and model selceted
- fix: #110 use proper version in image metadata
- refactor: samplers all have their own class that inherits from ImageSampler
- feature: 🎉🎉🎉 Stable Diffusion 2.0
- `--model SD-2.0` to use (it makes worse images than 1.5 though...)
- Tested on macOS and Linux
- All samplers working for new 512x512 model
- New inpainting model working
- 768x768 model working for all samplers except PLMS (`--model SD-2.0-v `)
**5.1.0**
- feature: add progress image callback
**5.0.1**
- fix: support larger images on M1. Fixes #8
- fix: support CPU generation by disabling autocast on CPU. Fixes #81
**5.0.0**
- feature: 🎉 inpainting support using new inpainting model from RunwayML. It works really well! By default, the
inpainting model will automatically be used for any image-masking task
- feature: 🎉 new default sampler makes image generation more than twice as fast
- feature: added `DPM++ 2S a` and `DPM++ 2M` samplers.
- feature: improve progress image logging
- fix: fix bug with `--show-work`. fixes #84
- fix: add workaround for pytorch bug affecting macOS users using the new `DPM++ 2S a` and `DPM++ 2M` samplers.
- fix: add workaround for pytorch mps bug affecting `k_dpm_fast` sampler. fixes #75
- fix: larger image sizes now work on macOS. fixes #8
**4.1.0**
- feature: allow dynamic switching between models/weights `--model SD-1.5` or `--model SD-1.4` or `--model path/my-custom-weights.ckpt`)
- feature: log total progress when generating images (image X out of Y)
**4.0.0**
- feature: stable diffusion 1.5 (slightly improved image quality)
- feature: dilation and erosion of masks
Previously the `+` and `-` characters in a mask (example: `face{+0.1}`) added to the grayscale value of any masked areas. This wasn't very useful. The new behavior is that the mask will expand or contract by the number of pixel specified. The technical terms for this are dilation and erosion. This allows much greater control over the masked area.
- feature: update k-diffusion samplers. add k_dpm_adaptive and k_dpm_fast
- 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**
- [improved masking accuracy from clipseg](https://github.com/timojl/clipseg/issues/8#issuecomment-1259150865)
**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 compatibility 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
- 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
