AI imagined images. Pythonic generation of stable diffusion images **and videos** *!.

"just works" on Linux and macOS(M1) (and sometimes windows).


```bash
# on macOS, make sure rust is installed first
# be sure to use Python 3.10, Python 3.11 is not supported at the moment
>> pip install imaginairy
>> imagine "a scenic landscape" "a photo of a dog" "photo of a fruit bowl" "portrait photo of a freckled woman" "a bluejay"
# Make an animation showing the generation process
>> imagine --gif "a flower"
# Make an AI video
>> aimg videogen --start-image rocket.png
```
## Stable Video Diffusion

### Whats New
**14.0.0**
- 🎉 video generation using [Stable Video Diffusion](https://github.com/Stability-AI/generative-models)
- 🎉 imaginairy is now backed by the [refiners library](https://github.com/finegrain-ai/refiners)
  - This was a huge re-write which is why some features are not yet supported.  On the plus side, refiners supports
cutting edge features (SDXL, image prompts, etc) which will be added to imaginairy soon.
  - [self-attention guidance](https://github.com/SusungHong/Self-Attention-Guidance) which makes details of images more accurate
- support for pytorch 2.0
- deprecated: support for python 3.8
- deprecated: support for torch 1.13
- deprecated: support for sd 1.4, 2.0, 2.1
- broken: pix2pix editing, most samplers, some controlnets, and memory management

### Run API server and StableStudio web interface (alpha)
Generate images via API or web interface.  Much smaller featureset compared to the command line tool.
```bash
>> aimg server
```
Visit http://localhost:8000/ and http://localhost:8000/docs
<img src="https://github.com/Stability-AI/StableStudio/blob/a65d4877ad7d309627808a169818f1add8c278ae/misc/GenerateScreenshot.png?raw=true">

### Image Structure Control [by ControlNet](https://github.com/lllyasviel/ControlNet)
#### (Broken as of 14.0.0)
Generate images guided by body poses, depth maps, canny edges, hed boundaries, or normal maps.

**Openpose Control**

```bash
imagine --control-image assets/indiana.jpg  --control-mode openpose --caption-text openpose "photo of a polar bear"
```

<p float="left">
    <img src="assets/indiana.jpg" height="256">
    <img src="assets/indiana-pose.jpg" height="256">
    <img src="assets/indiana-pose-polar-bear.jpg" height="256">
</p>

#### Canny Edge Control

```bash
imagine --control-image assets/lena.png  --control-mode canny "photo of a woman with a hat looking at the camera"
```

<p float="left">
    <img src="assets/lena.png" height="256">
    <img src="assets/lena-canny.jpg" height="256">
    <img src="assets/lena-canny-generated.jpg" height="256">
</p>

#### HED Boundary Control

```bash
imagine --control-image dog.jpg  --control-mode hed  "photo of a dalmation"
```

<p float="left">
    <img src="assets/000032_337692011_PLMS40_PS7.5_a_photo_of_a_dog.jpg" height="256">
    <img src="assets/dog-hed-boundary.jpg" height="256">
    <img src="assets/dog-hed-boundary-dalmation.jpg" height="256">
</p>

#### Depth Map Control

```bash
imagine --control-image fancy-living.jpg  --control-mode depth  "a modern living room"
```

<p float="left">
    <img src="assets/fancy-living.jpg" height="256">
    <img src="assets/fancy-living-depth.jpg" height="256">
    <img src="assets/fancy-living-depth-generated.jpg" height="256">
</p>

#### Normal Map Control

```bash
imagine --control-image bird.jpg  --control-mode normal  "a bird"
```

<p float="left">
    <img src="assets/013986_1_kdpmpp2m59_PS7.5_a_bluejay_[generated].jpg" height="256">
    <img src="assets/bird-normal.jpg" height="256">
    <img src="assets/bird-normal-generated.jpg" height="256">
</p>

#### Image Shuffle Control

Generates the image based on elements of the control image. Kind of similar to style transfer.
```bash
imagine --control-image pearl-girl.jpg  --control-mode shuffle  "a clown"
```
The middle image is the "shuffled" input image
<p float="left">
    <img src="assets/girl_with_a_pearl_earring.jpg" height="256">
    <img src="assets/pearl_shuffle_019331_1_kdpmpp2m15_PS7.5_img2img-0.0_a_clown.jpg" height="256">
    <img src="assets/pearl_shuffle_clown_019331_1_kdpmpp2m15_PS7.5_img2img-0.0_a_clown.jpg" height="256">
</p>

#### Editing Instructions Control

Similar to instructPix2Pix (below) but works with any SD 1.5 based model.
```bash
imagine --control-image pearl-girl.jpg  --control-mode edit --init-image-strength 0.01 --steps 30  --negative-prompt "" --model openjourney-v2 "make it anime" "make it at the beach" 
```

<p float="left">
    <img src="assets/girl_with_a_pearl_earring.jpg" height="256">
    <img src="assets/pearl_anime_019537_521829407_kdpmpp2m30_PS9.0_img2img-0.01_make_it_anime.jpg" height="256">
    <img src="assets/pearl_beach_019561_862735879_kdpmpp2m30_PS7.0_img2img-0.01_make_it_at_the_beach.jpg" height="256">
</p>

#### Add Details Control (upscaling/super-resolution)

Replaces existing details in an image. Good to use with --init-image-strength 0.2
```bash
imagine --control-image "assets/wishbone.jpg" --control-mode details "sharp focus, high-resolution" --init-image-strength 0.2 --steps 30 -w 2048 -h 2048 
```

<p float="left">
    <img src="assets/wishbone_headshot_badscale.jpg" height="256">
    <img src="assets/wishbone_headshot_details.jpg" height="256">
</p>


### Image (re)Colorization (using brightness control)
Colorize black and white images or re-color existing images.

The generated colors will be applied back to the original image. You can either provide a caption or 
allow the tool to generate one for you.

```bash
aimg colorize pearl-girl.jpg --caption "photo of a woman"
```
<p float="left">
    <img src="assets/girl_with_a_pearl_earring.jpg" height="256">
    <img src="assets/pearl-gray.jpg" height="256">
    <img src="assets/pearl-recolor-a.jpg" height="256">
</p>

###  Instruction based image edits [by InstructPix2Pix](https://github.com/timothybrooks/instruct-pix2pix)
#### (Broken as of 14.0.0)
Just tell imaginairy how to edit the image and it will do it for you!
<p float="left">
<img src="assets/scenic_landscape_winter.jpg" height="256">
<img src="assets/dog_red.jpg" height="256">
<img src="assets/bowl_of_fruit_strawberries.jpg" height="256">
<img src="assets/freckled_woman_cyborg.jpg" height="256">

<img src="assets/make-it-night-time.gif" height="256">
</p>

<details>
<summary>Click to see shell commands</summary>
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 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
🤖🧠> edit bluebird.jpg -p "make the bird wear a cowboy hat" --prompt-strength 10
🤖🧠> edit flower.jpg -p "make the flower out of paper origami" --arg-schedule prompt-strength[1:11:0.3]  --steps 25 --compilation-anim gif

# 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
🤖🧠> edit gg-bridge.jpg -p "make it night time" --prompt-strength 15  --steps 30 --arg-schedule prompt-strength[1:15:1] --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"
```

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" width="256">
<img src="assets/pearl_depth_2.jpg" width="256">
</p>


### 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="tests/data/girl_with_a_pearl_earring.jpg" height="256"> ➡️

    <img src="assets/fairytale-treehouse-openjourney-v1.jpg" height="256">
    <img src="assets/fairytale-treehouse-openjourney-v2.jpg" height="256">
</p>

<details>
<summary>Click to see shell command</summary>

```bash
imagine "valley, fairytale treehouse village covered, , matte painting, highly detailed, dynamic lighting, cinematic, realism, realistic, photo real, sunset, detailed, high contrast, denoised, centered, michael whelan" --steps 60 --seed 1 --arg-schedule model[sd14,sd15,sd20,sd21,openjourney-v1,openjourney-v2] --arg-schedule "caption-text[sd14,sd15,sd20,sd21,openjourney-v1,openjourney-v2]"
```
</details>

### 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-scene, 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, desktop-background, 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, painting-style, 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="assets/000184_0_plms40_PS7.5_a_silver_colored_dog_[generated].jpg" height="200"><img src="assets/000186_0_plms40_PS7.5_a_aqua_colored_dog_[generated].jpg" height="200">
<img src="assets/000210_0_plms40_PS7.5_a_lime_colored_dog_[generated].jpg" height="200">
<img src="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
```

### Example Use Cases

```bash
>> aimg
# Generate endless 8k art
🤖🧠> imagine -w 1920 -h 1080 --upscale "{_art-scene_}. {_painting-style_} by {_artist_}" -r 1000 --steps 30 --model sd21v

# generate endless desktop backgrounds 
🤖🧠> imagine --tile "{_desktop-background_}" -r 100

# convert a folder of images to pencil sketches
🤖🧠> edit other/images/*.jpg -p "make it a pencil sketch"

# upscale a folder of images
🤖🧠> upscale my-images/*.jpg

# generate kitchen remodel ideas
🤖🧠> imagine --control-image kitchen.jpg -w 1024 -h 1024 "{_interior-style_} kitchen" --control-mode depth -r 100 --init-image 0.01 --upscale --steps 35 --caption-text "{prompt}"
```

### Additional Features
 - 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)
 - Noisy logs are gone (which was surprisingly hard to accomplish)
 - WeightedPrompts let you smash together separate prompts (cat-dog)
 - Prompt metadata saved into image file metadata
 - 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

## 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?

A: Set the `HUGGINGFACE_HUB_CACHE` environment variable. 

#### Q: How do I free up disk space?

A: The AI models are cached in `~/.cache/` (or `HUGGINGFACE_HUB_CACHE`). To delete the cache remove the following folders:
 - ~/.cache/imaginairy
 - ~/.cache/clip
 - ~/.cache/torch
 - ~/.cache/huggingface


## ChangeLog

**14.0.0**
- 🎉 feature: video generation using [Stable Video Diffusion](https://github.com/Stability-AI/generative-models)
- 🎉 feature: imaginairy is now backed by the [refiners library](https://github.com/finegrain-ai/refiners)
  - This was a huge re-write which is why some features are not yet supported.  On the plus side, refiners supports
cutting edge features (SDXL, image prompts, etc) which will be added to imaginairy soon.
  - feature: added support for [self-attention guidance](https://github.com/SusungHong/Self-Attention-Guidance) which makes details of images more accurate
- feature: adds support for pytorch 2.0
- deprecated: support for python 3.8
- deprecated: support for torch 1.13
- deprecated: support for sd 1.4, 2.0, 2.1

  - 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

 - 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

**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

**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
