# ImaginAIry 🤖🧠
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"
```
<details closed>
<summary>Console Output</summary>
```bash
🤖🧠 received 4 prompt(s) and will repeat them 1 times to create 4 images.

### Generate image captions
```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>`
## 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|stems",
mask_mode="replace",
mask_expansion=3
),
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 must be installed](https://www.rust-lang.org/tools/install)
to compile the `tokenizer` library.
be installed via: `curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh`
## 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)
## ChangeLog
**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
- 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
