"just works" on Linux and OSX(M1).

## Examples
```bash
>> pip install imaginairy
>> imagine "a scenic landscape" "a photo of a dog" "photo of a fruit bowl" "portrait photo of a freckled woman"
```

## 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

## How To

```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),
    ImaginePrompt("a bowl of fruit"),
    ImaginePrompt([
        WeightedPrompt("cat", weight=1),
        WeightedPrompt("dog", weight=1),
    ]),
    ImaginePrompt(
        "a spacious building", 
        init_image=LazyLoadingImage(url)
    )
]
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.

## 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
```

   - img2img for plms?
   - images as actual prompts instead of just init images
     - requires model fine-tuning since SD1.4 expects 77x768 text encoding input
