ImaginAIry 🤖🧠

AI imagined images. Pythonic generation of stable diffusion images.

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

Examples

Multiple Prompts

>> pip install imaginairy
>> imagine "a scenic landscape" "a photo of a dog" "photo of a fruit bowl" "portrait photo of a freckled woman"
🤖🧠 received 4 prompt(s) and will repeat them 1 times to create 4 images.

Features

• It makes images from text descriptions! 🎉
• Generate images either in code or from command line.
• It just works. Proper requirements installed, model weights 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)
• Tile Mode creates tileable images
• Prompt metadata saved into image file metadata

How To

from imaginairy import imagine_images, imagine_image_files, ImaginePrompt, WeightedPrompt

prompts = [
    ImaginePrompt("a scenic landscape", seed=1),
    ImaginePrompt("a bowl of fruit"),
    ImaginePrompt([
       WeightedPrompt("cat", weight=1),
       WeightedPrompt("dog", weight=1),
    ])
]
for result in imagine_images(prompts):
    # do something
    result.save("my_image.jpg")
    
# or

imagine_image_files(prompts, outdir="./my-art")

Requirements

• Computer with CUDA supported graphics card. ~10 gb video ram OR
