Run a Pipeline with Diffusers
Generate images from a pretrained model.
Run a Pipeline with Diffusers is a free Deep Learning Academy lesson on CoddyKit — lesson 4 of 4. You can read the complete lesson below for free — then practise it hands-on in the browser with a built-in code editor and a 24/7 AI tutor. It is part of the Deep Learning Academy learning path, one of 4 lessons in the course, and your progress syncs across the web and the CoddyKit app.
Meet Diffusers
Hugging Face Diffusers is the go-to library for running diffusion models. It wraps all the hard parts behind a friendly interface. 🤗
Install It
Getting started takes one pip install. You will also want transformers and accelerate alongside it for full support.
pip install diffusers transformers accelerateThe Pipeline Idea
A pipeline bundles the U-Net, scheduler, and text encoder into one object, so you call a single line to generate.
Load a Pretrained Model
You download weights straight from the Hub by name. No training needed; someone already did the heavy lifting for you.
pipe = DiffusionPipeline.from_pretrained(model_id)Move It to the GPU
Send the pipeline to your device so generation runs fast. On a CPU it works, but you will wait a while.
pipe = pipe.to("cuda")Generate from a Prompt
Call the pipeline with a text prompt and it returns an image. This is the whole magic in one friendly line.
image = pipe("a cozy cabin at sunset").images[0]Save Your Image
The result is a standard image object, so you can save it like any picture and open it anywhere. 💾
image.save("cabin.png")Tune the Knobs
Pass the parameters you learned, like inference steps and guidance scale, right into the call to shape the output.
pipe(prompt, num_inference_steps=30, guidance_scale=7.5)Reproducible Results
Set a seed with a generator and the same prompt yields the same image every time, which is great for comparing settings.
g = torch.Generator("cuda").manual_seed(42)Swap the Scheduler
You can switch the scheduler on a loaded pipeline to trade speed for quality without retraining anything.
From Theory to Pictures
With a few lines you turned all this theory into real images. The library handles the loop while you focus on prompts. 🎨

Recap
Load a pipeline, move it to your device, and call it with a prompt to generate. Tune steps, guidance, and seeds to control the result. 🎉
