DiffusionSat Custom Pipelines

Custom community pipelines for loading DiffusionSat checkpoints directly with diffusers.DiffusionPipeline.from_pretrained().

See Diffusers Community Pipeline Documentation.

Model Index

model_index.json is set to the default text-to-image pipeline (DiffusionSatPipeline) so DiffusionPipeline.from_pretrained() works out of the box. The ControlNet variant is loaded via custom_pipeline plus the controlnet subfolder, as shown below.

Available Pipelines

This directory contains two custom pipelines:

pipeline_diffusionsat.py: Standard text-to-image pipeline with DiffusionSat metadata support.
pipeline_diffusionsat_controlnet.py: ControlNet pipeline with DiffusionSat metadata and conditional metadata support.

Setup

The checkpoint folder (ckpt/diffusionsat/) should contain the standard diffusers components (unet, vae, scheduler, etc.). You can reference these pipeline files directly from this directory or copy them to your checkpoint folder.

Usage

1. Text-to-Image Pipeline

Use pipeline_diffusionsat.py for standard generation.

python

import torch
from diffusers import DDIMScheduler, DiffusionPipeline

# Load pipeline
pipe = DiffusionPipeline.from_pretrained(
    "path/to/ckpt/diffusionsat",
    custom_pipeline="./pipeline_diffusionsat.py",  # Path to this file
    torch_dtype=torch.float16,
    trust_remote_code=True,
)
pipe = pipe.to("cuda")
pipe.scheduler = DDIMScheduler.from_config(pipe.scheduler.config)

# Optional: Metadata (normalized lat, lon, timestamp, GSD, etc.)
# metadata = [0.5, -0.3, 0.7, 0.2, 0.1, 0.0, 0.5] 

# Generate
image = pipe(
    "satellite image of farmland",
    metadata=None,  # Optional
    height=512,
    width=512,
    num_inference_steps=50,
).images[0]
