Skrample 0.7.0
Composable sampling functions for diffusion models
Status
Production-tested on all popular diffusion models. The library has significantly matured since 0.5
Quickstart
Fastest way to jump in is examples. The classes and functions themselves have docstrings and type hints, so it's recommended to make liberal use of your IDE or python help()
