Installation

sequince requires Python 3.11 or later. Install it from PyPI:

python -m pip install sequince

The core installation includes NumPy, SciPy, MiniPCN, and the Array API compatibility packages. It supports NumPy-based sampling with the default MiniPCN mutation backend.

Optional integrations

Install extras for the integrations you need, for example:

python -m pip install "sequince[jax,blackjax,hdf5]"

Extra	Provides
jax	JAX arrays and functional execution
blackjax	BlackJAX mutation algorithms
emcee	emcee ensemble mutation
eryn	Eryn ensemble mutation
hdf5	HDF5 result storage and checkpointing
corner	Corner plots

For example, install sequince[emcee] to select emcee mutation instead of the default MiniPCN backend. See Mutation configuration for mutation-specific requirements.

See Array backends for backend selection, accelerator setup, and SciPy Array API configuration.
