All things D-Wave System.

Project description


dwave-system is a basic API for easily incorporating the D-Wave system as a sampler in the D-Wave Ocean software stack, directly or through Leap‘s cloud-based hybrid solvers. It includes DWaveSampler, a dimod sampler that accepts and passes system parameters such as system identification and authentication down the stack, LeapHybridSampler, for Leap’s hybrid solvers, and other. It also includes several useful composites—layers of pre- and post-processing—that can be used with DWaveSampler to handle minor-embedding, optimize chain strength, etc.


Installation from PyPI:

pip install dwave-system

Installation from PyPI with drivers:


Prior to v0.3.0, running pip install dwave-system installed a driver dependency called dwave-drivers (previously also called dwave-system-tuning). This dependency has a restricted license and has been made optional as of v0.3.0, but is highly recommended. To view the license details:

from dwave.drivers import __license__

To install with optional dependencies:

pip install dwave-system[drivers] --extra-index-url

Installation from source:

pip install -r requirements.txt
python install

Note that installing from source installs dwave-drivers. To uninstall the proprietary components:

pip uninstall dwave-drivers
