dwave-system 1.34.0

All things D-Wave System.

dwave-system

dwave-system is a basic API for easily incorporating the D-Wave system as a sampler in the Ocean software stack, directly or through Leap service’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 others. 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

Installation from PyPI:

pip install dwave-system

Note

As of dwave-system 1.28.0, support for dwave-drivers is removed (it was used for calibration of qubits in chains via VirtualGraphComposite, but it’s no longer required due to improved calibration of newer QPUs).

Installation from source:

pip install -r requirements.txt
python setup.py install
