dwave.cloud.client.Client.get_solver

Client.get_solver(name=None, refresh=False, **filters)

Load the configuration for a single solver.

Makes a blocking web call to {endpoint}/solvers/remote/{solver_name}/, where {endpoint} is a URL configured for the client, and returns a Solver instance that can be used to submit sampling problems to the D-Wave API and retrieve results.

Parameters:
  • name (str) – ID of the requested solver. None returns the default solver. If default solver is not configured, None returns the first available solver in Client’s class (QPU/software/base).
  • **filters (keyword arguments, optional) – Dictionary of filters over features this solver has to have. For a list of feature names and values, see: get_solvers().
  • order_by (callable/str, default='id') – Solver sorting key function (or Solver attribute name). By default, solvers are sorted by ID/name.
  • refresh (bool) – Return solver from cache (if cached with get_solvers()), unless set to True.
Returns:

Solver

Examples

This example creates two solvers for a client instantiated from a local system’s auto-detected default configuration file, which configures a connection to a D-Wave resource that provides two solvers. The first uses the default solver, the second explicitly selects another solver.
